问题:
I want to automatically show the soft-keyboard when an EditText
is focused (if the device does not have a physical keyboard) and I have two problems:
When my Activity
is displayed, my EditText
is focused but the keyboard is not displayed, I need to click again on it to show the keyboard (it should be displayed when my Activity
is displayed).
And when I click done on the keyboard, the keyboard is dissmissed but the EditText
stays focused and y don\'t want (because my edit is done).
To resume, my problem is to have something more like on the iPhone: which keep the keyboard sync with my EditText
state (focused / not focused) and of course does not present a soft-keyboard if there is a physical one.
回答1:
To force the soft keyboard to appear, you can use
EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);
And for removing the focus on EditText
, sadly you need to have a dummy View
to grab focus.
I hope this helps
To close it you can use
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(yourEditText.getWindowToken(), 0);
This works for using it in a dialog
public void showKeyboard(){
InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
public void closeKeyboard(){
InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}

I had the same problem. Immediately after editText VISIBILITY change from GONE to VISIBLE, I had to set the focus and display the soft keyboard. I achieved this using the following code:
new Handler().postDelayed(new Runnable() {
public void run() {
// ((EditText) findViewById(R.id.et_find)).requestFocus();
//
EditText yourEditText= (EditText) findViewById(R.id.et_find);
// InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
// imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);
yourEditText.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN , 0, 0, 0));
yourEditText.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP , 0, 0, 0));
}
}, 200);
It works for me with 100ms delay, but failed without any delay or with only a delay of 1ms.
Commented part of code shows another approach, which works only on some devices. I tested on OS versions 2.2 (emulator), 2.2.1 (real device) and 1.6 (emulator).
This approach saved me a lot of pain.
回答3:
To cause the keyboard to appear, use
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
This method is more reliable than invoking the InputMethodManager directly.
To close it, use
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

The following code is pillaged from the Google\'s 4.1 source code for SearchView. Seems to work, fine on lesser versions of Android as well.
private Runnable mShowImeRunnable = new Runnable() {
public void run() {
InputMethodManager imm = (InputMethodManager) getContext()
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.showSoftInput(editText, 0);
}
}
};
private void setImeVisibility(final boolean visible) {
if (visible) {
post(mShowImeRunnable);
} else {
removeCallbacks(mShowImeRunnable);
InputMethodManager imm = (InputMethodManager) getContext()
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(getWindowToken(), 0);
}
}
}
Then in addition, the following code needs to be added as the Control/Activity is created. (In my case it\'s a composite control, rather than an activity).
this.editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
setImeVisibility(hasFocus);
}
});
回答5:
When nothing else works, force it to be shown:
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
回答6:
android:windowSoftInputMode=\"stateAlwaysVisible\"
-> in manifest File.
edittext.requestFocus();
-> in code.
This will open soft keyboard on which edit-text has request focus as activity appears.
回答7:
I have had some recent luck in some simple cases with the code
below. I haven\'t finished all testing but....
EditText input = (EditText) findViewById(R.id.Input);
input.requestFocus();
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN , 0, 0, 0));
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP , 0, 0, 0));
And presto the keyboard shows up.
回答8:
You can try to force the soft keyboard to appear, it works for me:
...
dialog.show();
input.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
回答9:
To hide keyboard, use this one:
getActivity().getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
and to show keyboard:
getActivity().getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
回答10:
Sometimes raukodraug\'s answer won\'t work. I\'ve make it in this way with some trials and errors:
public static void showKeyboard(Activity activity) {
if (activity != null) {
activity.getWindow()
.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}
public static void hideKeyboard(Activity activity) {
if (activity != null) {
activity.getWindow()
.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
}
And the EditText part:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
hideKeyboard(getActivity());
} else {
showKeyboard(getActivity());
}
}
});
回答11:
showSoftInput
was not working for me at all.
I figured I needed to set the input mode: (here in the Activity component in the manifest)
android:windowSoftInputMode=\"stateVisible\"
回答12:
For fragment, sure its working:
displayName = (EditText) view.findViewById(R.id.displayName);
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
回答13:
I combined everything here and for me it works:
public static void showKeyboardWithFocus(View v, Activity a) {
try {
v.requestFocus();
InputMethodManager imm = (InputMethodManager) a.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
a.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
} catch (Exception e) {
e.printStackTrace();
}
}
回答14:
Believe or not my problem with Soft Keyboard was resolved when I discovered that the Activities animations can disable the Soft Keyboard. When you call the intent with the
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
and
overridePendingTransition(0, 0);
It can hide the Soft Keyboard and there isn\'t a way to show it.
回答15:
I had the same problem in various different situations, and the solutions i have found work in some but dont work in others so here is a combine solution that works in most situations i have found:
public static void showVirtualKeyboard(Context context, final View view) {
if (context != null) {
final InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
view.clearFocus();
if(view.isShown()) {
imm.showSoftInput(view, 0);
view.requestFocus();
} else {
view.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
@Override
public void onViewAttachedToWindow(View v) {
view.post(new Runnable() {
@Override
public void run() {
view.requestFocus();
imm.showSoftInput(view, 0);
}
});
view.removeOnAttachStateChangeListener(this);
}
@Override
public void onViewDetachedFromWindow(View v) {
view.removeOnAttachStateChangeListener(this);
}
});
}
}
}

回答17:
It worked for me. You can try with this also to show the keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
回答18:
just add android:windowSoftInputMode=\"stateHidden\" in manifest file...
回答19:
final InputMethodManager keyboard = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
回答20:
editText.post(new Runnable() {
@Override
public void run() {
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
}
});
回答21:
All solutions given above (InputMethodManager interaction in OnFocusChangeListener.onFocusChange listener attached to your EditText works fine if you have single edit in the activity.
In my case I have two edits.
private EditText tvX, tvY;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tvX.setOnFocusChangeListener(this);
tvY.setOnFocusChangeListener(this);
@Override
public void onFocusChange(View v, boolean hasFocus) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if(tvX.hasFocus() || tvY.hasFocus()) {
imm.showSoftInput(v, 0);
} else {
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
};
I have observed that onFocusChange is triggered for tvX with hasFocus=true (keyboard shown) but then for tvY with hasFocus=true (keyboard hidden). In the end, no keyboard was visible.
General solution should have correct statement in if \"show keyboard if EditText text has focus\"
回答22:
In your onResume() section of the Activity you can do call the method bringKeyboard();
onResume() {
EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
bringKeyboard(yourEditText);
}
protected boolean bringKeyboard(EditText view) {
if (view == null) {
return false;
}
try {
// Depending if edittext has some pre-filled values you can decide whether to bring up soft keyboard or not
String value = view.getText().toString();
if (value == null) {
InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
return true;
}
} catch (Exception e) {
Log.e(TAG, \"decideFocus. Exception\", e);
}
return false;
}
回答23:
Inside your manifest:
android:windowSoftInputMode=\"stateAlwaysVisible\"
- initially launched keyboard.
android:windowSoftInputMode=\"stateAlwaysHidden\"
- initially hidden keyboard.
I like to use also \"adjustPan\"
because when the keyboard launches then the screen auto adjusts.
<activity
android:name=\"YourActivity\"
android:windowSoftInputMode=\"stateAlwaysHidden|adjustPan\"/>
回答24:
I discovered a strange behaviour, since in one of my apps, the soft keyboard was automatically showing on entering the activity (there is an editText.requestFocus() in onCreate).
On digging further, I discovered that this was because there is a ScrollView around the layout. If I remove the ScrollView, the behaviour is as described in the original problem statement: only on clicking the already focused editText does the soft keyboard show up.
If it doesn\'t work for you, try putting in a ScrollView -- it\'s harmless anyway.
回答25:
I had a similar problem using view animations. So I\'ve put an animation listener to make sure I\'d wait for the animation to end before trying to request a keyboard access on the shown edittext.
bottomUp.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
if (textToFocus != null) {
// Position cursor at the end of the text
textToFocus.setSelection(textToFocus.getText().length());
// Show keyboard
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(textToFocus, InputMethodManager.SHOW_IMPLICIT);
}
}
@Override
public void onAnimationRepeat(Animation animation) {
}
});
回答26:
I am agree with raukodraug therefor using in a swithview you must request/clear focus like this :
final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);
final View btn = viewSwitcher.findViewById(R.id.address_btn);
final View title = viewSwitcher.findViewById(R.id.address_value);
title.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
viewSwitcher.showPrevious();
btn.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(btn, InputMethodManager.SHOW_IMPLICIT);
}
});
// EditText affiche le titre evenement click
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
btn.clearFocus();
viewSwitcher.showNext();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(btn.getWindowToken(), 0);
// Enregistre l\'adresse.
addAddress(view);
}
});
Regards.
回答27:
Using Xamarin, this works for me inside a Fragment:
using Android.Views.InputMethods;
using Android.Content;
...
if ( _txtSearch.RequestFocus() ) {
var inputManager = (InputMethodManager) Activity.GetSystemService( Context.InputMethodService );
inputManager.ShowSoftInput( _txtSearch, ShowFlags.Implicit );
}
回答28:
I made this help class.
Just pass the context and the View you want to focus and show keyboard and after hide keyboard.
I hope it Helps.
public class FocusKeyboardHelper {
private View view;
private Context context;
private InputMethodManager imm;
public FocusKeyboardHelper(Context context, View view){
this.view = view;
this.context = context;
imm = (InputMethodManager) context.getSystemService(context.INPUT_METHOD_SERVICE);
}
public void focusAndShowKeyboard(){
view.requestFocus();
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
}
public void hideKeyBoard(){
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
回答29:
void requestFocus(View editText, Activity activity)
{
try {
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) a.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
} catch (Exception e) {
e.printStackTrace();
}
}
add this line too do not forget
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

You can also create a custom extension of the EditText that knows to open the soft keyboard when it receives focus. That\'s what I\'ve ended up doing. Here\'s what worked for me:
public class WellBehavedEditText extends EditText {
private InputMethodManager inputMethodManager;
private boolean showKeyboard = false;
public WellBehavedEditText(Context context) {
super(context);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes) {
super(context, attributes);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes, int defStyleAttr) {
super(context, attributes, defStyleAttr);
this.initializeWellBehavedEditText(context);
}
public WellBehavedEditText(Context context, AttributeSet attributes, int defStyleAttr, int defStyleRes) {
super(context, attributes, defStyleAttr, defStyleRes);
this.initializeWellBehavedEditText(context);
}
private void initializeWellBehavedEditText(Context context) {
this.inputMethodManager = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
final WellBehavedEditText editText = this;
this.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
if(showKeyboard) {
showKeyboard = !(inputMethodManager.showSoftInput(editText, InputMethodManager.SHOW_FORCED));
}
}
});
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(!focused) this.showKeyboard = false;
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public boolean requestFocus(int direction, Rect previouslyFocusedRect) {
boolean result = super.requestFocus(direction, previouslyFocusedRect);
this.showKeyboard = true;
final WellBehavedEditText self = this;
this.post(new Runnable() {
@Override
public void run() {
showKeyboard = !(inputMethodManager.showSoftInput(self, InputMethodManager.SHOW_FORCED));
}
});
return result;
}
}
