Show keyboard for edittext when fragment starts

问题:

When my fragment starts, I want my edittext to be in focus/let user to just start typing in it. I am able to get it in focus with requestFocus(), but I cannot get the keyboard to show up.

I have tried both this:

edit = (EditText) view.findViewById(R.id.search);
edit.requestFocus();
InputMethodManager imgr = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imgr.showSoftInput(edit, 0);

and

edit = (EditText) view.findViewById(R.id.search);
InputMethodManager imgr = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imgr.showSoftInput(edit, 0);
edit.requestFocus();

How can I get the keyboard to show up for EditText?

回答1:

Does this work?

imgr.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

回答2:

You can try this

@Override
public void onResume() {
    super.onResume();
    edit.post(new Runnable() {
        @Override
        public void run() {
            edit.requestFocus();
            InputMethodManager imgr = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            imgr.showSoftInput(edit, InputMethodManager.SHOW_IMPLICIT);
        }
    });
}

回答3:

Since using showSoftInput doesn't work for all cases and after trying some of the solutions mentioned here, like:

if (binding.account.requestFocus()) {
  getActivity().getWindow()
      .setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
}

I finally made it work using:

if (binding.account.requestFocus()) {
  ((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(
      InputMethodManager.SHOW_FORCED,
      InputMethodManager.HIDE_IMPLICIT_ONLY
  );
}

Since:

 binding.account.requestFocus()

only request the focus for the EditText (it doesn't open the keyboard)

and

((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(
      InputMethodManager.SHOW_FORCED,
      InputMethodManager.HIDE_IMPLICIT_ONLY
  );

is the only solution that appears to be working correctly to show the keyboard (and the most voted one)

Good luck! :-)

I have helpful extension for that:

fun EditText.showKeyboard() {
    if (requestFocus()) {
        (getActivity()?.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager)
            .showSoftInput(this, SHOW_IMPLICIT)
        setSelection(text.length)
    }
}

You will also need this one:

fun View.getActivity(): AppCompatActivity?{
    var context = this.context
    while (context is ContextWrapper) {
        if (context is AppCompatActivity) {
            return context
        }
        context = context.baseContext
    }
    return null
}

回答5:

    @Override
public void onHiddenChanged (boolean hidden)
{
    super.onHiddenChanged(hidden);

    if(hidden)
    {
        hideKeyboard(yourView);
    }
    else
    {
        toggleKeyboard(yourView);
    }
}

    public static void toggleKeyboard(View v)
{
    InputMethodManager imm = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    v.requestFocus();

    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_NOT_ALWAYS);
}

public static void hideKeyboard(View v)
{
    InputMethodManager imm = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);

    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}

After trying all solutions here and on other questions related, Here's the method that works for me:

editText.postDelayed(Runnable { showKeyboard(activity, editText)} , 50)


fun showKeyboard(activity: Activity, editText: EditText) {
    val inputMethodManager = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    editText.requestFocus()
    inputMethodManager.showSoftInput(this, 0)
}

The fun fact is when you call it without postDeleayed it won't work, even if you just delay it for 1 millisecond it still won't work :D

You can also use it as an extension like this:

fun EditText.showKeyboard(activity: Activity) {
    val inputMethodManager = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    requestFocus()
    inputMethodManager.showSoftInput(this, 0)
}

if you don't like to pass activity as a parameter, you use this extension function as @Rafols suggests:

fun View.getActivity(): AppCompatActivity? {
    var context = this.context
    while (context is ContextWrapper) {
        if (context is AppCompatActivity) {
            return context
        }
        context = context.baseContext
    }
    return null
}

then your method will look like this:

fun EditText.showKeyboard() {
    val inputMethodManager = getActivity()!!.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    requestFocus()
    inputMethodManager.showSoftInput(this, 0)
}

also if you have a text already in your EditText, its better set selection at the end of your existing text:

fun EditText.showKeyboard() {
    val inputMethodManager = getActivity()!!.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    requestFocus()
    inputMethodManager.showSoftInput(this, 0)
    setSelection(length())
}

and if you want to start it when fragment starts:

override fun onResume() {
    super.onResume()
    editText.postDelayed(Runnable { editText.showKeyboard()} , 50)
}

回答7:

Another way to make the keyboard open when your fragment starts is to call requestFocus() in onCreateView and react accordingly by opening the keyboard if and only if the EditText is focusable.

if(this.editText.requestFocus())
{
    getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
}

回答8:

EditText.requestFocus() + InputMethodManager.showSoftInput() = Show IME for EditText

use EditText.performAccessibilityAction(AccessibilityNodeInfo.ACTION_CLICK, null) in Fragment.onViewCreated() instead

    void maybeShowInputMethod() {
        // use addOnPreDrawListener instead of addOnGlobalLayoutListener
        // because execute sequence: onGlobalLayout-> Restore focus -> onPreDraw
        getView().getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {

            @Override
            public boolean onPreDraw() {
                // TODO Auto-generated method stub
                getView().getViewTreeObserver().removeOnPreDrawListener(this);

                // always requestFocus when fragment enter or show
                getView().requestFocus();
                final View currentFocus = getView().findFocus();
                if ((currentFocus != null) && currentFocus.onCheckIsTextEditor()) {
                    Log.d(TAG, "maybeShowInputMethod:: currentFocus=" + currentFocus);
                    currentFocus.performAccessibilityAction(AccessibilityNodeInfo.ACTION_CLICK, null);
                }
                return true;
            }
        });
    }

or create subclass of EditText and override public InputConnection onCreateInputConnection(EditorInfo editorInfo)

public class ImeAwareEditText extends EditText {
private boolean mHasPendingShowSoftInputRequest;
final Runnable mRunShowSoftInputIfNecessary = () -> showSoftInputIfNecessary();

public ImeAwareEditText(Context context) {
    super(context, null);
}

public ImeAwareEditText(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ImeAwareEditText(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

public ImeAwareEditText(Context context, AttributeSet attrs, int defStyleAttr,
        int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
}

As Nilzor said this works

imgr.showSoftInput(getView(), InputMethodManager.SHOW_IMPLICIT)

and I agree it is a best solution than toogleSoftInput

this article helped me

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) 
{
  View view = inflater.inflate(R.layout.fragment_edit_name, container);
  editText = (EditText) view.findViewById(R.id.txt_yourName);
  editText.requestFocus();
  getDialog().getWindow().setSoftInputMode(
                       LayoutParams.SOFT_INPUT_STATE_VISIBLE);
   return view;
}

Simply, using adding 2 lines will work like a charm:

If using XML

android:focusable="true"
android:focusableInTouchMode="true"

Else in Java:

view.setFocusableInTouchMode(true);
view.requestFocus();
