Show keyboard for edittext when fragment starts

2020-02-03 09:38发布

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?

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();

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);
}

/**

@Override
public InputConnection onCreateInputConnection(EditorInfo editorInfo) {
    final InputConnection ic = super.onCreateInputConnection(editorInfo);
    if (mHasPendingShowSoftInputRequest) {
        removeCallbacks(mRunShowSoftInputIfNecessary);
        post(mRunShowSoftInputIfNecessary);
    }
    return ic;
}

private void showSoftInputIfNecessary() {
    if (mHasPendingShowSoftInputRequest) {
        final InputMethodManager imm =
                getContext().getSystemService(InputMethodManager.class);
        imm.showSoftInput(this, 0);
        mHasPendingShowSoftInputRequest = false;
    }
}

public void scheduleShowSoftInput() {
    final InputMethodManager imm = getContext().getSystemService(InputMethodManager.class);
    if (imm.isActive(this)) {
        // This means that ImeAwareEditText is already connected to the IME.
        // InputMethodManager#showSoftInput() is guaranteed to pass client-side focus check.
        mHasPendingShowSoftInputRequest = false;
        removeCallbacks(mRunShowSoftInputIfNecessary);
        imm.showSoftInput(this, 0);
        return;
    }

    // Otherwise, InputMethodManager#showSoftInput() should be deferred after
    // onCreateInputConnection().
    mHasPendingShowSoftInputRequest = true;

    @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);

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! :-)

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);
        }
    });
}

As Nilzor said this works

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

and I agree it is a best solution than toogleSoftInput
