How to show soft-keyboard when edittext is focused

2019-01-01 09:27发布

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:

  1. 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).

  2. 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.

code snippet . . .

public void hideKeyboard(Context activityContext){

    InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    //android.R.id.content ( http://stackoverflow.com/a/12887919/2077479 )
    View rootView = ((Activity) activityContext)
            .findViewById(android.R.id.content).getRootView();

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

public void showKeyboard(Context activityContext, final EditText editText){

    final InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    if (!editText.hasFocus()) {
        editText.requestFocus();
    }

    editText.post(new Runnable() {
        @Override
        public void run() {
            imm.showSoftInput(editText, InputMethodManager.SHOW_FORCED);
        }
    });
}

 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);

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);

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;
  }

It worked for me. You can try with this also to show the keyboard:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

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);
}

}
