Click EditText can't popup softkeyboard

Question

I open a Activity with a EditText, when I stay in this Activity, a Service in background start a new other Activity with flags:

intent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT
            | Intent.FLAG_ACTIVITY_NEW_TASK);

when the new Activity is closed, the softkeyboard can't show anymore when click the editText.

Answer 1

You can Try this once it works for me.

final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
final EditText input = new EditText(getActivity());
alert.setView(input);
final AlertDialog dialog = alert.show();
input.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
         if(hasFocus) {
             dialog.getWindow().setSoftInputMode(
                 WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE
             );
         }
    }
});
