when using AlertDialog.Builder with EditText, the Soft Keyboard doesn't pop

Question

I am using AlertDialog.Builder in order to create an input box, with EditText as the input method.

Unfortunately, the Soft Keyboard doesn\'t pop, al

Answer 1

This problem occurs when EditText is added after AlertDialog.onCreate is called.

https://developer.android.com/reference/androidx/appcompat/app/AlertDialog.Builder

The AlertDialog class takes care of automatically setting android.view.WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM for you based on whether any views in the dialog return true from View.onCheckIsTextEditor().

You need to clear the FLAG_ALT_FOCUSABLE_IM flag.

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM); 

Because AlertDialog.show is called in the DialogFragment.onStart, you can insert the code in the DialogFragment.onStart.

@Override
public void onStart() {
    super.onStart();
    getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
}

Or you can use the Dialog.setOnShowListener if you do not use a DialogFragment.

dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    }
});

Answer 2

Window window = dialog.getWindow();
    window.clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

Answer 3

I've made such a thing

AlertDialog.Builder b = new AlertDialog.Builder(this);//....
AlertDialog dialog = b.create();

dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

dialog.show();

This was answered here already. Using an OnFocusChangeListener worked for me.

Answer 5

Try this, its working for me

If you want to display soft keyboard:

InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.showSoftInput(input.getWindowToken(), 0);

And if you want to hide the it:

  InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(input.getWindowToken(), 0);

Answer 6

I found out that the same code works properly on Tablet, the keyboard does pop up, but on Phone it doesn't, so researching further, seems to point to the "adjust" option.

I am using this, feels much cleaner.

AlertDialog d = builder.create();
d.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
d.show();
