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

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, although the EditText is in focus, unless you explicitly touch it again.

Is there a way to force it to pop?

I've tried the following, after the (AlertDialog.Builder).show(); but for no avail.

InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(input, InputMethodManager.SHOW_FORCED);

Anyone can help?

Thanks!!

When you call showDialog() to show a Dialog created using AlertDialog in onCreateDialog()

You should put the code in onPrepareDialog():

@Override
protected void onPrepareDialog (int id, Dialog dialog, Bundle args)
{
    TextView editText=(TextView) dialog.findViewById(R....);

    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
       @Override
       public void onFocusChange(View v, boolean hasFocus) {
         if (hasFocus) {
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
         }
       }
    });
}

In my case, the SoftInputMode wasn't getting displayed when I set it which was before showing the dialog (after creating it). The below code worked for me where I set the SoftInputMode after showing the dialog.

Kotlin:

val dialog = MaterialAlertDialogBuilder(context) // Other builder code
                .create()
dialog.show()
dialog.window?.apply { // After the window is created, get the SoftInputMode
    clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE)
    clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM)
    setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE)
}

Java:

AlertDialog dialog = MaterialAlertDialogBuilder(getContext()) // Other builder code
                .create();
dialog.show();
Window window = dialog.getWindow();
if(window != null){ // After the window is created, get the SoftInputMode
    window.clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    window.clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
    window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}

I hope this helps anyone who was having the same problem as me.

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);
    }
});

Try this, its working for me

    Window window = dialog.getWindow();
    if (window != null) { // After the window is created, get the SoftInputMode
        window.clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
        window.clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
        window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    }

I found an easy and reliable solution to this, just put a hidden EditText on root of your dialog layout if you got a complex layout which an editable field isn't in root,

<!-- Just to trick AlertDialog to not hide soft keyboard -->
<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:visibility="gone" />

This is basically to trick this part of compat/androidx.

I used to use onResume solution above but with that I couldn't use simpler API of AlertDialog.Builder() to remove the use of AppCompatDialogFragment but now I can simply use the easier API.
