Show a snackbar to a menu click event in Android

Question

I have a menu on android and want to show a simple snackbar anywhere after there was a click on a menu item. Whatever I put something else instead of "???" doesn't work. The whole app is from the Android studio default tab view template. This is the code I have:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        Snackbar.make("????", "Pressed Setting", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
    }
    if (id == R.id.help_settings) {
        Snackbar.make("???", "Pressed Help", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
    }
    return super.onOptionsItemSelected(item);
}

Why is it behaving like that? And how can I fix it?

Answer 1

Change

Snackbar.make("???", ....)

to

Snackbar.make(getWindow().getDecorView(), .....);

You must pass in a View to the Snackbar's static make method.

EDIT:

On some devices the snackbar can appear below the system's controls menu, and for that reason you may wanna call findViewById(android.R.id.content) to display the snackbar correctly:

Snackbar.make(getWindow().getDecorView().findViewById(android.R.id.content), .....);

Answer 2

This is how you show Snackbar on menu item click:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        Snackbar.make(this.findViewById(R.id.action_settings), "Pressed Setting", Snackbar.LENGTH_LONG).show();
    }
    if (id == R.id.help_settings) {
        Snackbar.make(this.findViewById(R.id.help_settings), "Pressed Help", Snackbar.LENGTH_LONG).show();
    }
    return super.onOptionsItemSelected(item);
}
