Question

For some reason I can’t create a context menu.

I have these lines in onCreate:

btnMenu = (ImageButton) findViewById(R.id.btnMenu);

registerForContextMenu(btnMenu);

And added the method:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.mainmenu, menu);
}

I have an xml file in res/menu called mainmenu:

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@+id/new_game"
    android:title="item1"
    />
    <item android:id="@+id/help"
    android:title="item2" 
    />

</menu>

But when I click the imagebutton nothing appears.

Any help is appreciated.

I’ve tried your code, and it worked great. Be careful, you need a long press on the view (in this example on the button), not a short click. If you want to show the context menu for a short click, try something like this:

Button b = (Button) findViewById(R.id.button1);

registerForContextMenu(b);

b.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
    v.showContextMenu();
}   
});
