Change toolbar button behaviour in android

Question

I implemented a Side Drawer that opens from right to left. Now I want to replace the default menu icon (3 dots) with another icon.

If the "new icon" is clicked, the side drawer should be opened.

I cant get this to work, and need a bit of help. Thanks in advance.

Answer 1

simply add an item in your menu with showAsAction="always" and set icon of your desire and add following code in onOptionsItemSelected

@Override
    public boolean onOptionsItemSelected(MenuItem item) {

    if(item.getItemId()==R.id.your item id){
    drawer.open();
    }
}
