Add button inside Toolbar

This example modify from my old post “Implement checkable items in OptionsMenu of Toolbar” to add button to Toolbar.

Edit activity_main.xml to add Button inside android.support.v7.widget.Toolbar:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="com.blogspot.android_er.androidtoolbar.MainActivity">

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="#FFA000">
<Button
android:id="@+id/toolbarbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_gravity="right"/>

</android.support.v7.widget.Toolbar>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>

toolBarBtn.setOnClickListener(new View.OnClickListener() {

Toast.makeText(getBaseContext(),
"Button in ToolBar clicked",
Toast.LENGTH_LONG).show();
}

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);

return super.onOptionsItemSelected(item);
}
