Modify menu/menu_main.xml, to add checkable items:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/item_checkable1"
android:orderInCategory="100"
android:title="Checkable opt 1"
android:checkable="true"
android:checked="true"/>
<item
android:id="@+id/item_checkable2"
android:orderInCategory="100"
android:title="Checkable opt 2"
android:checkable="true"
android:checked="false"/>
<item
android:id="@+id/item_normal"
android:orderInCategory="100"
android:title="Normal item"/>
</menu>
Modify MainActivity.java, modify onOptionsItemSelected() to handle the item click.
package com.blogspot.android_er.androidtoolbar;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Toolbar example");
toolbar.setSubtitle("Android-er.blogspot.com");
toolbar.setLogo(android.R.drawable.ic_menu_info_details);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Toast.makeText(this, item.getTitle(), Toast.LENGTH_LONG).show();
int item_id = item.getItemId();
switch(item_id){
case R.id.item_checkable1:
if(item.isChecked()){
item.setChecked(false);
}else{
item.setChecked(true);
}
break;
case R.id.item_checkable2:
if(item.isChecked()){
item.setChecked(false);
}else{
item.setChecked(true);
}
break;
}
return super.onOptionsItemSelected(item);
}
}
Next:
- Add button inside Toolbar
