Add button inside Toolbar

Advertisemen
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>

MainActivity.java
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.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

Button toolBarBtn;

@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);

toolBarBtn = (Button)findViewById(R.id.toolbarbtn);
toolBarBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
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);
}

@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);
}
}
