Creating a button in Android Toolbar
ToolBar with Button Tutorial
1 - Add library compatibility inside build.gradle
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
2 - Create a file name color.xml
to define the Toolbar
colors
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="ColorPrimary">#FF5722</color>
<color name="ColorPrimaryDark">#E64A19</color>
</resources>
3 - Modify your style.xml
file
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/ColorPrimary</item>
<item name="colorPrimaryDark">@color/ColorPrimaryDark</item>
<!-- Customize your theme here. -->
</style>
</resources>
4 - Create a xml file like tool_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:elevation="4dp" />
5 - Include the Toolbar
into your main_activity.xml
<RelativeLayout 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"
tools:context=".MainActivity">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar" />
<TextView
android:layout_below="@+id/tool_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/TextDimTop"
android:text="@string/hello_world" />
</RelativeLayout>
6 - Then, put it inside your MainActivity
class
package com.example.hp1.materialtoolbar;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Toast;
/* When using AppCompat support library
* (you need to extend Main Activity to
* ActionBarActivity)
* ActionBarActivity has deprecated, use AppCompatActivity
*/
public class MainActivity extends ActionBarActivity {
// Declaring the Toolbar Object
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// Attaching the layout to the toolbar object
toolbar = (Toolbar) findViewById(R.id.tool_bar);
// Setting toolbar as the ActionBar with setSupportActionBar() call
setSupportActionBar(toolbar);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
7 - And finally, add your "Button Items" to the menu_main.xml
inside of /res/menu/
directory
<?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"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/action_settings"
app:showAsAction="never" />
<item
android:id="@+id/action_search"
android:orderInCategory="200"
android:title="Search"
android:icon="@drawable/ic_search"
app:showAsAction="ifRoom"/>
<item
android:id="@+id/action_user"
android:orderInCategory="300"
android:title="User"
android:icon="@drawable/ic_user"
app:showAsAction="ifRoom" />
</menu>
Toolbar customization can done by following ways
write button and textViews code inside toolbar as shown below
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<Button
android:layout_width="wrap_content"
android:layout_height="@dimen/btn_height_small"
android:text="Departure"
android:layout_gravity="right"
/>
</android.support.v7.widget.Toolbar>
Other way is to use item menu as shown below
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
