Add button in android action bar

问题:

I trying to add a button beside HealthyApp, but no luck .

This is my initial code and image

  final ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);

I want to add a delete button beside HealthyApp but the HealthyApp title gone.

 final ActionBar actionBar = getSupportActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setDisplayShowHomeEnabled(false);
        actionBar.setDisplayShowTitleEnabled(false);
        LayoutInflater mInflater = LayoutInflater.from(this);
        View mCustomView = mInflater.inflate(R.layout.header_button, null);
        Button mTitleTextView = (Button) mCustomView.findViewById(R.id.title_text);
        mTitleTextView.setText("Delete");
        actionBar.setCustomView(mCustomView);
        actionBar.setDisplayShowCustomEnabled(true);

Add toolbar inside your xml . and use NoActionBar in your activity theme .

add these toolbar in your xml on top

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#131313"
    android:minHeight="?attr/actionBarSize">

    <LinearLayout
        android:layout_width="wrap_content"
        android:background="#00aaaaaa"
        android:layout_gravity="right"
        android:layout_height="match_parent">

        <Button
            android:text="Delete"
            android:layout_width="wrap_content"
            android:background="#000"
            android:textColor="#fff"
            android:layout_height="wrap_content"
            android:textSize="16dp" />

    </LinearLayout>

</android.support.v7.widget.Toolbar>

add these theme in your activity in Menifest.xml

android:theme="@style/Theme.AppCompat.Light.NoActionBar"

and add these code in your activity ....

Toolbar topToolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(topToolBar);
ActionBar actionBar = getSupportActionBar();;
actionBar.setDisplayHomeAsUpEnabled(true);

Output:-

OR

I think it is possible with the icon only .....

use this item in menu.xml

<?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/delete"
        android:icon="@drawable/YourImage"
        app:showAsAction="always"></item>
</menu>

Note:- use android:icon="@drawable/YourImageWithTextDelete" put here your image .....

In your Activity layout

<android.support.v7.widget.Toolbar
        android:layout_width="match_parent"
        android:background="@color/YourColor"
        android:layout_height="?attr/actionBarSize"
        app:layout_collapseMode="pin"
        android:theme="@style/about_toolbar"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/YourText"
             />
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/YourText"
        />

    </android.support.v7.widget.Toolbar>

In your Activity

public class YourActivity extends ActionBarActivity {

    private Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_acticity_layout);

        // Set a Toolbar to replace the ActionBar.
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitle("");
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

       }

       // ... your other methods
}

In your Manifest, Activity tag

<activity
        android:name=".YourActivity"
        android:label="@string/YourActivityString"
        android:theme="@style/YourTheme" />

In your style.xml

<style name="YourTheme" parent="Theme.AppCompat.Light.NoActionBar">
   <item name="colorPrimary">...</item> <!-- declare your styles -->
</style>

If you need a better code sample: Just download https://github.com/chrisbanes/cheesesquare , It has the example toolbar.
