How to Implement Drawerarrowtoggle from Android Appcompat V7 21 Library

How to implement DrawerArrowToggle from Android appcompat v7 21 library

First, you should know now the android.support.v4.app.ActionBarDrawerToggle is deprecated.

You must replace that with android.support.v7.app.ActionBarDrawerToggle.

Here is my example and I use the new Toolbar to replace the ActionBar.

MainActivity.java

public class MainActivity extends ActionBarActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(mToolbar);
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
        this,  mDrawerLayout, mToolbar,
        R.string.navigation_drawer_open, R.string.navigation_drawer_close
    );
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    mDrawerToggle.syncState();
}

styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

You can read the documents on AndroidDocument#DrawerArrowToggle_spinBars

This attribute is the key to implement the menu-to-arrow animation.

public static int DrawerArrowToggle_spinBars


Whether bars should rotate or not during transition

Must be a boolean value, either "true" or "false".

So, you set this: <item name="spinBars">true</item>.

Then the animation can be presented.

Hope this can help you.

You can use ActionBar to change icon with this method.

with this you can set back icon whatever u want.

Android appcompat v7 support library Notification compact view repeating buttons issue

You are using the same NotificationCompat.Builder instance to create your Notifications and whenever you add an Action it is added to the previous List and creates an unwanted behavior into the System Api. You have to call clearActions() first on the Builder before adding any if you want to use the same Builder instance.
