set app icon to right side in activity tool bar

Question

I am working with the 'AppCompact' library and faced some problems with layout/positioning. I want to position the App icon on the right hand side of the 'ActionBar'. One method is to define a button in the toolbar, but is there a standard method to set the App icon and Up button on the right hand side of the ActionBar?

As you can see in the above image, the icon is positioned on the left, I want it to be on the right. Any help would be appreciated.

P.s:For people who may face my problem it can be fixed easily using this code Add this code to manifest:

<application android:supportsRtl="true">

and then write this code on Oncreate:

getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);

There is no way android provides to set app icon at right side of actionbar but you can still do that.

Create a menu, say main_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/menu_item"
        android:icon="@drawable/your_app_icon"
        android:title="@string/menu_item"
        app:showAsAction="always"/>  //set showAsAction always
                                    //and this should be the only menu item with show as action always

</menu>

Now just override onCreateOptionsMenu in your activity class.

add this in MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu){

    getMenuInflater().inflate(R.menu.main_menu, menu);
    return super.onCreateOptionsMenu(menu);
}

It's done! Your app icon will be visible on right side of ActionBar now.

If you have more than one item in menu then override onPrepareOptionsMenu in activity class and set setEnabled(false) for menu item having app icon, doing this prevents your icon to be clickable.

@Override
public boolean onPrepareOptionsMenu(Menu menu){
    menu.findItem(R.id.menu_item).setEnabled(false);

    return super.onPrepareOptionsMenu(menu);
}

Now your MainActivity.java file would look like

@Override
public boolean onCreateOptionsMenu(Menu menu){

    getMenuInflater().inflate(R.menu.main_menu, menu);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item){

    switch(item.getItemId()){
        case R.id.menu_item:   //this item has your app icon
            return true;

        case R.id.menu_item2:  //other menu items if you have any
            //add any action here
            return true;

        case ... //do for all other menu items

        default: return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onPrepareOptionsMenu(Menu menu){
    menu.findItem(R.id.menu_item).setEnabled(false);

    return super.onPrepareOptionsMenu(menu);
}

This is the only trick you can use to set app icon on right side.
