    }

Answer 1

Recommended way

getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_settings_24dp);// set drawable icon
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

Handle icon click event

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case android.R.id.home:
            Toast.makeText(this, "click..!!", Toast.LENGTH_SHORT).show();
            return true;
        default:
            return super.onOptionsItemSelected(item);

    }
}

Answer 2

I always like to put a AppBarLayout that I can control the way the toolbar appears

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbarAddPlan"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:layout_marginLeft="50dp"
            app:popupTheme="@style/AppTheme.PopupOverlay" >

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

            <ImageButton
                android:id="@+id/btnAddPlanTourClose"
                style="@style/Widget.AppCompat.Button.Borderless"
                android:layout_width="45dp"
                android:layout_height="45dp"
                android:layout_alignParentLeft="true"
                android:layout_alignParentStart="true"
                android:layout_centerVertical="true"
                android:src="@drawable/close_circle_outline" />
        </RelativeLayout>
</android.support.design.widget.AppBarLayout>

That way a can put more elements and arrange them like I want. In this case insert a left icon to close the activity by a fragment.

So in the fragment a do this

 //That is in the Fragment
setupToolbar(R.id.toolbarAddPlan,getString(R.string.addPlanTour),true)





//It is in na Kotlin Extansion file.



 inline fun Fragment.setupToolbar(@IdRes id: Int, title:String?= null, upNavigation: Boolean = false) : ActionBar {

    val activityCompat = activity as AppCompatActivity
    val toolbar = activity?.findViewById<Toolbar>(id)
    activityCompat.setSupportActionBar(toolbar)
    if(title != null){
        activityCompat.supportActionBar?.title = title
    }
    activityCompat.supportActionBar?.setHomeButtonEnabled(true)
    return activityCompat.supportActionBar!!
}

The result will be something like this:

The action "SALVAR" i put via inflat menu

 override fun onCreateOptionsMenu(menu: Menu?, inflater: MenuInflater?) {
        super.onCreateOptionsMenu(menu, inflater)
        inflater?.inflate(R.menu.menu_add_plan_tour,menu)
    }

    override fun onOptionsItemSelected(item: MenuItem?): Boolean {
        return when (item?.itemId){
            R.id.menuPlanTourSave ->{
                true
            }else ->return super.onOptionsItemSelected(item)
        }

    }

Menu XML layout src/menu/menu_add_plan_tour.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">
    <!-- "Mark Favorite", should appear as action button if possible -->
    <item
        android:id="@+id/menuPlanTourSave"
        android:title="@string/btnSave"
        android:tooltipText="@string/btnSave"
        android:contentDescription="@string/btnSave"
        app:showAsAction="always|withText">
        <TextView
            android:text="@string/btnSave"
            android:textSize="15dp"
            android:textColor="@color/colorPrimaryLight"
            />


    </item>
</menu>

And do not forget to use setHasOptionsMenu(true) to enable the menu.

You can show an icon at the left side using the following code.

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_HOME | 
ActionBar.DISPLAY_SHOW_TITLE | ActionBar.DISPLAY_HOME_AS_UP | ActionBar.DISPLAY_USE_LOGO);
actionBar.setIcon(R.drawable.ic_launcher);

But it wont be clickable. To make a clickable icon at the left, you need to use Toolbar instead of an action bar.

Answer 4

As this is updated era of Android, You must go for Toolbar so that you can do any kind of customization with the help of xml. Instead of using menu i would suggest to use toolbar

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="#ffffa302"
    android:minHeight="@android:dimen/notification_large_icon_height">

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageButton"
        android:layout_gravity="left"
        android:drawable="@drawable/pinterest_pin"
        android:clickable="true"/>

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

And through code you can handle event

Answer 5

You can do the following:

1- create your file_name.xml then Add Toolbar.

2- add RelativeLayout inside the Toolbar's tag.

3- add your views i.e.(ImageButton,TextView,...)

Note: The TextView you are adding is the title of Toolbar.

Sample Code: file_name.xml

<android.support.v7.widget.Toolbar
        android:id="@+id/products_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimaryDark"
        app:layout_collapseMode="pin"
        app:titleTextColor="@android:color/white">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <TextView
                android:id="@+id/toolbar_title"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:text="Title"
                android:gravity="center"
                android:textColor="@android:color/white"
                android:textSize="20dp"
                android:textStyle="bold"
                android:layout_alignParentStart="true"/>

            <ImageButton
                android:id="@+id/toolbar_button"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:src="@drawable/ic_icon_24dp"
                style="@style/Widget.AppCompat.Button.Borderless"
                android:layout_alignParentEnd="true"/>

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

Output:

Answer 6

One thing is that by default title and app icon set into the left and other than icons sent into the right side. If you want to add your icons into the left side there is a way to them into to left side which is:

step 1. create a custom layout which having search, setting icon and your title as you want.

step 2. create a toolBar layout like:

<android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:titleTextColor="#ffffff"
                android:background="#ECA539"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

step 3. inflate your custom layout into the toolbar like:

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

}
private void initToolBar() {
setSupportActionBar(toolbar);
    View customlayout= getLayoutInflater().inflate(R.layout.custom_layout, null);
    toolbar.addView(logo);
}
