Answer 1

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 2

You can replace default navigation icon (and button of cause) in following way.

Define usual UI with toolbar in your XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.Toolbar
            android:id="@id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"/>

    </android.support.design.widget.AppBarLayout>

    <!-- Here goes your UI -->

</LinearLayout>

Then setup your Toolbar as ActionBar in onCreate method

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

    Toolbar toolbar = findViewById(R.id.toolbar);

    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); // Make toolbar show navigation button (i.e back button with arrow icon)

    toolbar.setNavigationIcon(R.drawable.custom_icon); // Replace arrow icon with our custom icon
}

Handle back navigation button in onOptionsItemSelected method:

@Override
    public boolean onOptionsItemSelected(MenuItem menuItem) {
        if (menuItem.getItemId() == android.R.id.home) {

            // Do whatever you want

            return true;
        }

        return super.onOptionsItemSelected(menuItem);
    }

The same in Kotlin

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        setSupportActionBar(toolbar)

        supportActionBar?.setDisplayHomeAsUpEnabled(true) // Important step, we enable button on the left side of the toolbar

        toolbar.navigationIcon = getDrawable(R.drawable.custom_icon) // Here we change default navigation button icon

    }

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
        return when (item.itemId) {
            android.R.id.home -> {
                doSomething() // Here we can perform any action
                true
            }
            else -> super.onOptionsItemSelected(item)
        }
    }

    private fun doSomething() {
        Toast.makeText(this, "Hello", Toast.LENGTH_LONG).show()
    }
}

Result:

Answer 3

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

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.

Answer 5

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);

    }
}

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:
