How to Add Back Button in the Title Bar

METHOD 1

1. First, we need to initialize the toolbar-

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

2. Now, add a call for an up button

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

3. In the ActivityMain.xml add the widget.ToolBar

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

4. In the Manifest.xml you have to add no action bar to the activity so that toolbar can show up.

android:theme="@style/AppTheme.NoActionBar

METHOD 2

In this method, you have to add the parentActivityName in the AndroidManifest.xml

android:parentActivityName=".MainActivity"

This will enable the back button in the title bar. This will only work when there is an action bar enable. If Action bar is hidden then the back button will not appear.
