Keyboard disappears on orientation change

Question

I have a fragment with EditText and add it into the layout using transactions. But if I rotate to landscape the soft keyboard disappears.

public class MainActivity extends AppCompatActivity {

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

        if (getSupportFragmentManager().findFragmentById(R.id.fragmentContainer) == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.fragmentContainer, new FragmentWithEditText())
                    .commit();
        }
    }
}

I want keyboard state still unchanged after rotate using fragment transactions. Because if I don't use transactions, but add a fragment straight in the layout, the keyboard not disappeared.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        android:tag="fragmentWithKeyboard"
        android:name="com.test.FragmentWithEditText"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

I already tried to use android:windowSoftInputMode="stateUnchanged" or android:configChanges="keyboardHidden|orientation", but didn't help.

Also I wrote a sample app with this behavior https://github.com/anton9088/FragmentAndKeyboard

Answer 1

Try to set your EditText's attribute freezesText value to true.

You can also add focus in onViewCreated callback manually

Answer 2

Change below lines in your manifest i am sure it will helps you

<activity
android:name=".YourActivityName"
android:configChanges="orientation|screenSize">
</activity>

So replace your

android:configChanges="keyboardHidden|orientation" To android:configChanges="orientation|screenSize"
