onConfigurationChanged() called when window size changed in Multi-Window Mode

Last post show that onMultiWindowModeChanged() will be called when your app change from Full screen mode to Multi-Window Mode, or reverse. How about size changed in Multi-Window Mode?

This example show that onConfigurationChanged() will be called in case of size changed in Multi-Window Mode.


Modify MainActivity to override onConfigurationChanged() to show a Toast.

package com.blogspot.android_er.androidmultiwindow;

import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

TextView textPrompt;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textPrompt = (TextView)findViewById(R.id.prompt);

if(isInMultiWindowMode()){
textPrompt.setText("onCreate run In Multi Window Mode ");
}else{
textPrompt.setText("onCreate run NOT In Multi Window Mode ");
}

Toast.makeText(MainActivity.this,
"onCreate() called", Toast.LENGTH_LONG).show();
}

@Override
public void onMultiWindowModeChanged(boolean isInMultiWindowMode) {
super.onMultiWindowModeChanged(isInMultiWindowMode);

if(isInMultiWindowMode){
textPrompt.setText("It is In Multi Window Mode ");
}else{
textPrompt.setText("It is NOT In Multi Window Mode ");
}

Toast.makeText(MainActivity.this,
"onMultiWindowModeChanged() called", Toast.LENGTH_LONG).show();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

Toast.makeText(MainActivity.this,
"onConfigurationChanged() called", Toast.LENGTH_LONG).show();
}
}

The layout file keep using that in last post.

The AndroidManifest.xml in this example use the default setting by Android Studio without any changed.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.blogspot.android_er.androidmultiwindow">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>
