AndroidApps/ApplicationsMobile Development

This example demonstrates how do I use viewFlipper in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <ViewFlipper
      android:id="@+id/viewFlipper"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:inAnimation="@android:anim/slide_in_left"
      android:outAnimation="@android:anim/slide_out_right">
      <ImageView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:src="@drawable/image"
         android:layout_gravity="center"/>
      <Button
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="Button"
         android:textSize="48sp"
         android:textStyle="bold"
         android:layout_gravity="center"/>
   </ViewFlipper>
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:layout_alignParentStart="true"
      android:layout_margin="16dp"
      android:onClick="previousView"
      android:text="Previous" />
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:layout_alignParentEnd="true"
      android:layout_margin="16dp"
      android:onClick="nextView"
      android:text="Next" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.TextView;
import android.widget.ViewFlipper;
public class MainActivity extends AppCompatActivity {
   private ViewFlipper viewFlipper;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      viewFlipper = findViewById(R.id.viewFlipper);
      TextView textView = new TextView(this);
      textView.setText("Dynamically added TextView");
      textView.setGravity(Gravity.CENTER_HORIZONTAL);
      viewFlipper.addView(textView);
      viewFlipper.setFlipInterval(2000);
      viewFlipper.startFlipping();
   }
   public void previousView(View v) {
      viewFlipper.setInAnimation(this, R.anim.slide_in_right);
      viewFlipper.setOutAnimation(this, R.anim.slide_out_left);
      viewFlipper.showPrevious();
   }
   public void nextView(View v) {
      viewFlipper.setInAnimation(this, android.R.anim.slide_in_left);
      viewFlipper.setOutAnimation(this,
      android.R.anim.slide_out_right);
      viewFlipper.showNext();
   }
}

Step 4 − Create a android Resource Directory(anim) → Right click, create android Resource files (slide_in_right & slide_out_left) and the following codes −

Slide_in_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
   <translate
      android:duration="@android:integer/config_mediumAnimTime"
      android:fromXDelta="50%p"
      android:toXDelta="0" />
   <alpha
      android:duration="@android:integer/config_mediumAnimTime"
      android:fromAlpha="0.0"
      android:toAlpha="1.0" />
</set>

slide_out_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
   <translate
      android:duration="@android:integer/config_mediumAnimTime"
      android:fromXDelta="0"
      android:toXDelta="-50%p" />
   <alpha
      android:duration="@android:integer/config_mediumAnimTime"
      android:fromAlpha="1.0"
      android:toAlpha="0.0" />
</set>

Step 5 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      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>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run Play Icon icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
