Example of Android ImageSwitcher Widget

At first, we will create android application. Then, we will use imageSwitcher widget in this application.

1. Creating New Project

Follow steps below to create new project. Please ignore the steps if you have already created a new application.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as ImageSwitcher. Then, click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. If you have followed above process correctly, you will get a newly created project successfully. However, you can also visit post to create a new project to know steps in detail.

Now, we will modify xml and java file to use imageSwitcher widget in the application.

2. Modify Values folder

Open res/values/strings.xml file. Then, add below code into it.

<resources>
	<string name="app_name">ImageSwitcher</string>
	<string name="next">Next</string>
</resources>

3. Use ImageSwitcher Widget in xml file

Open res/layout/activity_main.xml file. Then, add below code into it.

<?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="match_parent"
	android:orientation="vertical">

	<Button
		android:id="@+id/button"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content"
		android:layout_gravity="center"
		android:layout_marginTop="40dp"
		android:text="@string/next"/>

	<ImageSwitcher
		android:id="@+id/imageSwitcher"
		android:layout_width="320dp"
		android:layout_height="320dp"
		android:layout_gravity="center"/>

</LinearLayout>

In activity_main.xml file, we have defined button and imageSwitcher widgets in xml file. Now, we will access these widgets in java file and perform some actions on them.

4. Access ImageSwitcher Widget in java file

Open src/main/java/com.tutorialwing.imageswitcher/MainActivity.java file. Then, add below code into it.

package com.tutorialwing.imageswitcher;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageSwitcher;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ViewSwitcher;

public class MainActivity extends AppCompatActivity {

	int[] nameList = {R.drawable.chinchilla,
			R.drawable.cod,
			R.drawable.crane,
			R.drawable.crocodile,
			R.drawable.deer,
			R.drawable.dog,
			R.drawable.dolphin,
			R.drawable.dove,
			R.drawable.eel,
			R.drawable.elephant,
			R.drawable.emu,
			R.drawable.fly
	};

	private int index = 0;

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

		final ImageSwitcher imageSwitcher = findViewById(R.id.imageSwitcher);
		if (imageSwitcher != null) {
			imageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
				public View makeView() {
					ImageView imageView = new ImageView(getApplicationContext());
					imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
					imageView.setLayoutParams(new
							ImageSwitcher.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
							LinearLayout.LayoutParams.WRAP_CONTENT));

					return imageView;
				}
			});

			imageSwitcher.setImageResource(nameList[index]);

			Animation in = AnimationUtils.loadAnimation(this, android.R.anim.slide_in_left);
			imageSwitcher.setInAnimation(in);

			Animation out = AnimationUtils.loadAnimation(this, android.R.anim.slide_out_right);
			imageSwitcher.setOutAnimation(out);
		}

		Button button = findViewById(R.id.button);
		if (button != null) {
			button.setOnClickListener(new View.OnClickListener() {
				@Override
				public void onClick(View v) {
					index = (++index < nameList.length) ? index : 0;
					if (imageSwitcher != null) {
						imageSwitcher.setImageResource(nameList[index]);
					}
				}
			});
		}
	}
}

At first, you need to store some images in res/drawable folder. However, you can click here to download drawables used in this project.

In MainActivity.java file, we have accessed imageSwitcher and button widgets. Then, we have set factory for imageSwitcher. This is used to created views between imageSwitcher will flip. Here, we are creating imageViews and setting it’s parameters. After that, we have set default image using imageResource method. After that, we have set animations for images when they start appearing/disappearing on/from the screen. At last, we have set a click listener on button to show next image in the imageSwitcher. Note that first image will be shown if we are currently at last image and next button is clicked.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml

Code inside src/main/AndroidManifest.xml file is as below –

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

	<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>

When we run the program, we will get output as shown above.

That’s end of tutorial on Android ImageSwitcher widget.
