Step 1 - Create A Empty Projects

Step 2 -  Add Images in drawable folder Which You Want To Include In Your App For Switch One Image To Another Image (Two or More Image)

Step 3 Add This Xml Code In Your Xml Activity Or Fragment

<ImageSwitcher
    android:id="@+id/simpleImageSwitcher"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="50dp" />


<Button
    android:id="@+id/buttonNext"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="150dp"
    android:layout_gravity="center"
    android:background="#050"
    android:textColor="#fff"
    android:textStyle="bold"
    android:text="NEXT" />

 

Step 4 -  Add Java Code In Your Java Code Activity

private ImageSwitcher simpleImageSwitcher;

Button btnNext;



// Array of Image IDs to Show In ImageSwitcher

int imageIds[] = {R.drawable.image1, R.drawable.images2, R.drawable.image3, R.drawable.images4, R.drawable.images5};

int count = imageIds.length;

// to keep current Index of ImageID array

int currentIndex = -1;

 

// get The references of Button and ImageSwitcher

btnNext = (Button) findViewById(R.id.buttonNext);

simpleImageSwitcher = (ImageSwitcher) findViewById(R.id.simpleImageSwitcher);

// Set the ViewFactory of the ImageSwitcher that will create ImageView object when asked

simpleImageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {



    public View makeView() {

        // TODO Auto-generated method stub



        // Create a new ImageView and set it's properties

        ImageView imageView = new ImageView(getApplicationContext());

        // set Scale type of ImageView to Fit Center

        imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);

        // set the Height And Width of ImageView To FIll PARENT

        imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));

        return imageView;

    }

});



// Declare in and out animations and load them using AnimationUtils class

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

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



// set the animation type to ImageSwitcher

simpleImageSwitcher.setInAnimation(in);

simpleImageSwitcher.setOutAnimation(out);





// ClickListener for NEXT button

// When clicked on Button ImageSwitcher will switch between Images

// The current Image will go OUT and next Image  will come in with specified animation

btnNext.setOnClickListener(new View.OnClickListener() {



    public void onClick(View v) {

        // TODO Auto-generated method stub

        currentIndex++;

        //  Check If index reaches maximum then reset it

        if (currentIndex == count)

            currentIndex = 0;

        simpleImageSwitcher.setImageResource(imageIds[currentIndex]); // set the image in ImageSwitcher

    }

});
