What do you have so far, and where are you stuck making progress? There are numerous libraries out there that display image slideshows; I'm sure they allow you to vary the time between transitions.

public class MainActivity extends AppCompatActivity {
    Button btn1,btn3,btn5,btn10;
    ImageView imageView;
    int b[] = {R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d};
    int z = 0;
    int nImageDelaySeconds=3;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn1 = (Button)findViewById(R.id.button1);
        btn3 = (Button)findViewById(R.id.button3);
        btn5 = (Button)findViewById(R.id.button5);
        btn10 = (Button)findViewById(R.id.button10);
        imageView = (ImageView) findViewById(R.id.imageView);
        imageView.setImageResource(b[0]);
        btn1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                nImageDelaySeconds=1;
            }
        });
        btn3.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                nImageDelaySeconds=3;
            }
        });
        btn5.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                nImageDelaySeconds=5;
            }
        });
        btn10.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                nImageDelaySeconds=10;
            }
        });
        Thread timer = new Thread() {
            public void run() {
                try {
                    sleep(2000);

                    for (z = 0; z < b.length + 4; z++) {
                        if (z < b.length) {
                            sleep(nImageDelaySeconds*1000);
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    imageView.setImageResource(b[z]);
                                }
                            });
                        } else {
                            z = 0;
                        }
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                    System.out.println("finally");
                }
            }
        };
        timer.start();
    }

Set up a Timer to run a TimerTask every 3 seconds. The TimerTask only has to call the button's setText method to change the button's text. You would have to do this within the UI thread, so you should use post to run a Runnable object that will perform the update an the correct thread.
you can try this:-
AnimationDrawable animation = new AnimationDrawable();
   animation.addFrame(getResources().getDrawable(R.drawable.image1), 100);
   animation.addFrame(getResources().getDrawable(R.drawable.image2), 500);
   animation.addFrame(getResources().getDrawable(R.drawable.image3), 300);
   animation.setOneShot(false);

   ImageView imageAnim =  (ImageView) findViewById(R.id.img);
   imageAnim.setBackgroundDrawable(animation);

   // start the animation!
   animation.start()
