        setContentView(R.layout.aaa);

        image1=(ImageView)findViewById(R.id.image1); 
        image2=(ImageView)findViewById(R.id.image2); 

        image1=(ImageView)findViewById(R.id.image1); 
        image2=(ImageView)findViewById(R.id.image2);

            public void onTick(long millisUntilFinished) { 


                if(a == 0)

I am not sure if I understood the request but i would try something like this:

public class MainActivity extends Activity {
    private ImageView image1,image2;
    int a = 0; 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.aaa);

        image1=(ImageView)findViewById(R.id.image1); 
        image2=(ImageView)findViewById(R.id.image2); 
        image1.setVisibility(View.VISIBLE); 
        image2.setVisibility(View.INVISIBLE); 

        new CountDownTimer(4000, 1000) { 
            public void onTick(long millisUntilFinished) { 
                if(a == 0) { 
                    image1.setVisibility(View.VISIBLE); 
                } else if(a == 1) { 
                    image1.setVisibility(View.INVISIBLE); 
                    image2.setVisibility(View.VISIBLE); 
                }
                a++; 
            } 
            public void onFinish() { 
                Intent i=new Intent(MainActivity.this,NextActivity.class);
                startActivity(i);
            } 
        }.start();
    }
}
