你可以这样做：

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity {

    int[] drawables = {R.drawable.a,R.drawable.b,R.drawable.c,R.drawable.d,R.drawable.e,R.drawable.f,R.drawable.g};

    Handler   handler;
    int       i         = 0;
    ImageView img;

    public void slide() {

        this.handler = new Handler();
        this.handler.postDelayed( new Runnable() {
            @Override
            public void run() {

                MainActivity.this.img.setImageResource( MainActivity.this.drawables[MainActivity.this.i] );

                if ( MainActivity.this.i < ( MainActivity.this.drawables.length - 1 ) ) {

                    MainActivity.this.i++;
                } else {
                    MainActivity.this.i = 0;
                }

                Toast.makeText( MainActivity.this.getBaseContext(), "Next " + MainActivity.this.i, Toast.LENGTH_SHORT ).show();

                MainActivity.this.slide();
            }
        }, 3000 );
    }

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

        this.img = ( ImageView ) this.findViewById( R.id.image );

        this.slide();

    }

}

布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="200dip"
        android:layout_height="200dip" />

</RelativeLayout>
