package cn.csdn.android.test;
import android.app.Activity;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.LinearLayout;
public class Android_test2Activity extends Activity{
int [] image = new int []{
R.drawable.a,
R.drawable.b,
R.drawable.c,
R.drawable.d,
R.drawable.e
};
int currentImg = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.id.root);
LinearLayout main = (LinearLayout) findViewById(R.id.root);
final ImageView images = new ImageView(this);
main.addView(images);
images.setImageResource(image[0]);
images.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(currentImg>=4){
currentImg=-1;
}
images.setImageResource(image[++currentImg]);
}
});
}
}
