package com.example.galleryex02;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.ImageView;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setTitle("电影海报");
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
MyGalleryAdapter galAdapter = new MyGalleryAdapter(this);
gallery.setAdapter(galAdapter);
}
public class MyGalleryAdapter extends BaseAdapter {
Context context;
Integer[] posterID = { R.drawable.mov11, R.drawable.mov12,
R.drawable.mov13, R.drawable.mov14, R.drawable.mov15,
R.drawable.mov16, R.drawable.mov17, R.drawable.mov18,
R.drawable.mov19, R.drawable.mov20 };
public MyGalleryAdapter(Context c) {
context = c;
}
public int getCount() {
// TODO Auto-generated method stub
return posterID.length;
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageview = new ImageView(context);
imageview.setLayoutParams(new Gallery.LayoutParams(100, 150));
//设置image大小
imageview.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageview.setPadding(5, 5, 5, 5);
imageview.setImageResource(posterID[position]);
final int pos = position;
//点击galley的image的时候
imageview.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
ImageView ivPoster = (ImageView) findViewById(R.id.ivPoster);
ivPoster.setScaleType(ImageView.ScaleType.FIT_CENTER);
ivPoster.setImageResource(posterID[pos]);
return false;
}
});
return imageview;
}
}
}
效果如下：
