</RelativeLayout>

GalleryAdapter.java页面：

package com.example.gallery;
 
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.ImageView;
 
public class GalleryAdapter extends BaseAdapter {
 private Context mContext;
 
 int[] images = {R.mipmap.apple, R.mipmap.banana, R.mipmap.bicycle, R.mipmap.chair,R.mipmap.chopsticks, R.mipmap.dog, R.mipmap.fish, R.mipmap.pear}; //本地图片
 
 public GalleryAdapter (Context context) {
  this.mContext = context;
 }
 
 @Override
 public int getCount() {
  return images.length;
 }
 
 @Override
 public Object getItem(int i) {
  return i;
 }
 
 @Override
 public long getItemId(int i) {
  return i;
 }
 
 @Override
 public View getView(int i, View view, ViewGroup viewGroup) {
  ImageView image = new ImageView(mContext);
  image.setImageResource(images[i]); //设置图片
  image.setAdjustViewBounds(true); //是否调整边框
  image.setLayoutParams(new Gallery.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
  return image;
 }
}

import android.view.View;
import android.widget.AdapterView;
import android.widget.Gallery;
import android.widget.Toast;
 
public class MainActivity extends AppCompatActivity {
 GalleryAdapter galleryAdapter;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  Gallery galPicture = findViewById(R.id.galPicture);
  galleryAdapter = new GalleryAdapter(MainActivity.this);
  galPicture.setAdapter(galleryAdapter);
  //相应的点击事件
  galPicture.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    Toast.makeText(MainActivity.this, "图片" + i, Toast.LENGTH_LONG).show();
   }
  });
 }
}
