activity_main.xml页面：

<?xml version="1.0" encoding="utf-8"?>
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.example.gallery.mainactivity">
 
  <gallery
    android:id="@+id/galpicture"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centervertical="true"
    android:layout_centerhorizontal="true" />
</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;
  }
}

mainactivity.java页面：

package com.example.gallery;
 
import android.support.v7.app.appcompatactivity;
import android.os.bundle;
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();
      }
    });
  }
}
