Gallery画廊,SlidingDrawer侧滑

Gallery控件用于灵活展示图片)过期

java:

package com.example.gallerytext;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Gallery;
import android.widget.Toast;

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


        
    }

xml里面写Gallery属性

继承BaseAdapter适配器

package com.example.gallerytext;

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;
    //设置要展示的图片资源
    int[] images = {R.drawable.ic_launcher,R.drawable.f1,R.drawable.f2,R.drawable.f3,R.drawable.f4,R.drawable.f5,R.drawable.f6,R.drawable.f7,R.drawable.f8,R.drawable.f9,R.drawable.f10,};

    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) {
        //在此最好判断一下view是否为空
        ImageView image = new ImageView(mContext);
        image.setImageResource(images[i]);
        image.setAdjustViewBounds(true);
        //设置宽高
        image.setLayoutParams(new Gallery.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        return image;
    }
}

安卓中1.5后加入了SlidingDrawer【隐藏式抽屉】，设计原理在你的UI布局有限的情况下，放不下太多的控件的时候，可以考虑用这个隐藏式抽屉。用SlidingDrawer注意两点，一个是android：handle（委托要展开的图片加载Layout配置） 和android：content（要展开的Layout Content）:

主java里打

package com.example.slid;

import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.SlidingDrawer;
  
public class MainActivity extends Activity {  
  
    private GridView gridView;  
    private SlidingDrawer slidingDrawer;  
    private ImageView imageView;  
    private int[] icons={  
        R.drawable.widget01, R.drawable.widget02,  
        R.drawable.widget03, R.drawable.widget04,  
        R.drawable.widget05, R.drawable.widget06,
        R.drawable.widget07, R.drawable.widget08,
        R.drawable.widget09,
    };  
      
    private String[] items={"家园卫士","安装包","游戏盒子",
   "链接电脑","记事本","垃圾箱","流量管理","软件修复","系统设置"
    };  
      
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        gridView = (GridView)findViewById(R.id.mycontent);  
        slidingDrawer = (SlidingDrawer)findViewById(R.id.sliding_drawer);//初始化  
        imageView = (ImageView)findViewById(R.id.my_image);//拉菜单的小箭头  
        MyGridViewAdapter adapter = new MyGridViewAdapter(this, items, icons);//继承了BaseAdapter基础适配器  
        gridView.setAdapter(adapter);//设置适配  
        slidingDrawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {  
            //设置打开抽屉的监听
            public void onDrawerOpened() {  
                //设置小箭头的方向
                imageView.setImageResource(R.drawable.right1);  
            }  
        });  
        slidingDrawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {  
              //设置关闭抽屉监听
            public void onDrawerClosed() {  
                imageView.setImageResource(R.drawable.left1);  
            }  
        });  
    }  
  
   
}

基础适配器

package com.example.slid;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class MyGridViewAdapter extends BaseAdapter{  
  
    private Context context;  
    private String[] items;  
    private int[] icons;  
      
    public MyGridViewAdapter(Context context, String[] items, int[] icons){  
        this.context = context;  
        this.items = items;  
        this.icons = icons;  
    }  
      
    public int getCount() {  
        return items.length;  
    }  
  
    public Object getItem(int arg0) {  
        return items[arg0];  
    }  
  
    public long getItemId(int position) {  
        return position;  
    }  
  
    public View getView(int position, View convertView, ViewGroup parent) {  
        Shuju shuju=null;
        if(convertView==null){
            LayoutInflater layoutInflater = LayoutInflater.from(context);  
            convertView = (View)layoutInflater .inflate(R.layout.wode, null);
            shuju=new Shuju();
            shuju.imageView = (ImageView)convertView.findViewById(R.id.image_view);  
            shuju.textview = (TextView)convertView.findViewById(R.id.text_view);
            convertView.setTag(shuju);
        }else{
            shuju= (Shuju) convertView.getTag();
        }
        //第二种加载布局方式
        shuju.imageView.setImageResource(icons[position]);  
        shuju.textview.setText(items[position]);  
        return convertView;  
    }  
 class Shuju{
     TextView textview;
     ImageView imageView;
    }
  
}
