Android GridView，Gallery动态更新数据

 

 

package com.android.wei.zidingyi.adapter;

import android.app.Activity;

import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Gallery;
import android.widget.GridView;

import java.util.*;


public class MyActivity extends Activity {
	  
	    private Gallery gallery;
	    private GridView gridView;
	    private ImageAdapter listViewAdapter;
	    public static  ImageAdapterView imageAdapterView;
	    private List<Map<String,Object>> listItems;
	    private Integer[] imgeIDs = {
	    	R.drawable.niao,R.drawable.niao,R.drawable.rui,R.drawable.rui,
	    	R.drawable.ning,R.drawable.ning
	    };
	    private String[] goodsNames={
	    	"土豆丝","土豆块","土豆泥","红烧土豆",
	    	"麻辣土豆","清蒸土豆"
	    };
	    private String[] goodsDetails={
	    	"土豆丝：便宜又好吃",	"土豆丝：便宜又好吃",	"土豆丝：便宜又好吃",	
	    	"土豆丝：便宜又好吃",	"土豆丝：便宜又好吃",	"土豆丝：便宜又好吃",
	    };
	    private int[] money={
	    	2,3,3,10,8,13	
	    };
	   
	    public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        /**全屏显示**/
	        requestWindowFeature(Window.FEATURE_NO_TITLE);
	        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
	          WindowManager.LayoutParams.FLAG_FULLSCREEN);
	        
	        setContentView(R.layout.main);
	        gridView=(GridView) this.findViewById(R.id.gridView1);
	        imageAdapterView = new ImageAdapterView(this);
	        gridView.setAdapter(imageAdapterView);
	        gallery = (Gallery) this.findViewById(R.id.gallery1);
	        listItems = getListItems();
	        listViewAdapter = new ImageAdapter(this,listItems);
	        gallery.setAdapter(listViewAdapter);
	       
	    }

	    	
	  
	    private List<Map<String,Object>> getListItems(){
	    	List<Map<String,Object>> listItems = new ArrayList<Map<String,Object>>();
	    	for(int i=0;i<goodsNames.length;i++){
	    		Map<String,Object> map = new HashMap<String,Object>();
	    		map.put("image", imgeIDs[i]);
	    		map.put("title", goodsNames[i]);
	    		map.put("info", money[i]+"元");
	    		
	    		listItems.add(map);
	    	}
	    	return listItems;
	    }

}

 然后是Gallery的

 

package com.android.wei.zidingyi.adapter;

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

import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import java.util.*;






public class ImageAdapter extends BaseAdapter{
    private Context context;
   
    
    private List<Map<String,Object>> listItems;
    
    private LayoutInflater listContainer;
    
    private boolean[] hasChecked;
    public final class ListItemView{
    	public ImageView image;
    	public TextView title;
    	public TextView info;
    	
    
    	public Button add;
    }
    
    public ImageAdapter(Context context,List<Map<String,Object>> listItems){
    	this.context = context;
    	listContainer = LayoutInflater.from(context);
    	this.listItems = listItems;
    	hasChecked = new boolean[getCount()];
    }
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return listItems.size();
	}

	@Override
	public Object getItem(int position) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return 0;
	}
	
	
	

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
	    final int  selectId = position;
		ListItemView listItemView = null;
		if(convertView ==null){
			listItemView = new ListItemView();
			convertView = listContainer.inflate(R.layout.list_item, null);
			//获得控件对象
			listItemView.image =(ImageView) convertView.findViewById(R.id.imageitem);
			listItemView.title =(TextView) convertView.findViewById(R.id.textview);
			listItemView.info =(TextView) convertView.findViewById(R.id.textview1);
			listItemView.add =(Button) convertView.findViewById(R.id.button1);
			
		   //设置空间集到convertView
			convertView.setTag(listItemView);
		}else{
			listItemView = (ListItemView) convertView.getTag();
		}
		//设置文字图片
		listItemView.image.setBackgroundResource((Integer)listItems.get(position).get("image"));
		listItemView.title.setText((String)listItems.get(position).get("title"));
		listItemView.info.setText((String) listItems.get(position).get("info"));
        listItemView.add.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				Map<String,Object> map = new HashMap<String,Object>();
	    		map.put("image", listItems.get(selectId).get("image"));
	    	
	    		ImageAdapterView.menuList.add(map);
		       MyActivity.imageAdapterView.notifyDataSetChanged();
			}
		});
		
		
		return convertView;
	}

}

 最后GridView的

 

package com.android.wei.zidingyi.adapter;

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

import java.util.*;

public class ImageAdapterView extends BaseAdapter{
	private Context context;
	
	private LayoutInflater layoutInflater;
	
    public static List<Map<String,Object>> menuList = new ArrayList<Map<String,Object>>();
	
    public static class ItemListView{
    	public ImageButton image;
    }
    public ImageAdapterView(Context context){
		this.context = context;
		layoutInflater = LayoutInflater.from(context);
		
	}
	public int getCount() {
		// TODO Auto-generated method stub
		return menuList.size();
	}

	@Override
	public Object getItem(int position) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return 0;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ItemListView itemListView = null;
		if(convertView==null){
			itemListView = new ItemListView();
			convertView = layoutInflater.inflate(R.layout.item_list1, null);
			
			itemListView.image=(ImageButton) convertView.findViewById(R.id.menuImage);
			convertView.setTag(itemListView);
		}else {
			itemListView=(ItemListView)convertView.getTag();
		}
	   itemListView.image.setBackgroundResource((Integer)menuList.get(position).get("image"));
	   itemListView.image.setOnClickListener(new View.OnClickListener() {
		
		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			Toast.makeText(context, "触发成功", Toast.LENGTH_SHORT).show();
		}
	});
		return convertView;
	}

}
