android的ListView图文混搭

Posted 2020-08-23

main4.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
   
     >
    
	
	<ListView 
	    android:id="@+id/listView4_1_1"
	    android:layout_width="match_parent"
	    android:layout_height="wrap_content"
	    ></ListView>
	
	
</LinearLayout>

main4_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center"
    >
	<ImageView 
	    android:id="@+id/imageView4_1_1"
	    android:layout_width="wrap_content"
	    android:layout_height="wrap_content"
	    android:src="@drawable/ic_launcher"
	  
	    />
	<TextView 
	    android:id="@+id/textView4_1_1"
	    android:layout_width="match_parent"
	    android:layout_height="wrap_content"
	    android:text="textView"
	   
	    />
</LinearLayout>

MainActivity4

package com.example.listview;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.R.anim;
import android.R.drawable;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class MainActivity4 extends Activity{
	private ListView listView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main4);
		listView=(ListView) findViewById(R.id.listView4_1_1);
		//一个列表项的内容
		Map<String, Object> map=new HashMap<String, Object>();
		map.put("image", R.drawable.ic_launcher);
		map.put("name", "张三");
		
		
		Map<String, Object> map2=new HashMap<String, Object>();
		map2.put("image", R.drawable.ic_launcher);
		map2.put("name", "王五");
		
		List<Map<String, Object>> list=new ArrayList<Map<String,Object>>();
		list.add(map);
		list.add(map2);
		SimpleAdapter simpleAdapter=new 
				SimpleAdapter(this, list, R.layout.main4_item, 
						new String [] {"image","name"}, 
						new int [] {R.id.imageView4_1_1,R.id.textView4_1_1});
		listView.setAdapter(simpleAdapter);
	}
}

亦可以自定义Adapter

mian5.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    
    >
    
    
    <ListView 
        android:id="@+id/listView5_1_1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        ></ListView>

</LinearLayout>

main5_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center"
    >
	<ImageView 
	    android:id="@+id/imageView5_1_1"
	    android:layout_width="wrap_content"
	    android:layout_height="wrap_content"
	    android:src="@drawable/a"
	  
	    />
	<TextView 
	    android:id="@+id/textView5_1_1"
	    android:layout_width="match_parent"
	    android:layout_height="wrap_content"
	    android:text="textView"
	   
	    />
</LinearLayout>

MainActivity5

package com.example.listview;

import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity5 extends Activity  {
	private ListView listView;
	//定义的数据
	private int [] images={R.drawable.ic_launcher,R.drawable.ic_launcher};
	private String [] names={"xiaobai","xiaoming"};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main5);
		listView=(ListView) findViewById(R.id.listView5_1_1);
		listView.setAdapter(new MyAdapter());
		
		
	}
	//自定义适配器
	class MyAdapter extends BaseAdapter{
		//获取列表项总数
		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return names.length;
		}
		//获取每一个列表项(根据下标获取)
		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return names[position];
		}
		//获取每一个列表项的id
		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return position;
		}
		//
		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			//获取布局填充器
			LayoutInflater layoutInflater=getLayoutInflater();
			//获取main5_item的布局模板
			View view=layoutInflater.inflate(R.layout.main5_item, null);
			//从得到的view查找相应view
			ImageView imageView=(ImageView) view.findViewById(R.id.imageView5_1_1);
			TextView textView=(TextView) view.findViewById(R.id.textView5_1_1);
			imageView.setImageResource(images[position]);
			textView.setText(names[position]);
			return view;
		}
		
	}
}

这种方式会多次调用getView()方法
