1.代码如下:

 

 

 

MainActivity.java

 

 

package com.example.weibokankan;

import java.util.ArrayList;
import java.util.List;

import com.example.weibokankan.weiboAdapter;
import com.example.weibokankan.MainActivity;
import com.example.weibokankan.R;
import com.example.weibokankan.weibo;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity {
	private ListView lvweibo;
    private List<weibo> weibolist=new ArrayList<weibo>();
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
//		建立数据源
		initweibos();
//		创建Adapter
		lvweibo = (ListView) findViewById(R.id.lv);
		weiboAdapter adapter=new weiboAdapter(this, R.layout.kankan_item,weibolist);
		lvweibo.setAdapter(adapter);
		lvweibo.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> adapterView, View view, int position,
					long id) {
				// TODO Auto-generated method stub
				 weibo wb=	weibolist.get(position);
				    Toast.makeText(MainActivity.this, wb.getName(), Toast.LENGTH_SHORT).show();
			}
		});
	}
    
 private void initweibos(){
	weibo webo1=new weibo("潇湘夜雨",R.drawable.p1,"人的一生中会有很多理想。短的叫念头,长的叫志向,坏的叫野心,好的叫愿望。理想就是希望,希望是生命的原动力!");
	weibolist.add(webo1);
	weibo webo2=new weibo("皮皮小皮",R.drawable.p2,"一座城市的包容力就体现在,不仅容纳了你这样的怂货,更接纳了欺负你的坏人。");
	weibolist.add(webo2);
	weibo webo3=new weibo("失心症",R.drawable.p3,"人总是害怕改变,因为改变会带来一份陌生。活在过去的人没有勇气面对陌生——-但人生只有一个方向,就是向前走,就是踏入未来。在陌生里才有新的机会,大步朝前吧。");
	weibolist.add(webo3);
	weibo webo4=new weibo("夏末",R.drawable.p4,"总盯着你了不起的过去,你就不会有了不起的未来。");
	weibolist.add(webo4);
	weibo webo5=new weibo("我在幸福后面",R.drawable.p5,"一朵花的凋零,荒芜不了整个春天,一次挫折也荒废不了整个人生。");
	weibolist.add(webo5);
	weibo webo6=new weibo("等",R.drawable.p6,"挫折是一块石头,对于弱者来说它是拌脚石,让你停步不前。而对于强者来说它是垫脚石,使你站得更高。");
	weibolist.add(webo6);
	weibo webo7=new weibo("夜雨潇湘",R.drawable.p7,"所有杀不死你的,都会使你强大。");
	weibolist.add(webo7);
	weibo webo8=new weibo("潇湘夜雨",R.drawable.p8,"人生途中,有些是无法逃避的,比如命运;有些是无法更改的,比如情缘;有些是难以磨灭的,比如记忆;有些是难以搁置的,比如爱恋,与其被动地承受,不如勇敢地面对!");
	weibolist.add(webo8);
	weibo webo9=new weibo("浅笑如昔",R.drawable.p9,"啦啦啦啦啦啦啦啦啦,德玛西亚!!!!!!");
	weibolist.add(webo9);
	weibo webo10=new weibo("娃娃脸",R.drawable.p10,"啦啦啦啦啦啦啦啦啦,德玛西亚!!!!!!");
	weibolist.add(webo10);
 }

只听到从架构师办公室传来架构君的声音:
花光浓烂柳轻明,酌酒花前送我行。有谁来对上联或下联?

 

2.代码如下:

weibo.java

此代码由Java架构师必看网-架构君整理
package com.example.weibokankan; public class weibo { private String name; private int imageId; private String say; public weibo(String name, int imageId, String say) { super(); this.name = name; this.imageId = imageId; this.say=say; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getImageId() { return imageId; } public void setImageId(int imageId) { this.imageId = imageId; } public String getSay() { return say; } public void setSay(String say) { this.say = say; } }

3.代码如下:

weiboAdapter.java

package com.example.weibokankan;

import java.util.List;

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

import com.example.weibokankan.R;
import com.example.weibokankan.weibo;

public class weiboAdapter extends ArrayAdapter<weibo> {
	private int resourceId;
	public weiboAdapter(Context context, int textViewResourceId,
			List<weibo> data) {
		super(context, textViewResourceId, data);
		resourceId=textViewResourceId;
	}

	// 这个方法在每个子项被滚动到屏幕内的时候会被调用
	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		weibo wb = getItem(position);
		View view=LayoutInflater.from(getContext()).inflate(resourceId, null);
		ImageView ivFruit=(ImageView) view.findViewById(R.id.ivimage);
		TextView tvweibo=(TextView) view.findViewById(R.id.tv);
		TextView tvweibosay=(TextView) view.findViewById(R.id.tvsay);
		ivFruit.setImageResource(wb.getImageId());
		tvweibo.setText(wb.getName());
		tvweibosay.setText(wb.getSay());
		return view;
	}





	

}

 

4.代码如下:

activity_main.xml

此代码由Java架构师必看网-架构君整理
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/LinearLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <ListView android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="wrap_content" > </ListView> </LinearLayout>

 

5.代码如下:

kankan_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" >
   <ImageView
        android:id="@+id/ivimage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:src="@drawable/p1" />
   <RelativeLayout
    android:id="@+id/rl" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    
    >
    <TextView
        android:id="@+id/tv"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        
        android:text="Apple" /> 

     <TextView
         android:id="@+id/tvsay"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:layout_below="@id/tv"
         android:layout_alignLeft="@id/tv"
         android:text="1fdggwhvgtrryvbxcvffrigoiggkgfijijkmkvmgiovmgiomkom iogm" />

    </RelativeLayout>
</LinearLayout>
