这几天学会了ListView组件，希望能帮到你们。

 

 

 

 

程序测试图如下：

 

 

 

 

 

 

 

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>();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//建立数据源initweibos();//创建Adapterlvweibo = (ListView) findViewById(R.id.lv);weiboAdapter adapter=new weiboAdapter(this, R.layout.kankan_item,weibolist);lvweibo.setAdapter(adapter);lvweibo.setOnItemClickListener(new OnItemClickListener() {@Overridepublic 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); }}

 

2.代码如下：

weibo.java

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@Overridepublic 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

<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>
