Android 学习--ListView 的使用(三)

使用SimpleAdapter 创建ListView

程序清单1

<?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:layout_width="fill_parent"         android:layout_height="wrap_content"         android:id="@+id/mylist"         /> </LinearLayout>

程序清单2

package xiaocool.net.classspace.ClassBlog; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.widget.ListView; import android.widget.SimpleAdapter; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import xiaocool.net.classspace.R; /**  * Created by MRYU on 2015/3/14.  */ public class TuiJian extends ActionBarActivity {     private ListView listView;     private String[] contents=new String[]{"大声吼孩子有什么用？","大声吼孩子有什么用？","大声吼孩子有什么用？"};     private String[] times=new String[]{"2015/3/14 14:44","2015/3/14 14:44","2015/3/14 14:44"};     private int[] p_w_picpaths=new int[]{R.drawable.touxiang,R.drawable.touxiang,R.drawable.touxiang};     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.classblog_tuijian);         //创建一个List集合 ，list集合的元素是Map         List<Map<String,Object>> listitems=new ArrayList<Map<String, Object>>();         for(int i=0;i<contents.length;i++){             Map<String,Object> listitem=new HashMap<String,Object>();             listitem.put("content",contents[i]);             listitem.put("time",times[i]);             listitem.put("p_w_picpath",p_w_picpaths[i]);             listitems.add(listitem);         }         //创建一个SimpleAdapter         SimpleAdapter simpleAdapter =new SimpleAdapter(this,listitems,R.layout.tuijian_item,                 new String[]{"content","time","p_w_picpath"},                 new int[]{R.id.textContent,R.id.textTime,R.id.p_w_picpathView3}                 );         listView=(ListView)this.findViewById(R.id.mylist);         listView.setAdapter(simpleAdapter);     } }

程序清单3 每一个列表项可根据自己需要进行定制

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent" android:layout_height="match_parent"     android:orientation="horizontal"     >     <TextView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="New Text"         android:id="@+id/textContent"         android:textSize="20sp"         android:layout_marginLeft="55dp"         android:layout_marginStart="55dp"         android:layout_alignParentLeft="true"         android:layout_alignParentStart="true" />     <TextView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="New Text"         android:id="@+id/textTime"         android:textSize="15sp"         android:layout_alignBottom="@+id/p_w_picpathView3"         android:layout_alignLeft="@+id/textContent"         android:layout_alignStart="@+id/textContent" />     <ImageView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/p_w_picpathView3"         android:src="@drawable/touxiang"         android:layout_alignParentTop="true"         android:layout_alignParentRight="true"         android:layout_alignParentEnd="true"         android:layout_marginRight="50dp"         android:layout_marginEnd="50dp" />     <TextView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="New Text"         android:id="@+id/textZan"         android:layout_alignBottom="@+id/p_w_picpathView3"         android:layout_toRightOf="@+id/textContent"         android:layout_toEndOf="@+id/textContent" /> </RelativeLayout>
