Android 实现微信聊天一样的布局

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:orientation="vertical"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      >      <TextView android:id="@+id/text"       android:paddingTop="10dip"       android:textColor="#FFA07A"       android:background="@drawable/bg_normal"       android:layout_width="wrap_content"       android:layout_height="wrap_content"/>  </LinearLayout>

一个是主程序布局：

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:orientation="vertical"      android:layout_width="fill_parent"      android:layout_height="fill_parent"      android:paddingTop="10dip"      android:paddingLeft="30dip"      android:paddingRight="30dip"      >      <ListView android:id="@+id/listview"      android:layout_width="fill_parent"      android:layout_height="fill_parent"      android:clickable="false"      android:scrollbars="none">      </ListView>  </LinearLayout>

主程序代码如下：

package com.cloay;    import android.app.Activity;  import android.content.Context;  import android.os.Bundle;  import android.view.LayoutInflater;  import android.view.View;  import android.view.ViewGroup;  import android.widget.BaseAdapter;  import android.widget.ListView;  import android.widget.TextView;  /**   *    * MyListTestActivity.java   * @author cloay   * 2011-10-18   */  public class TestActivity extends Activity {      /** Called when the activity is first created. */   private ListView listView = null;      @Override      public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);          initView();      }     private void initView() {    listView = (ListView)findViewById(R.id.listview);          listView.setDividerHeight(0);          ListAdapter adapter = new ListAdapter(this, 5);          listView.setAdapter(adapter);   }            public class ListAdapter extends BaseAdapter {       private LayoutInflater inflater;       private int size;       public ListAdapter(Context context, int size){        this.size = size;        inflater = LayoutInflater.from(context);       }    @Override    public int getCount() {     // TODO Auto-generated method stub     return 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) {     // TODO Auto-generated method stub     convertView = inflater.inflate(R.layout.list, null);     TextView text = (TextView) convertView.findViewById(R.id.text);     text.setText(position + ":This is a test !dasgagaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaafdfffffdffg");     convertView.setEnabled(false);     return convertView;    }      }  }
