Android(安卓)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>

布局文件如下：

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>

另一个是listview的子view的布局

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);    }@Overridepublic int getCount() {// TODO Auto-generated method stubreturn size;}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn null;}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn 0;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubconvertView = 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;}    }}

运行界面如下
