Listview使用安卓自带布局实现单选

安卓提供了一些自带的布局，使用非常简单。直接看代码吧。

package com.example.linfeng.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class ListViewActivity extends Activity {

    private String[] data = { "Apple", "Banana", "Orange", "Watermelon",
            "Pear", "Grape", "Pineapple", "Strawberry", "Cherry", "Mango" };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_list_view);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(ListViewActivity.this,  android.R.layout.simple_list_item_single_choice , data);
        ListView listView = (ListView) findViewById(R.id.lv1);
        listView.setAdapter(adapter);
    }
}

然后是布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.linfeng.myapplication.ListViewActivity">

    <!-- android:choiceMode ="singleChoice"实现单选的关键-->
    <ListView
        android:id="@+id/lv1"
        android:choiceMode ="singleChoice"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </ListView>
</LinearLayout>
