Android学习第三天--listview方式一

第一种listview

xml文件中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:id="@+id/listview1"
        android:entries="@array/info"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

在res下的values下添加下面的文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="info">
        <item>test1</item>
        <item>test1</item>
        <item>test1</item>
            <item>test1</item>
        <item>test1</item>
        <item>test1</item>
            <item>test1</item>
        <item>ltest1n</item>
        <item>test1</item>
            <item>test1</item>
        <item>test1</item>
        <item>test1</item>
    </string-array>    
</resources>

 

主java文件中

 

package cn.core.test;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity {

    ListView listView =null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        listView=(ListView)findViewById(R.id.listview1);
        
        
        listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) {
                
                System.out.println(arg0.getItemAtPosition(position).toString());
            }
        });
        
    }


}
