Question

我在我的XML文件中创建了ListView，但我想从ListView上的项目中打开一个新屏幕。

我知道我必须使用OnItemClickListener，但我不知道我必须做什么。有人能帮帮我吗？

我在Java中的ListView：

package com.example.listentomusic;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;

public class March extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.march);

        ListView list = (ListView) findViewById(R.id.listView1);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View viewClicked, int position, long id) {
                // TODO Auto-generated method stub
                startActivity(new Intent("android.intent.action.ABOUT"));

            }
        });
    }

}

我在XML中的ListView：

<?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"
    android:orientation="vertical"
    android:background="@drawable/standaard_background" >

     <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/maart"
        android:textSize="30sp"
        android:textColor="#FFFFFF"
        android:background="#000000" />

     <android.support.v7.widget.Space
         android:id="@+id/space1"
         android:layout_width="fill_parent"
         android:layout_height="15dp" />

     <ListView
         android:id="@+id/listView1"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:entries="@array/songs_march"
         android:textColor="#FFFFFF" >
     </ListView>

</LinearLayout>

我的字符串数组：

您需要创建一个适配器，我建议您使用ArrayAdapter

然后使用通过list.setAdapter（）将适配器设置为ListView。之后在onItemClick回调中，您将获得被单击的项目的位置（从0开始）。另见example。
