如何從列表視圖中打開新屏幕

Question

我在我的XML文件中創建了ListView，但我想從我的ListView上的項目打開一個新屏幕。

我知道我必須使用OnItemClickListener但我不知道我必須做什麼。 有人可以幫我嗎？

我ListView在Java中：

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ListView在XML：

<?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> 

我的字符串數組：

<string-array name="songs_march">

你需要創建一個適配器，你的情況我推薦使用ArrayAdapter

然後，使用將適配器設置爲ListView，通過list.setAdapter（）。 在onItemClick回調之後，您將獲得被點擊的項目的位置（從0開始）。 另請參閱example。
