的Android開始新的活動

我創建一個XML格式的列表，android.And其Java代碼中有延長的活動，而不是擴展列表activity.I中號不能寫代碼來開始新的活動聞一點擊一個特定的row.here是我的代碼...的Android開始新的活動

Java代碼

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

public class Menu extends Activity { 
    String[] values = new String[] { "Android", "iPhone", "WindowsMobile", 
      "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", 
      "Linux", "OS/2" }; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.menu); 

      ArrayAdapter adapter = new ArrayAdapter<String>(this,`` 
       android.R.layout.simple_list_item_1, values); 
      ListView View = (ListView) findViewById(R.id.list); 
      View.setAdapter(adapter); 

    }

XML代碼

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:paddingTop="4dp" 
android:background="@drawable/ic_launcher"> 

<LinearLayout 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" > 

</LinearLayout> 

<ListView 
    android:id="@+id/list" 
    android:layout_width="200dp" 
    android:layout_height="325dp" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentRight="true" 
    android:cacheColorHint="#00000000" 
    android:drawSelectorOnTop="false" > 
</ListView> 

</RelativeLayout>

你想在一個特定的項目，當點擊啓動什麼樣的活動？ – Rob013

哪個部位有問題？在回覆用戶點擊列表中的項目時是否需要幫助？或者你需要幫助開始另一項活動？ –

嘗試是這樣的：

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.menu); 

      ArrayAdapter adapter = new ArrayAdapter<String>(this,`` 
       android.R.layout.simple_list_item_1, values); 
      ListView View = (ListView) findViewById(R.id.list); 
      View.setAdapter(adapter); 
      view.setOnItemClickListener(new OnItemClickListener() { 
       public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { 
        Toast.makeText(getApplicationContext(), "You chose item number: "+position, Toast.LENGTH_LONG).show(); 
       } 
      }); 
    }

您可以撥打list上的setOnItemClickListener並檢查position並啓動相應的Intent。事情是這樣的......

ListView listView = (ListView) findViewById(R.id.list); 
listView.setAdapter(adapter); 
listView.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

     // Check which list item was clicked by checking the 'position' 
     // and start an Activity accordingly 
     switch(position) { 
     case 0: 
      Toast.makeText(getApplicationContext(), "Position: " + position, Toast.LENGTH_SHORT).show(); 
      Intent oneIntent = new Intent(MainActivity.this, OneFragment.class); 
      startActivity(oneIntent); 
      break; 
     case 1: 
      Toast.makeText(getApplicationContext(), "Position: " + position, Toast.LENGTH_SHORT).show(); 
      Intent twoIntent = new Intent(MainActivity.this, TwoFragment.class); 
      startActivity(twoIntent); 
     // AND SO ON... 
     } 
    } 
});

View.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 


     switch(position) { 
     case 0: 

      Intent intnscnd = new Intent(MainActivity.this, secondactivity.class); 
      startActivity(intnscnd); 
      this.finish(); 
      break; 
     case 1: 

      Intent intnthrd = new Intent(MainActivity.this, thirdactivity.class); 
      startActivity(intnthrd); 
      this.finish(); 

     } 
    } 
});
