AlertDialog分段

Question

我在AlertDialog工作中遇到了一些困難。我有六個按鈕，當每個按鈕被點擊時，AlertDialog框應顯示其內容。即使prg運行時沒有任何錯誤，並且如果我點擊一個按鈕對話框不打開任何人都可以幫我解決tat片段頁打開的按鈕？提前致謝。

這裏是我的片段活動代碼：

@TargetApi(Build.VERSION_CODES.HONEYCOMB) 
public class Fragment3 extends DialogFragment implements OnClickListener { 

    private static final int ALERT_DIALOG1 = 1; 
    private static final int ALERT_DIALOG2 = 2; 
    private static final int ALERT_DIALOG3 = 3; 
    private static final int ALERT_DIALOG4 = 4; 
    private static final int ALERT_DIALOG5 = 5; 



    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     //setContentView(R.layout.activity_fragment2); 
    View view = inflater.inflate(R.layout.fragment3layout, container, false); 

     Button alert1 = (Button) view.findViewById(R.id.Button1); 
     alert1.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View view) { 
      showDialog(ALERT_DIALOG1); 
     } 
    }); 



default: 
     dialog = null; 
    } 
    return dialog; 

} 

這裏是我的清單文件

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.pacificstereoapp" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="16" /> 


      </intent-filter> 
     </activity> 
     <activity 
      android:name="com.example.a.Fragment1" 
      android:label="@string/title_activity_fragment1" > 
     </activity> 

    </application> 

</manifest>

你正在創建對話框，但沒有真正顯示它。致電dialog.show()。
