Android，強制關閉單擊對話框按鈕

我想從對話框中啓動另一個活動，但是如果我在模擬器中運行，則會收到此強制關閉。如何解決這個問題？Android，強制關閉單擊對話框按鈕

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    boolean firstrun= true; 
    if (firstrun) { 
     AlertDialog.Builder builder = new AlertDialog.Builder(this).setTitle("This is First Run !").setMessage("Welcome! Please enter the emergency numbers!"); 
     builder.setPositiveButton("OK!", new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int which) { 
       // TODO Auto-generated method stub 
       Intent sv = new Intent(getApplicationContext(),com.sach.droidclinic.Save.class); 
       startActivity(sv); 
      } 
     }); 

     AlertDialog dialogue = builder.create(); 
     dialogue.show(); 
    }

此日誌貓我有問題一起連接，

嘗試這種方式

替換此在點擊

Intent sv = new Intent(getApplicationContext(),com.sach.droidclinic.Save.class); 
       startActivity(sv);

與

Intent sv = new Intent(YourActivityName.this,com.sach.droidclinic.Save.class); 
       startActivity(sv);

謝謝你的幫助，但是我試過了，還是我有同樣的問題，我的應用就是這樣，我有一個2500milisec的啓動畫面，然後出現對話框（雖然這個畫面會導致主要活動），但我需要從對話框的正面按鈕調用另一個活動。 – Sach106

發佈您的mainfest.xml –

試試這個：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    boolean firstrun= true; 
    if (firstrun) { 
     AlertDialog.Builder builder = new AlertDialog.Builder(this).setTitle("This is First Run !").setMessage("Welcome! Please enter the emergency numbers!"); 
     AlertDialog dialogue = builder.create(); 
     dialogue.show(); 
     builder.setPositiveButton("OK!", new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int which) { 
       // TODO Auto-generated method stub 
       Intent sv = new Intent(getApplicationContext(),com.sach.droidclinic.Save.class); 
       startActivity(sv); 
      } 
     }); 


    }

謝謝你的幫助，但是上面的代碼不會在對話框中顯示任何動作按鈕 – Sach106

堆棧跟蹤顯示一個activityNotFoundException。再次查看你的清單文件，並確保你聲明活動com.sach.droidclinic.Save那裏。
