找不到處理Intent的活動

Question

我知道這個問題有很多問題，但是他們都沒有解決我的問題。我做了一個包含50個問題片段的測驗應用程序。在最後一個問題（問題50片段）中，我將分數活動稱爲顯示分數。在此活動中，我創建了一個「再次播放」按鈕，該按鈕再次調用主要活動來開始遊戲。但每次我點擊「再次播放」按鈕，我的應用程序崩潰。

logcat的錯誤：04-03 15:34:43.638 26316-26316/com.example.moresche.englishqigame E/AndroidRuntime: FATAL EXCEPTION: main android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.example.moresche.englishqigame.MainActivity }

scoreActivity.java

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_score); 

    Typeface mTypeface = Typeface.createFromAsset(getAssets(),"chlo.TTF"); 
    TextView myTextview = (TextView)findViewById(R.id.txtla); 
    myTextview.setTypeface(mTypeface); 

    Typeface m2Typeface = Typeface.createFromAsset(getAssets(),"chlo.TTF"); 
    TextView m2yTextview = (TextView)findViewById(R.id.txtla1); 
    m2yTextview.setTypeface(m2Typeface); 
    initControls(); 



} 




public void initControls() { 

    TextView final_score = (TextView) findViewById(R.id.textView103); 
    TextView final_scoreqi = (TextView) findViewById(R.id.textView104); 
    TextView lvlqi = (TextView) findViewById(R.id.textViewzzz); 
    Button btnxd = (Button)findViewById(R.id.btnx); 


    final SharedPreferences app_preferences = PreferenceManager.getDefaultSharedPreferences(this); 

    ... 

    btnxd.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      app_preferences.edit().clear().commit(); 
      Intent intent1 = new Intent ("com.example.moresche.englishqigame.MainActivity"); 
      startActivity(intent1); 

     } 
    }); 

清單文件：

要調用錯誤的方式你的意圖。

Intent intent1 = new Intent ("com.example.moresche.englishqigame.MainActivity"); 

它應該是沿着線的東西：

Intent intent1 = new Intent(scoreActivity.this,MainActivity.class);

雖然只會考慮你的頁面不再玩遊戲。
