Question

我知道有很多与此问题相关的问题，但没有一个能解决我的问题。我做了一个有50个问题片段的测验应用程序。在最后一个问题（问题50片段）中，我将得分活动称为显示得分。在此活动中，我创建了一个“再次播放”按钮，再次调用主活动以启动游戏。但每次我点击“再次播放”按钮，我的应用程序都会崩溃。

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);

        }
    });

Answer 1

你是以错误的方式呼唤你的意图。

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

它应该是：

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

虽然这只会让你到页面不再玩游戏。

找不到处理Intent的Activity
