android - runOnUiThread 导致应用程序变慢并最终强制关闭

Question

我有 MainActivity(它扩展了 Activity)和 GameView(它扩展了 SurfaceView)。

MainActivity 有用于得分和剩余时间的 TextView。GameView 计算得分和剩余时间，并更新 MainActivity 中的 TextView。

这很有效，但问题是当我一遍又一遍地重新开始游戏时。重新启动的游戏越多，它们变得越慢，最终应用强制关闭。

以下是我在 logcat 消息中看到的内容。

这是我的 XML。

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout>

    <com.example.games.GameView
        android:id="@+id/mGameView"
        ... />

    <TextView
        android:id="@+id/timer"
        ... />

    <TextView
        android:id="@+id/totalScore"
        ... />

    <Button 
        android:id="@+id/submitButton" 
        ... />

   <Button 
        android:id="@+id/resetButton" 
        ... /> 

</RelativeLayout>

这是我的 MainActivity。

public class MainActivity extends Activity {

    /* Variables are declared here */       

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);      

        /* Variables are initialized here */

        mGameView = (GameView) findViewById(R.id.mGameView);

        findViewById(R.id.submitButton).setOnClickListener(buttonListener);
        findViewById(R.id.resetButton).setOnClickListener(buttonListener);

        // TextViews for displaying Score and Timer
        tvScore = (TextView) findViewById(R.id.totalScore);
        tvTimer = (TextView) findViewById(R.id.timer);          
    }   

    @Override
    protected void onDestroy() {
        super.onDestroy();
        /* Garbage collection by unbindDrawables() here */
        System.gc();
    }

    //---------------------------
    // Option menu
    //---------------------------
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        menu.add(1, 1, 0, "New Game");
        menu.add(1, 2, 0, "Quit Game");
        return true;
    }

    //---------------------------
    // onOptions ItemSelected
    //---------------------------
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case 1:
            Intent intentNewGame = new Intent(MainActivity.this,
                                   MainActivity.class);
            MainActivity.this.startActivity(intentNewGame);
            finish();
            break;
        case 2:
            /* Quits game here */
            break;
        }
        return true;
    }

    //---------------------------------------------
    // buttonListener()
    //---------------------------------------------
    private OnClickListener buttonListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            int id = v.getId();
            if (id == R.id.submitButton) {
                mGameView.submit = true;
            } else if (id == R.id.resetButton) {
                mGameView.reset = true;
            }   
        }
    };

    //---------------------------------------------
    // SetTotalScore()
    //---------------------------------------------
    public void SetTotalScore(final int totalScore) {
        final String score = "" + totalScore + " points";
        MainActivity.this.runOnUiThread(new Runnable() {
            public void run() {
                tvScore.setText(score); 
            }
        });
    }

    //---------------------------------------------
    // SetTimer()
    //---------------------------------------------
    public void SetTimer(final String timer, final int time) {
        MainActivity.this.runOnUiThread(new Runnable() {
            public void run() {             
                if (time <= 10) tvTimer.setTextColor(Color.RED);
                tvTimer.setText(timer); 
            }
        });
    }

}

下面是我如何从 GameView 调用 SetTotalScore() 和 SetTimer() 以便用新的分数和剩余时间更新 TextView。

((MainActivity) getContext()).SetTotalScore(totalScore);
((MainActivity) getContext()).SetTimer(timer, timeLeft);

同样，这很有效，但问题是每次我开始新游戏时，它会变得越来越慢，直到它最终强制关闭。

我很确定问题出在这两个 runOnUiThread 上，因为除了这两个使用 runOnUiThread 的 TextView 之外，即使在多次重新启动游戏后，其他所有内容都可以正常显示。

任何处理此问题的好主意将不胜感激!

谢谢!

当您的 Activity 被销毁时，您似乎没有终止后台线程。并且该线程持有对已终止 Activity 的引用。更多 Activity 重启 - 更多线程 - 更多陈旧 Activity 。

检查 DDMS 中的线程数。
