java - 带顶部 View 的自定义 ServiceView 在 6.5 分钟后导致应用程序/手机崩溃

Question

我正在使用自定义 SurfaceView 编写一个小游戏。我想将 AdMob View 放在 SurfaceView 的底部，但在运行应用程序大约六分钟后，应用程序抛出错误，然后重新启动手机。我已经用单个按钮替换了 AdMob View ，但错误仍然发生，因此我假设问题是由于将任何 View 放在 SurfaceView 上而引起的。如果我从 SurfaceView 顶部删除任何 View ，游戏就会无限期地正常运行。

我尝试过使用RelativeLayout以外的布局，但问题仍然存在。我想知道是否有人以前遇到过这个问题，或者有任何其他途径可以探索。

自定义 SurfaceView:

public class AndroidFastRenderView extends SurfaceView implements Runnable
{
    private static final String TAG = "AndroidFastRenderView";
    AndroidGame game;
    Bitmap framebuffer;
    Thread renderThread = null;
    SurfaceHolder holder;
    volatile boolean running = false;

    public AndroidFastRenderView(AndroidGame game, Bitmap framebuffer)
    {
        super(game);
        this.game = game;
        this.framebuffer = framebuffer;
        this.holder = getHolder();
    }

    public AndroidFastRenderView(Context context)
    {
        super(context);
    }

    public void resume()
    {
        running = true;
        renderThread = new Thread(this);
        renderThread.start();
    }

    public void run()
    {
        Rect dstRect = new Rect(0,0,80,120);
        long startTime = System.nanoTime();
        while (running)
        {
            if(!holder.getSurface().isValid())
            {
                continue;
            }

            float deltaTime = (System.nanoTime() - startTime) / 1000000000.0f;
            startTime = System.nanoTime();

            game.getCurrentScreen().update(deltaTime);
            game.getCurrentScreen().present(deltaTime);

            Canvas canvas = null;

            canvas = holder.lockCanvas();

            if (canvas != null)
            {
                dstRect = canvas.getClipBounds();
                canvas.drawBitmap(framebuffer, null, dstRect, null);
                holder.unlockCanvasAndPost(canvas);
            }
        }
    }

    public void pause()
    {
        Log.e(TAG, "Paused");
        running = false;
        while(true)
        {
            try {
                renderThread.join();
                break;
            } catch (InterruptedException e) {
                // retry
            }
        }
    }

}

在主要 Activity 中构建界面:

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    boolean isLandscape = getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;

    int frameBufferWidth = isLandscape ? 120 : 80;
    int frameBufferHeight = isLandscape ? 80 : 120;

    Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth, frameBufferHeight, Config.RGB_565);

    float scaleX = (float) frameBufferWidth / getWindowManager().getDefaultDisplay().getWidth();
    float scaleY = (float) frameBufferHeight / getWindowManager().getDefaultDisplay().getHeight();

    renderView  = new AndroidFastRenderView(this, frameBuffer);
    graphics    = new AndroidGraphics(getAssets(), frameBuffer);
    fileIO      = new AndroidFileIO(getAssets());
    audio       = new AndroidAudio(this);
    input       = new AndroidInput(this, renderView, scaleX, scaleY);
    screen      = this.getStartScreen();

    PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
    wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "GLGame");

    if (useAds)
    {
        //adView = new AdView(this, AdSize.SMART_BANNER, AD_UNIT_ID);

        LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

        //adView.setLayoutParams(params);

        RelativeLayout layout = new RelativeLayout(this);
        layout.addView(renderView);
        //layout.addView(adView);

        Button button = new Button(this);
        button.setLayoutParams(params);
        button.setText("Blargle");
        layout.addView(button);

        //adView.loadAd(new AdRequest());

        setContentView(layout);

    }
    else
    {
        setContentView(renderView);
    }
}

错误的LogCat:

此错误会重复出现，直到手机重新启动为止。

通过专门将 renderRiew 设置为 ABOVE AdView 来尝试避免在 SurfaceView 上显示 AdView:

params.addRule(RelativeLayout.ABOVE, renderView.getId());

如果 renderView 没有 ID，您可能需要为其提供一个 ID。
