Question

我已经解决了这个问题一个星期了，我知道它的东西太傻了。当我在手机或模拟器上运行我的应用时，正在绘制的位图重叠。对不起我的语法和我的问题，但这里的代码和模拟器的屏幕截图。

//How I am rendering / drawing the bitmaps
public void render() {

    if (gameHolder.getSurface().isValid()) {
        gameCanvas = gameHolder.lockCanvas();
        gameCanvas.drawColor(Color.BLACK);

        int w = gameCanvas.getWidth();
        int h = gameCanvas.getHeight();

        Log.i("measure", w + " | " + h);

        gameCanvas.drawBitmap(loadInBitmaps(1), (w / 2), h / 2, gamePaint);
        gameCanvas.drawBitmap(loadInBitmaps(2), (w / 2) + 32, h / 2, gamePaint);

        gameHolder.unlockCanvasAndPost(gameCanvas);
    }
}


//How I am loading in the bitmaps
public Bitmap loadInBitmaps(int number) {

    Bitmap loadedBitmap = null;

    if (number == 0) loadedBitmap = null;
    //UI Bitmaps
    if (number == 1)
        loadedBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.northbutton);
    if (number == 2)
        loadedBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.southbutton);

    return loadedBitmap;
}

因为您将drawables放在默认的 drawable 目录中，所以Android假定您的Bitmap需要从默认的mdpi大小缩放。如果要禁用资源缩放，请将您的drawable放在 drawable-nodpi 中。

将位图绘制到Canvas重叠
