Question

当我尝试结束应用程序时，我的自定义SurfaceView类崩溃了。当按下“home”或“back”时，应用程序将结束，但通知我：“'游戏'已经崩溃”

如何正确结束Surfaceview？

提前致谢

这是我的绘图方法：

public void draw(Canvas canvas) {
    super.draw(canvas);
    Paint textPaint = new Paint();
    textPaint.setColor(Color.BLACK);
    textPaint.setTextSize(30);
    canvas.drawColor(Color.WHITE);
    canvas.drawText("mX: " + mx, 10, 30, textPaint);
    canvas.drawText("mY: " + my, 10, 70, textPaint);
    canvas.drawText("calX: " + calibrationX, 10, 110, textPaint);
    canvas.drawText("calY: " + calibrationY, 10, 150, textPaint);

}

几个月前我已经遇到了同样的问题，但我忘了如何正确关闭包含自定义表面视图的活动......
