我正在尝试为 android 制作 TicTacToe 游戏。但我有以下问题。首先，我想为我的应用程序实现线程，但我没有成功（几乎尝试过任何东西）。其次，我想知道如何处理这两个错误（我不知道它们是否被称为错误）：将堆（碎片情况）增加到 65.24 MB 以进行 2567824 字节分配 ，跳过 118 帧！该应用程序可能在其主线程上做了太多工作（尽管我认为这可以通过线程实现来解决）

public class DrawClass extends View {

int index;
int x, y, RectX, RectY;
// it will hold the rectangles dimensions depending on the screen dimensions
public Rect[] rectangles = new Rect[9];
// it will be our reference array as to what does each rectangle hold
char[] isFilledWith = { ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ' };
// bitmaps
Bitmap empty, cross, circle;

// constructor
public DrawClass(Context context) {

    super(context);
    // setting bitmaps and calculating screen dimensions
    setBitmaps();
    Calculations(context);

}

public void setBitmaps() {// set the 3 bitmaps empty , circle , cross
    cross = BitmapFactory.decodeResource(getResources(), R.drawable.cross1);
    circle = BitmapFactory.decodeResource(getResources(),
            R.drawable.circle1);
    empty = BitmapFactory.decodeResource(getResources(), R.drawable.empty1);
}

@Override
public void onDraw(Canvas canvas) {

    super.onDraw(canvas);

    Paint paint = new Paint();
    // this for updates the canvas with the appropriate bitmaps cross , circle or empty 
    // depending on tyhe char array isFilledWith
    for (int i = 0; i < 9; i++) {
        if (isFilledWith[i] == ' ') {
            canvas.drawBitmap(empty, null, rectangles[i], null);

Skipped 118 frames ! The applcation may be doing too much work on its main thread你在 UI 线程上做了很多工作。创建线程或使用 asynctask 来完成繁重的工作将解决此错误。看看这个http://www.vogella.com/articles/AndroidBackgroundProcessing/article.html，它解释得很好。

为了帮助您解决线程和异步任务的难题，您必须更加具体，但要找到性能问题所在，您可以使用 Android 的分析工具。
