Android 用の TicTacToe ゲームを作成しようとしています。しかし、私は次の問題があります。何よりもまず、アプリにスレッドを実装したいのですが、成功していません (ほとんど何でも試しました)。次に、これらの 2 つのエラーに対処する方法を知りたいです (エラーと呼ばれるかどうかはわかりませ ん) 。アプリケーションがメイン スレッドで処理しすぎている可能性があります(ただし、これはスレッドの実装で解決されると思います)。

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);

}

Skipped 118 frames ! The applcation may be doing too much work on its main threadUIスレッドで多くの作業を行っています。スレッドを作成するか、asynctask を使用して重い作業を行うと、このエラーは解決します。このhttp://www.vogella.com/articles/AndroidBackgroundProcessing/article.htmlを見てください。よく説明されています。
