私のonToucheventは、クリックした描画可能なシェイプを正しく認識します。 そして、xとyのパラメータも設定できます。 しかし、onTouchEventの最後では、私はinvalidate（）を呼び出しますが、onDrawメソッドは呼び出されません。カスタムrelativeLayoutで描画可能なシェイプを移動
これはなぜですか？
public class DrawView extends RelativeLayout {
private ArrayList<Rectangle> rectangles = new ArrayList<Rectangle>();
private int rectId = 0;
private int width;
private int height;
public DrawView(Context context) {
super(context);
this.setLayoutParams(new RelativeLayout.LayoutParams(width, height));
Rectangle rect1 = new Rectangle(this.getContext());
rect1.setId(1);
rectangles.add(rect1);
this.addView(rect1);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(0, 10, 0, 0);
Rectangle rect2 = new Rectangle(this.getContext());
rect2.setId(2);
params.addRule(RelativeLayout.BELOW, rect1.getId());
rect2.setLayoutParams(params);
rectangles.add(rect2);
this.addView(rect2);
}
