检测屏幕触摸是否正常，代码十分简单，亲测有效 super(context, attrs, defStyleAttr); unSelectRect = new ArrayList<>(); selectRect = new ArrayList<>(); //获取屏幕的宽高 DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics(); screenHeight = displayMetrics.heightPixels; screenWidth = displayMetrics.widthPixels; Log.e(TAG, " 屏幕尺寸：" + screenWidth + "x" + screenHeight); paint = new Paint(); paint.setColor(Color.RED); paint.setStyle(Paint.Style.STROKE); // 抗锯齿 paint.setAntiAlias(true); // 防抖动 paint.setDither(true); paint2 = new Paint(); paint2.setColor(Color.GREEN); paint2.setStyle(Paint.Style.FILL); // 抗锯齿 paint2.setAntiAlias(true); // 防抖动 paint2.setDither(true);
