使用setMeasure方法是无效的
setMeasuredDimension(width, height);
如果想设置,可以用LayoutParams
ConstraintLayout.LayoutParams layoutParams = (ConstraintLayout.LayoutParams) getLayoutParams();
layoutParams.width = (int) mPaint.measureText("Do you like waht you see?");
setLayoutParams(layoutParams);
现在想是蠢了点,setMeasure是用来测量控件大小的,肯定是没用的
