针对异常java.lang.IllegalStateException onMeasure() did not set the measured dimension by calling setMeasuredDimension()的解决办法：

versionName = 2.5.2 versionCode = 20002100
java.lang.IllegalStateException onMeasure() did not set the measured dimension by calling setMeasuredDimension()
View.java 17945

解决办法：
增加setMeasuredDimension调用
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (mNonDecorWindowSizeChangedListener != null) {
mNonDecorWindowSizeChangedListener.onNonDecorWindowSizeChanged(
MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.getSize(heightMeasureSpec),
CameraCommonUtil.getDisplayRotation(getContext()));
}
setMeasuredDimension(widthMeasureSpec, heightMeasureSpec);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
