What is unit of parameter value in onMeasure(int widthMeasureSpec, int heightMeasureSpec) method of View Class?

Question

Can Any body let me know what is the unit of parameter of onMeasure(int widthMeasureSpec, int heightMeasureSpec) this View Class Method.

I print the log it return me 1073742144,-2147483251 respectively.

Answer 1

The value is a combination of mode and size. Use View.MeasureSpec.getMode(widthMeasureSpec) to get the mode (one of MeasureSpec.EXACTLY, MeasureSpec.AT_MOST and MeasureSpec.UNSPECIFIED); what you probably want to know is View.MeasureSpec.getSize(widthMeasureSpec), the size in pixels.
