public final int getMeasuredWidth()

Like #getMeasuredWidthAndState() , but only returns the raw width component (that is the result is masked by #MEASURED_SIZE_MASK ).

Usage

From source file:co.ceryle.segmentedbutton.SegmentedButtonGroup.java

/**
 * Crate a bitmap from the given view//ww  w .  j  ava  2s.  c o m
 */
private Bitmap getViewBitmap(View view) {
    // setContainerAttrs();

    //Get the dimensions of the view so we can re-layout the view at its current size
    //and create a bitmap of the same size
    int width = view.getMeasuredWidth();
    int height = view.getMeasuredHeight();

    int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
    int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY);

    //Cause the view to re-layout
    view.measure(measuredWidth, measuredHeight);
    view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

    //Create a bitmap backed Canvas to draw the view into
    Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);

    //Now that the view is laid out and we have a canvas, ask the view to draw itself into the canvas
    view.draw(c);
    return b;
