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

Usage

From source file:cn.ieclipse.af.view.ScrollLayout.java

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    if (debug) {//  ww w . ja  v a  2s .co m
        Log.v(TAG, String.format("onLayout changed=%b,l=%d,t=%d,r=%d,b=%d", changed, l, t, r, b));
    }
    if (changed) {
        int childLeft = 0;
        final int childCount = getChildCount();

        for (int i = 0; i < childCount; i++) {
            final View childView = getChildAt(i);
            if (childView.getVisibility() != View.GONE) {
                final int childWidth = childView.getMeasuredWidth();
                childView.layout(childLeft, 0, childLeft + childWidth, childView.getMeasuredHeight());
                childLeft += childWidth;
            }
