Introduction

In this page you can find the example usage for android.view View getMeasuredWidth.

Prototype

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:aksha.upcomingdemo.HorizontalListView.java

private void fillListLeft(int leftEdge, final int dx) {
    // Loop adding views to the left until the screen is filled
    while (leftEdge + dx - mDividerWidth > 0 && mLeftViewAdapterIndex >= 1) {
        mLeftViewAdapterIndex--;//from   w  w w. ja v a  2 s . c  o  m
        View child = mAdapter.getView(mLeftViewAdapterIndex, getRecycledView(mLeftViewAdapterIndex), this);
        addAndMeasureChild(child, INSERT_AT_START_OF_LIST);

        // If first view, then no divider to the left of it
        leftEdge -= mLeftViewAdapterIndex == 0 ? child.getMeasuredWidth()
                : mDividerWidth + child.getMeasuredWidth();

        // If on a clean edge then just remove the child, otherwise remove the divider as well
        mDisplayOffset -= leftEdge + dx == 0 ? child.getMeasuredWidth()
                : mDividerWidth + child.getMeasuredWidth();
