Example 11 with Space

use of android.support.v4.widget.Space in project AntennaPod by AntennaPod.

the class CustomMRControllerDialog method onCreateMediaControlView.

@Override
public View onCreateMediaControlView(Bundle savedInstanceState) {
    boolean landscape = getContext().getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;
    if (landscape) {
        /*
             * When a horizontal LinearLayout measures itself, it first measures its children and
             * settles their widths on the first pass, and only then figures out its height, never
             * revisiting the widths measurements.
             * When one has a child view that imposes a certain aspect ratio (such as an ImageView),
             * then its width and height are related to each other, and so if one allows for a large
             * height, then it will request for itself a large width as well. However, on the first
             * child measurement, the LinearLayout imposes a very relaxed height bound, that the
             * child uses to tell the width it wants, a value which the LinearLayout will interpret
             * as final, even though the child will want to change it once a more restrictive height
             * bound is imposed later.
             *
             * Our solution is, given that the heights of the children do not depend on their widths
             * in this case, we first figure out the layout's height and only then perform the
             * usual sequence of measurements.
             *
             * Note: this solution does not take into account any vertical paddings nor children's
             * vertical margins in determining the height, as this View as well as its children are
             * defined in code and no paddings/margins that would influence these computations are
             * introduced.
             *
             * There were no resources online for this type of issue as far as I could gather.
