I want to know a view's size before hand. I measure its size this way.
public static int[] measureSize(ViewGroup parent, int layoutId)
{
View view = LayoutInflater.from(parent.getContext()).inflate(layoutId, parent, false);
final int spec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
view.measure(spec, spec);
final int width = view.getMeasuredWidth(); // ? 0, not include compound drawable size and relative padding. WHY
final int height = view.getMeasuredHeight();
return new int[]{width, height};
}
This is the layout file:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableStart="?android:listChoiceIndicatorSingle"
android:drawablePadding="20dp"/>
The question: the measured view width does always not include the compound drawable size and its related padding. If I don't set text, the measured width is always 0. If set a not empty value, the width is only for the text only. Why? How can I get the correct size?
Thanks in advance.
