I have a style
<style name="MyText">
<item name="android:background">#ffc0c0c0</item>
<item name="android:textColor">#ffff8080</item>
</style>
which I am trying to introspect in my ocde. I use this code to retrieve
typed array:
final Resources.Theme theme = getActivity().getTheme();
final int[] attrs = {android.R.attr.textColor, android.R.attr.background,};
final TypedArray a = theme.obtainStyledAttributes(null, attrs, 0,
R.style.MyText);
try {
Log.d(TAG, "length: " + a.length());
for (int i = 0; i < a.length(); ++i) {
final TypedValue v = a.peekValue(i);
if (v != null) {
Log.d(TAG, "type: " + v.type);
}
Log.d(TAG, "---------------------------------");
}
} finally {
a.recycle();
}
The output is:
D/PlaceholderFragment( 3391): length: 2
D/PlaceholderFragment( 3391): type: 28
D/PlaceholderFragment( 3391): ---------------------------------
D/PlaceholderFragment( 3391): type: 28
D/PlaceholderFragment( 3391): ---------------------------------
Everything seems fine at this point. But when I change the order of the
attribute in the array from
final int[] attrs = {android.R.attr.textColor, android.R.attr.background,};
to
final int[] attrs = {android.R.attr.background, android.R.attr.textColor,};
the output becomes
D/PlaceholderFragment( 3528): length: 2
D/PlaceholderFragment( 3528): type: 28
D/PlaceholderFragment( 3528): ---------------------------------
D/PlaceholderFragment( 3528): ---------------------------------
The second TypedValue returned by the peekValue() method becomes null in
the second case. Why? What am I doing wrong?
Thank you!
