android - Tiled drawable sometimes stretches -


i have listview items have tiled background. accomplish this, use following drawable xml:

<bitmap     xmlns:android="http://schemas.android.com/apk/res/android"     android:src="@drawable/tile"     android:tilemode="repeat" />

usually, works. sometimes, however, src drawable isn't tiled, stretched fill entire list item. (i've got several different tiles this, , use them mixed in 1 listview. if there stretching instead of tiling, it's never been in of them @ once, that's worth.)

i tried add android:dither="true" xml, since read somewhere without there might bugs. didn't change anything.

has had same problem? how did fix it?

i got bitten problem. hard diagnose, harder find similar reports , usable solutions.

"tapas" on freenode #android-dev irc channel came following utility method:

public static void fixbackgroundrepeat(view view) {     drawable bg = view.getbackground();     if (bg != null) {         if (bg instanceof bitmapdrawable) {             bitmapdrawable bmp = (bitmapdrawable) bg;             bmp.mutate(); // make sure aren't sharing state anymore             bmp.settilemodexy(tilemode.repeat, tilemode.repeat);         }     } }

apply views have tiled background set (e.g. findviewbyid them).

also, have impression bug started acting after setting "anydensity=true" in androidmanifest.xml
