created issue #1

Jul 24, 2021 01:22PM

Artifact used: androidx.core:core:1.6.0 Version used: 1.6.0 Theme used: (Not related) Devices/Android versions reproduced on: Pixel 5 Android 11

https://cs.android.com/androidx/platform/frameworks/support/+/c32cc6c885b20be94d2d1c0498e4a978161d3f61:core/core/src/main/java/androidx/core/graphics/TypefaceCompatApi29Impl.java;l=131-136

final FontStyle defaultStyle = new FontStyle(
    (style & Typeface.BOLD) != 0 ? FontStyle.FONT_WEIGHT_BOLD
       : FontStyle.FONT_WEIGHT_NORMAL,
    (style & Typeface.ITALIC) != 0 ? FontStyle.FONT_SLANT_ITALIC
       : FontStyle.FONT_SLANT_UPRIGHT
);

return new Typeface.CustomFallbackBuilder(familyBuilder.build())
    .setStyle(defaultStyle)
    .build();

This part will make the final Typeface lost the correct font-weight from the FontInfo. For example, request for a font with 500 weight, but the final Typeface has 400 weight. This will make the fallback font incorrectly displayed.

The fix is to use the style from the best-matched font, just like the platform, https://cs.android.com/android/platform/superproject/+/android-11.0.0_r1:frameworks/base/graphics/java/android/graphics/Typeface.java;l=276-285.

Trying to reproduce this on my 4.2.2 (v17) Nexus 4. Added this drawable:

<transition xmlns:android="

http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/test_drawable_blue"/>
<item android:drawable="@drawable/test_drawable_green"/>
</transition>

where blue/green drawables look like this:

<shape
xmlns:android="

http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size
android:width="@dimen/drawable_large_size"
android:height="@dimen/drawable_small_size" />
<solid
android:color="@color/test_blue" />
</shape>

Then added this test:

@Test
public void testMutateTransitionDrawable() {
Drawable drawable = ResourcesCompat.getDrawable(mResources,
R.drawable.test_transition_drawable, null);
assertTrue(drawable instanceof TransitionDrawable);

Drawable mutated = drawable.mutate();
assertTrue(drawable instanceof TransitionDrawable);
assertTrue(mutated instanceof TransitionDrawable);
}

It passes on the device. Going to also try on other earlier devices a bit later in the day once they are charged.

Also not reproducible on Galaxy Nexus running 4.0.1 (v14), 4.0.4 (v15) and 4.2.2 (v17)

https://android-review.googlesource.com/c/platform/frameworks/support/+/960032 with the test. Closing as not reproducible. If this is still happening for you, we'd need to see either a test (same as in this CL) or a small, standalone sample project that reproduces this issue on v17 (or other) devices.
