Done.

+package org.chromium.ui.autofill;

+import android.graphics.Canvas;
+import android.graphics.ColorFilter;

+import android.graphics.RectF;

mDividerRect always has integer coordinates, so I'd use Rect instead of RectF

Done.

can you add comment or perhaps use a constant for this?

[keishi, 2013/11/07 04:19:18]

I found a constant already defined android.graphics.PixelFormat.OPAQUE

+    }
