Thank you to everyone who tried to help. You helped me reach the final answer, but no one solution was quite right. @user3137702 was probably the closest, as it IS related to the whole move to vectors/SVGs. I couldn’t find a definitive answer, like something directly from Google (although I imagine it is out there), … Read more
For me, setting the gravity of the item to “center” solved the issue. For example: <item android:id=”@android:id/progress” android:gravity=”center”> <clip> <shape> <size android:height=”2dp”/> <solid android:color=”@color/my_color”/> </shape> </clip> </item>
I believe the problem is that the Checkbox widget uses a regular TextView with the drawableLeft attribute, because it expects text to be shown as well. (This is why you see it centered vertically, but offset slightly to the left.) If you simply want an image button with multiple states, I suggest using a ToggleButton … Read more
You can create a Drawable or Bitmap from a string path like this: String pathName = “/path/to/file/xxx.jpg”; Drawable d = Drawable.createFromPath(pathName); For a Bitmap: String pathName = “/path/to/file/xxx.jpg”; Bitmap b = BitmapFactory.decodeFile(pathName);
This works for me: android:background=”?android:attr/selectableItemBackground”
I also got bitten by this problem. Very hard to diagnose, even harder to find similar reports and usable solutions. “Tapas” on the freenode #android-dev irc channel came with the following utility method: public static void fixBackgroundRepeat(View view) { Drawable bg = view.getBackground(); if (bg != null) { if (bg instanceof BitmapDrawable) { BitmapDrawable bmp … Read more
You need to create a shape drawable in the drawable folder that looks something like: <?xml version=”1.0″ encoding=”utf-8″?> <shape xmlns:android=”http://schemas.android.com/apk/res/android” android:shape=”oval” > <gradient android:startColor=”#FFFF0000″ android:endColor=”#80FF00FF” android:angle=”270″/> </shape> (For this example I have saved the drawable as circle.xml and it will have a gradient fill) Then in your layout you need to define a view and … Read more
I’m now creating a Drawable like the one pre-compiler.. as i couldn’t change the color to anything but black, even after trying the hex OR described below. The new code: ShapeDrawable footerBackground = new ShapeDrawable(); // The corners are ordered top-left, top-right, bottom-right, // bottom-left. For each corner, the array contains 2 values, [X_radius, // … Read more

If you are creating a chat screen you are probably going to want to implement an incoming speech bubble and an outgoing speech bubble. Here is how I did that : shape_bg_incoming_bubble.xml <?xml version=”1.0″ encoding=”utf-8″?> <layer-list xmlns:android=”http://schemas.android.com/apk/res/android”> <item> <rotate android:fromDegrees=”-45″ android:pivotX=”0%” android:pivotY=”0%” android:toDegrees=”0″ > <shape android:shape=”rectangle” > <solid android:color=”@color/primary” /> </shape> </rotate> </item> <item android:left=”16dp”> … Read more
