问题 As described on Android Developer site: A drawable defined in XML that insets another drawable by a specified distance. This is useful when a View needs a background that is smaller than the View's actual bounds. http://developer.android.com/guide/topics/resources/drawable-resource.html#Inset Instead of just moving the background and leaving the content in place in my case the inset is also moving the TextView.

问题 I've got a really basic app in which I'm trying to insert dynamic checkboxes, and I can get them to appear, but they're not showing with the correct styling. See below - Foo is in the LinearLayout by definition; Bar is being added programmatically. Foo is showing with a grey box for the check, Bar is showing with a white box. Link to image... Here's the code that's creating these: for (Integer i=0; i < arArray.length;i++) { CheckBox cb = new CheckBox(getApplicationContext()); cb.setText("Bar"

问题 I recently installed one more Android SDK to Android Studio, the SDK version 4.4 (API level 19), and after using it with my project, it added a set of mipmap folders in the project's res folder ( res/mipmap ).
