问题 I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center.

Please, never mind why I need it. <?xml version=\"1.0\" encoding=\"utf-8\"?> <layer-list xmlns:android=\"http://schemas.android.com/apk/res/android\" > <item> <shape android:shape=\"rectangle\"

问题 I can\'t figure out why the stacked ActionBar I have implemented has a gap between the left most tab and the edge of the screen. This is not the case with the right most tab.

问题 How can I change the focus color (orange) on an EditText box? The focus color is a small rim around the entire control and is bright orange when the control has focus. How can I change the color of that focus to a different color? 回答1: You'll have to create/modify your own NinePatch image to replace the default one, and use that as the background of your EditText. If you look in your SDK folder, under your platform, then res/drawable, you should find the NinePatch image for the EditText focus

See "Referencing style attributes" in the Android Dev

问题 I am using appcompat v7 to get the look consistent on Android 5 and less. It works rather well. However I cannot figure out how to change the bottom line color and the accent color for EditTexts.
