由 …衆ロ難τιáo~ 提交于 2019-12-08 03:08:25
问题 I am operating with the compatibility library v7. I am just trying to set the color of my actionbar (for Android 2.1 and above - though I run Android 4.4.2) to a solid color.

问题 I have a program which shows lists of files in directories on the SDCARD and when the user clicks on a file it opens the PDF up. For instance one activity will display the contents of one folder.
