The selector that writes textview has learned about the rules for Android to read XML files.

Depressed, I wrote the Android: drawable status at the top of the list for a whole morning.

<Selector xmlns: Android = "http://schemas.android.com/apk/res/android"> <br/> <item Android: state_pressed = "true" Android: drawable = "@ drawable/iamge_pressed"/> <br/> <item Android: state_focused = "true" Android: drawable = "@ drawable/iamge_pressed"/> <br/> <item Android: drawable = "@ drawable/image_photo"/> <br/> </selector> <br/> 

Put Android: drawable to the top, so that when you click the textview control, parse the XML file and you will find that the first one matches multiple conditions, so you will immediately return the value, the image corresponding to the following correct status cannot be displayed.

 

Please note that
