During development, some operations are sometimes performed in the thread class, and some operations are crash due to different versions of Android, especially the lower version, so it is necessary to see if some of the crash-prone operations are in

We all know that there are two ways to implement certain features in Android: One is to set the corresponding attribute in the XML file, and the other is to implement it in code. Similarly, the Android implementation of full-screen display can also

There are four ways to pass values:1. Attribute passing value 2. Single-pass value 3. Proxy value 4.block value one. Property pass-through value(front-to- back ) 1. The following interface defines a property to store the value passed over the
