By default, Android app's interface will change with the direction of the phone, when the phone is in the vertical state, the app's interface is also in the vertical state, and when the phone is in a horizontal screen, the app will automatically switch to the horizontal screen state. In general, the app interface is designed for vertical screen, once automaticall

The progress of human science and technology comes from exploration. The exploration comes from the original discovery. Of course, the App layout is not so advanced. This article is just a summary.This article is a must-have knowledge for android Developers. It is specially compiled and summarized for everyone. It is not perfect but useful. Android interface deve

usually in writing programs often encounter listeners, such as button click Listener, Key Listener and so on. The Listener in Android and the callback function in Java are the same concept, which is to define an interface in the underlying code to invoke the high-level code. So what is a callback function? On the Internet, " in Windows, programmers want the system DLL to call a method of their own writing, and then use the DLL's callback function (CAL

, but some cannot? Why? Because Android 2.2 and later versions are allowed to be moved to the SD card. However, all applications developed earlier do not have this function. So how can I allow your app to move to the SD card? The answer is actually very simple. You only need to set an installLocation attribute for Manifest. This property sets the default installa
