Android Studio Auto Import (All) package import

http://blog.csdn.net/buaaroid/article/details/44979629

1 Android Studio Only import the shortcut keys for a single package: Alt+enter. There are no shortcut keys for quick import packages under Eclipse Ctrl+shift+o.

2 There is an auto import feature in the Android studio settings. The setup process is as follows:

Android Studio--file--> Settings-----Auto Import: Then set up like 1.

Figure 1

The parameters in the settings are explained below, reproduced as follows:

XML
Show Import Popup, which is used for editing XML, automatically pops up an import dialog box asking if you need to import.

Java

Insert Imports on paste:(all ask None), which is actually an option for you to ask for an imported package when you copy the code .
All: When you need to import the package name, it will be imported automatically, will not play the prompt box
ask: When you need to import the package name, a pop-up box asks if you want to import
None: When you need to import a package name, the prompt box does not bounce and is not imported automatically.

Show Import Popup: This is different from the above insert imports on paste. Ha, don't mix, this means that when the declaration of the class you entered is not imported, a selection dialog box pops up. but this is a bit of a problem to note here. Whether you check or not, anyway, the dialog box will not pop out, after you lose the class name, the declaration is automatically imported. So I guess this could be a bug in Android studio.
Optimize imports on fly: This is actually the same as the shortcut key Ctrl+shift+o/ctrl+alt+o, which is to remove the unused declarations.
Add Unambiguous importson the fly: This is the automatic import function, when you enter the class name, the declaration is automatically imported.

Exclude from Import and completion: This is actually your custom Import. You don't have to pay attention, generally you can't use it.
