AndroidManifest 之 uses-configuration

 

uses-configuration,可以指定应用程序支持的每个输入机制的组合.可以指定以下输入设备的任意组合.

(1). android:reqFiveWayNav

Whether or not the application requires a five-way navigation control — "true" if it does, and "false" if not. A five-way control is one that can move the selection up, down, right, or left, and also provides a way of invoking the current selection. It could be a D-pad (directional pad), trackball, or other device.

If an application requires a directional control, but not a control of a particular type, it can set this attribute to "true" and ignore the reqNavigation attribute. However, if it requires a particular type of directional control, it can ignore this attribute and set reqNavigation instead.

 

(2). android:reqHardKeyboard (是否支持硬件键盘)

Whether or not the application requires a hardware keyboard — "true" if it does, and "false" if not.

 

(3).android:reqKeyboardType

The type of keyboard the application requires, if any at all. This attribute does not distinguish between hardware and software keyboards. If a hardware keyboard of a certain type is required, specify the type here and also set the reqHardKeyboard attribute to "true".
