本文详细介绍了如何在基于RK3368平台的Android6.0系统上，通过修改SettingsProvider中的defaults.xml文件来更改默认输入法。示例中展示了从拉丁输入法更改为拼音输入法的具体步骤。

Platform: RK3368

OS: Android 6.0

Kernel: 3.10.0

修改Android系统默认输入法：

例如要将默认输入法修改为拼音输入法，可以在overlay中修改:

diff --git a/overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml b/overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

SettingsProvider修改如下：
