实体键盘在插入设备中后会自动设置一个布局但是可能不是我们想要的。 修改两个功能 根据系统语言设置默认的键盘。
默认添加两个键盘布局到选择键盘布局 的dialog界面 键盘的布局文件apk位置:
frameworks/base/packages/InputDevices/res/raw/
frameworks/base/packages/InputDevices/res/xml/keyboard_layouts.xml 追查设置中的布局找到这里选择键盘布局的Dialogpackages/apps/Settings/src/com/android/settings/inputmethod/KeyboardLayoutDialogFragment.java 点击设置键盘布局会走到 packages/apps/Settings/src/com/android/settings/inputmethod/KeyboardLayoutPickerController.java
查看到 addKeyboardLayoutForInputDevice 设置键盘布局所以利用这里我们添加。
Overridepublic boolean handlePreferenceTreeClick(Preference preference) {if(DEBUG)Log.d(testkeyboard,----handlePreferenceTreeClick---);if (!(preference instanceof SwitchPreference)) {return false;}final SwitchPreference switchPref (SwitchPreference) preference;final KeyboardLayout layout mPreferenceMap.get(switchPref);if (layout ! null) {final boolean checked switchPref.isChecked();if (checked) {mIm.addKeyboardLayoutForInputDevice(mInputDeviceIdentifier,layout.getDescriptor());if(DEBUG)Log.d(testkeyboard,layout.getDescriptor() layout.getDescriptor());} else {mIm.removeKeyboardLayoutForInputDevice(mInputDeviceIdentifier,layout.getDescriptor());}}return true;} 主要修改 frameworks/base/services/core/java/com/android/server/input/InputManagerService.java
addKeyboardLayoutForInputDevice(InputDeviceIdentifier identifier,String keyboardLayoutDescriptor) 如下修改
