InputMethodInfo p = new InputMethodInfo(mContext, ri, additionalSubtypes);

开机阶段

adb logcat | grep "Checking "

可以看到内置的所有输入法的名字

查看 Setting 中我们需要写入的值

在设置的 语言和输入法 界面点击切换输入法.

会出现如下 Log

adb logcat | grep SettingsProvider

05-10 11:52:58.431 891 909 V SettingsProvider: packageValueForCallResult, name = default_input_method, value : com.cootek.smartinputv5/com.cootek.smartinput5.TouchPalIME

所以我们知道了我们需要去操作的值是

default_input_method 和 enabled_input_methods

这里不同版本的 Android 可能 loadStringSetting 的实现不一样.

可以自己看下 loadStringSetting 的实现然后传参.

## 补充:MTK平台FAQ汇总

如果按照如上的步骤没有修改成功，请参考如下步骤进行检查修改：

(1)检查是否成功预置输入法：FAQ13232

(2)检查下setting– language&input 界面，该输入法前面的勾是否选上，没有选上说明此输入法没有被enable，请参考FAQ08909来enable；

(3)检查是否发生语言切换，如果有切换则会恢复默认输入法，若不想因语言变化导致恢复，请参考FAQ12213，FAQ06663

(4)修改默认输入法FAQ04327

06663

【描述】切换系统语言后默认输入法会自动切换到latin输入法，或者系统预置的默认输入法不能生效【解法】

KK、L、M 的解决方案：

可以在文件inputmethodmanagerservice.java中

在构造函数InputMethodManagerService中的最后面，将接收语言改变广播的事件注释掉：

final IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_LOCALE_CHANGED);

mContext.registerReceiver( new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

synchronized(mMethodMap) {

//resetStateIfCurrentLocaleChangedLocked();//将此行注释掉

}

}

}, filter);

这样就可以了。

12213

[DESCRIPTION]

一些版本设置默认输入法不成功，是因为KK比较晚的版本和之后的版本把默认输入法的代码搬到了InputMethodManagerService.java中。

[SOLUTION]

首先查看InputMethodManagerService.java中的systemRunning函数中是否有下面红色的代码，如果有则把红色后面蓝色的语句注释掉即可。

如果没有红色代码可以参考FAQ06663。

if (!mImeSelectedOnBoot) {

Slog.w(TAG, "Reset the default IME as "Resource" is ready here.");

/// M: Loading preinstalled ime from feature option. @{

String preInstalledImeName = IMEFeatureOption.DEFAULT_INPUT_METHOD;

Slog.i(TAG, "IMEFeatureOption defaultIME : " + preInstalledImeName);

if (preInstalledImeName != null) {

InputMethodInfo preInstalledImi = null;

for (InputMethodInfo imi : mMethodList) {

Slog.i(TAG, "mMethodList service info : " + imi.getServiceName());

if (preInstalledImeName.equals(imi.getServiceName())) {

preInstalledImi = imi;

break;

}

}

if (preInstalledImi != null) {

setInputMethodLocked(preInstalledImi.getId(), NOT_A_SUBTYPE_ID);

} else {

Slog.w(TAG, "Set preinstall ime as default fail.");

resetDefaultImeLocked(mContext);

}

}

/// @}

resetStateIfCurrentLocaleChangedLocked();

InputMethodUtils.setNonSelectedSystemImesDisabledUntilUsed(

mContext.getPackageManager(),

mSettings.getEnabledInputMethodListLocked());

}
