关于Android2.2定制出厂默认输入法的一些心得

有些输入法预制到系统中时默认情况下是不能直接使用的，要在设置->语言和键盘中勾选相应输入法，这里提供了一种参考改进，使预制输入法直接可用。

共有两处修改,第一处：

在android2.2中，一些系统定制信息是通过

frameworks/base/package/settingsproviders/res/values/defaults.xml来预设的，在系统首次启动时加载此文件，并应用文件中的设置。文件如下：

<?xml version="1.0" encoding="utf-8"?>

</resources>

其中语句<string name="def_enabled_input_methods">com.sohu.inputmethod.sogou/.SogouIME:com.android.inputmethod.pinyin/.PinyinIME</string>

是我们要增加的，表示默认使能google拼音和搜狗拼音，并且这条语句放在最后面的输入法做为系统默认输入法，也就是首选输入法。

第二处：

在文件frameworks/base/package/settingsproviders/src/com/android/providers/settings/DatabaseHelper.java的函数

loadSecureSettings()中增加一条语句，制定默认使能的输入法

//added by folksy , for input methods

loadStringSetting(stmt, Settings.Secure.ENABLED_INPUT_METHODS,

R.string.def_enabled_input_methods);

如：

private void loadSecureSettings(SQLiteDatabase db) {

SQLiteStatement stmt = null;

try {

stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"

+ " VALUES(?,?);");

loadBooleanSetting(stmt, Settings.Secure.BLUETOOTH_ON,

R.bool.def_bluetooth_on);

// Data roaming default, based on build

loadSetting(stmt, Settings.Secure.DATA_ROAMING,

"true".equalsIgnoreCase(

SystemProperties.get("ro.com.android.dataroaming",

"false")) ? 1 : 0);

loadBooleanSetting(stmt, Settings.Secure.INSTALL_NON_MARKET_APPS,

R.bool.def_install_non_market_apps);

loadStringSetting(stmt, Settings.Secure.LOCATION_PROVIDERS_ALLOWED,

R.string.def_location_providers_allowed);

//added by bwu , for input methods

loadStringSetting(stmt, Settings.Secure.ENABLED_INPUT_METHODS,

R.string.def_enabled_input_methods);

loadBooleanSetting(stmt, Settings.Secure.ASSISTED_GPS_ENABLED,

R.bool.assisted_gps_enabled);

loadIntegerSetting(stmt, Settings.Secure.NETWORK_PREFERENCE,

R.integer.def_network_preference);

loadBooleanSetting(stmt, Settings.Secure.USB_MASS_STORAGE_ENABLED,

R.bool.def_usb_mass_storage_enabled);

loadBooleanSetting(stmt, Settings.Secure.WIFI_ON,

R.bool.def_wifi_on);

loadBooleanSetting(stmt, Settings.Secure.WIFI_NETWORKS_***AILABLE_NOTIFICATION_ON,

R.bool.def_networks_available_notification_on);

String wifiWatchList = SystemProperties.get("ro.com.android.wifi-watchlist");

if (!TextUtils.isEmpty(wifiWatchList)) {

loadSetting(stmt, Settings.Secure.WIFI_WATCHDOG_WATCH_LIST, wifiWatchList);

}

// Set the preferred network mode to 0 = Global, CDMA default

int type = SystemProperties.getInt("ro.telephony.default_network",

RILConstants.PREFERRED_NETWORK_MODE);

loadSetting(stmt, Settings.Secure.PREFERRED_NETWORK_MODE, type);

// Enable or disable Cell Broadcast SMS

loadSetting(stmt, Settings.Secure.CDMA_CELL_BROADCAST_SMS,

RILConstants.CDMA_CELL_BROADCAST_SMS_DISABLED);

// Set the preferred cdma subscription to 0 = Subscription from RUIM, when available

loadSetting(stmt, Settings.Secure.PREFERRED_CDMA_SUBSCRIPTION,

RILConstants.PREFERRED_CDMA_SUBSCRIPTION);

// Don't do this. The SystemServer will initialize ADB_ENABLED from a

// persistent system property instead.

//loadSetting(stmt, Settings.Secure.ADB_ENABLED, 0);

// Allow mock locations default, based on build

loadSetting(stmt, Settings.Secure.ALLOW_MOCK_LOCATION,

"1".equals(SystemProperties.get("ro.allow.mock.location")) ? 1 : 0);

loadSecure35Settings(stmt);

loadBooleanSetting(stmt, Settings.Secure.MOUNT_PLAY_NOTIFICATION_SND,

R.bool.def_mount_play_notification_snd);

loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_AUTOSTART,

R.bool.def_mount_ums_autostart);

loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_PROMPT,

R.bool.def_mount_ums_prompt);

loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_NOTIFY_ENABLED,

R.bool.def_mount_ums_notify_enabled);

} finally {

if (stmt != null) stmt.close();

}

}

重新编译即可。

小技巧：修改以上文件，可以重新编译整个system，也可进入frameworks/base/package/settingsproviders/目录下，使用mm命令编译,然后打包system。

设置默认输入法
在 frameworks\base\core\res\res\values\config.xml　添加一个属性:
<!--leo add-->
<string name="config_default_input_method">com.android.inputmethod.pinyin/.PinyinIME</string>


frameworks\base\services\java\com\android\server\InputMethodManagerService.java
的方法buildInputMethodListLocked()里添加:
String defaultIme = Settings.Secure.getString(mContext
.getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);
//leo
if ( defaultIme == null )
{
final Resources res = mContext.getResources();
try
{
//frameworks\base\core\res\res\values\config.xml
String myIME = res.getString( com.android.internal.R.string.config_default_input_method );
if ( myIME != null && myIME.length() > 0 )
{
Settings.Secure.putString( mContext.getContentResolver(),
Settings.Secure.DEFAULT_INPUT_METHOD,
myIME );
}
}
catch ( Exception e )
{
}

}



下面的方法也可:

设置默认输入法为google拼音
\frameworks\base\packages\SettingsProvider\res\values\defaults.xml
<!-- leo add -->
<string name="config_default_input_method" translatable="false">com.android.inputmethod.pinyin/.PinyinIME</string>

\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java
private void loadSecureSettings(SQLiteDatabase db)
//leo add
loadStringSetting( stmt, Settings.Secure.DEFAULT_INPUT_METHOD,
R.string.config_default_input_method );
