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"?>

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_AVAILABLE_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 );
