Android 修改默认输入法

Android修改默认输入法为搜狗方法如下：

1、修改frameworks/base/packages/SettingsProvider/res/values/defaults.xml 添加一行：

   com.sohu.inputmethod.sogouoem/.SogouIME

注释：com.sohu.inputmethod.sogouoem/.SogouIME 为搜狗输入法ID，若想修改为其它输入法只需要修改这个ID即可。

2、修改frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

在 private void loadSecureSettings(SQLiteDatabase db) {} 方法中添加一行

    loadStringSetting( stmt, Settings.Secure.DEFAULT_INPUT_METHOD,   R.string.config_default_input_method );

    private void loadSecureSettings(SQLiteDatabase db) {        SQLiteStatement stmt = null;        try {            stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"                    + " VALUES(?,?);");            loadBooleanSetting(stmt, Settings.Secure.ETHERNET_ON,R.bool.def_ethernet_on);            loadStringSetting(stmt, Settings.Secure.LOCATION_PROVIDERS_ALLOWED,                    R.string.def_location_providers_allowed);            // 添加搜狗输入法开始            loadStringSetting( stmt, Settings.Secure.DEFAULT_INPUT_METHOD,                    R.string.config_default_input_method );            // 添加搜狗输入法结束            String wifiWatchList = SystemProperties.get("ro.com.android.wifi-watchlist");            if (!TextUtils.isEmpty(wifiWatchList)) {                loadSetting(stmt, Settings.Secure.WIFI_WATCHDOG_WATCH_LIST, wifiWatchList);            }            // 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);            loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_SCRIPT_INJECTION,                    R.bool.def_accessibility_script_injection);            loadStringSetting(stmt, Settings.Secure.ACCESSIBILITY_WEB_CONTENT_KEY_BINDINGS,                    R.string.def_accessibility_web_content_key_bindings);            loadIntegerSetting(stmt, Settings.Secure.LONG_PRESS_TIMEOUT,                    R.integer.def_long_press_timeout_millis);            loadBooleanSetting(stmt, Settings.Secure.TOUCH_EXPLORATION_ENABLED,                    R.bool.def_touch_exploration_enabled);            loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_SPEAK_PASSWORD,                    R.bool.def_accessibility_speak_password);            loadStringSetting(stmt, Settings.Secure.ACCESSIBILITY_SCREEN_READER_URL,                    R.string.def_accessibility_screen_reader_url);            if (SystemProperties.getBoolean("ro.lockscreen.disable.default", false) == true) {                loadSetting(stmt, Settings.System.LOCKSCREEN_DISABLED, "1");            } else {                loadBooleanSetting(stmt, Settings.System.LOCKSCREEN_DISABLED,                        R.bool.def_lockscreen_disabled);            }            loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ENABLED,                    com.android.internal.R.bool.config_dreamsEnabledByDefault);            loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ACTIVATE_ON_DOCK,                    com.android.internal.R.bool.config_dreamsActivatedOnDockByDefault);            loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ACTIVATE_ON_SLEEP,                    com.android.internal.R.bool.config_dreamsActivatedOnSleepByDefault);            loadStringSetting(stmt, Settings.Secure.SCREENSAVER_COMPONENTS,                    com.android.internal.R.string.config_dreamsDefaultComponent);            loadStringSetting(stmt, Settings.Secure.SCREENSAVER_DEFAULT_COMPONENT,                    com.android.internal.R.string.config_dreamsDefaultComponent);            loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_ENABLED,                    R.bool.def_accessibility_display_magnification_enabled);            loadFractionSetting(stmt, Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_SCALE,                    R.fraction.def_accessibility_display_magnification_scale, 1);            loadBooleanSetting(stmt,                    Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_AUTO_UPDATE,                    R.bool.def_accessibility_display_magnification_auto_update);            loadBooleanSetting(stmt, Settings.Secure.USER_SETUP_COMPLETE,                    R.bool.def_user_setup_complete);        } finally {            if (stmt != null) stmt.close();        }    }

3、修改完毕重新编译固件验证修改结果。

调试方法：
