本文介绍了在Android 9.0中如何通过输入特定指令在拨号盘来切换设备的语言。这些指令包括:*#0044#（英语）、*#0091#（印地语）等，它们会触发`ChangeLanguageReceiver`广播接收器来更改系统语言。

1、在拨号盘增加指令输入

vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\dialer\dialpadview\SpecialCharSequenceMgr.java

public static boolean handleChars(Context context, String input, EditText textField) {
// get rid of the separators so that the string gets parsed correctly
String dialString = PhoneNumberUtils.stripSeparators(input);

if (handleDeviceIdDisplay(context, dialString)
|| handleRegulatoryInfoDisplay(context, dialString)
|| handlePinEntry(context, dialString)
|| handleAdnEntry(context, dialString, textField)
|| handleSecretCode(context, dialString)
       || handleFactoryTest(context, dialString)
       || handleVersionInfo(context, dialString)
       || handleHardwareInfo(context, dialString)
       || handleAPNInfo(context, dialString)
       || handleSARInfo(context, dialString)
       || handleEngineerTest(context, dialString)
       || handlerChangeLanguage(context, dialString)
       || handleOldTest(context, dialString)
|| ExtensionManager.getDialPadExtension().handleChars(context,
dialString)) {
return true;
}

if (MotorolaUtils.handleSpecialCharSequence(context, input)) {
return true;
}

return false;
}

static boolean handlerChangeLanguage(Context context, String input){
if (input.equals("*#0044#") || input.equals("*#0091#") || input.equals("*#0966#") || input.equals("*#0098#") || input.equals("*#9133#") || input.equals("*#0095#") || input.equals("*#0086#") || input.equals("*#0066#")){
Intent mIntent = new Intent("com.huasi.ACTION_CHANGE_LANGUAGE");
mIntent.putExtra("real_lang",input);
ComponentName cn = new ComponentName("com.android.settings","com.android.settings.ChangeLanguageReceiver");
mIntent.setComponent(cn);
mIntent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);
context.sendBroadcast(mIntent);
return true;
}
return false;
}
