问题描述

我如何确保UTF8用于共享preference菜单？我有一个Android preferences菜单，允许用户设置自己的名字，除其他事项。

How do I ensure UTF8 is used for a shared preference menu? I have an android preferences menu that allows a user to set their name, amongst other things.

我需要知道如何存储在共享preferences将数据转换为UTF-8格式

I need to know how to convert the data stored in shared preferences into UTF8 format

在preference菜单的布局在XML中使用utf8编码的文件在res / XML文件夹，名为设置，如下所示：

The preference menu is laid out in xml using utf8 encoding in a file called settings in the res/xml folder and looks like this:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android">
    <EditTextPreference
        android:key="@string/name_key"
        android:title="@string/hof_name_title"
        android:summary="@string/hof_name_summary"
        android:defaultValue="Anonymous" />
    <CheckBoxPreference
        android:key="@string/new_game_preference_key"
        android:title="@string/new_game_preference_title"
        android:summary="@string/new_game_preference_summary"
        android:defaultValue="false" />
</PreferenceScreen>

这是处理这一类是

public class PrefsActivity extends PreferenceActivity implements OnSharedPreferenceChangeListener{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.settings);
    }

    @Override
    protected void onPause() {
        super.onPause();
        // Unregister the listener whenever a key changes
        getPreferenceScreen().getSharedPreferences()
                .unregisterOnSharedPreferenceChangeListener(this);
    }

    @Override
    protected void onResume() {
        super.onResume();
        // Set up a listener whenever a key changes
        getPreferenceScreen().getSharedPreferences()
                .registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
            String key) {
//      Util.log_debug_message("@@@@ Changed prefrence key = " + key);
        if (key.equalsIgnoreCase(getString(R.string.name_key))){
            update_webserver();
        }else if (key.equalsIgnoreCase(getString(R.string.new_game_preference_key))){
            update_webserver();
        }
    }

    protected void update_webserver(){
        Intent webServerReg = new Intent(this, RegService.class);
        webServerReg.putExtra(Config.C2DM_REG_ID_EXTRA, C2DMessaging.getRegistrationId(this));
        startService(webServerReg);     
    }
}

我认为设置＆LT; XML版本=1.0编码=UTF-8＆GT; 将确保文本将是连接codeD UTF8格式，但情况并非总是如此。我在各种格式获得价值。一些例子

I assumed that setting <?xml version="1.0" encoding="utf-8"?> would ensure that text would be encoded in UTF8 format but this is not always the case. I am getting values in all sorts of formats. Some examples

\ NFE \ xF1a，L \ xFAcia，$'\ xE5 \ XEE'，

"\nFe\xF1a", "L\xFAcia", "$'\xE5 \xEE'",

或

":-$B-)O:-):-P=-OB-):-D:-Q:-X:-!:-|\n:'(:-*XDo_O:-X:-C:-X:O:-X=-O;-):-):-);-):-D:OX-(o_O:-V:-@:-V:-X:-Do_O::-C \xBF\xA1\xA1\xAB\xBB\xAE\xA9^\xA5\xA5?[\xA2}?\xA2\xA2\xA5\xA3?$\xBF\xA1\xAE\xA7><[\xA3~?=~~<$c$c>\xB0]\xA3?\xA7\xA1\\\xAB\xBB\xAE^``]]||||}{_|]|||\xB0\xB0?"

":-$B-)O:-):-P=-OB-):-D:-Q:-X:-!:-|\n:'(:-*XDo_O:-X:-C:-X:O:-X=-O;-):-):-);-):-D:OX-(o_O:-V:-@:-V:-X:-Do_O::-C \xBF\xA1\xA1\xAB\xBB\xAE\xA9^\xA5\xA5?[\xA2}?\xA2\xA2\xA5\xA3?$\xBF\xA1\xAE\xA7><[\xA3~?=~~\xB0]\xA3?\xA7\xA1\\\xAB\xBB\xAE^``]]||||}{_|]|||\xB0\xB0?"

是的，这是loooong一套rubish在最后一个例子。

Yes that is one loooong set of rubish in the last example.

我有问题，尝试使用以下code发送NMES作为JSON HTTP POST或PUT请求到我的网络服务器时，启动

The problems I have start when trying to send the nmes as a json HTTP POST or PUT request to my webserver using the following code

public void update(String regId) throws AuthenticationException {
    JSONObject mu_to_send = createJsonToPost(regId, false);
    HttpResponse response;
    try {
        response = HttpRequest.httpPutJSONObject(this,
                Config.UPDATE_USER_URL, mu_to_send);
        int responseCode = response.getStatusLine().getStatusCode();
        String responseJson;
        try {
            responseJson = EntityUtils.toString(response.getEntity());
            String msg = "";

            if (responseCode == 201) {
                // mobile_user = new
                // JSONObject(responseJson).getJSONObject("mobile_user");
                // Broadcast.sendBroadcast(this,
                // ResponseReceiver.ACTION_RESP,
                // Intent.CATEGORY_DEFAULT, Config.C2DM_MESSAGE_EXTRA,
                // Config.BROADCAST_WEBSERVER_USER_CREATED);
            } else {
                msg = "Failed to register with server! HTTP response code = "
                        + responseCode;
            }
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    } catch (ClientProtocolException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

}

public JSONObject createJsonToPost(String regId, boolean set_password) {
    JSONObject holder = new JSONObject();
    JSONObject data = new JSONObject();
    try {
        data.put("auth", regId);
        data.put("name", C2DMessaging.getName(this));
        data.put("receive_new_game_notification",
                C2DMessaging.getGameStartedNotificationPreference(this));
        holder.put("mobile_user", data);
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return holder;
}

public static HttpResponse httpPutJSONObject(Context context, String url,
        JSONObject data) throws ClientProtocolException, IOException,
        AuthenticationException {
    DefaultHttpClient httpclient = getHttpClient(context);
    HttpPut httpput = new HttpPut(url);
    httpput.addHeader("User-Agent", Config.USER_AGENT);
    httpput.addHeader("Accept", "application/json");
    httpput.addHeader("Content-type", "application/json");
    httpput.addHeader(new BasicScheme().authenticate(
            getCredentials(context), httpput));
    StringEntity se = new StringEntity(data.toString());

    httpput.setEntity(se);
    return httpclient.execute(httpput);
}

这会导致各种问题而预计有效的JSON（即UTF8）我的Web服务器上作为JSON应该首先被送到EN codeD的UTF8。

This causes all sorts of issues on my web server which expects valid JSON (i.e. UTF8) as JSON should be sent encoded in UTF8 in the first place.

于是

1）为什么不＆LT; XML版本=1.0编码=UTF-8＆GT; 实际设置UTF8编码？在布局中使用时？

1) Why doesn't <?xml version="1.0" encoding="utf-8"?> actually set UTF8 encoding? when used in the layout?

2）如何最好地确保我总是发送到我的Web服务器有效UTF8格式的字符？如果这种由PUT请求，或由code，它保存到共享preference或或由code表示填充JSON对象或者以上的组合处理？还是其他什么东西？

2) How best to ensure that I always get valid UTF8 format characters sent to my web server? Should this be handled by the put request or by the code that saves to the shared preference or or by the code that populates the json object or perhaps a combination of the above ? or something else?
