是否可以将值传递给webView.loadUrl中提到的URL？这样的事情？

webView.loadUrl("file:///android_asset/www/index.html#value="+value);

或者有没有办法将Java String值传递给loadURL中的Javascript函数？

我有以下代码用于将一个关联数组复制到其他,

<script>

var some_db = new Array();

some_db["One"] = "1";

some_db["Two"] = "2";

some_db["Three"] = "3";

var copy_db = new Array();

alert(some_db["One"]);

copy_db = some_db.slice();

alert(copy_db["One"]);


</script>

但第二个警报说"未定义"..我在这里做错了吗？任何指针请..

是否可以在文本视图的某些部分添加onclick？比如我的代码是这样的,

String content = "Hello this a test.. For more details contact @Peter";
someTextView.setText(content);

我想为"@Peter"添加一个onClick事件.那可能吗？

TIA.

在我的Android应用程序中,WebView活动类有以下行,

webView.addJavascriptInterface(new JSInterface(this), "Android");   

在JSInterface类中,我正在初始化Google"SpreadSheetService",如下所示,

import com.google.gdata.client.spreadsheet.SpreadsheetService;

--- some more imports ---


public class JSInterface {
    Context mContext;

    public SpreadsheetService service;

    /** Instantiate the interface and set the context */
    JSInterface(Context c) {
        mContext = c;
        service = new SpreadsheetService("List Demo");
    }

当我运行应用程序时,我得到以下异常,

01-19 21:38:00.652: E/AndroidRuntime(4085): java.lang.ExceptionInInitializerError

其中有以下痕迹

我无法在我的Android应用程序中破解SQLite中的简单更新查询..这是查询,

int fav = 1;
Cursor c = sqliteDB.rawQuery("UPDATE "+ MyConstants.TABLE_NAME + " SET "+MyConstants.TABLE_NAME+"."+MyConstants.ISFAV+ " = "+fav+ " WHERE " +MyConstants.TABLE_NAME+"."+MyConstants.WORD_NAME+ " = \""+word_name+"\"", null);

这是例外,

我的应用程序中有一个viewpager.当用户向右/向左滑动时,我使用TTS引擎说出文本,使用MediaPlayer播放声音.

问题是同时播放..一旦TTS引擎说话文本结束,我该如何播放声音？

PS:我不想睡觉或等待.

更新:

这是我的代码:

@SuppressLint("NewApi")

@Override
public void onInit(int status) {
    if (status == TextToSpeech.SUCCESS) {

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
        } else {
            //Do Something here
        }


        if(Build.VERSION.SDK_INT  >= 15 ){
            UtteranceProgressListener listener = new UtteranceProgressListener() {

                @Override
                public void onStart(String utteranceId) {
                    // TODO Auto-generated method stub

                }

                @Override

                    // TODO Auto-generated method stub

                }

                @Override
