我正在开发一个语言字典应用程序。我将喜欢的单词保存到首选项中。 XML文件中的喜好内容如下所示:收藏的内容在webview上无法正确显示
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string name="history">
dict_name::160170::hi,dict_name::157140::he-man,dict_name::184774::jet,dict_name::34527::black
</string>
<string name="waitingTime">
0
</string>
<boolean name="saveFavourite" value="true" />
<string name="defaultDictionary">
dict_name
</string>
<string name="favourite">
dict_name::149271::go,dict_name::25481::back,dict_name::184774::jet
</string>
<boolean name="saveHistory" value="true" />
</map>
我用下面的代码加载喜欢的内容进入网页视图:
public class User extends Activity {
private static final String FAVOURITE_TAG = "[MyDict - FavouriteView] ";
private static final String CONTENT_TAG = null;
private ListView mLSTFavourite = null;
private ArrayList<String> lstDict = null;
private ArrayList<Integer> lstId = null;
private ArrayList<String> mWordFavourite = null;
private ArrayAdapter<String> aptList = null;
private SharedPreferences prefs;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.favourite);
prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
if (prefs.getBoolean("saveFavourite", true)) {
String strFavourite = prefs.getString("favourite", "");
Log.i(FAVOURITE_TAG, "Favourite loaded");
if (strFavourite != null && !strFavourite.equals("")) {
mWordFavourite = new ArrayList<String>(Arrays.asList(strFavourite.split(",")));
} else {
mWordFavourite = new ArrayList<String>();
}
} else {
mWordFavourite = new ArrayList<String>();
}
Log.d(FAVOURITE_TAG, "mWordFavourite = " + mWordFavourite.size());
mLSTFavourite = (ListView) findViewById(R.id.lstFavourite);
ImageButton btnClear = (ImageButton) findViewById(R.id.btnClear);
ImageButton btnBackToContent = (ImageButton) findViewById(R.id.btnBackToContent);
if (lstDict == null) {
lstDict = new ArrayList<String>();
lstId = new ArrayList<Integer>();
aptList = new ArrayAdapter<String>(getApplicationContext(), R.layout.customlist);
}
lstDict.clear();
lstId.clear();
aptList.clear();
if (mWordFavourite != null && mWordFavourite.size() > 0) {
try {
for (int i = 0; i < mWordFavourite.size(); i++) {
Log.i(FAVOURITE_TAG, "item = " + mWordFavourite.get(i));
String arrPart[] = mWordFavourite.get(i).split("::");
if (arrPart.length == 3) {
Log.i(CONTENT_TAG, "loaded content " + arrPart.length + ", wordId = " + arrPart[1]);
// Log.i(CONTENT_TAG, "loaded 0");
lstDict.add(i, arrPart[0]);
// Log.i(CONTENT_TAG, "loaded 1");
lstId.add(i, Integer.parseInt(arrPart[1]));
// Log.i(CONTENT_TAG, "loaded 2");
aptList.add(arrPart[2]);
} else {
Log.i(FAVOURITE_TAG, "Wrong entry: " + mWordFavourite.get(i));
}
}
} catch (Exception ex) {
Log.i(FAVOURITE_TAG, "Wrong entry found!");
}
}
// Log.i(CONTENT_TAG,"Adapter size = " + aptList.getCount());
// assign result return
mLSTFavourite.setAdapter(aptList);
mLSTFavourite.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3) {
// mEDWord.setText(mAdapter.getItem(arg2));
Intent i = new Intent();
i.putExtra("dict", lstDict.get(arg2));
i.putExtra("wordId", lstId.get(arg2));
setResult(RESULT_OK, i);
finish();
}
});
btnClear.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
mWordFavourite.clear();
aptList.clear();
mLSTFavourite.setAdapter(aptList);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("favourite", "");
editor.commit();
setResult(RESULT_OK);
finish();
}
});
btnBackToContent.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
setResult(RESULT_CANCELED);
finish();
}
});
}
}
喜好内容加载成功。最喜欢的单词在webview中列出。但问题在于它只显示添加到收藏夹的最新单词的定义,而不管选择了什么单词。例如:
word1
word2
word3
尽管WORD1和/或单词2被选择用于意义,最后一个字的定义,这是WORD3,总是显示。我的目的是当选择word1
时显示word1
的定义,并且当选择word2
时定义word2
,依此类推。我将我的字典数据保存在SQLite数据库中。
有没有人可以帮助解决这个问题。
我试过的代码在你的问题,并尽可能地去它似乎从你的样本数据时返回正确的字典名称和词ID的一个他们在列表视图中被选中。你提到一个Webview和一个数据库,它可能会获得并显示所选单词的数据,如果提供了这些数据的某些细节,可以给予更多的帮助。 – StevieB 2012-03-06 16:58:41
你在这里使用的是什么版本的android? 2.3与股票首选项有问题,我自己碰到它们,这听起来像是熟悉的效果。 – nebulae 2012-09-26 15:12:24
标题中提到了webview,代码中的WebView在哪里? – 2012-10-22 04:48:00
