Saya sedang mengembangkan aplikasi kamus bahasa. Saya menyimpan kata favorit ke Preferensi. Konten Favorit dalam file XML terlihat seperti berikut:
<?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>
Saya menggunakan kode berikut untuk memuat konten Favorit ke dalam tampilan web:
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();
}
});
}
}
Konten Favorit berhasil dimuat. Kata-kata favorit tercantum di tampilan web. Tetapi masalahnya adalah itu hanya menunjukkan definisi kata terbaru yang ditambahkan ke Favorit terlepas dari kata apa yang dipilih. Sebagai contoh:
word1
word2
word3
Meskipun kata1 dan / atau kata2 dipilih untuk artinya, definisi dari kata terakhir, yaitu kata3, selalu ditampilkan. Tujuan saya adalah untuk menampilkan definisi word1
kapan word1
dipilih, dan definisi word2
kapan word2
dipilih, dan sebagainya. Saya menyimpan data kamus saya dalam database SQLite.
Adakah yang bisa membantu memecahkan masalah ini.
