How can I modify this code so it can highlight the search result in the listView?
Here's the full code of my project.
public class MainActivity extends Activity implements OnItemClickListener, TextWatcher {
private ListView daftarLagu;
private String[] tampungLaguLirik = null;
protected static String strSearchLyric = null;
// Test Highlight
private String mSearchText;
//deklarasi keperluan untuk database
private SQLiteDatabase db = null;
private Cursor LaguCursor = null;
private DatabaseSong datalagu = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
datalagu = new DatabaseSong(this);
db = datalagu.openDataBase();
db = datalagu.getReadableDatabase();
datalagu.onCreate(db);
//buat object dari dataLagu
setContentView(R.layout.activity_search);
daftarLagu = (ListView)findViewById(R.id.listIndexLagu);
//buat listener dari list view pada aplikasi pencarian tanaman obat
daftarLagu.setOnItemClickListener(this);
//Tombol Ganti Jenis Pencarian
TextView text = (TextView) findViewById(R.id.pencarian);
text.setText("PENCARIAN LIRIK LAGU");
Button nomorBtn = (Button) findViewById(R.id.btnSwitchPencarian);
nomorBtn.setText("CARI NOMOR, JUDUL, PENGARANG");
nomorBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
db.close();
//startActivity(new Intent(MainActivity.this, SearchActivity.class));
}
});
//Tombol Cari Lagu
EditText textCari = (EditText)findViewById(R.id.editTextcari);
textCari.setHint("Masukan Potongan Lirik Lagu");
textCari.addTextChangedListener(this);
}
//buat overread method dari set on item click listener
public void onItemClick(AdapterView<?> arg0, View arg1, int posisi, long arg3) {
Toast.makeText(MainActivity.this, "ini pas saya click", Toast.LENGTH_SHORT).show();
//Toast.makeText(SearchLyricActivity.this, ""+tampungLaguLirik[posisi], Toast.LENGTH_SHORT).show();
//panggil method yang dibuat untuk handler tampilkan gambar dari data tanaman

posisi = 0;
}
//fungsi

I really have no idea, I already search the answers related to this, but I just don't know how to implement all the logic or code to my code. I'm still using Eclipse. This is a project that I made before the official IDE change to Android Studio.
please give me an example base on my code.
I Already tried to use spannable but it doesn't work here's the code I add a method but still doesn't work, what did i missed?
private Spannable highlightSearchKey(String title) {
Spannable highlight;
Pattern pattern;
Matcher matcher;
int word_index;
String title_str;
word_index = tampungLaguLirik.length;
title_str = Html.fromHtml(title).toString();
highlight = (Spannable) Html.fromHtml(title);
Toast.makeText(MainActivity.this, "Word Index "+word_index+" terus "+title_str+" Span "+highlight, Toast.LENGTH_SHORT).show();
for (int index = 0; index < word_index; index++) {
pattern = Pattern.compile("(?i)" + tampungLaguLirik[index]);
matcher = pattern.matcher(title_str);
while (matcher.find()) {
highlight.setSpan(
new BackgroundColorSpan(0x44444444),
matcher.start(),
matcher.end(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
}
return highlight;
}
and call this method here:
//Untuk menampilkan daftar lagu pada Index Lagu
LaguCursor = db.rawQuery("SELECT (UPPER('\n\n___ '||nomor||'. '||judul)||'\n\n'||lirik) FROM tbl_Lagusion WHERE lirik LIKE '%"+value+"%' ", null);
tampungLaguLirik = new String[LaguCursor.getCount()];
LaguCursor.moveToFirst();
Toast.makeText(MainActivity.this, "klot "+LaguCursor.getCount(), Toast.LENGTH_SHORT).show();
for (int cc=0; cc < LaguCursor.getCount(); cc++)
{
Hitung = Hitung +1;
LaguCursor.moveToPosition(cc);
tampungLaguLirik[cc] = LaguCursor.getString(0).toString();
highlightSearchKey(value);
}
but still I cannot highlight the same character that i type in editText field.
