我正在制作Android歌曲应用。一切都很好......除了搜索部分。歌曲存储在MySQLite数据库中,当我打开一首歌时,它会正常打开。但是当我搜索一首歌然后尝试从搜索结果中打开这首歌时,它不会打开实际的歌曲,但它会打开另一首歌。例如,如果我搜索这首歌,古代词,它会打开另一首歌,一个荣耀之地的家。
这是我的MainActivity:

import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.content.Intent;

import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
private EditText filterText;
private ArrayAdapter<String> listAdapter;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
filterText = (EditText)findViewById(R.id.editText);
ListView itemList = (ListView)findViewById(R.id.listView);
DbBackend dbBackend = new DbBackend(MainActivity.this);
String[] terms = dbBackend.dictionaryWords();
listAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, terms);
itemList.setAdapter(listAdapter);
itemList.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
// make Toast when click
Toast.makeText(getApplicationContext(), "Song " + position, Toast.LENGTH_SHORT).show();
Intent intent = new Intent(MainActivity.this, SongbookActivity.class);
intent.putExtra("SONG._ID",position);
startActivity(intent);
}
});
filterText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
MainActivity.this.listAdapter.getFilter().filter(s);
}
@Override
public void afterTextChanged(Editable s) {
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long

int id = item.getItemId();

return true;
}
return super.onOptionsItemSelected(item);
}
}
这是SongbookActivity:

public class SongbookActivity extends ActionBarActivity {
private TextView lyrics;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_song);
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
int dictionaryId = bundle.getInt("SONG._ID");
int id = dictionaryId + 1;
TextView title = (TextView)findViewById(R.id.title);
lyrics = (TextView)findViewById(R.id.lyrics);
DbBackend dbBackend = new DbBackend(SongbookActivity.this);
SongObject allQuizQuestions = dbBackend.getQuizById(id);
title.setText(allQuizQuestions.getWord());
lyrics.setMovementMethod(new ScrollingMovementMethod());
lyrics.setText(allQuizQuestions.getDefinition());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_songbook, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPause() {
if(convertToSpeech != null){
convertToSpeech.stop();
convertToSpeech.shutdown();
}
super.onPause();
}
}
如果我从过滤结果中点击它,我希望能够查看正确的歌曲
