I´m developing an android app and I want to display some data from a database in a ListView with a Title and Subtitle. I did an adapter extending SimpleCursorAdapter and it´s working but it shows the 2 first fields and no what I choose in the method BindView. I´m trying to find the error but I can´t, probably it´s something really stupid but that errors is really hard to find by yourself :-) So that's the code of the adapter:
package com.apeirons.apeironsdatabasemanager;
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
public class MyListAdapter extends SimpleCursorAdapter {
//private Context context;
LayoutInflater inflater;
@SuppressWarnings("deprecation")
public MyListAdapter(Context context, int layout, Cursor c, String[] from,
int[] to) {
super(context, R.layout.consult, c, from, to);
inflater = LayoutInflater.from(context);
}
public void bindview (View view, Context context, Cursor cursor){
TextView titulo = (TextView)view.findViewById(R.id.Titulo);
titulo.setText(cursor.getString(cursor.getColumnIndex("name")));
TextView subtitulo = (TextView)view.findViewById(R.id.SubTitulo);
subtitulo.setText(cursor.getString(cursor.getColumnIndex("kind_place")));
subtitulo.append(cursor.getString(cursor.getColumnIndex("score")));
}
@Override
public View newView (Context context, Cursor cursor, ViewGroup parent){
View v = inflater.inflate(R.layout.entrys, parent, false);
return v;
}
}
And here is where I use the adapter:
package com.apeirons.apeironsdatabasemanager;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListView;
public class Consult extends Activity {
private ListView list;
private SQLiteDatabase db;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.consult);
list = (ListView)findViewById(R.id.list);
this.getIntent();
ApeironsSQLiteHelper apeironsdb = new ApeironsSQLiteHelper(this, "DBApeirons.DB", null, 1);
db = apeironsdb.getReadableDatabase();
String[] campos = new String[]{"_id", "name", "kind_place", "score"};
Cursor c = db.query("Apeirons", campos, null, null, null, null, null);
int cuenta = c.getCount();
c.moveToFirst();
Log.d("CONSULTA", Integer.toString(cuenta));
Log.d("CURSOR", c.getString(c.getColumnIndex("score")));
String[] from = new String[]{"name", "kind_place", "score"};
int [] to = new int[] {R.id.Titulo, R.id.SubTitulo};
//@SuppressWarnings("deprecation")
MyListAdapter myadapter = new MyListAdapter (this,
R.layout.entrys, c, from, to);
list.setAdapter(myadapter);
}
}
Really thank you for your help.
You are not overriding the bindView
method of SimpleCursorAdapter
, but defining a new method bindview
(not the capitalisation!) which is called nowhere.
Because your new method is public in a public class, you won't be warned by the compiler that it is unused.
If you had used the @Override
annotation, your compiler would have warned you that you don't actually override a method...
