RecyclerView datas last row display with multiple time

I don't understand why my recyclerview is only showing the last row of my database although I initialised it with 150 datas.
I searched a lot in the internet and even here on SO, but not one of the solutions is working. Can you help me to figure out why my recyclerView is only showing the last row of the database? Thanks in advance to all of you.
May be you can help me. Here is my code:

I think the problem is here , instead of

...
..
RST_CSTInfo.moveToNext();
}
try this ....
do(RST_CSTInfo.movetofirst()){
// your logic

1.Create a custom dialog and adjust to your needs, e. g. my_dialog.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/tv_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text"/>
<Button
android:id="#+id/btn_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_below="#+id/tv_dialog"
android:text="Button"/>
</RelativeLayout>
2.Declare and open dialog from activity:
my_dialog = new Dialog(context);
my_dialog .requestWindowFeature(Window.FEATURE_NO_TITLE);
my_dialog .setCancelable(true);
my_dialog .setContentView(R.layout.my_dialog);
my_dialog.show();

getting value from two spinner into string variables

I'm trying to pass the strings "año" and "artista" from two spinners to the next activity and I get the value "año" but "artista" is always void. I used this method to get the values in other activity and there it works but here, "artista" is always void. Moreover, I have tried with switch method and without success.
I hope someone helps me and tells me what I'm doing wrong. I read and look for information before ask for help,
This is my code,
public class Buscar extends Activity implements OnItemSelectedListener{
String año;
String artista;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_buscar);
Buscar();
Spinner spinnerBuscarAño = (Spinner) findViewById(R.id.añoSpinner);
String[] añoBuscar = {"1995", "2000", "2005"};
spinnerBuscarAño.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, añoBuscar));
spinnerBuscarAño.setOnItemSelectedListener(this);
Spinner spinnerBuscarArtista = (Spinner) findViewById(R.id.artistaSpinner);
String[] artistaBuscar = {"Michael Jackson", "U2", "Depeche Mode"};
spinnerBuscarArtista.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, artistaBuscar));
spinnerBuscarArtista.setOnItemSelectedListener(this);
}
/*

break;
case R.id.artistaSpinner:
artista = parent.getItemAtPosition(pos).toString();
break;

}
}
*/

if(spinner.getId() == R.id.añoSpinner)
{

}
else if(spinner.getId() == R.id.artistaSpinner)
{
artista = parent.getItemAtPosition(position).toString();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}

Button buttonBuscar = (Button) findViewById(R.id.buscar);
buttonBuscar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(),artista, Toast.LENGTH_SHORT).show();
Intent intentBuscar = new Intent(Buscar.this, ListadoMusica.class);
intentBuscar.putExtra("myaño", año);
intentBuscar.putExtra("myartista", artista);
startActivity(intentBuscar);
}
});
}
}
If someone can help me,
Thanks in advance,

Possibly you are trying to catch a string of intent with another name.
Try this code:
SpinnerTest.java
public class SpinnerTest extends Activity implements AdapterView.OnItemSelectedListener {
String year;
String artist;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.spinner_activity);
Spinner spinnerYear = (Spinner) findViewById(R.id.spinner1);
final String[] years = {"1995", "2000", "2005"};
spinnerYear.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, years));
spinnerYear.setOnItemSelectedListener(this);
Spinner spinnerArtists = (Spinner) findViewById(R.id.spinner2);
final String[] artists = {"Michael Jackson", "U2", "Depeche Mode"};
spinnerArtists.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, artists));
spinnerArtists.setOnItemSelectedListener(this);
Button btnSearch = (Button) findViewById(R.id.btnSearch);
btnSearch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent searchIntent = new Intent(SpinnerTest.this, SearchActivity.class);
searchIntent.putExtra("year", year);
searchIntent.putExtra("artist", artist);
startActivity(searchIntent);
}
});
}
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
switch (adapterView.getId()){
case R.id.spinner1:
year = adapterView.getSelectedItem().toString();
Toast.makeText(SpinnerTest.this, year, Toast.LENGTH_LONG).show();
break;
case R.id.spinner2:
artist = adapterView.getSelectedItem().toString();
Toast.makeText(SpinnerTest.this, artist, Toast.LENGTH_LONG).show();
break;
}
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
SearchActivity.java:
public class SearchActivity extends ActionBarActivity {
String year;
String artist;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_receive_spinner_value);
TextView txtYear = (TextView) findViewById(R.id.txtYear);
TextView txtArtist = (TextView) findViewById(R.id.txtArtist);
if(getIntent().hasExtra("year")){
year = getIntent().getStringExtra("year");
txtYear.setText(year);
}
if(getIntent().hasExtra("artist")){
artist = getIntent().getStringExtra("artist");
txtArtist.setText(artist);
}
}
}
It works for me

How to add image on header in Navigation Drawer

I am using Gabriele Mariotti navigation drawer library to create the sliding menu. It works perfect, but I'm facing with adding an image, as header in it. It should look something like this:
I mean.. not exactly the same, but the idea of having the image as header. Thanks !

I assume you want to achieve something similar to what is in the following picture:
You will have to modify your list adapter(NsMenuAdapter) to support two types of view - item and title where item is clickable and title is just kind of group header. Adapter should takes array/list of objects and every object should have type attribute. This will probably complicate a little OnItemClickListener.
I'm posting my example of that kind list adapter. In my case I created NavigationDrawerItem model to hold information about item type, item 'clickability' and what action should be triggered after item get clicked.
public class NavigationDrawerAdapter extends ArrayAdapter<NavigationDrawerItem> {
private static final String TAG = "NavigationDrawerAdapter";
public NavigationDrawerAdapter(Context context, int resource, NavigationDrawerItem[] objects) {
super(context, resource, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
int itemType = getItemViewType(position);
if (NavigationDrawerItem.TYPE_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
} else if (NavigationDrawerItem.TYPE_ITEM_UNDER_TITLE == itemType) {
convertView = View.inflate(getContext(), R.layout.item_under_title_navigation_drawer, null);
} else {
Log.e(TAG, "Returning default title view - Invalid drawer item type" + itemType);
convertView = View.inflate(getContext(), R.layout.item_title_navigation_drawer, null);
}
}
TextView tv = (TextView) convertView.findViewById(R.id.text);
tv.setText(getContext().getString(getItem(position).stringRes));
return convertView;
}
#Override
public int getItemViewType(int position) {
return getItem(position).type;
}
#Override
public int getViewTypeCount() {
return NavigationDrawerItem.NUMBER_OF_ITEM_TYPES;
}
#Override
public boolean isEnabled(int position) {
return NavigationDrawerItem.isItemClickable(getItemViewType(position));
}
}
And the NavigationDrawerItem class:
public final class NavigationDrawerItem {
private static final String TAG = "NavigationDrawerItem";
// Types must have numbers from 0 to n without gaps.
public static final int TYPE_TITLE = 0;// nonclickable
public static final int TYPE_ITEM_UNDER_TITLE = 1;// clickabel
public static final int NUMBER_OF_ITEM_TYPES = 2;
public final int action;
public final String argument;
public final int type;
//Constructors etc.
public static final boolean isItemClickable(int itemType) {
if (TYPE_TITLE == itemType) {
return false;
} else if (TYPE_ITEM_UNDER_TITLE == itemType) {
return true;
} else {
Log.e(TAG, "Invalid item type " + itemType);
return false;
}
}
}
