SimpleCursorAdapter not populating a ListView

I'm trying to populate a ListView from an SQLiteDatabase using a SimpleCursorAdapter. There are no errors, and I know the database has data in it, but nothing shows up on the ListView.
Can anyone help find what is going wrong?
1) Layout for the ListView(activity_profilelist.xml)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_profilelist"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation= "vertical"
android:paddingBottom="0dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:paddingTop="0dp"
tools:context="com.corvus.corvusenterprises.digimonapp.Profilelist">
<TextView
android:id="#+id/textView_names"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.1"
android:gravity="center"
android:textAppearance="#android:style/TextAppearance.Theme"
android:textSize="25sp"
android:text="Digimon"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation= "horizontal">
<ListView
android:id="#+id/ListView_names"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="100" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_weight="0.1">
<Button
android:id="#+id/button_update"
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="1"
android:text="Update List">
</Button>
</LinearLayout>
</LinearLayout>
2)Layout for the individual entries in the ListView(activity_list_example.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/Digimon_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="28sp" />
<TextView
android:id="#+id/Digimon_favourites"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="28sp" />
</LinearLayout>

ListView theListView = (ListView) findViewById(R.id.listView_names);

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.activity_list_example,cursor,columns,to,0);

Any and all help is welcome.

There is problem with your simple cursor adapter,
Here you provide three columns
String[]columns = new String[] {"name","favourite","path"};
but here you supply only two views:
int[]to = new int[] {R.id.Digimon_name,R.id.Digimon_favourites};
also in your raw query
String query = "SELECT "+DIGIMON_TABLE_NAME+".ROWID AS _id,
"+DIGIMON_COLUMN_NAME+", "+DIGIMON_COLUMN_FAVOURITE+" FROM
"+DIGIMON_TABLE_NAME;
you provided only "_id", "name" and "favorite" columns and not the "path".

Android multiple contacts from groups and images

I want to do the following.
Pick up three to five contacts out of a special group of contacts or all contacts.
In the list it would be nice to show the contact image.
The selected contacts should have the following information (contact-id, first name, the small version of the contact image to save it as a blob in the database)
I found solutions for the different aspects.
-select multiple contacts:
How to obtain the checked rows in a custom view list
-show contacts from one group
getting contacts from a specified group in android
- photo problem
Getting a Photo from a Contact
But I dont know how to put those together. It would be great if someone could help me putting it together.
Thank you very much!

Android: Refresh cursorloader from a second activity

Have a good day. I'm learning Android development so i'm creating a simple CRUD application, right now i have my main activity that has the listview (MarcaActivity) with the next code:
package com.example.crudapp.activity;
import android.app.Activity;
import android.app.LoaderManager;
import android.content.CursorLoader;

public class MarcaActivity extends Activity implements
LoaderManager.LoaderCallbacks<Cursor> {
MarcaCursorAdapter crsAdap;
ListView lstMarcas;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_marca);
lstMarcas = (ListView)findViewById(R.id.lstMarcas);
lstMarcas.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MarcaActivity.this, MarcaDetailActivity.class);
Uri todoUri = Uri.parse(MarcaCP.CONTENT_URI + "/" + arg3);
i.putExtra("DET", todoUri);
i.putExtra("ACTION", "EXISTING");
startActivity(i);
}
});
getLoaderManager().initLoader(0, null, this);
fillData();
}
protected void onRestoreInstanceState(Bundle savedInstanceState) {
getLoaderManager().restartLoader(0, null, this);
}
#Override

return super.onContextItemSelected(item);
}
private void fillData() {

Then, i have the activity that manages the detail view where i can update or add items, called MarcaDetailActivity:

}
}

}
Toast.makeText(MarcaDetailActivity.this, "Registro registrado",

}
}
#Override

return true;

} }
As you can see in the method guardar of MarcaDetailActivity, first i insert the item using my custom content provider, then i use Toast to show a confirm message, and finally finishing the activity, but when i do that, the listview isn't refreshed via the cursorloader. I read here (stackoverflow) and in other pages that i have to call
getLoaderManager().restartLoader(LIST_ID, null, this);
But in all examples that i found all the stuff (inserting data in the database and refreshing the list) is in the same activity, but in this case i have an activity with the list and the second activity that inserts the item, so i think that i have to call restartLoader from my detail activity, but i don't know how to do that or if that's the right way to do this. I was thinking about saving a reference to the list activity in extras when i create the intent to call the detail activity and have a public method that calls restartLoader but i don't know if that is the best approach. What's the best way to refresh the cursor loader from my detail activity?
And there's my content provider, MarcaCP:

Regards.

Try getContentResolver().notifyChange(MarcaCP.CONTENT_URI, null, false) from the second activity before finishing it.

It's a bit late to answer this.
since in your ContentProvider, you have
getContext().getContentResolver().notifyChange
which is great and correct!
so there is no need to called
getContentResolver().notifyChange(MarcaCP.CONTENT_URI, null, false) from the second activity before finishing it.
the problem is that instead of using getLoaderManager().initLoader
which is deprecated and not life-cycled aware.
try use
LoaderManager.getInstance(this).initLoader
this: is a class that maintains its own android.arch.lifecycle.Lifecycle and android.arch.lifecycle.ViewModelStore. For instance, androidx.fragment.app.FragmentActivity or androidx.fragment.app.Fragment.
so that when you pop back to the first activity and OnResume() called, there is no need to restart the loader again.
P.s. also a great reminder. Do not close any cursor related to the onLoadFinished(#NonNull Loader<Cursor> loader, Cursor cursor)
if doing so will also cause the loader won't update itself after data changed in DB.

You should not store your data in the views as views are recycled and what will happen will almost certainly be what you didn't expect. The following
Addiction addiction = (Addiction) ib.getTag();
....
imageViewAddLog.setTag( addiction );
is not advisable. A better way is to let the list view handle the clicks so that you can know which view has been clicked and the correct Addiction object that corresponds to the view's position.
myList.setOnItemClickListener(
new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View view,
int position, long id) {
Addiction addiction = (Addiction) myList.getItemAtPosition(position);
...rest of code...
}
}
);

Please put all your other code after
convertView.setTag( new AddictionViewHolder(imageViewAddLog, textViewAN, textViewTC, textViewDL, textViewU) );
outside if and try to remove else from code.
rest of code of else will be same after if. Remember that when convertview is null, create a new holder and set in Tag. Then retrieve that object from Tag when convertview is not null. And write all other code like setting values to views etc after
AddictionViewHolder viewHolder = (AddictionViewHolder) convertView.getTag();

listview items disappearing

So.. my listview items are disappearing after they're scrolled off the screen. They're there, you scoll down, back up, and they're gone. After rotation they reappear, but I have no idea why this is happening.

It may be happening because of the background color of surface in which list appears. Try setting the background color to white in linerlayout and text view coolr black then scroll the through the list view again.
