import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageButton; import android.widget.ImageView; import android.widget.TextView; import com.androidquery.AQuery; import com.weinco.R; import com.weinco.fragments.StandorteFragment; import com.weinco.webservice.entity.Standort; import com.weinco.webservice.entity.Standorts; public class LocationMenuAdapter extends BaseAdapter { private LayoutInflater mInflater; private AQuery aQuery; private Standorts standorts; private Standort standort; private StandorteFragment standorteFragment; public LocationMenuAdapter(StandorteFragment standorteFragment, Standorts standorts) { this.standorteFragment = standorteFragment; this.standorts = standorts; this.aQuery = standorteFragment.aQuery; mInflater = LayoutInflater.from(standorteFragment.getActivity()); } public int getCount() { return standorts.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public Standort getStandort(int i) { return standorts.get(i); } public View getView(int position, View convertView, ViewGroup parent) { ListContent holder = null; Standort standort = getStandort(position); if (convertView == null) { convertView = mInflater.inflate(R.layout.listviewinflate, null); holder = new ListContent(); holder.text = (TextView) convertView.findViewById(R.id.TextView01); convertView.setTag(holder); } else { holder = (ListContent) convertView.getTag(); } holder.text.setText(standort.Name); return convertView; } class ListContent { TextView text; } } </code></pre> <p>The functions that i use</p> <pre><code> loadLocationMenuList();

    1. COYou should add your logcat output so we can get the origin of the force close.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
