    <p>I am trying to implement a custom SimpleCursorAdapter but the problem is, wen i run my application, the listView does not show anything. Why is that? Here is my code:</p> <pre><code>package com.messageHider; import android.content.Context; import android.database.Cursor; import android.provider.MediaStore; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.SimpleCursorAdapter; import android.widget.TextView; import android.widget.Toast; public class myAdapter extends SimpleCursorAdapter { private Context appContext; private int layout; private Cursor mycursor; public myAdapter(Context context, int layout, Cursor c, String[] from,int[] to) { super(context, layout, c, from, to); this.appContext=context; this.layout=layout; this.mycursor=c; } @Override public int getCount() { return 0; } @Override public Object getItem(int arg0) { return null; } @Override public long getItemId(int arg0) { return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater=(LayoutInflater)appContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView=inflater.inflate(layout, null, true); ImageView imageViewVidIcon=(ImageView)convertView.findViewById(R.id.imageViewVidThumb); imageViewVidIcon.setImageResource(R.drawable.videothumb); ImageView imageViewPlayBtn=(ImageView)convertView.findViewById(R.id.imageViewPlaybtn); imageViewPlayBtn.setImageResource(R.drawable.playbtn); TextView textViewTitle=(TextView)convertView.findViewById(R.id.textViewVideoTitle); String title=mycursor.getString(mycursor.getColumnIndex(MediaStore.Video.Media.DISPLAY_NAME)); textViewTitle.setText(title); imageViewPlayBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(appContext, "It works", Toast.LENGTH_LONG).show(); } }); return convertView; } } </code></pre>

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.

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