I want to display the data from content provider in gridview more than 3 sub items or line
here is my java source code
@Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor cursor) {
players.clear();
// First Check if cursor is not null
if(cursor != null ) {
StringBuilder result = new StringBuilder();
// Now loop to all items and append it to string builder
while (cursor.moveToNext()) {
String id = cursor.getString(cursor.getColumnIndex("ID"));
String name = cursor.getString(cursor.getColumnIndex("ITEM_NAME"));
String qty = cursor.getString(cursor.getColumnIndex("QUANTITY"));
String inst = cursor.getString(cursor.getColumnIndex("INSTRUCTION"));
String pid = cursor.getString(cursor.getColumnIndex("POS_ID"));
players.add("Items :" + name + "\n" + "Qty :" + qty + "\n" +
"Details :" + inst + "\n" + " Pos ID :" + pid);
gv.setAdapter(adapter);
resultView.setText(result);
}
} else {
// If cursor is null then display toast amd set empty data.
resultView.setText("Empty data");
Toast.makeText(MainActivity.this, "May be there is no app corresponding to your provider or there is null data.",
Toast.LENGTH_LONG).show();
}
}
the gv.setAdapter(adapter) is where i display the data coming from the content provider
and here is my xml source code
<?xml version="1.0" encoding="utf-8"?>
