Listview の代わりに GridView を機能させようとしています。コードは ListActivity を使用しています。
public class BorrowerList extends ListActivity implements
LoaderManager.LoaderCallbacks<Cursor> {
private static final int ACTIVITY_PERSON_UPCLOSE = 3;
private SimpleCursorAdapter adapter;
// -----------------------------------------------------------
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grid_view_person_record);
this.getListView().setDividerHeight(2);
fillData();
}
// -----------------------------------------------------------
private void fillData() {
// TODO Auto-generated method stub
String[] from = new String[] { BorrowMeTable.COLUMN_NAME };
int[] to = new int[] { R.id.pername};
getLoaderManager().initLoader(0, null, this);
adapter = new SimpleCursorAdapter(this, R.layout.grid_view_rowitem, null, from,
to, 0);
setListAdapter(adapter);
}
// -----------------------------------------------------------
@Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
//fillData();
}
// -----------------------------------------------------------
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
// Remove to show all records
//String mSelection = BorrowMeTable.COLUMN_NAME + "=?"; // SQL request
//String[] selectionArgs = {"Jack Reacher"}; // The actual argument
BorrowMeContentProvider.distinctSwitch = true;
String[] projection = { BorrowMeTable.COLUMN_ID, BorrowMeTable.COLUMN_NAME };
CursorLoader cursorLoader = new CursorLoader(this,
BorrowMeContentProvider.CONTENT_URI, projection, null, null, null);
return cursorLoader;
}
// -----------------------------------------------------------
@Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor arg1) {
// TODO Auto-generated method stub
adapter.swapCursor(arg1);
}
// -----------------------------------------------------------
@Override
public void onLoaderReset(Loader<Cursor> arg0) {
// TODO Auto-generated method stub
adapter.swapCursor(null);
}
// -----------------------------------------------------------
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// When Clicked - loads record ID and sends it to PersonRecord class
Intent i = new Intent(this, PersonRecord.class);
// Sends a URI request to the content provider saying we are looking for a
// particular record
Uri borrowUri = Uri.parse(BorrowMeContentProvider.CONTENT_URI + "/" + id);
i.putExtra(BorrowMeContentProvider.CONTENT_ITEM_TYPE, borrowUri);
// Activity returns an result if called with startActivityForResult
// startActivityForResult(i, ACTIVITY_PERSON_UPCLOSE);
// Removed the for Result as it would not allow the previous activity
// to release, so it would live people on the list even if all records had been deleted
startActivity(i);
}
}
stackoverflow に関する以前の質問をしたところ、単純な「ListView を GridView に置き換えてください。これは完全に正しい可能性がありますが、まだ完全には理解できていません。
これが私が得るエラーメッセージです：
