每次我尝试从列表中单击时,应用程序都会崩溃。
ListMovingNames.java

startManagingCursor(cursor);
String[] from = new String[]{SQLHandler.KEY_MOVENAME};
int[] to = new int[]{R.id.text};
SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.row, cursor, from, to);
MoveList.setAdapter(cursorAdapter);
SQLHandlerview.close();
addMove.setOnClickListener(new OnClickListener() {

// TODO Auto-generated method stub
try {
String ssmoveName = etAddMove.getText().toString();

entry.open();
entry.createMove(ssmoveName);
entry.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
MoveList.setOnItemClickListener(new OnItemClickListener() {
@SuppressLint("ShowToast")
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
// TODO Auto-generated method stub
// String moveset = cursor.getString(position);
// temp.setText(moveset);
Toast.makeText(ListMovingNames.this, position, Toast.LENGTH_SHORT);

}
}
这是我的数据库处理程序。但我确定它没有任何问题,它可能是光标适配器。
