Displaying SQLite data in textview returning null
0
MainData myDBHlpr = new MainData(getActivity());
Cursor csr = myDBHlpr.getAllQuestions(UsageSettings.this);
while (csr.moveToFirst()) {
mMostMessagesSent.setText(csr.getString(csr.getColumnIndex("Reviews")));
mMostMessagesSent.setTextColor(Color.WHITE);
}
I checked row count and it showed 16
Then i checked
Log.d("TAG", csr.getString(cst.getColumnIndex("Reviews")));
And it showed error saying Log needs a message(Which means its null)
But why is it showing null even when the table has 16rows and column name exists
HELPER METHOD
public Cursor getAllQuestions(UsageSettings usageSettings) {
return this.getWritableDatabase().query(TABLE_NAME,null,null,null,null,null,null);
}
