Body
<p>so I have two cursor that read data from database and write data to string, but cursors are always empty even if database have stored data. I checked with SQLite manager that database contain stored data. Log Cat says that log named:"IF1" and "IF2 are executed. Here is my code, I hope someone could find what's wrong..</p> <pre><code>String var; final TextView t = (TextView) findViewById(R.id.textView2); final TextView t2 = (TextView) findViewById(R.id.textView3); Intent intent = getIntent(); var = intent.getStringExtra("datum"); SQLiteDatabase db = openOrCreateDatabase ("MyDB", MODE_PRIVATE, null); String q =" SELECT COALESCE (znak, '') as znak,COALESCE (sprava, '') as sprava, COALESCE(serija, '') as serija, COALESCE(podatak, '') as podatak, COALESCE(ponavljanja, '') as ponavljanja, vrijeme FROM tablica WHERE vrijeme LIKE '"+ var + "'" ; Cursor c = db.rawQuery(q, null); String xy = "SELECT vrijeme FROM tablica WHERE vrijeme LIKE '"+ var + "'"; Cursor dd = db.rawQuery(xy, null); if (dd.getCount() < 1) { Log.d("LIST.DETAILS", "IF1"); dd.close(); db.close(); Toast.makeText(NapredakActivity.this, "Empty!", Toast.LENGTH_SHORT).show(); startActivity(new Intent(this, calendar.class)); } else { String i = ""; dd.moveToFirst(); String st2 = dd.getString(dd.getColumnIndex("vrijeme")); i = "Datum:" +"\t" + st2; t2.setText(i); dd.close(); } if (c.getCount() < 1) { Log.d("LISTA.DETALJI", "IF2"); c.close(); db.close(); Toast.makeText(NapredakActivity.this, "Empty!", Toast.LENGTH_SHORT).show(); startActivity(new Intent(this, calendar.class)); } else { String j = ""; c.moveToFirst(); do { String cm55 = c.getString(c.getColumnIndex("sprava")); String cm = c.getString(c.getColumnIndex("serija")); String cm2 = c.getString(c.getColumnIndex("podatak")); String cm3 = c.getString(c.getColumnIndex("ponavljanja")); String cm_znak = c.getString(c.getColumnIndex("znak")); j = j +cm55+ "\n" + cm + "\t" +cm2 +cm_znak + cm3 ; } while (c.moveToNext()); t.setText(j); c.close(); db.close(); } </code></pre>

Guidance

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.
