    <p>I'm trying to build expandableList with SimpleCursorTreeAdapter but my list does not make groups, it repeats every child element as group element.</p> <p>My datas are formed as KEY_ROWID ,KEY_NAME , KEY_EMAIL ,KEY_ILID ,KEY_KURUMID ,KEY_BOLGEID</p> <hr> <p>my datas:</p> <pre><code>(db,"Asli", "asli@gmail.com", 1, 1, 1); (db,"Osman Can", "osman@gmail.com", 1, 1, 1); (db,"Abuzer Kadayif", "kadayif@gmail.com", 1, 2, 1); (db,"Emre", "emre@gmail.com", 1, 3, 2); (db,"Deniz", "deniz@gmail.com", 1, 4, 2); (db,"Simon Garfunkel", "simon@gmail.com", 1, 5, 0); (db,"Eric Clapton", "eric@gmail.com", 1, 6, 0); (db,"Neil Young", "neil@gmail.com", 1, 5, 0); </code></pre> <hr> <p>And This is my code:</p> <pre><code>String sqlString = "SELECT * " + " FROM " + Items.DATABASE_TABLE; Cursor mCursor = db.rawQuery(sqlString, null); SimpleCursorTreeAdapter mAdapter = new SimpleCursorTreeAdapter(this, mCursor, R.layout.row, R.layout.exprow, //createGroupList(), new String[] { Items.KEY_BOLGEID }, new int[] { R.id.txtItem }, R.layout.exprow, R.layout.exprow, new String[] { Items.KEY_EMAIL,Items.KEY_NAME }, new int[] { R.id.dscItem, R.id.manuItem }) { @Override protected Cursor getChildrenCursor(Cursor groupCursor) { String tempGroup = groupCursor.getString(groupCursor .getColumnIndex(Items.KEY_BOLGEID)); DbHelper dbh = new DbHelper(BrowseActivity.this); SQLiteDatabase db = dbh.getWritableDatabase(); String sqlString = "SELECT " + Items.KEY_ROWID + ", " + Items.KEY_EMAIL + ", " + Items.KEY_NAME + ", " + Items.KEY_KURUMID + ", " + Items.KEY_BOLGEID + ", " + Items.KEY_ILID + " FROM " + Items.DATABASE_TABLE + " WHERE " + Items.KEY_BOLGEID + "= " + tempGroup ; Cursor mCursor = db.rawQuery(sqlString, null); return mCursor; } }; browseView.setAdapter(mAdapter); } </code></pre> <p>My result should be:</p> <pre><code>Group 1: (db,"Asli", "asli@gmail.com", 1, 1, 1); (db,"Osman Can", "osman@gmail.com", 1, 1, 1); (db,"Abuzer Kadayif", "kadayif@gmail.com", 1, 2, 1); Group 2: (db,"Emre", "emre@gmail.com", 1, 3, 2); (db,"Deniz", "deniz@gmail.com", 1, 4, 2); Group 3: (db,"Simon Garfunkel", "simon@gmail.com", 1, 5, 0); (db,"Eric Clapton", "eric@gmail.com", 1, 6, 0); (db,"Neil Young", "neil@gmail.com", 1, 5, 0); </code></pre> <p>But it is 3 times group 1 2 times group 2 3 times group 0</p> <p>And I tried to change sql of groupCursor, but it crashes.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
