    text
    copied!<p>I have an issue with <code>Spinners</code> in a <code>ListView</code>. I have a <code>ListView</code> with a <code>CheckBox</code>, a label, and two <code>Spinners</code>. The <code>Spinner</code> are populated from SQLite and that is working fine. I am not using the <code>ViewHolder</code> method because so far when the <code>ListView</code> row is clicked the <code>CheckBoxes</code> are checked or unchecked and the change is immediately saved to the database. When the row is checked the <code>Spinners</code> are made visible but are not visible when the row is not checked.</p> <p>So the issue that I haven't managed to find a solution for is that I have no idea how to get the actual <code>Spinner</code> or even get the <code>ListItem</code> row that the clicked <code>Spinner</code> is on. The <code>Activity</code> extends <code>ListActivity</code>. Anyone know a way I can do this without using a <code>ViewHolder</code> or do I have to use a <code>ViewHolder</code>?</p> <p>Here is the code that declares and populates the <code>ListView</code>:</p> <pre><code>mSsCursor = mDbHelper.fetchAllSsPlaylistSs(mPlId); startManagingCursor(mSsCursor); String[] from = new String[]{"pl_selected", BTDbAdapter.KEY_NAME, BTDbAdapter.KEY_NAME2}; int[] to = new int[]{R.id.pl_selected, R.id.name, R.id.name2}; mAllSs = new SimpleCursorAdapter(this, R.layout.pl_edit_ss_row, mSsCursor, from, to); mAllSs.setViewBinder(new SimpleCursorAdapter.ViewBinder() { //custom handling of setting the value public boolean setViewValue(View view, Cursor cursor, int columnIndex) { if(columnIndex == 3) { ViewGroup row = (ViewGroup)view.getParent().getParent(); mSId = cursor.getInt(0); if (cursor.getInt(3) &gt; 0) { mCheckBox = (CheckBox) row.findViewById(R.id.pl_selected); mCheckBox.setChecked(true); mTSpin = (Spinner) row.findViewById(R.id.pl_t_spin); mMSpin = (Spinner) row.findViewById(R.id.pl_m_spin); mtvT = (TextView) row.findViewById(R.id.pl_t); mtvM = (TextView) row.findViewById(R.id.pl_m); mTSpin.setVisibility(View.VISIBLE); mtvT.setVisibility(View.VISIBLE); mMSpin.setVisibility(View.VISIBLE); mtvM.setVisibility(View.VISIBLE); //set the values in the t spinner PopulateTSpinner(cursor.getInt(4)); //set the values in the m spinner PopulateMSpinner(cursor.getInt(5)); } else { mCheckBox = (CheckBox) row.findViewById(R.id.pl_selected); mCheckBox.setChecked(false); mTSpin = (Spinner) row.findViewById(R.id.pl_t_spin); mMSpin = (Spinner) row.findViewById(R.id.pl_m_spin); mtvT = (TextView) row.findViewById(R.id.pl_t); mtvM = (TextView) row.findViewById(R.id.pl_m); mTSpin.setVisibility(View.GONE); mtvT.setVisibility(View.GONE); mMSpin.setVisibility(View.GONE); mtvM.setVisibility(View.GONE); } return true; } return false; } }); setListAdapter(mAllSs); </code></pre> <p>Thanks.</p>
