    <p>I have a listview populated from database and on onItemLongClick I have a context menu which I want to use it to edit and update the selected item of list. The problem is that I don' t know how to get the selected item' s values so to use them on another activity which has a form with edittexts. I want when the new activity starts, these string values to be on the apporopriate edittexts. Here is the onItemLongClick code:</p> <pre><code> **REMOVED AND ADDED CORRECT CODE BELOW** </code></pre> <p>With the cursor I get the selected item's values and store them on Strings nameOfSong and artistOfSong. How can I achive when the activity starts to be filled the respective edittexts?</p> <p><strong>==EDIT==</strong> I used SharedPreferences in this way which works:</p> <p>OnItemLongClick of first activity:</p> <pre><code>public boolean onItemLongClick(AdapterView&lt;?&gt; listview, View arg1, final int position, final long arg3) { //bind context menu to listview' s onIitemLongClick(touch and hold) // Get the cursor, positioned to the corresponding row in the result set Cursor cursor = (Cursor) listview.getItemAtPosition(position); // Get the state's capital from this row in the database. registerForContextMenu(listView); openContextMenu(listView); String nameOfSong = cursor.getString(cursor.getColumnIndexOrThrow("songname")); String artistOfSong = cursor.getString(cursor.getColumnIndexOrThrow("artist")); SharedPreferences.Editor editor = prefs.edit(); editor.putString("key1", nameOfSong); editor.putString("key2", artistOfSong); editor.commit(); </code></pre> <p>second activity code:</p> <pre><code>public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.update_item); etEditSong = (EditText) findViewById(R.id.etEditSong); etEditArtist = (EditText) findViewById(R.id.etEditArtist); sEditDance = (Spinner) findViewById(R.id.sUpdDanceList); SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); etEditSong.setText(prefs.getString("key1", null)); etEditArtist.setText(prefs.getString("key2", null)); } </code></pre> <p>Now I'm getting the strings on second activity. Now need to find how to update the database row from above editTexts values.</p>

    1. COdepend on when u are starting Activity ? if u are starting Activity on onItemLongClick then use `Intent` or `Bundle` for sending values to Next Activity on ListView Item Click and if u are starting Activity on menu Click then use `SharedPreferences` for sharing data between Activities

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.
