将mp3铃声设为特定联系人

Question

我想将mp3歌曲设置为特定联系人。在这里，我点击所选的上下文菜单项，在列表视图中显示联系人。我想将mp3歌曲设置为从listview中选择的联系人项目，但铃声未设置。这是我的代码：     公共类RingtoneActivity扩展了Activity {

Context ctx;
TextView songescape;

ListView listContacts;
Uri queryUri;
String[] projection;
String selection;
// crsorLoader crsorLoader;
Cursor cursor;
ListAdapter adapter;
String contactId;

protected static final int CONTEXTMENU_OPTION1 = 1;
protected static final int CONTEXTMENU_OPTION2 = 2;
protected static final int CONTEXTMENU_OPTION3 = 3;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ringtone);
    ctx = this;
    songescape = (TextView) findViewById(R.id.ringtonetext);
    registerForContextMenu(songescape);

}

public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);

    // Set title for the context menu
    menu.setHeaderTitle("Set as");

    // Add all the menu options

    menu.add(1, 1, CONTEXTMENU_OPTION1, "Default Ringtone");
    menu.add(1, 2, CONTEXTMENU_OPTION2, "Ringtone to specific Contact");
    menu.add(1, 3, CONTEXTMENU_OPTION3, "Ringtone to Contact Group");
}

public boolean onContextItemSelected(MenuItem item) {

    // Get extra info about list item that was long-pressed
    AdapterContextMenuInfo menuInfo = (AdapterContextMenuInfo) item
            .getMenuInfo();

    // Perform action according to selected item from context menu
    switch (item.getItemId()) {

    case CONTEXTMENU_OPTION1:
        // set as default ringtone
        setRingTone();

        break;

    case CONTEXTMENU_OPTION2:

        // 1:retrieve contacts from phone

        setContentView(R.layout.activity_main);
        listContacts = (ListView) findViewById(R.id.conactlist);

        Uri contactData = ContactsContract.Contacts.CONTENT_URI;
        // contactId = contactData.getLastPathSegment();



        // changes
        // you can retrieve all contacts as a cursor.

        cursor = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                null, null, null);

        // now we have cusror with contacts and get diffrent value from
        // cusror.

        // final String[] contactid={ContactsContract.Contacts.};

        String[] from = { ContactsContract.Contacts.DISPLAY_NAME };
        int[] to = { android.R.id.text1 };

        // Above code,get all contact name and phone numbers from your phone
        // and sim.

        ListAdapter adapter = new SimpleCursorAdapter(this,
                android.R.layout.simple_list_item_1, cursor, from, to,
                CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
        listContacts.setAdapter(adapter);
