視頻中使用的SDK是比較早的版本，有些API已經改了。

 

1.     public void onCreate(Bundle savedInstanceState) {
2.         super.onCreate(savedInstanceState);
3.         // setContentView(R.layout.main);
4.         Cursor c = this.getContentResolver().query(People.CONTENT_URI, null, null, null, null);
5.         this.startManagingCursor(c);
7.         String[] columns = new String[] { People.NAME };
8.         int[] names = new int[] { R.id.row_entry };
10.         mAdapter = new SimpleCursorAdapter(this, R.layout.main, c, columns, names);
11.         this.setListAdapter(mAdapter);
12.     }
14.     @Override
15.     protected void onListItemClick(ListView l, View v, int position, long id) {
16.         super.onListItemClick(l, v, position, id);
17.         
18.         Intent intentCall = new Intent(Intent.ACTION_CALL);
19.         Cursor c = (Cursor) mAdapter.getItem(position);
20.         String phoneId = c.getString(c.getColumnIndex(People.PRIMARY_PHONE_ID));
21.         intentCall.setData(Uri.withAppendedPath(Phones.CONTENT_URI, phoneId));
22.         startActivity(intentCall);
23.     }
