我想刪除具有特殊名稱的聯繫人。如何使用名稱刪除Android 2.2中的聯繫人?
我嘗試下面的代碼來找到我的目標:
public Cursor searchByName(String name)
{
try
{
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext())
{
//String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String Name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
if(Name.equals(name))
{
return cur;
}
}
}
}
}
catch (Exception e)
{
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
return null;
}
及以下功能將其刪除:
public void removeContactByName(String name)
{
try
{
Cursor cur = searchByName(name);
if(cur!=null)
{
Uri uri ; // what should it be?
getContentResolver().delete(uri,null, null);
}
else
{
Toast.makeText(getApplicationContext(), "Not Found",Toast.LENGTH_SHORT).show();
}
}
catch (Exception e)
{
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
但我應該URI是什麼?
感謝刪除....怎麼刪除由id.what是功能? –
