如何在我的Android程序中访问联系人

我正在制作短信应用程序并希望在我的 Android应用程序中访问联系人
.

我想访问联系人,就像他们在实际联系人列表中的位置一样.选择后,我需要返回我的活动,我可以向该人发送短信.或者是否可以访问存储联系人的数据库？

我的代码如下所示：

String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.disPLAY_NAME)); 
String no = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));

我的LogCat看起来像这样：

谁能帮我？

解决方法

使用此代码选择联系人：

Button button = (Button)findViewById(R.id.pickcontact);

    button.setonClickListener(new OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                 Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
                 startActivityForResult(intent,PICK_CONTACT);
             }
         });



    @Override public void onActivityResult(int reqCode,int resultCode,Intent data){ super.onActivityResult(reqCode,resultCode,data);

    switch(reqCode)
    {
       case (PICK_CONTACT):
         if (resultCode == Activity.RESULT_OK)
         {
             Uri contactData = data.getData();
             Cursor c = managedQuery(contactData,null,null);
          if (c.movetoFirst())
          {
          String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

          String hasPhone =
          c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

          if (hasPhone.equalsIgnoreCase("1")) 
          {
         Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null);
            phones.movetoFirst();
            String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
           // Toast.makeText(getApplicationContext(),cNumber,Toast.LENGTH_SHORT).show();
            setCn(cNumber);
          }
         }
       }
    }
   }
