از این کد ها استفاده کردم اما جواب نمیده

   public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                startActivityForResult(intent, 3);
            }
        });

 @Override

        super.onActivityResult(reqCode, resultCode, data);

        switch (reqCode) {

در هر صورتی شما باید permition روی توی مانی فست قرار دهید. خودم هم با این مشکل روبرو بودم و تا permition نگذاشتم درست نشد. این هم کد:

 <uses-permission android:name="android.permission.READ_CONTACTS" /> 

من هم همین کدها رو وارد می کنم اما چندتا اررور دارم.

قابل توجه که من این کدها رو در یک کلاس کاستوم ویو که دارم نوشتم یعنی extends شده از LeanierLayout که یک ویو هست.
