Load and display Contact android

Question

I wanted to ask if someone can help me. I'd like to load a contact from my contactlist in android to my view as text or in a listview. I have a button that says "Add Contacts" the Button Name is addcontacts. I have a ContactView Activity where i already Setup everything. I've coded something already but thats not what i want to do.

public class ContactView extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_contact_view);
        Button insert = (Button) findViewById(R.id.addcontact);
        insert.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                insert();
            }
        });
    }

    public void insert() {
        Intent intent = new Intent(
                ContactsContract.Intents.SHOW_OR_CREATE_CONTACT,
                ContactsContract.Contacts.CONTENT_URI);
        intent.setData(Uri.parse("tel:011-9999999"));//specify your number here
        intent.putExtra(ContactsContract.Intents.Insert.COMPANY, "Google");
        intent.putExtra(ContactsContract.Intents.Insert.POSTAL,
                "Addresse, Street Name, State/Country");
        startActivity(intent);
        Toast.makeText(this, "Lade Ansicht", Toast.LENGTH_SHORT).show();
    }

    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.contact_menu, menu);
        return true;
    }

This is what i already have. This lets me create Contacts inside my App but thats not the way it should be because i want to display Contacts that are already created. When i let the user create them within the app they'll have double Contacts.

Can someone help me load them from existing Contacts and display them in my way??

your final code

public class ContactView extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_contact_view);
    Button insert = (Button) findViewById(R.id.addcontact);
    insert.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            scanContacts();
        }
    });
}

public void insert() {
    Intent intent = new Intent(
            ContactsContract.Intents.SHOW_OR_CREATE_CONTACT,
            ContactsContract.Contacts.CONTENT_URI);
    intent.setData(Uri.parse("tel:011-9999999"));//specify your number here
    intent.putExtra(ContactsContract.Intents.Insert.COMPANY, "Google");
    intent.putExtra(ContactsContract.Intents.Insert.POSTAL,
            "Addresse, Street Name, State/Country");
    startActivity(intent);
    Toast.makeText(this, "Lade Ansicht", Toast.LENGTH_SHORT).show();
}

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.contact_menu, menu);
    return true;
}




private void scanContacts() {

    boolean createContact = true;

    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) {
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                        new String[]{id}, null);


                while (pCur.moveToNext()) {

                    //Your condition here to check the input number is already in contact list 
                    if(your_condition){
                        createContact = false;//
                    }       


                    String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    Log.d("\n\nName: " + name , "Phone No: " + phoneNo);
                }
                pCur.close();
            }
        }
    }

    if(createContact){
            create();
            }   
}

You can get number & name from your phone contacts by following code

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
        while (phones.moveToNext())
        {
        String Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)
        String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

        }
