联系人列表在Android M中没有响应

Question

我正在使用RecyclerView显示来自移动联系人的联系人，  这里的问题是“当我尝试将我的应用程序在Android M上运行时它没有响应它会抛出错误

Caused by: java.lang.SecurityException: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{3b9a84a 17730:com.strobilanthes.contactdetials/u0a224} (pid=17730, uid=10224) requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS"

我的代码如下：

 public class MainAct extends AppCompatActivity implements AdapterView.OnItemClickListener {
    private static final int PERMISSIONS_REQUEST_READ_CONTACTS = 100;
    List<String> phno1 = new ArrayList<String>();
    Button select;
    private EditText edtContactFilter;
    private RecyclerView recyclerView;
    private ICEAdapter iceAdapter;
    ArrayList<ContactList> contactLists;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_display);

        recyclerView = (RecyclerView) findViewById(R.id.recycle_view);
        getAllContacts(this.getContentResolver());
        updateCabLsit(contactLists);

        select = (Button) findViewById(R.id.button1);
        select.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                StringBuilder checkedcontacts = new StringBuilder();

                Toast.makeText(MainAct.this, checkedcontacts, Toast.LENGTH_SHORT).show();
            }
        });

        edtContactFilter = (EditText) findViewById(R.id.edt_contact_filter);

    }

    @Override
