当我把它放在我的 layout.xml 

<CalendarView
    android:id="@+id/calendarView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

我的活动停止工作，所以当我单击按钮打开它时，设备被挂起。

我的活动代码

public class Reservation extends Activity {

    private Button AddReservation;

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

            @Override
            public void onClick(View v) {    
            finish();                   
            }
        });
    }

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

}

使用自定义日历

在你的活动中

 String date="";
GridView grid;
ImageView left,right;

    right.setOnClickListener(new View.OnClickListener() {
