不能從GitHub項目

Question

設置的onClick期運用材料calendarview我從https://github.com/prolificinteractive/material-calendarview

我實現OnDateSelectedListener和@Override onDateSelected參考，但沒有工作，當我clcik日曆天任。

爲什麼？

任何人都可以教我點我錯過了什麼？在此先感謝

gradle這個項目：

compile 'com.prolificinteractive:material-calendarview:1.4.3' 

佈局的xml：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.user.testcalendar0420_1.MainActivity"> 

    <com.prolificinteractive.materialcalendarview.MaterialCalendarView 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/calendarView" 
     android:layout_width="368dp" 
     android:layout_height="wrap_content" 
     app:mcv_showOtherDates="all" 
     app:mcv_selectionColor="#00F" 
     tools:layout_editor_absoluteY="0dp" 
     tools:layout_editor_absoluteX="8dp" /> 

</LinearLayout> 

我的日曆類：

public class MainActivity extends AppCompatActivity implements OnDateSelectedListener { 

    private MaterialCalendarView calendarView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     //I can see the calendar on screen 
     calendarView = (MaterialCalendarView) findViewById(R.id.calendarView); 

     System.out.println("onCreate"); 

    } 

    @Override 
    public void onDateSelected(@NonNull MaterialCalendarView widget, @NonNull CalendarDay date, boolean selected) { 
     //selected is no value on logcat 
     Log.d("selected", "" + selected); 
     //It can't be show 
     Toast.makeText(this, "enterDateSelected" + date, Toast.LENGTH_SHORT).show(); 

     if (selected == true) { 
      //It can't be show 
      Toast.makeText(this, "onClick" + date, Toast.LENGTH_SHORT).show(); 
     } 
    } 

}

你是不是聽者設置爲MaterialCalendarView，解決它必須在視圖初始化後將其添加到onCreate：

calendarView.setOnDateChangedListener(this);
