android - 无法使用 github 项目中的 material-calendarview 设置 onClick

Question

我引用了 https://github.com/prolificinteractive/material-calendarview

我实现了 OnDateSelectedListener 和 @Override onDateSelected ，但是当我点击日历上的任何一天时没有任何工作。

为什么？

任何人都可以教我我错过了什么？提前致谢

毕业项目:

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

布局 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>

我的日历类:

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();
        }
    }

}

您没有为 MaterialCalendarView 设置监听器，要解决这个问题，您必须在 View 初始化后将其添加到 onCreate:

calendarView.setOnDateChangedListener(this);
