要实现Android日历视图与事件和日程视图库,可以使用Android提供的CalendarContract和CalendarProvider API来与设备上的日历数据进行交互。以下是一个简单的示例代码,演示了如何使用这些API来获取日历事件和日程,并在日历视图和日程视图中显示它们。
然后,在app级别的build.gradle文件中添加以下依赖项:
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
然后,在CalendarActivity.java文件中添加以下代码:
import android.database.Cursor;
import android.provider.CalendarContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
public class CalendarActivity extends AppCompatActivity {
private RecyclerView calendarRecyclerView;
private CalendarAdapter calendarAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calendar);
calendarRecyclerView = findViewById(R.id.calendarRecyclerView);
calendarRecyclerView.setLayoutManager(new LinearLayoutManager(this));
calendarAdapter = new CalendarAdapter(getCalendarEvents());
calendarRecyclerView.setAdapter(calendarAdapter);
}
private Cursor getCalendarEvents() {
// 查询日历事件
Cursor cursor = getContentResolver().query(
CalendarContract.Events.CONTENT_URI,
null,
null,
null,
null
);
return cursor;
}
}
然后,在ScheduleActivity.java文件中添加以下代码:
import android.database.Cursor;
import android.provider.CalendarContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
public class ScheduleActivity extends AppCompatActivity {
private RecyclerView scheduleRecyclerView;
private ScheduleAdapter scheduleAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_schedule);
scheduleRecyclerView = findViewById(R.id.scheduleRecyclerView);
scheduleRecyclerView.setLayoutManager(new LinearLayoutManager(this));
scheduleAdapter = new ScheduleAdapter(getCalendarEvents());
scheduleRecyclerView.setAdapter(scheduleAdapter);
}
private Cursor getCalendarEvents() {
// 查询日程事件
Cursor cursor = getContentResolver().query(
CalendarContract.Instances.CONTENT_URI,
null,
null,
null,
null
);
return cursor;
}
}
import android.database.Cursor;
import android.provider.CalendarContract;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class CalendarAdapter extends RecyclerView.Adapter {
private Cursor cursor;
public CalendarAdapter(Cursor cursor) {
this.cursor = cursor;
}
@NonNull
@Override
public EventViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R
