以下是我對我的日曆爲什麼導航抽屜中的日曆不工作?
public class Calender extends android.support.v4.app.Fragment {
CalendarView calendar;
public Calender() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View fragmentRootView = inflater.inflate(R.layout.fragment_calender, container, false);
calendar = (CalendarView) fragmentRootView.findViewById(R.id.calendar);
calendar.setShowWeekNumber(false);
calendar.setFirstDayOfWeek(2);
calendar.setSelectedWeekBackgroundColor(getResources().getColor(R.color.green));
calendar.setUnfocusedMonthDateColor(getResources().getColor(R.color.transparent));
calendar.setWeekSeparatorLineColor(getResources().getColor(R.color.transparent));
calendar.setSelectedDateVerticalBar(R.color.darkgreen);
calendar.setOnDateChangeListener(new OnDateChangeListener() {
@Override
public void onSelectedDayChange(CalendarView view, int year, int month, int day) {
Toast.makeText(getApplicationContext(), day + "/" + month + "/" + year, Toast.LENGTH_LONG).show();
}
});
return fragmentRootView;
}
}
代碼有一個在getApplicationContext(), 錯誤,以下是MainActivity.java代碼,即時試圖以打開創建一個片段從導航抽屜中的日曆
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem item) {
switch (item.getItemId())
{
case R.id.calendar:
fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.main_container, new Calender());
fragmentTransaction.commit();
getSupportActionBar().setTitle("Calender");
item.setChecked(true);
break;
// drawer.closeDrawers();
}
return true;
}
});
我也爲日曆創建了一個新的xml文件,並且在主xml中使用了框架佈局。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:background="@color/colorPrimary"
android:minHeight="?attr/actionBarSize"

</RelativeLayout>
<FrameLayout

<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigation_header"
app:menu="@menu/navigation_item">
</android.support.design.widget.NavigationView>
沒有它不工作,我認爲這可能是由於容器或框架佈局,請你看看代碼 – Mohendra
你reveive什麼樣的錯誤? –
不完全錯誤,它只是當我點擊導航抽屜中的日曆,它什麼也沒有, – Mohendra
