Question

我正在尝试在片段中创建一个caldroid日历。

但是我得到一个错误我做错了什么？我有一个滑动菜单（不是绝对），它似乎导致了我认为的错误。

我已经包含了从下面的主片段中调用的xml和类以及log cat。有谁知道我做错了什么？

public class PM_Fragment extends Fragment{
    private FragmentActivity myContext;

    @Override
    public void onAttach(Activity activity) {
        myContext=(FragmentActivity) activity;
        super.onAttach(activity);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

       View rootView = inflater.inflate(R.layout.pm_fragment, container, false);

        CaldroidFragment caldroidFragment = new CaldroidFragment();
        Bundle args = new Bundle();
        Calendar cal = Calendar.getInstance();
        args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
        args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
        caldroidFragment.setArguments(args);

        FragmentManager fragManager = myContext.getSupportFragmentManager();

        android.support.v4.app.FragmentTransaction t = fragManager.beginTransaction();
        t.replace(R.id.pm_fragment, caldroidFragment);
        t.commit();

    return rootView;
    }

XML：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_marginLeft="@dimen/activity_horizontal_margin"
    android:layout_marginRight="@dimen/activity_horizontal_margin"
    android:layout_marginTop="@dimen/activity_vertical_margin"
    android:layout_marginBottom="@dimen/activity_vertical_margin" >

<fragment
   android:name="com.projectcaruso.naturalfamilyplaning.PM_Fragment"
   android:id="@+id/pm_fragment"
   android:layout_width="0dp"
   android:layout_height="match_parent" />


</RelativeLayout>

Answer 1

我正在检查git上的示例，他们为该示例使用了linearLayout而不是

您的xml布局：

<fragment
   android:name="com.projectcaruso.naturalfamilyplaning.PM_Fragment"
   android:id="@+id/pm_fragment"
   android:layout_width="0dp"
   android:layout_height="match_parent" />

Caldroid样本布局：

<LinearLayout
        android:id="@+id/calendar1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
</LinearLayout>
