Question

我正在尝试使用以下代码从嵌套片段中启动一个新活动：

Intent rateIntent = new Intent(context, RateServiceActivity.class);
getActivity().startActivity(rateIntent);

我收到以下错误：

java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.serve.learn/com.serve.learn.MyOrdersPage.RateServiceActivity}: 
android.view.InflateException: Binary XML file line #31: Error inflating class fragment

我已尝试过在线提供的所有解决方案，但没有运气。此外，我认为此错误特定于嵌套片段方案，而不是其他帖子中提到的一般错误。

我的xml文件应该没有任何问题，因为到目前为止我没有遇到任何问题。只有当我尝试从嵌套片段中启动新活动时，我才会收到此错误。

无论如何，这是我activity_main.xml中的代码（从第31行开始）：

<fragment
    android:id="@+id/navigation_drawer"
    android:name="com.serve.learn.MainActivityPage.NavigationDrawerFragment"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    tools:layout="@layout/fragment_navigation_drawer" />

这是嵌套的片段代码：

package com.serve.learn.MyOrdersPage;

import com.serve.learn.R;

import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

public class Fragment_Fragment_UpcomingOrders extends Fragment implements OnClickListener{

TextView order1Details, order1, order2Details, order2, order3Details, order3;
View rootView;
Button callButton, rateButton;
Context context;

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        rootView = inflater.inflate(R.layout.fragment_fragment_upcoming_orders, container, false);
        context = rootView.getContext();
        order1Details = (TextView) rootView.findViewById(R.id.order1Details);
        order1Details.setVisibility(View.GONE);
        order1 = (TextView) rootView.findViewById(R.id.order1);
        order1.setOnClickListener(this);
        order2Details = (TextView) rootView.findViewById(R.id.order2Details);
        order2Details.setVisibility(View.GONE);
        order2 = (TextView) rootView.findViewById(R.id.order2);
        order2.setOnClickListener(this);
        order3Details = (TextView) rootView.findViewById(R.id.order3Details);
        order3Details.setVisibility(View.GONE);
        order3 = (TextView) rootView.findViewById(R.id.order3);
        order3.setOnClickListener(this);
        callButton = (Button) rootView.findViewById(R.id.callButton);
        callButton.setOnClickListener(this);
        rateButton = (Button) rootView.findViewById(R.id.rateButton);
        rateButton.setOnClickListener(this);
        return rootView;
    }

 @Override
public void onCreate(Bundle savedInstanceState)
 {
     super.onCreate(savedInstanceState);
 }

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch(v.getId())
    {
    case R.id.order1 :  order1Details.setVisibility( order1Details.isShown()? View.GONE:View.VISIBLE );
                        break;
    case R.id.order2 :  order2Details.setVisibility( order2Details.isShown()? View.GONE:View.VISIBLE );
                        break;
    case R.id.order3 :  order3Details.setVisibility( order3Details.isShown()? View.GONE:View.VISIBLE );
                        break;
    case R.id.callButton :  Intent callIntent = new Intent(Intent.ACTION_CALL);
                            callIntent.setData(Uri.parse("tel:123456789"));
                            startActivity(callIntent);
                            break;
    case R.id.rateButton :  Intent rateIntent = new Intent(context, RateServiceActivity.class);
                            getActivity().startActivity(rateIntent);
                            break;
    }
}

}

fragment_fragment_upcoming_orders.xml的代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" 
android:layout_gravity="center_vertical|center_horizontal" >

有关我可能出错的地方的任何建议吗？
