为什么片段不起作用

Question

请帮忙。怎么了？错误的原因是什么，我怎么解决它？谢谢你的帮助！

> java.lang.RuntimeException: Unable to start activity 
> ComponentInfo{com.example.interviewhelpers/com.example.interviewhelpers.Dashboard}: 
> android.view.InflateException: Binary XML file line #192: Error 
> inflating class fragment 


Caused by: android.view.InflateException: Binary XML file line #192: Error inflating class fragment 

这是我的代码：主类...

public class Dashboard extends Activity implements OnClickListener { 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_dashboard); 

activity_dashboard ...有更多的元素和设计，而这：

<fragment 
     android:id="@+id/listFragment" 
     android:layout_width="150dip" 
     android:layout_height="match_parent" 
     android:name="com.example.interviewhelpers.ClientDetailActivity" ></fragment> 

而且......

package com.example.interviewhelpers; 

    import android.os.Bundle; 
    import android.support.v4.app.FragmentActivity; 
    import android.view.LayoutInflater; 
    import android.view.View; 
    import android.view.ViewGroup; 
    import android.widget.TextView; 

    public class ClientDetailActivity extends FragmentActivity { 

     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      View view = inflater.inflate(R.layout.cliente_detailed, container, false); 
      TextView textView = (TextView) view.findViewById(R.id.detailsText); 
      return view; 
     } 

    }

（总是尝试使用支持库a你正在做的） 第一个： 1.应该使用FragmentActivity和NO活动 2.应该使用片段到你将要使用的子组件。 3.在onCreateView上的片段上只需执行Inflate 4.在片段上使用onViewCreated来查找TextView。 样品： //这是活动

public class MainActivity extends FragmentActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    }  
} 

//这是layout.activity_main

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <fragment 
     android:name="com.example.fragmentapp.ChildFragment" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_above="@+id/textView1" 
     android:layout_alignParentTop="true" /> 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:padding="@dimen/padding_medium" 
     android:text="@string/hello_world" 
     tools:context=".MainActivity" /> 

</RelativeLayout> 

//这是要显示

public class ChildFragment extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     return inflater.inflate(R.layout.child_frag, null); 
    } 

    @Override 
    public void onViewCreated(View view, Bundle savedInstanceState) { 
     super.onViewCreated(view, savedInstanceState); 
     TextView tvText = (TextView)view.findViewById(R.id.textView1); 
     tvText.setText("Found!"); 
    } 
} 

的片段//这是碎片布局的布局.child_fragment

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="TextView" /> 

</LinearLayout>
