二进制xml文件行＃9错误膨胀类

我知道这里有很多关于这个话题，但我似乎没有得到我的问题的根源。问题是我在MainActivity中有一个片段，当我按下操作栏溢出中的设置按钮时，我想用其他片段替换它。这很好，但如果我尝试再次按设置按钮，或返回，然后再试一次，我的应用程序将崩溃（不幸的是MyApp已停止），所以我想知道是什么问题。非常感谢，如果你能帮助我，或者如果你只是花时间阅读它，我是新来的android编程，我想了解它很多。二进制xml文件行＃9错误膨胀类

这里是堆栈跟踪，还看我MainActivity.class

package com.example.myfirstapp; 

import android.app.AlertDialog; 
import android.app.FragmentTransaction; 
import android.content.Intent; 
import android.os.Bundle; 
import android.support.v7.app.ActionBarActivity; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.EditText; 


public class MainActivity extends ActionBarActivity { 

    public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE"; 

    private FragmentOpAdv fragmentOpAdv; 
    private FragmentA fragmentA; 

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

     if(findViewById(R.id.mainact)!=null) 
     { 
      if (savedInstanceState!=null) 
      { 
       return; 
      } 
      fragmentA= new FragmentA(); 
      getSupportFragmentManager().beginTransaction().add(R.id.mainact, fragmentA).commit(); 
     } 
    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (R.id.action_search==id) 
     { 
      openSearch(); 
      return true; 
     } 
     if (R.id.action_settings==id) 
     { 
      openSettings(); 
      return true; 
     } 
     else 
     { 
      return super.onOptionsItemSelected(item); 
     } 
    } 

    /** 
    * Called when the user clicks the Settings item 
    */ 
    public void openSettings() { 
     fragmentOpAdv = new FragmentOpAdv(); 
     getSupportFragmentManager().beginTransaction().replace(R.id.mainact, fragmentOpAdv).addToBackStack(null).setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE).commit(); 
    } 

    /** 
    * Called when the user clicks the Search item 
    */ 
    public void openSearch() { 
     AlertDialog.Builder alert = new AlertDialog.Builder(this); 
     alert.setTitle("Inserte algo"); 
     alert.setMessage("Oiga en serio"); 
     alert.show(); 
    } 


    /** Called when the user clicks the Send button */ 
    public void sendMessage(View view) 
    { 
     Intent intent = new Intent(this, DisplayMessageActivity.class); 
     EditText editText = (EditText) findViewById(R.id.edit_message); 
     String message = editText.getText().toString(); 
     intent.putExtra(EXTRA_MESSAGE, message); 
     startActivity(intent); 
    } 
}

和我的片段类

package com.example.myfirstapp; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

public class FragmentOpAdv extends Fragment{ 

    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    { 
     try { 
      View view = inflater.inflate(R.layout.fragment_op_adv, container, false); 

      return view; 
     } catch (Exception e) { 
      e.printStackTrace(); 
      System.out.println(e.getMessage()); 
      return null; 
     } 

    } 
}

下面是主要活动

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/mainact" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:background="@drawable/bg" 
android:paddingTop="?attr/actionBarSize" >

看起来你的布局xml文件中有一个重复的id（第9行） - 你可以把它们粘贴在这里吗？ – 2014-09-27 23:41:44

是的，我试图检查，但我没有找到任何 – kickingnico 2014-09-27 23:47:39

OH我刚刚发现它是什么，在其他XML文件中的ID是一样的，事情是，我用旧片段作为片段的新片段，不应该我做这个？ – kickingnico 2014-09-27 23:50:10

我刚刚发现的问题是，当布局包含一个布局时，我无法将布局充气到碎片中。只有在动态添加到片段时才支持嵌套片段。

如果一切沃金同谷歌的代码，那么请查一下我的情况下，清单文件我添加地理键和地图关键，这就是为什么发生异常时，

注意 - 不要在清单文件中添加两个密钥删除地图密钥

meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="@string/google_maps_key"/>

上面的代码和添加此代码。

<meta-data 
     android:name="com.google.android.geo.API_KEY" 
     android:value="@string/auto_location"/> 

<meta-data 
     android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version"/>
