如何將我的fab放在我的片段上？請幫助我得到錯誤，如。如何將FloatingActionButton放入片段？

android.view.InflateException：二進制XML文件行＃13：錯誤充氣類片段

在我的片段acticity

。那麼這裏是我的代碼。

井的問題是在getActivity().setContentView(R.layout.activity_ownerhome);

#ownerhome.java 

public class ownerhome extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_ownerhome); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    } 

}

ownerhomeFragment.java

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.fragment_owner, container, false); 


    ImageLoader.getInstance().init(UILConfig.config(getActivity())); 
    lvCars = (ListView) v.findViewById(R.id.lvOnwer); 

    pref = getActivity().getSharedPreferences("Login.conf", Context.MODE_PRIVATE); 
    Log.d(TAG, pref.getString("username", "")); 
    Log.d(TAG, pref.getString("password", "")); 


    PostResponseAsyncTask taskRead = new PostResponseAsyncTask(getActivity(), this); 
    tvUser = (TextView) v.findViewById(R.id.tvUser); 
    tvUser.setText("Hello! "+pref.getString("username", "")); 

    taskRead.execute("http://carkila.esy.es/user.php?owner="+pref.getString("username", "")); 

    FloatingActionButton fab = (FloatingActionButton) v.findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent in = new Intent(getActivity(), InsertActivity.class); 
      startActivity(in); 
     } 
    }); 
    registerForContextMenu(lvCars); 
    return v; 
}

你可以發佈你的整個堆棧跟蹤？ –

@GlennPorter - 發佈更新的先生。感謝：D –

嘗試更改getActivity（）。setContentView（R.layout.activity_ownerhome）;從你的片段類的onCreateView，並膨脹充氣適當的佈局xml文件 – darwin

您已經在您的activity_ownerhome.xml中添加了浮動操作按鈕，並且您正在ownerhomeFragment.java中初始化它。

因此，將您的FloatingActionButton添加到fragmentownerhome中。xml本身就像這樣

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context="com.example.kun.carkila.ownerhome" 
    tools:showIn="@layout/activity_ownerhome"> 

    <ListView 
    android:layout_width="match_parent" 
    android:layout_height="450sp" 
    android:id="@+id/lvOnwer" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:layout_alignParentBottom="true" /> 

    <TextView 
    android:text="TextView" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:layout_marginTop="24dp" 
    android:textSize="30sp" 
    android:textColor="@color/colorPrimaryDark" 
    android:id="@+id/tvUser" /> 

    <android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom|end" 
    android:layout_margin="@dimen/fab_margin" 
    android:src="@drawable/plus" /> 
</RelativeLayout>

並從您的activity_ownerhome.xml文件中移除FloatingActionButton。

我不認爲這是問題所在。問題在於他如何膨脹片段。看到我上面的答案。 – amitairos

其實這個工程。但晶圓廠在左上角。不在底部。 –

現在沒事了。謝謝你，先生！ –

的問題是不是與FAB，它與你如何誇大你的看法。
片段中替換此代碼：

View v = super.onCreateView(inflater, container, savedInstanceState); 
getActivity().setContentView(R.layout.activity_ownerhome);

有了這個：

var v = inflater.inflate(R.layout.{your fragment xml}, container, false);

，並刪除此：

<fragment 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:name="com.example.kun.carkila.ownerFragment" 
android:id="@+id/ownerhomeFragment"/>

你應該定義你希望你的片段XML來看，然後使用代碼inflater.inflate...對它進行膨脹，然後放入您的片段xml，就像我上面所寫的那樣。

更新：
而是在此的<include layout="@layout/content_ownerhome" />地方：

<FrameLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/content_frame" />

然後在您的主要活動寫這樣的代碼：你應該

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit();

而且看你的片段，如果在片段中，您正確填充了片段xml，如上所述。

當我刪除xml時，我的活動沒有任何東西。 –

我更新了我的答案。現在它應該工作。 – amitairos
