Question

我在FragmentA类中创建了一个GridView菜单，并且我创建了一个单独的Common_Fragment类，它包含两个ImageView。现在我想在FragmentA类和其他Fragment中重用那些Common_Fragment视图。我怎么能这样做？

＆＃13;

My FragmentA class

public class FragmentA extends Fragment {

	public FragmentA() {
		// Required empty public constructor
	}

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		// Inflate the layout for this fragment
		View view = inflater.inflate(R.layout.fragment_a, container, false);
		
		CommonFragment fragment = new CommonFragment();
		FragmentManager manager = getFragmentManager();
		FragmentTransaction transaction = manager.beginTransaction();
		transaction.add(R.id.dynamicFragmentLayout, fragment);
		transaction.commit();
		getFragmentManager().beginTransaction().replace(R.id.dynamicFragmentLayout, new Fragment()).commit();

	

		return view;
	}

}

＆＃13;

Common_Fragment Class

public class CommonFragment extends Fragment {
	ImageView imageView1,imageview2;
	
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {

		View view = inflater.inflate(R.layout.common_fragment,
				container, false);
		
		imageView1 = (ImageView) view.findViewById(R.id.imageView1);
        imageView2 = (ImageView) view.findViewById(R.id.imageView2);
	
		
		return view;

}
}

＆＃13;

fragment_a.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dynamicFragmentLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:layout_marginTop="20dp" >

    <GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="90dp"
        android:gravity="center"
        android:horizontalSpacing="10dp"
        android:numColumns="auto_fit"
        android:stretchMode="columnWidth"
        android:verticalSpacing="10dp" />

</LinearLayout>

＆＃13;

common_fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/white"
    android:orientation="vertical"
    android:id="@+id/dynamicFragmentLayout" >

    <RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/black" 
        >

        <ImageButton
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:background="@drawable/ic_launcher" />

        <ImageButton
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:background="@drawable/ic_launcher" />
    </RelativeLayout>

</LinearLayout>

＆＃13;

我在FragmentB中使用了这段代码

＆＃13;

This is my FragmentB Class

public class FragmentB extends Fragment {

	public FragmentB() {
		// Required empty public constructor
	}

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		// Inflate the layout for this fragment
		return inflater.inflate(R.layout.fragment_b, container, false);
	
		CommonFragment fragment = new CommonFragment();
		FragmentManager manager = getFragmentManager();
		FragmentTransaction transaction = manager.beginTransaction();
		transaction.add(R.id.dynamicFragmentLayout, fragment);
		transaction.commit();
		getFragmentManager().beginTransaction().replace(R.id.container,new CommonFragment()).commit();
	}

}

在FragmentA的布局xml中创建一个容器，并将common_fragment加载到FragmentA。

在fragment_a.xml中

<FrameLayout
            android:id="@+id/container"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"></FrameLayout>
<GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        .........
 />

在FragmentA.java

中

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_a, container, false);
         //Add the fragment
         getChildFragmentManager().beginTransaction().add(new             CommonFragment(),R.id.container).commit();        
          //Your code.  
    }

如何在其他片段类中重用常见的片段视图？
