我想在Android Studio中共享ViewFlipper的当前图像那么如何共享当前的翻转图像

这里是代码

  <ViewFlipper
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/viewFlipper">

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="fitXY"
        android:id="@+id/imageView"
        android:src="@drawable/love_one"></ImageView>

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="fitXY"
        android:id="@+id/imageView2"
        android:src="@drawable/love_two"></ImageView>

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="fitXY"
        android:id="@+id/imageView3"
        android:src="@drawable/love_there"></ImageView>

</ViewFlipper>

<Button
android:id="@+id/next"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"/>
<Button
    android:id="@+id/share"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Share"
    android:onClick="buttonshare" />
<Button
    android:id="@+id/previous"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Prev"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentBottom="true"
    android:layout_alignTop="@+id/next"/>

.java代码

public class Main2Activity extends AppCompatActivity implements View.OnClickListener {
    ViewFlipper viewFlipper;
    Button next;
    Button previous;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        viewFlipper = (ViewFlipper)findViewById(R.id.viewFlipper);
        next = (Button) findViewById(R.id.next);
        previous = (Button) findViewById(R.id.previous);

        next.setOnClickListener(this);
        previous.setOnClickListener(this);
    }
    @Override
    public void onClick(View v) {
        if (v == next) {
            viewFlipper.showNext();
        }
        else if (v == previous) {
            viewFlipper.showPrevious();
        }
    }

    public void buttonshare(View view)
    {
        final Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("image/jpg");
        final File photoFile = new File(getFilesDir(), "foo.jpg");
        shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(photoFile));
        startActivity(Intent.createChooser(shareIntent, "Share image using"));
    }

}

我面临着如何为所有ViewFliper图像创建共享选项的问题。
