Android图片滑块文字更改

Question

我使用this进行了Android图片滑动。它工作正常。但我需要一些定制。我需要文字和按钮贝娄图像和文字应根据图像滑动更改。并且文本和按钮不应该滑动。

我做了什么，我在fragment_page上放了两个文本视图和按钮。

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:background="@drawable/background"
android:weightSum="1">

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="wrap_content"
    android:layout_height="217dp"
    android:layout_weight="0.71">
</android.support.v4.view.ViewPager>

<TextView
    style="@style/bigFont"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="Large Text"
    android:id="@+id/textBold"
    android:layout_marginTop="20dp"
    android:textColor="@color/text_color"
    android:layout_centerHorizontal="true"/>

<TextView
    style="@style/smallFont"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:text="Medium Text"
    android:id="@+id/textsmall"
    android:layout_marginTop="20dp"
    android:layout_below="@+id/textBold"
    android:textColor="@color/text_color"
    android:layout_centerHorizontal="true"/>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="REGISTER NOW"
    android:id="@+id/button2"
    android:background="@drawable/button_design"
    android:textColor="@color/text_color"
    android:padding="@dimen/abc_action_bar_content_inset_material"
    android:layout_below="@+id/textsmall"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="60dp" />

</LinearLayout>

这是我的班级。

                break;
            case 3:
               // boldTxt.setText(R.string.helpline);
              //  smallTxt.setText(R.string.call_call_center);
                break;
        }
    }

    static SwipeFragment newInstance(int position) {
        SwipeFragment swipeFragment = new SwipeFragment();
        Bundle bundle = new Bundle();
        bundle.putInt("position", position);
        swipeFragment.setArguments(bundle);
        return swipeFragment;
    }


}

}

检查settext方法。在这里我尝试更改文本，但问题是这个上下文是在另一个类中，它是静态的，所以我无法改变它。我怎么能让它工作？
