我想创建一个按钮，以调用viewpager中加载的号码

Question

这是“入职”视图。如图像[1]所示。当我滑动另一个项目时也会显示。我在入职活动布局中也做了按钮。现在，我要按下按钮以拨打与所示项目对应的电话号码。如何根据入职项目从数组中获取数据？

private OnBoard_Adapter mAdapter;
private Button call;
private Button email;

ArrayList<OnBoardItem> onBoardItems = new ArrayList<>();


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

 onboard_pager = (ViewPager) findViewById(R.id.pager_introduction);

 loadData();

 mAdapter = new OnBoard_Adapter(this, onBoardItems);
 onboard_pager.setAdapter(mAdapter);
 onboard_pager.setCurrentItem(0);
 onboard_pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
     @Override
     public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

     }

     @Override
     public void onPageSelected(int position) {

     }

     @Override
     public void onPageScrollStateChanged(int state) {

     }
 });

 }


// Load data into the viewpager

public void loadData() {    int[] mobile = {R.string.pg_phy_mobile1,
         R.string.pg_phy_mobile2,
         R.string.pg_phy_mobile3,
         R.string.pg_phy_mobile4,
         R.string.pg_phy_mobile5,
         R.string.pg_phy_mobile6,
         R.string.pg_phy_mobile7,
         R.string.pg_phy_mobile8,};
 int[] email = {R.string.pg_phy_email1,
         R.string.pg_phy_email2,
         R.string.pg_phy_email3,
         R.string.pg_phy_email4,
         R.string.pg_phy_email5,
         R.string.pg_phy_email6,
         R.string.pg_phy_email7,
         R.string.pg_phy_email8};
 int[] imageId = {R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar,
         R.drawable.avatar};


 for (int i = 0; i < imageId.length; i++) {
     OnBoardItem item = new OnBoardItem();
     item.setImageID(imageId[i]);
     item.setMobile(getResources().getString(mobile[i]));
     item.setEmail(getResources().getString(email[i]));

     onBoardItems.add(item);
 }
 }
}
