如何使用一个按钮在我的项目打开一个xml文件 [英] How can i use a button to open an xml file in my project

问题描述

我想开在我的项目上的按钮，一个XML文件，点击这是我的code可能有人请建议我如何能做到这一点。我无法做到这一点的一个我没有使用onclicklistener了。此外，我如何让第二个片段的默认片段，这样，当我从左至右滑动我可以查看的第一个片段。

I want to open an xml file in my project on button click this is my code could somebody please suggest me how can i do it. I'm unable to do it the one i did was using onclicklistener. Also how can i make the second fragment the default fragment so that when i slide from left to right i can view the first fragment.

public class FragmentFirstPage extends Fragment {

View root;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle bundle){

    root = inflater.inflate(R.layout.fragment_page1, container, false);

            //If you want to retrieve a textview inside fragment_page1.xml for example, you shall do:
            //TextView text = (TextView) root.findViewById(R.id.blablabla); 


    Button bt = (Button) root.findViewById(R.id.button1);

  //  final ViewPager viewPager = (ViewPager) getActivity().findViewById (R.id.activity_main_viewpager);

    bt.setOnClickListener(new View.OnClickListener() {

         @Override
          public void onClick (View v){
             Intent i=new Intent(fragment_page1.this, SplashActivity.class);
             startActivity(i);

         } 
    });
    return root;
}

给我的错误
意图I =新意图（fragment_page1.this，SplashActivity.class）;
说fragment_page1不能被解析为一个类型，否则

Gives me error at Intent i=new Intent(fragment_page1.this, SplashActivity.class); says fragment_page1 cannot be resolved to a type or else

意图I =新意图（FragmentFirstPage.this，SplashActivity.class）;
说，在这条线多个标记
     - 构造意图（FragmentFirstPage，类）
     未定义

Intent i=new Intent(FragmentFirstPage.this, SplashActivity.class); says Multiple markers at this line - The constructor Intent(FragmentFirstPage, Class) is undefined

推荐答案

您有FragmentFirstPage和FragmentSecondPage，你可能有fragment_page1.xml和fragment_page2.xml

You have FragmentFirstPage and FragmentSecondPage, you may have fragment_page1.xml and fragment_page2.xml

PS：删除任何Android：onclick属性

PS: remove any android:onClick attribute

您FirstFragmentPage内部，对onCreateView（），添加以下，如果你的按钮上fragment_page1.xml

Inside your FirstFragmentPage, on onCreateView (), , add the following if your button is on fragment_page1.xml

Button bt = (Button) root.findViewById(R.id.your_button_id);

ViewPager viewPager = (ViewPager) getActivity().findViewById (R.id.your_viewpager_id ();

bt.setOnClickListener(new View.onClickListener (){

     @Override
      public void onClick (View v){

      viewPager.setCurrentItem (viewPager.getCurrentItem() + 1); //or -1 to go previous

      } 

}
