android - 如何在 Android 中使用 Fragment 中的按钮调用页面？

Question

public class Menu1 extends Fragment implements View.OnClickListener {

    public static Button button_sbm;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        //returning our layout file
        //change R.layout.yourlayoutfilename for each of your fragments
       /* return inflater.inflate(R.layout.fragment_menu_1, container, false);*/
        View myView = inflater.inflate(R.layout.fragment_menu_1, container, false);
        button_sbm = (Button) myView.findViewById(R.id.button);
        button_sbm.setOnClickListener(this);
        return myView;
    }


    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        //you can set the title for your toolbar here for different fragments different titles
        getActivity().setTitle("Home");
    }



    @Override
    public void onClick(View v) {

        Intent intent = new Intent(getActivity(), MainWeb.class);
        startActivity(intent);
    }
}

如何 Intent 到 MainWeb 类..

这是我的 XML

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/yoga"
        android:layout_alignParentTop="true" />

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="30dp"
        android:text="Goto Website"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />

fragment 到 Activity 怎么办？

当我点击按钮时，它会给我一条消息

"Unfortantly App Was Stopped"

确保 MainWeb Activity 类在 AndroidManifest.xml 中被提及。

不要在 fragment 或 Activity 中创建 Button 或任何 UI 小部件的静态实例。这可能会导致内存泄漏。
