按钮单击在片段中不起作用

Question

我想在片段按钮点击时显示 activity_main。

我的代码有问题吗？

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    myView = inflater.inflate(R.layout.splash, container, false);

   Button smart1 = (Button) myView.findViewById(R.id.smart1);
    smart1.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v){
           getActivity().onBackPressed();

        }

    });


    return myView;
}

按钮不工作。它只是停留在同一页面上，没有任何反应。

public class Splash extends Fragment {

    View myView;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        myView = inflater.inflate(R.layout.splash, container, false);

        return myView;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        Button smart1 = (Button) view.findViewById(R.id.smart1);
        smart1.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
                getActivity().onBackPressed();

        }

        });


    }
}

这是 Splash.java，奇怪的是为什么按钮不起作用。提前谢谢你。

这样试试

@Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

    Button smart1 = (Button) view.findViewById(R.id.smart1);
    smart1.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v){
       getActivity().onBackPressed();

    }

});
