Question

我开始使用两个简单按钮来构建我的应用程序，每个按钮进入一个不同的活动，第一个进入并滑动带有片段的Tab活动，第二个进入空白活动。问题是当我在手机中运行该应用程序时，仅单击第一个按钮便崩溃了，我签入了logcat并说了

滑块活动中的标签

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


        View rootView =null;
        switch (getArguments().getInt(ARG_SECTION_NUMBER)){
            case 1:
                ///
                rootView = inflater.inflate(R.layout.fragment_main2, container, false);
                break;
            case 2:
                ///
                rootView = inflater.inflate(R.layout.fragment_fragment_main3, container, false);
                break;
        }

主要活动

//method open act open chest
    butchest=(Button) findViewById(R.id.but1);
    butchest.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openActivitychest();
        }
    });
    //
    //method open act class
    butclass=(Button) findViewById(R.id.but2);
    butclass.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openActivityclass();
        }
    });
    //
}
//Open act open chest
public void openActivitychest(){
    Intent intent1 = new Intent(this, Main2Activity.class);
    startActivity(intent1);
}
//
//Open act class
public void openActivityclass(){
    Intent intent2 =new Intent(this,ActivityClassguides.class);
    startActivity(intent2);

我希望有人能帮助我解决这个问题

谢谢：）
