        final View rootView = inflater.inflate(R.layout.fragment_budget, container,false);

        ChangeBudgetBtn = (Button) rootView.findViewById(R.id.ChangeBudgetBtn);

        ChangeBudgetBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(v.getContext(),BudgetEdit.class));
        }
    });
    return rootView;
}
}

Answer 1

替换此行

final View rootView = inflater.inflate(R.layout.fragment_budget, false);

通过以下行

final View rootView = inflater.inflate(R.layout.fragment_budget, container, false);

因为您忘记添加容器参数

应用程序关闭，没有任何点击按钮的提示
