谢谢你们D假设您的活动xml中有一个TabLayout，您需要在
mviewpage.setAdapter（msectionspageradopter）之后插入此代码：
我知道怎么做了
我刚刚在我的onCreateView
if (getArguments().getInt(ARG_SECTION_NUMBER) == 1){
View rootView = inflater.inflate(R.layout.content_ownerhome, container, false);
return rootView;
}
else if(getArguments().getInt(ARG_SECTION_NUMBER) == 2){
View rootView = inflater.inflate(R.layout.content_insert, container, false);
return rootView;
}
else if(getArguments().getInt(ARG_SECTION_NUMBER) == 3){
View rootView = inflater.inflate(R.layout.content_detail, container, false);
return rootView;
}
else {
View rootView = inflater.inflate(R.layout.fragment_owner_tabs, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
可能重复的
if (getArguments().getInt(ARG_SECTION_NUMBER) == 1){
View rootView = inflater.inflate(R.layout.content_ownerhome, container, false);
return rootView;
}
else if(getArguments().getInt(ARG_SECTION_NUMBER) == 2){
View rootView = inflater.inflate(R.layout.content_insert, container, false);
return rootView;
}
else if(getArguments().getInt(ARG_SECTION_NUMBER) == 3){
View rootView = inflater.inflate(R.layout.content_detail, container, false);
return rootView;
}
else {
View rootView = inflater.inflate(R.layout.fragment_owner_tabs, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
