我正在使用Viewpager在3个片段之间切换,一切正常,除了刷新第二个标签(或片段).在此选项卡中,我有一张图片,一些静态Textviews,一些动态TextView和一些EditText字段.
每次选择第二个选项卡时,都会在所有动态字段上调用setText(). TextView组件和微调器正在刷新并更新其内容,但EditText元素则不会.
我不明白为什么这些字段没有更新.更换标签后,我在TabsAdapter中调用notifiyDataSetChanged().每次我更改选项卡时都会调用onViewCreated().在第二个片段的onViewCreated()中,我正在更改元素的内容.
那是我片段的代码:
@Override public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) { hA = (HelloAndroidActivity)this.getSherlockActivity(); appState = ((TestApplication)this.getSherlockActivity().getApplicationContext()); final PersistenceHelper pH = new PersistenceHelper(appState); m = pH.readMitarbeiter(toDisplay); // Inflate the layout for this fragment v = inflater.inflate(R.layout.detailfragment,container,false); if(m==null) { //If Mitarbeiter is empty pH.closeDB(); return v; } //Inflating Elements employeeName = (TextView)v.findViewById(R.id.employee_name); cDate = (TextView)v.findViewById(R.id.department); currentPlace = (TextView)v.findViewById(R.id.place_label); comment_text = (EditText)v.findViewById(R.id.comment_text); reachable = (EditText)v.findViewById(R.id.reachable_text); state = (Spinner)v.findViewById(R.id.spinner_state); durchwahl = (EditText)v.findViewById(R.id.durchwahl); department = (EditText)v.findViewById(R.id.department_edit); email = (EditText)v.findViewById(R.id.email_edit); img = (ImageView)v.findViewById(R.id.userPic); changeData = (Button)v.findViewById(R.id.changeButton); //Setting Elements employeeName.setText(m.getL_name()); currentPlace.setText(m.getStatus()); comment_text.setText(m.getBemerkung()); reachable.setText(m.getErreichbar()); email.setText(m.getS_name()+""); durchwahl.setText(m.getDurchwahl()+"",TextView.BufferType.EDITABLE); department.setText(m.getFunktion(),TextView.BufferType.NORMAL); //Spinner String[] values = { "Anwesend","Mittagspause","Ausser Haus","Dienstreise","Krankenstand","Zeitausgleich","Urlaub","Abwesend" }; ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(this.getSherlockActivity(),android.R.layout.simple_spinner_item,values); state.setAdapter(spinnerArrayAdapter); state.setSelection(StateMapper.returnState(m.getStatus())); //Image //....... return v; }
正如我之前提到的,我的Image,TextView和Spinner Elements正在刷新它们的内容.我还检查了所有变量的内容,除了这些EditText元素外,一切似乎都很好.如果我将EditText元素转换为TextView,则内容正在改变(在代码中但不在GUI中).让我绝望的是,EditText在我第一次设置值时刷新.
有谁有想法,我怎么能刷新我的EditText字段的内容?
解决方法
我不确定但是尝试onResume()并将文本设置为恢复状态.
或尝试
选项卡更改上的Intent.FLAG_ACTIVITY_CLEAR_TOP.
