在我的應用程序中，我使用此庫 https://github.com/DmitryMalkovich/circular-with-floating-action-button 來實現帶浮動操作按鈕的進度條。它的工作活動，但是當我在我的片段的佈局進度條中包含此佈局不顯示。 這裏是我的代碼更好的解釋 請指導我在哪裏我錯了 任何幫助將不勝感激。 customlayout.xml進度條不顯示在片段[ANDROID]

我隱藏和顯示，當我得到serivice數據運行customlayout.xml的父佈局，前服務呼叫我用查看.VISIBLE和售後服務電話我跟它隱藏View.GONE
修訂 Java代碼
片段
public class MyFragment extends Fragment {
private Context context;
//root view of layout
View rootView;
private static final String ARG_PARAM1 = "Class";
private String screen_title;
private String URL = "";
public MyFragment() {
// Required empty public constructor
}
public static MyFragment newInstance(String param1) {
MyFragmentfragment = new MyFragment();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = getActivity();
if (getArguments() != null) {
screen_title = getArguments().getString(ARG_PARAM1);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
rootView = inflater.inflate(R.layout.fragmentlayout, container, false);
//find views by ids
getData();
return rootView;
}
private void getData() {
CustomClass.getInstance(context, rootView).show();
//service call
//on getting response from serivce (have implemented a listener here)
CustomClass.getInstance(context, rootView).hide(); }
@Override
public void onAttach(Context context) {
super.onAttach(context);
}
@Override
public void onDetach() {
super.onDetach();
}
CustomClass
public class CustomClass {

private static CustomClass custom;
private CustomClass (Context context) {
findViewsById(context);

custom.setPColor(context);
return custom;
}
private void setPColor(Context context) {
if (mProgressBar != null)
mProgressBar.getIndeterminateDrawable().setColorFilter(ContextCompat.getColor(context, R.color.bluecolor), android.graphics.PorterDuff.Mode.MULTIPLY);
}
private void findViewsById(View view) {
if (view != null) {
mProgressBar = (ProgressBar) view.findViewById(R.id.custom_progressbar);
mFab = (FloatingActionButton) view.findViewById(R.id.custom_floatingActionButton);
parentLayout = (RelativeLayout) view.findViewById(R.id.rl_progress_fab_container);
}
}
private void findViewsById(Context context) {

mFab = (FloatingActionButton) activity.findViewById(R.id.custom_floatingActionButton);
parentLayout = (RelativeLayout) activity.findViewById(R.id.rl_progress_fab_container);
}
}
public void show() {
if (custom.parentLayout != null)
custom.parentLayout.setVisibility(View.VISIBLE);
}
public void hide() {
if (custom.parentLayout != null)
custom.parentLayout.setVisibility(View.GONE);
}
另外補充服務代碼，你在哪裏隱藏或可見的進度。 –
更改FAB和進度條的順序 –
把你的java代碼放在這裏 –
