关于ProgressBar的颜色设置，基于不同的style，设置可以自定义样式及颜色等
例如：
style -> Widget.AppCompat.ProgressBar
通过查找属性定义-> indeterminateDrawable -> progress_static_material.xml
在这个矢量的xml中可以找到其颜色配置是fillColor=“?attr/colorControlActivated”
如果只是修改颜色，最终只需要在Theme中
<item name="colorControlActivated">@color/colorAccent</item> 即可修改颜色，不需要自定义.
另基于DialogFragment的全局性Loading
public class LoadingDialogFragmentextends DialogFragment {
public static LoadingDialogFragment newInstance() {
return new LoadingDialogFragment();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
getActivity().getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);// 背景变暗.
return super.onCreateView(inflater, container, savedInstanceState);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
View v = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_loading_dialog,null);
AlertDialog dialog =new AlertDialog.Builder(getActivity())
.setView(v)
.create();
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
return dialog;
}
@Override
public void onDestroyView() {
super.onDestroyView();
getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
}
}
