我有一个类BottomSheetFragment extends BottomSheetDialogFragment
,其中包含子片段,我从一个片段中调用它。
问题是,当我第二次调用它时,我的应用程序因Binary XML file line #69: Duplicate id 0x7f090071, tag null, or parent id 0xffffffff with another fragment
错误而崩溃。
底页类:
public class BottomSheetFragment extends BottomSheetDialogFragment {
public BottomSheetFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_bottom_sheet, container, false);
return v;
}
}
在其XML中,它包含一个子片段public class CreateNotesFragment extends android.support.v4.app.Fragment
BottomSheetFragment
类在按钮单击的另一个片段中这样调用:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_all_works, container, false);
createNew = view.findViewById(R.id.add_file_btn);
createNew.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MainActivity mainActivity = (MainActivity)getActivity();
mainActivity.showBottomSheetDialogFragment();
}
});
return view;
}
这是MainActivity
中的方法,该方法显示了底部表格:
public void showBottomSheetDialogFragment() {
bottomSheetFragment = new BottomSheetFragment();
bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
}
我假定由于某种原因第二次致电CreateNotesFragment
时,BottomSheetFragment
不再存在,但是我该如何解决?
谢谢。
fragment_bottom_sheet.xml
中的第69行
<fragment
android:id="@+id/notes_fragment"
android:name="com.app.parsec.secondary_fragments.CreateNotesFragment"
android:layout_width="0dp"
android:layout_height="wrap_content"

app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/divider9"
tools:layout="@layout/fragment_create_notes" />
以及用于确保没有ID重复的整个XML:
<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>
</FrameLayout>
我还注意到,如果我从XML中删除此片段,则可以打开BottomSheetFragment
而不会崩溃,因此问题必须出在子片段上。
BottomSheetFragment
现在看起来像这样:
public class BottomSheetFragment extends BottomSheetDialogFragment {
public BottomSheetFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_bottom_sheet, container, false);
getChildFragmentManager().beginTransaction().replace(R.id.fragment_here, new CreateNotesFragment()).commit();
return v;
}
}

答案 0 :(得分:1)
您正在尝试打开相同的片段。当前片段应被消除。 bottomSheetFragment.dismiss();
然后bottomSheetFragment.show(getSupportFragmentManager(), tag)
您可以尝试给片段加上其他标签。
public void showBottomSheetDialogFragment() {
bottomSheetFragment = new BottomSheetFragment();
bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
}
编辑:
此错误发生在布局中已定义的嵌套片段上,请尝试从XML布局中删除您的片段,然后将其替换为FrameLayout,然后在代码中动态实例化您的片段。
答案 1 :(得分:0)
您是在YourFragment的XML文件中调用片段标记,基本上,将底部工作表添加到片段是错误的方法。这是您可以执行的方法:
在botton上调用此方法,请单击:
callToGuideShareDialog();
在此方法内为底部的工作表视图填充
private void callToGuideShareDialog() {
final View viewBottom = DataBindingUtil.inflate(getLayoutInflater(), R.layout.------, null, false).getRoot();
ImageView imageView = viewBottom.findViewById(R.id.img_size_guide_share);
TextView textViewMsg = viewBottom.findViewById(R.id.----);
viewBottom.findViewById(R.id.-----).setOnClickListener(this);
TextView textViewMeasurement = viewBottom.findViewById(R.id.----);
sheetDialog = new BottomSheetDialog(context);
sheetDialog.setContentView(viewBottom);
viewBottom.post(new Runnable() {
@Override
public void run() {
BottomSheetBehavior mBehavior = BottomSheetBehavior.from((View) viewBottom.getParent());
mBehavior.setPeekHeight(viewBottom.getHeight());
}
});
if (sheetDialog != null)
sheetDialog.show();
}
