我希望你能帮我解决一个问题。我试图谷歌它，并通过这里的主题，但无法找到答案。在DialogFragment中显示ConstraintLayout
我最近将布局更改为ConstraintLayouts，至今为止这一切都非常顺利。然而，我的问题是我有一些DialogFragments显示LinearLayout，当我将其更改为ConstraintLayout我只显示一个褪色叠加，但没有布局中的元素。如果我将宽度和高度硬编码为100dp之类的东西，它将显示该区域。当我尝试match_parent或任何其他组合时，同样的问题适用。我也尝试将高度和宽度设置为设备的高度和宽度，但仍然没有运气。
在onCreateView我CreateWeddingMetadataFragment我有：
createButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "Show message dialog");
FragmentManager fm = getFragmentManager();
CreateWeddingMetadataDialogFragment welcomeMessageDialog = new CreateWeddingMetadataDialogFragment();
welcomeMessageDialog.show(fm, "metadate_fragment_dialog");
welcomeMessageDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
}
});
在我CreateWeddingMetadataFragmentDialog我有：
public class CreateWeddingMetadataDialogFragment extends DialogFragment{
private static final String TAG = CreateWeddingMetadataDialogFragment.class.getSimpleName();
public Button setupNow, setupLater;
public TextView mTest;
public ConstraintLayout parentLayout;
private DialogInterface.OnDismissListener onDismissListener;
public void setOnDismissListener(DialogInterface.OnDismissListener onDismissListener) {
this.onDismissListener = onDismissListener;
}
@Override
public void onDismiss(DialogInterface dialog) {
super.onDismiss(dialog);
if (onDismissListener != null) {
onDismissListener.onDismiss(dialog);
}
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "I was called");
}
public CreateWeddingMetadataDialogFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.create_welcome_message_view, container);
setupNow = (Button) view.findViewById(R.id.setupNowButton);
setupLater = (Button) view.findViewById(R.id.setupLaterButton);
mTest = (TextView) view.findViewById(R.id.welcomeMessageTitle);
parentLayout = (ConstraintLayout) view.findViewById(R.id.clWelcomeMessage);
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
int width = displayMetrics.widthPixels;
int height = displayMetrics.heightPixels;
parentLayout.setMinimumWidth(width);
parentLayout.setMinimumHeight(height);
mTest.setText("Test");
Log.d(TAG, "I was called onCreateView" + mTest);
setupNow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//Go to metadate page (Hide this dialog)
}
});
setupLater.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//Go to signin page and create the wedding
}
});
return view;
}
}
这就是我目前的尝试将其设置到设备的尺寸。

如果您需要任何额外的信息，让我知道，在此先感谢。
我确定这是一个ConstraintLayout错误。您可以将您的布局封装在FrameLayout中，并为您的ConstraintLayout设置固定大小 - 将显示视图。 – Outofdate
