希望你能帮我解决一个问题。我已经尝试在Google上搜索并查找这里的主题，但没有找到答案。
最近我将我的布局更改为ConstraintLayouts，目前一切都很顺利。然而，我的问题是我有一些显示LinearLayout的DialogFragments，当我将其更改为ConstraintLayout时，它只显示了一个褪色的覆盖层，但没有布局中的任何元素。如果我将宽度和高度硬编码为100dp之类的值，则会显示该区域。当我尝试使用match_parent或任何其他组合时，仍然存在相同的问题。我还尝试将高度和宽度设置为设备高度和宽度，但仍然没有运气。
在我的CreateWeddingMetadataFragment中的onCreateView方法中：
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) {
}
});
在我的CreateWeddingMetadataFragmentDialog中，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;
}
这是我尝试将其设置为设备大小的结果。
