android - 为什么我的 TextInputLayout 的 outLine 框没有出现？

Question

我想用大纲框包裹我的编辑文本，所以我使用 TextInputLayout ，但是当我使对话框全屏显示时，大纲框不会出现。

我发现问题是因为我正在使用这行代码使(作业对话框)全屏显示:

   setStyle(STYLE_NO_TITLE,R.style.DialogHomework);

这是我的作业对话框 xml:

我的作业对话框代码:

  public class newHomeWork extends DialogFragment {

public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(STYLE_NO_TITLE,R.style.DialogHomework);
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View dialog = inflater.inflate(R.layout.homework_dialog,container,false);
    Toolbar toolbar = dialog.findViewById(R.id.toolBar);
    toolbar.setTitleTextColor(getResources().getColor(R.color.colorPrimaryDark));
    TextView textView =toolbar.findViewById(R.id.homeworkDialogTitle);
    textView.setText("Add homework");
    Button add = dialog.findViewById(R.id.addHomework);
    Button cancel = dialog.findViewById(R.id.cancelHomework);
    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


        }
    });
    cancel.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dismiss();
        }
    });


    return dialog;
}

@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {

    Dialog dialog =  super.onCreateDialog(savedInstanceState);


    return dialog;
}

@Override
public void onStart() {
    super.onStart();

}
}

我的 DialogHomeWork 风格:

 <style name="DialogHomework" parent="Theme.AppCompat.Dialog">
    <item name="windowNoTitle">true</item>
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowFullscreen">false</item>
    <item name="android:windowBackground">@color/colorPrimary</item>
    <item name="android:background">@color/colorPrimary</item>


</style>

您可以设置 TextInputLayout 的样式:

Widget.MaterialComponents.TextInputLayout.OutlinedBox

这应该可以完成任务。

简单的例子:

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Test me">

    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</com.google.android.material.textfield.TextInputLayout>
