android - BottomSheetDialogFragment在横向模式下不显示完整高度

我在 Activity 中使用BottomSheetDialogFragment，该对话框在纵向模式下显示全高，但在切换到横向模式时未显示全高。

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomBottomSheetDialog customBottomSheetDialog = new CustomBottomSheetDialog();
        customBottomSheetDialog.show(getSupportFragmentManager(),customBottomSheetDialog.getTag());
    }
}

public class CustomBottomSheetDialog extends BottomSheetDialogFragment {

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return View.inflate(getContext(), R.layout.view_config, null);
    }
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:background="#fdf107"
              android:layout_height="wrap_content">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="196dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:text="BottomSheetDialogFragment"/>

</LinearLayout>

在横向模式下，我必须拖动BottomSheetDialogFragment以查看整个内容。

最佳答案

解决此问题的方法是。

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            if (Build.VERSION.SDK_INT < 16) {
                view.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            } else {
                view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            }
            BottomSheetDialog dialog = (BottomSheetDialog) getDialog();
            FrameLayout bottomSheet = (FrameLayout)
            dialog.findViewById(android.support.design.R.id.design_bottom_sheet);
            BottomSheetBehavior behavior = BottomSheetBehavior.from(bottomSheet);
            behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
            behavior.setPeekHeight(0); // Remove this line to hide a dark background if you manually hide the dialog.
        }
    });
}
