bottomSheetDialogFragment全屏

问题描述

我想要实现的是类似于Instagram应用内网络浏览器的功能，该功能可在您点击广告时使用:

What I'm trying to achieve is something like Instagram in-app web browser, used when you click an ad:

我做了什么，是我使用了WebView bottomSheetDialogFragment，还是重写了 onCreateDialog 来获得全屏显示，如下所示:

what I did, is I used a WebView bottomSheetDialogFragment, and I override onCreateDialog to get the full screen like this :

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    BottomSheetDialog bottomSheetDialog=(BottomSheetDialog)super.onCreateDialog(savedInstanceState);
    bottomSheetDialog.setOnShowListener(dialog -> {
        BottomSheetDialog dialogc = (BottomSheetDialog) dialog;
        FrameLayout bottomSheet =  dialogc .findViewById(android.support.design.R.id.design_bottom_sheet);
        BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
        //BottomSheetBehavior.from(bottomSheet).setSkipCollapsed(true);
        //BottomSheetBehavior.from(bottomSheet).setHideable(true);
    });
    return bottomSheetDialog;
}

这是我得到的结果:

我的问题是，如何获得全屏效果，或者如何实现instagram浏览器之类的功能?

my question is, how can I get the full screen effect, or how can achieve something like instagram browser?

ps:我尝试了第一个chrome自定义标签，但无法将其添加到对话框片段中.

ps: I tried first chrome custom tabs, but I couldn't add it inside dialog fragment.

谢谢.

推荐答案

在您的自定义 BottomSheetDialogFragment ，您可以使用类似的东西:

In your custom BottomSheetDialogFragment you can use something like:

  @NonNull @Override public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.setOnShowListener(new DialogInterface.OnShowListener() {
      @Override public void onShow(DialogInterface dialogInterface) {
        BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) dialogInterface;
        setupFullHeight(bottomSheetDialog);
      }
    });
    return  dialog;
  }


  private void setupFullHeight(BottomSheetDialog bottomSheetDialog) {
    FrameLayout bottomSheet = (FrameLayout) bottomSheetDialog.findViewById(R.id.design_bottom_sheet);
    BottomSheetBehavior behavior = BottomSheetBehavior.from(bottomSheet);
    ViewGroup.LayoutParams layoutParams = bottomSheet.getLayoutParams();

    int windowHeight = getWindowHeight();
    if (layoutParams != null) {
      layoutParams.height = windowHeight;
    }
    bottomSheet.setLayoutParams(layoutParams);
    behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
  }

  private int getWindowHeight() {
    // Calculate window height for fullscreen use
    DisplayMetrics displayMetrics = new DisplayMetrics();
    ((Activity) getContext()).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    return displayMetrics.heightPixels;
  }
