android - PopupWindow 中的 Horizo​​ntalScrollView

Question

我尝试使用 preView 创建 popupWindow，用户可以在其中查看图库中的图像。但是第一张和第二张图片是隐藏的，并且在 scrollView 的末尾是空白区域，就像屏幕截图中一样。

我正在尝试使用
layout.addView(imageView);

private void showAttachmentPopup() {
    LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.attachemnts_file_popup, null, false);
    PopupWindow pw = new PopupWindow(popupView, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
    params.addRule(RelativeLayout.BELOW, findViewById(R.id.layout_sent).getId());
    popupView.setLayoutParams(params);
    LinearLayout layout_attachment = (LinearLayout) popupView.findViewById(R.id.layout_attachment);
        RoundedImageView roundedImageView = new RoundedImageView(this);
        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
        lp.setMargins(5, 5, 5, 5);
        roundedImageView.setLayoutParams(lp);
        roundedImageView.setScaleType(RoundedImageView.ScaleType.FIT_XY);
        roundedImageView.setImageBitmap(bitmap);
        layout_attachment.addView(roundedImageView);

    pw.setOutsideTouchable(true);
    pw.setBackgroundDrawable(new BitmapDrawable());
    pw.showAtLocation(mBtnAttach, Gravity.BOTTOM | Gravity.LEFT, locateView(mBtnAttach).bottom, locateView(mBtnAttach).right);
}

如果我几次尝试添加此位图，就会发生此错误。在我的 xml 中，只是将 Horizo​​ntalScrollView 和 LinearLayout 放到这里

我(猜)我有同样的问题，看起来一样。

对我有帮助的是设置 adjustViewBounds:

roundedImageView.setAdjustViewBounds(true);

希望它适合您的情况!
