我尝试使用 preView 创建弹出窗口,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被隐藏了,并且在 scrollView 的末尾是空白区域,就像在屏幕截图中一样。
我尝试使用
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);
}
如果我尝试添加此位图几次,则会发生此错误。在我的 xml 中只是将 HorizontalScrollView 和 LinearLayout 放到这里
