ListView in Fragment in ViewPager in ScrollView for android >=2.3

最后都变了- 提交于 2019-12-03 08:52:08
Is it possible to do it? The main point are: A Complex header out of the listView but that must scroll A ListView whose scroll is handled by the far ScrollView parent. The ListView must have recyling, so the linearLayout cannot be a solution Thanks to directly answer the question: Is it possible to do it? Yes it is. You can see this example here in the Albums and Profiles sections. But it's not simple, nor straight forward. There're two issues in adding a ListView inside a ScrollView (you can research that on your own) that is TouchEvents get mixed up because it doesn't know which View will

ListView row marker ala GMail

落花浮王杯 提交于 2019-12-03 08:44:47
I am interested in creating a ListView where each row is marked the way it is done in GMail for 3.0+. This creates a nice separation of the left and right ListFragment. Other examples include also Google Calendar on 2.3.4 for instance where a color marker is on the left of the ListView. See the grey vertical divider between the two lists. How does one achive something like this? A bonus would be also the alternating width, but I guess that is only a smaller layout change. I know I could probably do something like inserting an ImageView in there and then fill it with the color I would like but

ListView scrolling using UniversalImageDownloader not smooth

江枫思渺然 提交于 2019-12-03 08:34:31
I am using a ListView containing images. These images are loaded from the Internet inside the adapter. Therefore I am using the UniversalImageDownloader . Unfortunately the scrolling of the ListView "lags" for a short time as soon as I scroll down where new content has to be downloaded. I acutally expected behaviour like the ListView scrolls perfectly smooth, but the loading of the Image can of course take some more time - which should not effect the smoothness of scrolling. Furthermore, as I scroll back up the lags occur as well. It seems as if the images are not cached properly. Maybe my

EditText in ListView is updated by onTextChanged when scrolling

懵懂的女人 提交于 2019-12-03 08:16:17
I have been searching for an answer to this, but the solutions don't seem to work for me. I have a TextView and an EditText in a list item. I am trying to update the stored values for the EditTexts when the user edits them. @Override public View getView(int index, View convertView, ViewGroup parent) { ViewHolder holder = null; final int pos = index; if (convertView == null) { convertView = mInflater.inflate(R.layout.user_details_list_row, parent,false); holder = new ViewHolder(); holder.mCaptionTextView = (TextView)convertView.findViewById(id.user_detail_row_caption); holder.mDetailEditText =

Is using AsyncTask still recommended for loading listView items in the background?

狂风中的少年 提交于 2019-12-03 07:33:14
Background I've heard that there are some new solutions for loading data in the background which are more recommended than AsyncTask (like loaders ). The problem AsyncTasks are great and easy to use. However, it has some limitations: The class itself has to be modified since it's limited by the number of pending tasks (about 256 or so). Of course, in a listView's adapter, I always cancel a task if it's not needed(for example when I need to update a view that was used for a different item). I also have to cancel them all (or handle in a different way) when the activity/fragment is being re

ViewPager in a ListView - how to lock the scrolling axis?

ぐ巨炮叔叔 提交于 2019-12-03 07:27:59
问题 I have a ViewPager widget in every row of a ListView. This provides a shelf-like UI, so the user can scroll around searching for a shelf vertically, and then scroll horizontally amongst the contents of a shelf. This works. But the scrolling experience is terrible: if I start to drag a shelf's ViewPager, scroll it horizontally, and accidentally drag a bit upwards/downwards, then the ListView "traps" this dragging action, and start to scroll vertically, ending my horizontal drag. In this state,

Android's RelativeLayout seems broken

僤鯓⒐⒋嵵緔 提交于 2019-12-03 06:32:37
I'm working on a layout where I use a ListView with RelativeLayout line items. The lineitems themselves are not displaying correctly. The issue is that the txtVideoDuration TextView is drawn at the top of the line item instead of the bottom. Because of this the txtVideoTitle gets a height of 0. As you can see in the XML the txtVideoDuration is supposed to be clamped to the bottom of the ListView. My goal is to have the layout resemble the tutorial that google gave me. Example: http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html I'm using Android 2.0.1. I've even plugged

Android displaying text when ListView is empty

陌路散爱 提交于 2019-12-03 06:23:01
问题 I'm setting a TextView with the id @android:id/empty to display a message when there are no items in the ListView . However, this TextView gets displayed even if there are items in the ListView , right before the items show up. How can I make it such that it only gets displayed when there are no elements in the ListView ? <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height=
