问题 I make an timetable application for android and I'm using ViewPagerIndicator as fragment. But now I've a problem, I want to get the TabPageIndicator to the center. Like this: And I would to like to set the individual tab width and height. And set that tab to a drawable that support selected/pressed states. I've not found it yet to solve these problems.

问题 i have a HorizontalScrollView, and i am adding a bunch of ListView as its children. my XML file looks something like the following. for brevity, i will omit some of the attributes. <HorizontalScrollView> <LinearLayout> <ListView android:id="@+id/listView1" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </LinearLayout> </HorizontalScrollView> in my java code, i then populate the ListView with data. If there is only 1 or 2 records, the ListView does not extend all the

问题 I am trying to implement HorizontalScrollView using this sample code. I have to fetch data from server, so I have made changes as per my requirement, however I am neither getting data nor any error, just blank activity. I don't know what missing. I am able to get data from server, see logcat result below and here is my complete code: MainActivity.java public class MainActivity extends Activity { CenterLockHorizontalScrollview centerLockHorizontalScrollview; ArrayList<Actors> actorsList;

问题 I'm making an app with fairly complex UI. Its comparable to a horizontal list view that expands to a viewpager on being clicked. Presently, I've implemented this using the most basic approach. I simply inflate views inside a horizontalScrollView and inflate another subview with animation whenever user taps on any parent view. This works perfectly fine and gives it a look of horizontal expandable listview. However, I feel this approach is highly inefficient since I keep on getting GC warnings

问题 I have a parent horizontalScrollview that contains various layouts. In one particular layout there is a scrollview. Inside that scrollview there is edittext. Now when I click on any edittext for input, the horizontal scrollview automatically scrolls the screen to some other layout and I am not able to see the current active layout(containing scrollview). I know nested scrollviews is a bad coding practice but I can not change it in this case as there will be large amount of rework. Is there

问题 I am making an app that is using HorizontalScrollView for showing list of items. So I have multiple views inside HorizontalScrollView for horizontal scrolling. I am changing the layout size of a view on detecting pinch zoom according to scaleFactor I have implemented it at view level so when user pinch zoom having both finger inside a single view, that view is detecting pinch zoom and changing its size but when I pinch zoom with my fingers in different views this is not working. I want to

问题 I just would like to ask if these Layouts can hold fragment/multiple fragments. I base this on google play store. Sorry for bad logic. 回答1: Yes , scroll views can hold multiple fragments. However , managing the fragment stack gets tricky. Because fragmentManager/ChildFragmentManager will only maintain stack for one container, if I am not wrong. As long as you don't add them dynamically in run time,it is easy. i.e. if the fragments are described in the scroll view from xml layout and you don't

问题 I have an HorizontalScrollView and I am adding buttons in LinearLayout inside HorizontalScrollView and had set onClickListener to buttons. When I scroll the ScrollView and immediately click on any button it never responds to onClick , but 3-5 seconds after scrolling, it responds to onClick. Please explain how can I get ride of this. Am I missing something? <HorizontalScrollView android:layout_height="wrap_content" android:layout_width="600dip" android:layout_centerInParent="true" android

问题 This seems to be a very silly problem but its just not working for me. I have 2 ImageButtons & a HorizontalScrollView(HSV) on a page. Strangely one of the Image Button(1st one) is not clicking. Also I wanted to make the HSV clickable so I used: android:clickable="true" , which does not work You can use the xml & activity exactly as I have posted. This is the xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout
