Android :: Long Click On Child Views Of A ExpandableListView / Enable It?

Feb 28, 2010

ExpandableListView has a setOnChildClickListener method, but lacks of setOnChild*Long*ClickListener method.

When I added setOnLongClickListener() on child view in getChildView(), whole sublist became completely unclickable (despite of parentView.setOnChildClickListener() present and working before).

How can I enable long clicks on child views?

Android :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background

Jan 6, 2010

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.

The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.

The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.

What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

Android :: Hide Child Dividers In ExpandableListView

Jul 14, 2010

I need to completely remove dividers from ExpandableListView. As for parent items it's a setDividerHeight method where I can pass a zero value. But there's no similar method for child divider. Is there any way to hide it?

Android :: Do Root Views Of An Activity In Android Have Any Prior Knowledge Of The Child Views That Will Be Loaded Into Them

Jan 25, 2010

Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Android :: In An ExpandableListView - Show One Additional Line At The End Of The Child Results?

Jun 1, 2009

I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work.

If a group has three children what I have working looks like this:

Group
NormalChild
NormalChild
NormalChild

But I'd really like something like this:

Group
NormalChild
NormalChild
NormalChild
AlternateChild

The idea being that the AlternateChild could be a link to more info about the group.

ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible

Android :: Make ScrollView With A RelativeLayout With Multiple Child Layouts Fill The Screen

Aug 20, 2010

I have a layout that has just a ScrollView visible. It has a relative layout as its child. This layout has several other layouts (mainly text views) as its children. When the text is not big enough, the scroll view does not expand itself to fit the whole screen. Instead, it shows a gap at the bottom where the background shows. I tried setting fillViewPort=true on the ScrollView, but that just made the first child layout (RL1) to fill the screen.

Android :: Adjust Height Of Group Headers In An ExpandableListView Dynamically?

Oct 7, 2010

I have an ExpandableListView (ELV) with the groups having LinearLayout. I have set the height of the group to some value (38dip in this case, equivalent to two lines of text). If the group heading is long and would take more than 2 lines, it is not shown properly in the ELV item - some part of the view gets scrolled. On the other hand, if I change android:layout_height to "wrap_content" in the LinearLayout, the groups always show all the lines. But the line widths are variable, i.e., short titles show up with only 1 line and long titles show up with 2, 3 or 4 lines. That looks ugly. I would like to implement the height to be something like max("38dip", "wrap_content"). Is there a way to do this?

Even programmatically, I do not seem to be getting the actual height of the group if I set android:layout_height to "wrap_content". Any suggestions there?

Android :: Re Ordering Child Views Of A Layout

Aug 29, 2010

I have a number of child views, each child is a TableRow and I need to be able to change the order of the TableRows, such that I can swap the rows into any order. I know there is a method called removeAllViews() but I don't really want to remove and re-create the views if its possible to access and change the order. I really want the display to update as smoothly as possible, taking the minimum amount of time, is it possible?

Android :: Why Add Child Activities To TabActivity Instead Of Simply Using Views

Mar 17, 2010

I've been programming in Android for two years now and just joined an Android project where they are using a TabActivity to host multiple Activities. It's unclear why this is better than rewriting the TabActivity to simply use Views instead.

TabActivity extends ActivityGroup which means TabActivity can host both Activities and Views. But what's the use of this capability? I was under the impression that Activities should be treated as individual screens of an application.

In short, what is an example use case where it's recommended that TabActivity should host multiple Activities rather than multiple Views?

Android :: Multiple Child Views Created Programmatically Not Working / Make It To Do?

Sep 27, 2009

I need a LinearLayout to contain 3 TableLayouts, and I can't get it to work. This is where the problem is I'm sure:

mTableLayout.addView(mLinearLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(nTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(oTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(pTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

How Do I make this work? I can get it to work just find when I only add a single child view, but when I have multiple children view objects my app crashes.

Android : Aren't Focus States Supposed To Bubble To Child Views?

Apr 19, 2010

When using a View within a View, for example an ImageView within a LinearLayout, both of which have xml drawable resources (the LinearLayout as a background) specifying PNG drawables to use for the on/off states, shouldn't children Views receive the focus state when their parent gets focus? So as far as I understand, both my LinearLayout and ImageView should be switching to their focus states right? Apparently not Or, more likely, apparently my implementation is incorrect.

The focus state works on the LinearLayout but my ImageView never receives focus.. I have both Views set to android:focusable="true".

Android :: Change Nested Layout's Child View Group's Width In Java Code?

Oct 6, 2010

I have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this

ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);

I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.

Android :: Child TextView In ScrollView With Large Amount Of Text Pushes Other Views Off The Screen

May 6, 2009

I am trying to create an activity layout that has a top level vertical linear layout like so:

CODE:................

This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?

I've tried playing with weights (e.g., giving the top text view a weight of .2, the scroll view a weight of .7 and the button a weight of .1, but to no avail.

Android : Group Of Views Controls On Multiple Screens

I want to know the best way to do this without creating new buttons for every activity. I have been around programming (C++/C#) for many years but am pretty new to Android and Java so if someone can point me in a general direction.

Android :: Child Views Of Particular Table Row In Table Layout?

Jul 15, 2009

Here is my screen description: It is a TableLayout and it contains multiple Rows. I have set TableRow as clickable, as I want to go to next screen on click of a tableRow. Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.

Android :: Multiple Activites That Share 75% Of Layout - Layouts Within Layouts?

Sep 6, 2010

I'm creating a game where there's a screen that, for the most part, is shared by four different activites - but a key portion of the screen will be completely different, depending upon which activity is active. Basically, on the left will be an image of the player and along the bottom there will be a row of buttons (let's say for Armour, Weapons, Magic, Skills). This leaves the top-right portion, which will need to dynamically change to represent the button pressed. (So, one moment the top-right portion is the armour selection activity, and the next it's the weapon selection activity, and so on.)

Is this possible? Can I have a layout within a layout and dynamically point the nested layout at a (nested) layout.xml of my choosing? Or, am I looking at just duplicating most of the layout four times (for the four different activities?) Or, am I going to be looking at linking the four activities to a (the top-right) view component, and then having to dynamically construct all of *that* view's child views based on the currently active activity? Well, that's about as much sense as I can make this question make.

Android :: How Can Update The All The Views Inside A TabHost When Pressing On A ContextMenu Item From Within One Of The Views

Nov 16, 2010

I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.

i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.

Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.

How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

Android :: Switching Views With RadioButton And Saving Views In Bundle

Mar 6, 2010

I have the following XML code:.................

The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.

Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
