Android :: ScrollView With Buttons Inside / No Response Until Second Click On Any Button Inside
Oct 30, 2010
I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.

So I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?

I have a LinearLayout inside a ScrollView that has android:layout_height="fill_parent", but it doesn't expand to the full height of the ScrollView. My layout looks something like:
CODE:........
I can see that the LinearLayout doesn't expand the full height of the ScrollView because in Eclipse in Android Layout Editor, if I select the ScrollView (in the Outline panel) it is highlighted with a red border that fills the screen to the bottom but when I select the LinearLayout its highlight doesn't expand to the bottom of the screen. How can I get it to do so?
The effect I'm trying to achieve is to have some text and a button below it (inside the LinearLayout in level 4 there's just a button). The text can be big enough to need a scrollbar, in which case I want the user to have to scroll down in order to see the button. In case the text is not big enough for a scroll bar, I want the LinearLayout containing the button to stick to the bottom of the screen.
At first I thought I shouldn't post the full XML because it's usually a turn-down to see a huge chunk of code in a question. However, it seems it might be necessary, so here's the full layout.
CODE:........
At the moment I have resorted to android:layout_gravity="bottom" on the problematic LinearLayout, which makes the button stick to the bottom of the screen no matter what. But that also makes the text stick to the bottom of the screen, which is not exactly what I was after.
Update: scratch that, android:layout_gravity="bottom" makes the ScrollView unable to, well, scroll.

I've extended ViewGroup to achieve something like a FlowLayout.I put my custom ViewGroup into a ScrollView, dynamically add a bunch of content and it doesn't scroll.The content that flows off the screen is not viewable.What am I missing, how can I allow my ViewGroup to be compatible with ScrollView?

I'm able to successfully use a ScrollView inside the layout xml file for an application. However, when I tried using a ScrollView inside the layout xml file for a widget, I get a "Problem Loading Widget" error as soon as I drop the widget in the emulator. If I comment out the ScrollView, then the widget shows up in the emulator. I've pasted my layout xml file below. Any thoughts on how to get past this error would be much appreciated.

I have a click listener:
private OnClickListener onMyListener = new OnClickListener() {
public void onClick(View v) {
myMethod();
} };
And my Method:
private String myMethod() {
TextView tv = (TextView) findViewById(R.id.TextView1);
return (String) tv.getText();
}
When it calls this method, at tv.getText() it breaks in the debugger.
With this in the stack --
ViewRoot.handleMessage(Message) line: 1571
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123

I'm trying to build an activity that has a checkbox on top, a button at the bottom, and a bunch of other widgets scrolling in between. Conceptually that'sWhen it renders I get the checkbox at the top, the stuff scrolling nicely underneath, but the Button drawn offscreen (I assume) below the ScrollView. The only way I can get the Button to be visible is to hard-code the height of the ScrollView, which of course only works on one screen-size. I've tried all combinations of gravity and layout_weight I can think of to no avail. Am I using the right combination of Views? Anybody managed to get this working?

I got a ListView item that contains a button inside. Currently the long press of a ListView item does not get processed. I thought that by setting the Button.setLongClickable(false) would allow the long press to be passed along to the ListView item and it's not happening.

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

I currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows. That all works just great, but I want to add them to a RadioGroup so only one button can be toggled at a time. When I tried to add the dynamic RadioButton to the RadioGroup AFTER I added it to the table row, I got an error saying that the child (the RadioButton) already had a parent. I agree, it does have one, the TableRow.
can you have radio buttons tied to a radio group inside of a row or, should I just code my own toggle mechanism and avoid RadioGroup all together? I mean, I could code the onClick to unclick all other radio buttons, but I would rather not do this if I can use the build in RadioGroup.
<ScrollView
android:id="@+id/ScrollViewModifyGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent".............

I have multiple radio buttons which I want to layout using a table but also include them in a single radio group. I have the following xml layout:
<RadioGroup android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/Group1">
<TableLayout android:id="@+id/RadioButtons"
android:layout_width="wrap_content".........
But unfortunately the radio buttons inside the table seem to ignore the fact that they're inside of the RadioGroup tags and because of this you can select more than one radio button at the time. I noticed that by removing the table and just having the radio buttons it works just fine. How can I overcome this? Would it be as simple as declaring the radio group inside of the table instead of outside?

My activity runs in simulator, and I use mouse to control it. When I select the item in listview by turning scroll wheel, the background of item becomes orange. But, when I "click" the item in listview, the item does not response to my action. You received this message because you are subscribed to the Google Groups "Android Developers" group.

I'm wondering whether it would be possible to run ADB (Android Debug Bridge) inside an existing Android device. I saw this, but what I want is to be able to compile an ADB binary (plus any necessary libraries) for Android, put it on my sdcard, and run ADB commands from within a terminal emulator.
Secondly, I'm wondering whether, after installing ADB on one device (device #1), I could connect that device and another device (device #2) together, and use device #1 to perform ADB commands on device #2 (for example, rooting device #2 without needing a PC).
