Android :: LinearLayout Fill Middle
Aug 1, 2009
I have a vertical, set height (300px) LinearLayout (LL) with 3 nested LLs. 1 and 3rd are set with android:layout_height="wrap_content" and the middle one with android:layout_height="fill_parent". To my dismay, 3rd LL get's pushed out with 2nd one filling parent layout right to the bottom. How do I achieve desired effect since I want potentially resize the outside container with the middle portion expending and contracting to accommodate the change

Let's say I want to make a layout that has 3 TextViews, one on top of the other. But, I want the top TextView to always "stick" to the top of the screen (regardless of orientation), and I want the bottom TextView to always "stick" to the bottom of the screen. Then I want the middle TextView to always fill the available space in between (again, regardless of screen orientation). I've had no luck with LinearLayout and I've come close with RelativeLayout but neither have provided by desired solution.

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

If I create a new arraylist of size 5...
And then I try to add to the middle of that arraylist...orderedPlayers.add(2, P);
I get an indexoutofbounds...I also get indexoutofbounds if I use set instead of add...orderedPlayers.set(2, P);
In fact the only way I can add P to the arraylist is if I use the 0 index...orderedPlayers.add(0, P);
And also for some strange reason when I do that my debugger in eclipse sees that element added to the 4th index of orderedPlayers instead of the 0th... is ArrayList buggy or am I completely missing something? how would I add to the middle of a null ArrayList?

Hopefully this is a simple one as I've been asking loads recently...
I am trying to draw the a white circle with the following code...
but it is being displayed as a solid disk, how do I get it to just display as an circular outline with a transparent centre?
I've had a look in the help and it makes no sense to me, probably because I'm not used to the drawing terms like stroke and dither. What's wrong with background and border eh?

Is it possible to make TextView to break words in the middle and then move to another line, instead moving whole word that doesn't fit to the new line ? I have a width and number of lines of the TextView and a long string and want to calculate which portion of the String will fit exactly. the code is TextView vTextShort = (TextView) findViewById (R.id.story_text_partial); int lineHeight = vTextShort.getLineHeight(); int nmbLines = mesuredHeight / lineHeight; Paint mPaint = vTextShort.getPaint(); String shortTextStr = mStoryText; mStoryBreakIdx = 0; vTextShort.setLines(nmbLines ); int breakText = mPaint.breakText(mStoryText.toCharArray(), 0, mStoryText.length(), mesuredWidth, null); mStoryBreakIdx = breakText * nmbLines; It seems to calculate number of chars accurately but not accounting for the space that left after word is moved to a new line if it doesn't fit fully. And i'm looking on how to either break words in the middle or how calculate a width of the text that will fit correctly.

I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.
Here is my code.

How would you fill in a form on a webpage (not under my control) in an Android program?I want to write a little android program to automate interacting with a website that someone else has written and I can't change. It has no published API.It is step 4 I'd like the help with. If I wasn't using Android I'd use a library library like libcurl (for python) or apache httpclient (for normal java), or I'd do some DOM interaction with a webbrowser. What would you recommend doing for android? Is there something built into the standard libraries you'd recommend?I'm a pretty experienced Java programmer but all I've written in Android is hello world, if that affects your answer.

I want to send an SMS from an application, but without needing the SMS permission, using an intent. This way the user can also decide if he/ she really wants to proceed to send the SMS.mms-sms"); startActivity(sendIntent); However, when the SMS screen now shows, the number is not filled in. The SMS body is however filled in. This happens on the emulator and on a phone. What am I doing wrong please?

I'm trying to use a Helvetica outlined ttf and i want the background of the font to be yellow and the outline part be black.but it does not work, the font is drawn with the black outline but no yellow background. In fact I am not even sure what does the bgColor field from TextPaint is for, i haven't found information about it in the doc. I've also tried to use the setBackgroundColor(Color) method from TextView but it doesn't fill the font inner part but all the TextView space.

Pulling my hair out on this one. I want a dialog that contains a ScrollView with an embedded TextView that will contain what could be a couple of pages of text. Below the ScrollView I want a close button. Everything I try that doesn't involve directly setting the height of the ScrollView results in the ScrollView filling the dialog and the button being invisible because it has been pushed off the bottom. I've tried about every combination I can think of for layout_height and layout_weight of both the ScrollView and the Button but always get the same result.

My dialog shows a relativelayout, which is set to fill_parent in both width and height. However, it doesn't fill the whole screen. I tried settting the window flags to full screen but that didn't help either. Can someone tell me how to do this?

I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added.
For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons.
It can't scroll either, it just has to dynamically fill the layout with buttons.

I have a simple ExpandalbeList. For the group header view, I'm using a simple TextView, I am setting the background of the text to a drawable. I have the textview parameters set to FILL_PARENT, but the background of the TextView only covers the width of the text. I realize that I can put this all inside of a Linear Layout, but that just seems like a waste. isn't there a way to make the bounds of the text view stretch to the edge of the listview?

I feel so much better about my keyboard. I have been using the stock one, but it gives me fits with my man hands and correcting my texts has been a pain in the ass.I finally sat down and researched a lot of keyboards and tried out a bunch on my Stock 2.2 Evo.Anyway, the keyboards on the marketplace are crap. They promise tons of options, but work as well as the stock keyboard. Then I heard about the Droid X keyboard, and spent about 2 hours installing and playing with different versions before discovering that they didn't run on 2.2I finally found one here that worked perfectly. It is amazing.
