I have a LinearLayout that contains three TextViews. I want to highlight a TextView or the whole Layout when user clicks on the TextView. Is they any way to make it happen?

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'm trying to accomplish something fairly simple but struggling to get the right combination of layoutWidth/weight to make this work.
I have a horizontally oriented LinearLayout with width fill_parent containing two TextViews. The TextView on the right has variable width text, and I want the TextView on the left to adjust its size accordingly to as much width as possible. Essentially, the right TextView must always show all of its contents and the left TextView should extend as far as possible to the edge of the TextView on the right.
I try to add a texview to linearlayout dinamiclly such as in the following code, but it doesn't appear when i run the application ?
setContentView(R.layout.advanced);
m_vwJokeLayout=(LinearLayout) this.findViewById(R.id.m_vwJokeLayout);
m_vwJokeEditText=(EditText) this.findViewById(R.id.m_vwJokeEditText);
m_vwJokeButton=(Button) this.findViewById(R.id.m_vwJokeButton);
TextView tv=new TextView(this);
tv.setText("test");
this.m_vwJokeLayout.addView(tv);
I mean widgets that are not going to be touched through program code.

It seems that a TextView inside a LinearLayout forces that LinearLayout to be larger. I am trying split my screen top 50% and bottom 50% and also the bottom 50% is split into 3 parts. So I did my weights 3 (for the top), and then 1, 1, 1 (for the bottom) for a total of 6.
Here is what it looks like. http://i.imgur.com/3FJSW.jpg
As soon as I take out the TextView inside the first LinearLayout the splits are proper. The moment I put the TextView inside the top LinearLayout the top LinerLayout gets larger by the amount of the the TextView.
Here is my code:
CODE:............................
We are using TextView's Ellipsize function to scrolling text in it and there many other controls in our window. We noticed CPU would go up to 50% if text started scrolling. After digging deeper, we found all controls in our layout kept drawing when texts scrolling. We wonder why? And how to avoid all controls redrawing?
View 8 Replies View RelatedI'm currently rendering HTML input in a TextView like so:
CODE:......................................
The HTML being displayed is provided to me via an external resource, so I cannot change things around as I will, but I can, of course, do some regex tampering with the HTML, to change the href value, say, to something else.
What I want is to be able to handle a link click directly from within the app, rather than having the link open a browser window. Is this achievable at all? I'm guessing it would be possible to set the protocol of the href-value to something like "myApp://", and then register something that would let my app handle that protocol. If this is indeed the best way, I'd like to know how that is done, but I'm hoping there's an easier way to just say, "when a link is clicked in this textview, I want to raise an event that receives the href value of the link as an input parameter"

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.

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

View 15 Replies View RelatedI am seeing an annoying bug in WebView on the G1.I have a WebView that displays an HTML page. When the user clicks on a link, the link's text is highlighted.At this point, I call WebView.clearView(), and then WebView.loadDataWithBaseURL() to load the URL that the user has just clicked on.When the new page finally shows, the WebView somehow still remembers the previous highlight area. If the user clicks on the WebView again, a "phantom highlight" at the old location will flash quickly.The phantom highlight also appears when the user moves the trackball.

View 2 Replies View RelatedI have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.
