This is my layout...
This xml is the main.xml with main.java. How can i embed intro.xml with intro.java into the <Textview>?
I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

View 2 Replies View RelatedSo my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?

I want to display an ordered list inside a TextView.

I have a Spinner with an ArrayAdapter that feeds Values into it. The layout for this views looks something like this:
CODE:.................
The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot:
I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid:
CODE:........................
Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup?
It would help me a lot if I could see an example of the adapter initialization and the textview definition?
I was wondering if its possible to set multiple styles for different pieces of text inside a TextView. For instance, I am setting the text as follows:
CODE:...........................
Now, is it possible to have a different style for each text element? I mean bold for line1, normal for word1 and so on...
I found this http://developer.android.com/guide/appendix/faq/commontasks.html#selectingtext:
Get our EditText object. EditText vw = (EditText)findViewById(R.id.text);
Set the EditText's text. vw.setText("Italic, highlighted, bold.");
If this were just a TextView, we could do: vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE); to force it to use Spannable storage so styles can be attached. Or we could specify that in the XML.
Get the EditText's internal text storage. Spannable str = vw.getText();
Create our span sections, and assign a format to each.
CODE:............................
But it uses position numbers inside the text. Is there a cleaner way to do this?
Is there any way I can load a class based on what version of the OS the phone is running? For example:
I made an app which requires 1.6+ Android. Is there a way for me to load one class or the other based on what OS the phone is running? I'm asking this specifically for contacts. The database was changed from 1.6 to 2.0 and the old version doesn't retrieve contacts on the new OS phone. I'd still like to keep my 1.6 requirement, but at the same time I'd like 2.0+ phones to access the contact part of the app.
So can I make 2 APIs, somehow pack them with the app and decide on the fly which I choose to import?
I am desperately trying to set TextView attributes of cells within a table programmatically but can't get this to work! Whenever I set layout properties, the field will simply not appear (but not give any error or exception). I boilded this down to this simple example:
CODE:.......
This will show three fields, but when you uncomment the five commented line, then NOTHING will appear. Why is that so? Why does setting layout parameters cause my TextView's to not appear? I'm stuck! What am I missing?
Here's the manifest, if some kind soul quickly wants to try this out:

I can use android:gravity="bottom|center_horizontal" in xml on a textview to get my desired results but I need to do this programmatically.

I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?

View 1 Replies View RelatedI've got a ListView where each item in the list is contains several controls. One of the items is a checkbox, and I can check/uncheck it without problems. The other items are some TextViews and a WebView. I've got autoLink turned on and linksClickable turned on, but I can't get links to fire up the browser when I click on them. This applies to both TextView and WebView. I've tried changing the parent to a GridView instead of a ListView, playing with setFocusable(), and all that, but to no avail.
Is it even possible to have interaction on the TextView-based elements of a row in a ListView? It seems like that *should* be possible, but I've been banging my head against this problem for a few weeks with no progress. What's the secret?
Right now I have a class that extends LinearLayout and builds the view inside of the constructor using a series of addViews. I wanted to move this into an XML file, so I have the same view defined there. My problem is that I can't figure out how to load the XML file in the constructor of the derived class. I looked up the LayoutInflater stuff, but I wasn't entirely sure how to use it in that context. Do I need to call addView() with the result of the LayoutInflater? Is this even possible? The other issue is that the context object that is passed in doesn't have the LayoutInflater methods. I'm not sure if I need an instance of Activity to do that.

View 4 Replies View RelatedI have code which has one activity which passes information to a second activity.
I can use this information to pass to a third activity with additional information from the result of the second activity.
I want to use gestures as a method of going back to a previous activity, but if I go back from the third to the second activity I need the information initially passed from the first to the second activity to still be present.
i.e.
First Acticity
what is Y?
answer y = 5
Second activity
User said Y = 5
what is X?
Third Activity
User said Y = 5
X = 6
Go back to Second activity but maintain the input of
User said Y = 5.
To do this I have used a bundle to pass the information between activities, but I can only access the info in the bundle from within a method within the class started by the intent.
The gesture controls are within another class, so I cannot access the bundle information from within this class as the getIntent command produces a not defined error.
What I need to do is to be able to pass the information from the bundle from the first activity to the gesture class so that I can pass it back when I go back using the gestures.
I was trying to make an anonymous class to upload a file to a server.
I wanted to make that easily reusable much like some kind of component.
Everything works fine but as a final touch i wanted to add a function to check if internet connection is available.
Problem is, the call to the connectivity manager needs the Context :
ConnectivityManager connec = (ConnectivityManager) getSystemService (Context.CONNECTIVITY_SERVICE);
Since i'm in an anonymous class and I've read that it's not a good idea to pass the whole context to classes, I wondered about two things :
1 - Is there another way to check internet connection without the Context ? 2 - Why in Android internals make it necessary to have the context just to check if the device is connected to internet ?
I have a custom view that works fine and I'm trying to get gestures into it. The most common technique I see is to add XML, such as this (from Android docs.Can someone point out my errors, suggest a better way that will allow me to get gesture callbacks and/or suggest diagnostic approaches?

View 1 Replies View RelatedI'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.
When I tried to create a ViewFlipper inside a class which extends LinearLayout, its throwing an exception
"java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()".

But when I create the ViewFlipper in a class which extends Activity, its working normally. What may the reason?
I'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...
