Android :: Arranging TextView Objects On Screen
Jul 28, 2010
I'm using textview objects to hold labels such as Score, Level etc on my game screen but they don't seem to be displayed where I want them to be. I understand about view hierarchies (parents, children) and am using the gravity tags in the XML layout file but it doesn't seem to have any effect. Could someone just quickly provide a guide to positioning a textview object on the screen, and also linking it in the code so that its contents can be pro grammatically controlled (I believe this would by done via =(TextView) findViewById(r.id.resourcename))? Code...

The FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................

I have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.

Is there any way for an Android application to retrieve some sort of Collection object that contains references to all of the GUI elements which are currently on the phone's screen? This could be very useful for testing purposes and so on. If I have overlooked a well-known class or library, please let me know.

I am finding that performance degrades after one or more screen rotations, and I presume that this is likely to be because an App's main Activity is destroyed and recreated each time the screen is rotated and that my app must be leaking memory when that happens.I have read that, contrary to what one might expect, not all the objects created by an app's main Activity (or in classes called by that Activity) are destroyed when the activity is destroyed. Specifically, I think I have read (although I can't now find where) that if the View uses a large bitmap member object then the Activity's onDestroy() method should be over-ridden and the bitmap should be explicitly recycled.Are there other objects that need to be destroyed or removed when the Activity is destroyed? What about Listeners? Is there a comprehensive tutorial or guide on this subject?

Fellas, I've got another question about my X10 Mini.I've been downloading many apps from Android Market and there are so many good ones, but also some others pretty awful.The thing is that unninstalling some apps from the phone leaves me gaps in the menu.I've got pages of the downer menu with only six icons, when the space allows 9. How can i re-arrange the icons to put them in order?Is there an option in the phone as it comes, or do I have to download an app from the market?

I've a textview I want to span almost the length of the screen, then 2 buttons at the bottom.
Right now I'm using a relative layout with a textview and two buttons and I can almost get it the way I want but the only thing is the textview isn't as long as I want it. I want it to be as long as necessary for whatever handset is using it. So a constant pixel amount is out.

I have an Android TextView where the view itself is limited to four lines.If the text exceeds this limit I want the end of the view to end with something like.<-- to notify that there is more text here so you can click and open in full screen for example.Not just suddenly stop in the middle of a sentence. Is there a quick fix for this?

I noticed that it is not possible to specify a percentage value for maxWidth.
What is the best way around this?
For example, in the layout xml, is it possible to get a handle on the screen width and apply some kind of arithmetic to it (e.g. maxWidth="(60 * @screenWidth) / 100px")
Also would this approach mean the maxWidth would be automatically recalculated on orientation changes?

I am developing an application in which the layout is independent of screen resolution.
Now my problem is that in TextView the textview layout does change itself when the resolution of screen changes but the size of text remain same.I want that when the resolution is high, according to that the text size should also adjust itself(i.e. text size should be changed).And similarly when resolution is low the text size should also shrink.But here when i reduce Y-AXIS to an extent the text vanishes.I will really appreciate any answer.

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.

I 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.

I'm trying to create a textView in the parent activity onActivityResult but the textView does not appear. There is an ImageView that takes up the whole parent activity. I can create a textView and place it, and it should go on top of the imageView?
In the parent class:
[HIGH]private void addClothes(int menuId) {
Intent chooseClothesIntent = new Intent(this, ChooseClothesActivity.class);
chooseClothesIntent.putExtra("menuId", menuId);
startActivityForResult(chooseClothesIntent, 1);
}[/HIGH]
[Code]...
then in my new activity:
[HIGH]@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
try {
ClothingItem ci = mListContents.get(position);
String imagePath = ci.getImagePath();

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.

I am new to Android development. I want to know how you all manage objects. For eg we make object as A a = new A(); and then manage that object. But, here, we call A.class; My concern is that i don't want to call on Create(),nor do i want to push UI screen I just want to make 1 static object for 1 screen;and want to manage it throughout my application. that is, instead of calling A.class; can i call A a = new A(),and manage that object without pushing,and whenever i need i push that screen. Is there someway?
