Android :: Clone A TextView Rather Than Create One From Scratch?
Oct 4, 2010
My app creates a lot of TextView objects and this turns out to be really slow. A look at the traceview output reveals that the bulk of the time is spent in the TextView methods that grab all the default parameters from /res and /util. The thing is, all my TextViews share 99% of these parameters. Is it possible to clone a TextView rather than create one from scratch? If not, what about if I created a pool of TextView objects and reused them?
Just to give some context, I'm generating a spreadsheet to show some data provided from an online source and the spreadsheet can be as big as 20 columns by 50 rows = 1000 cells, each with a TextView. It takes about 25 seconds just to create 1000 TextViews on my Moto Droid.

I know all about get menu references on callbacks, but I want to create one from scratch - as in
new ContextMenu() or new Menu() (I know that's an interface, so obviously that won't work).

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();
[Code]...

I have a Textview with location:
eg. "Mountain View, CA"
What I want to achieve is to create this text to act like a Link - color,underline, focusability etc.
This link doesn't need to direct anywhere - surrounding view has attached onClick listener that fires google maps intent.

I would like to create a TextView that would contain a single link, e.g. google.com. After click it would open google.com in browser. I found a way how to do it, but it's a bit slow, can this be done more efficiently? Now I use this code:
TextView link = (TextView) findViewById(R.id.link); link.setText(Html.fromHtml("<a href="http://www.google.com">google</ a>")); link.setMovementMethod(LinkMovementMethod.getInstance());

I defined some complex AnimationSet in xml and would like to run it on several Views (View.startAnimation()). i cannot just create one instance of this AnimationSet (using AnimationUtils.loadAnimation()) and use it as parameter of View.startAnimation(), so i have to create several instances of this AnimationSet. since loading it from xml is rather slow operation, is there a way to load it once and then clone it when needed?

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 have a Samsung Q1 tablet PC installed in my car. I just got a Droid and like its GPS software better than any designed for PC I have tried. Is there a way I can clone my Droid screen onto my Q1? Sort of like the remote desktop apps out there but they all seem to be designed to access the PC via the Droid.
I don't care about controlling it via PC, I just want the GPS screen on my 7 inch screen instead of the 3.8 or whatever the Droid is. I have been researching installing Android onto PC but it doesn't sound like it works too well just yet.

I have a class which has implemented Parcelable. Can I do something like the following to create a new instance of a class?
found this from the following q: http://stackoverflow.com/questions/1626667/how-to-use-parcel-in-android
This is working ok, I can go with this but it is extra code, not sure if there's a shorter way to do it (other than properly implementing a copy constructor...)

So I got my first Android phone, this Evo 4G last week. It's really great and I love it but I have all kinds of crazy stuff going on, triple contacts, facebook contacts, my gmail account contacts, my business google apps contacts, just things seem kinda out of control since it's my first Android phone. So I'm thinking about just starting with a clean slate, now that I know a lot more about what the phone can do, which calendars to you, which sms program, other apps that are must-haves. Is this a good idea? Will it do anything to my SD card, which has all of my apps backed up?

Is there a way to clone a Tablet to an image, and then load that image to multiple tablets?The Tablets would all me the same model of course, if this was a computer i would use a program like clonezilla. Also The tablets are a Samsung Galaxy Tab 10.1 and do not have micro sd card slots. Can not use WiFi to create or restore clone/image with a cloud service(connection is poor and unreliable). Device can not be rooted.

App that tunnels my text and whatsapp message to another android device.
Like this scenario:
3G --> message ( whatsapp or text ) --> android device 1 ( proxy ) --> encrypted -->WIFI ( internet ) --> Android device 2
This way i can send and receive messages trough another android device that acts as an secure message proxy.

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.

This questions comes as my team is about to under-go development for a mobile app targeting iphone, android and qt. We aim to complete the iphone version first, and then port to android and qt, and it would be great to know any tips or ideologies to grasp/employ from the outset, that would make the porting process as seamless as possible.
I'm sure there a few of you who have completed their iphone version of an app first, and then gone about developing an android version. I am keen to know any of the hurdles that you encountered, or things you wish you knew from the start.
More specifically, the app we are making will contain forms and some visuals(charts)

My question is almost exactly this question:
Clone textview to append it to a ViewGroup
However, I was inflating a view, and then attempting to clone it at the object level for performance reasons (I don't want to parse XML every single time), so that answer doesn't help me. View.clone() is protected and it apparently doesn't have a copy constructor. Is there any way to do this?

I have this problem with my iphone 4s clone (like these two: Replika iPhone 4S MTK6573 Android 2.3' - Root Etme and MTK6573 Android 2.3.5 Fake iPhone 4S'in Orijinal ROM Yedeğini Almak in youtube). I installed an app, the iphone clone locker. Then I open it, it worked for few minutes but when press the home button, it asks me if what i'm going to use, that app or the default one. I click the default(accidentally). But it suddenly shuts down! and wont work til now.
whenever i press the power button to open it, i have this logo. But it keeps on flashing only. It only blinking until it runs out of battery.I haven't rooted it before that happened. I did everything. Holding the power button+home. Taking out the battery. But no luck. Still see the blinking logo.I don't what happened, did i bricked my phone? Or it just crashed?

Just rooted my Evo w flipz Fresh 1.0.1. All is wonderful. I have an 8GB micro SD card at the moment, and this ROM comes configured to install apps to the card (vs. internal memory) using apps2sd. The card has been partitioned to have a 32MB swap, a 768MB ext2, and around 6GB for FAT32. So the card is now _very important_, as apps and prolly extensions from the OS are now on it. I'd like to backup to an _exact_ copy of the card. Is there a way using command shell or some other utility to clone/mirror? I would actually like to upgrade to a 16MB card, and keep everything just as it is on my 8MB card (i.e. copy same configuration and end up w 14GB of storage).

I was reading about the scratch test (keys, screws, razor, etc.) and how they didn't scratch the screen, but how sand might. I am curious, is it sand specifically, or anything like it, such as dust or lint? Could things like that scratch glass? In other words, can the screen be scratched by slipping the phone into an otherwise empty, clean pants pocket?
