I would like to know which way is the best and why between : - inflate a view from xml - create the view directly. I'm talking about performance.
View 3 Replies View RelatedI'm wondering if it is possible to inflate a layout using a different density value than the default system density. I have a high density layout, which looks good on the Galaxy Tab (1024x600px, hdpi) and I like to use the same layout on another tablet with the same pixel resolution but medium density. The mdpi layout which is used works on the device but the screen just looks really empty and I would prefer to scale things up. So is there a xml argument for scaling the layout, maybe something similar to Bitmap.Options.targetDensity. Or could this be done with a new LayoutInflater class?

View 6 Replies View RelatedI'm trying to create a component using an xml layout file. I defined a layout with some custom attributes. This layout is inflated when user add it inside another layout. My problem is I don't know the parent, so I pass null for the parent viewgroup when I call inflate method. I think that's the reason why I see anything in my view. Do you know how can I do (I don't want to redefine onDraw method because I use existing component). Below my xml layout and my custom class.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">
<ImageView android:id="@+id/img_btn_option" android:layout_width="wrap_content" android:layout_height="wrap_content"/>
<TextView android:id="@+id/txt_btn_option" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_toRightOf="@id/img_btn_option"
android:textColor="@color/font_white" android:textStyle="bold"/>
</RelativeLayout> public class ButtonOptionsView extends View {
public ButtonOptionsView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater li =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout vg =(RelativeLayout)li.inflate(R.layout.button_option, null);
TypedArray ta = getContext().obtainStyledAttributes(attrs,R.styleable.ButtonOption);
((ImageView)vg.findViewById(R.id.img_btn_option)).setImageResource(ta.getResourceId(R.styleable.ButtonOption_image,0));
((TextView)vg.findViewById(R.id.txt_btn_option)).setText(ta.getResourceId(R.styleable.ButtonOption_text,0));}
How could i inflate my custom view using the main.xml file?
View 2 Replies View RelatedI want to dynamically pull in a layout from an external source. As discussed in this thread from September 2009 -
http://groups.google.com/group/android-developers/browse_thread/threa.
I am wondering if the situation has changed since this discussion or if it is likely to change. I understand the need to use pre-compiled xml layouts so if there is an option to dynamically pull in a layout that is already compiled that would be fine. Basically I want a setup where I can change a view layout without an app update. The elements within the view would be fairly static (e.g. there will be 2 buttons call foo and bar that fire fooOnClick and barOnClick). The only work around I can think of is a custom scripting language that allows the definition of views that are created from code. Ideally this would parse the same xml as a standard layout. Obviously this would involve a lot of code and probably be fairly slow.
Button btnFoo = new Button(); btnFoo.setText("foo"); dynamicLayout.addView(btnFoo);
If this is the only option at least the EdsMagicLayoutInflater class would be reusable across projects.
There is this xml file under frameworks/base.

How can I inflate that in my own android application?
I've met a very strange issue that my app will crash if user first switch to landscape, then back to portrait. I found that Activity.setContentView() will throw an inflate exception. It said:
android.view.InflateException: Binary XML file line #29: Error inflating class <unknown>
This crash will happens on Android 1.6/2.1/2.1-update1, but doesn't happen in 2.2 Froyo. In Froyo, everything works fine. If the XML I used is invalid, it should happens every time when I try to inflate. But why it's okay on the first time of running and switching to landscape? This also only happens on some devices. For example, there two HTC G1 with same software installed on it and has the same configuration, one has this issue and the other one works fine.
I have listview and below it have footer to bind more data at footer button click event,the data has been binded well but the problem here is expanding of empty space after click event,when i scrolled to move down,when i reach the last list row by scrolling the footer position is being at same at initially loaded,but here the problem is the list scrolling is applies to this footer layout also when i scrolled down after list row the footer get's moving down,but i need it be after list last row and i also need to know how to scrolling to be stopped when particular condition satisfied.

I have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top
View 4 Replies View RelatedI've successfully created a countdown kitchen timer activity, however my goal is to have an activity that has 3 timers on it that all work independently. I created a separate layout just for the timer itself and moved the timer code into a class and I've used layoutinflater to create the views and then added them into the linear layout for the activity. I get the layouts fine, however there's no functionality. There doesn't seem to be anything that ties the class code to the activity. How should I approach this? Can anyone point me to some working example code?

CODE:...................
We are suddenly unable to install our app on G1 developer phones with 1.6. Works perfectly on emulator. When installing the app we get:
Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE Please check logcat output for more details. Launch canceled!
And logcat:
PackageManage: Couldn't copy package file to temp file.
What does this mean? We checked that there is actually room enough on the phone.. We tried reverting the code to a revision that worked previously, but are getting the same error.
How to play video present in local file system (ex:in res/a.3gp) using VideoView .I am getting error as Video cant be played.Can any one help me in sorting out this issue?

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".
I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.

View 3 Replies View RelatedI'm writing a bitmap editor. Each document consists of about 3 bitmap layers and documents are, at the moment, saved as a custom file with a .bme extension. These files can be converted to standard jpg/png files by rendering each bitmap on top of one bitmap and saving the latter. I need some way for the user to be able to select .bme files they've created already. Is there anything in Android that can make this easier for me? The only option I can see is to write an activity that creates a list view and write a list adapter that looks for .bme files on disk i.e. a copy of the standard "Media Gallery" app that works for my .bme files. The list adapter will either have to generate a thumbnail preview of the image to show to the user or I'll have to package such a preview in the .bme file when they're created. This is the only option I can think of. I thought I'd ask in case there is more Android friendly way of doing this. For example, can you add custom file support to the "Media Gallery" app?
