Android :: Can Animate - Scale - Just One Component Of Android Layout And Have Layout Update During Animation

Nov 10, 2009

Imagine I have a toolbar implemented as a horizontal LinearLayout as follows:

[___Button1____] [___Button2___] [___Button3___] [___Button4___]


When someone clicks on Button2, I want the toolbar to change to:

[___Button1____] [___________Button2___________] [___Button3___]

The toolbar should transition from the first state to the second state through a smooth animation. I would like to use a scale animation on Button2, and while that is happening, Button3 and Button 4 should move to the right (while the animation is going on). At the end of the animation (or maybe during), I will fade Button4 out.

Question: How do I achieve an animation of the layout of the toolbar such that only one component (i.e. Button2) is being scaled while the others are not being scaled - the layout is simply updated during the animation of Button2.

I looked at LayoutAnimationController, but it does not appear to allow me to either:

1. specify different animations for the different components, OR

2. indicate that only animate one component and don't animate the others.

I can't scale the entire toolbar because that distorts Button1/3/4 which I don't want.

Android :: XML Layout Of Custom Component

Jul 9, 2010

I have created a simple class named Panel which extends the SurfaceView class and does some drawing in the onDraw method. When I use it from the code it works fine. For example this works as expected:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new Panel(this)); ....

However when I try adding this component from an xml layout the program crashes:
XML file (main.xml):
<?xml version="1.0" encoding="utf-8"?> <org.anddev.Panel android:id="@+id/panel" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"/>

Code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);....

Error msg: Sorry!
The application Test (process org.anddev) has stopped unexpectedly. Pleas try again.
I can not figure out why the same class works when created in one way and doesn't work when created in another.

Android :: Droid Layout : Is Reusable Component UI Possible?

Feb 18, 2010

I'll preface this with, I've just started learning Android so be gentle.
I come from an ASP.NET / Silverlight background so I was looking for something along the lines of controls.

I want to reuse a layout (a ListView item template) in other layouts.

Such that in my other layouts I can just add <myListItem /> to show it.

Is this, or anything like it possible? or are there better ways?

Android :: Find View Returns Null For Custom Component In Layout

Nov 7, 2009

I have a res/layout/main.xml including these elements and others:

<some.package.MyCustomView android:id="@+id/foo" (some other params) />
<TextView android:id="@+id/boring" (some other params) />
In my Activity's onCreate, I do this:
setContentView(R.layout.main);
(TextView) boring = findViewById(R.id.boring);
// ...find other elements...
MyCustomView foo = (MyCustomView) findViewById(R.id.foo);
if (foo == null) { Log.d(TAG, "epic fail"); }

The other elements are found successfully, but foo comes back null. MyCustomView has a constructor MyCustomView(Context c, AttributeSet a) and a Log.d(...) at the end of that constructor appears successfully in logcat just before the "epic fail".
findViewById() returns null for custom component in layout XML, not for other components. Why is foo null?

Android :: Layout - Status Bar Space Remains Empty || - Animation

May 12, 2010

On my emulator this seems to work fine. The status bar disappears and the empty space is filled with the content view. However on my Nexus One this sometimes works and sometimes the empty space remains empty/black. I tried to counteract this, but my naive approach wasn't fruitful:

Android :: Unable To Open Both Main.xml Files / From Layout & Layout-land At Same Time?

Aug 14, 2010

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

Android :: Inflate Complex Layout And Add To Another Layout?

Jul 29, 2010

I'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?

Android :: Animation - Animate An Imageview Across Several Layouts

May 12, 2009

I want to be able to make an imageview move from point a to b while going through several different views. For example, say I have a table layout, is there any way an imageview can move from the topleft cell to the bottomright cell? Everything I tried seems to indicate that an imageview will only be shown in it's own container - none of it's parents, siblings or children will show it. Is that correct? is there any way around it? like creating an overlay or a transparent canvas on top of the entire thing so I can do it?

How To Properly Use Layout-large And Layout-land

Sep 26, 2012

I have 5 layout folders. layout, layout-small, layout-normal, layout-medium and layout-large.

My app is heavily image based. As a result I have created the proper images. mdpi, hdpi and xhdpi. I don't think I need to worry about ldpi since screens are only getting bigger.

With this in mind and the need for me to now create a good landscape layout for all my pages, how do I go about this? Is it simple layout-land? No need for large/small/normal again right?

Considering that I've got all my hdpi and xdpi images do I even need layout-medium, layout-large and layout-normal? Because the images will be adjusting themselves based on screensize surely I can use one layout and have that work for all screens..?

It's all getting very confusing now that I'm trying to add a landscape view to my app. It doesn't do it very well at the moment so I will probably have to design a landscape friendly layout so I can understand that I would need to rebuild all my layouts for this particular use (We're talking about 100 layous here but oh well, I can manage it. )

Android :: Android - Layout - How To Create A Header-content Layout

Jan 4, 2010

How do I go about creating the following layout in Android?

I want a "header", that is, a header that stays the same at all times. The only thing that should change is the area below the header.

Think of it as a webpage, where the content-area is where its all happening =)

+--------------------+
| H E A D E R |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+

Sure, its easy enough to create a LinearLayot, add a View on the top and then another view below that - tada! But what Im after is how you "set up" or design the project so its easy to just change whats in the Content.

What I really would like is to be able to "swipe" (see here) the area and then just "roll in" a new View/thing in the Content-area, but keep the same header.

While coming to the middle of the screen, its size should increase(i.e. scaling should take place). Image should not go back to its original position. It should be placed at the middle of the screen itself after the animation.
