Android :: Relative Layout Unit Test Setup
Mar 20, 2010
i'm trying to write an unit test for my Android's RelativeLayout. Currently, my testcode setup is as follow:public class SampleRelativeLayoutTest extends AndroidTestCase {private ViewGroup testView;private ImageView icon;private TextView title;@Overrideprotected void setUp() throws Exception {super.setUp();
// inflate the layout
final Context context = getContext();
final LayoutInflater inflater = LayoutInflater.from(context);
testView = (ViewGroup) inflater.inflate(R.layout.sample_layout,
null);
// manually measure and layout
testView.measure(500, 500);
testView.layout(0, 0, 500, 500);
// init variables
icon = (ImageView) testView.findViewById(R.id.icon);
title = (TextView) testView.findViewById(R.id.title);
}However, I encountered NullPointerException with the following stack tracejava.lang.NullPointerException
at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:427)
at android.view.View.measure(View.java:7964)
at com.dqminh.test.view.SampleRelativeLayoutTest.setUp(SampleRelativeLayoutTest.java:33)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154)
at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)
What should I change in my setUp() code to make the test run properly ?

I am having an issue trying to setup a scrollview with a relative layout.
Here is my layout file
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
[Code]...
The scrollview is working correctly but the relativelayout is showing up correctly in my graphical layout view but I can't seem to see it on my phone or emulator. I want it to be displayed all the time and not a part of the scrollview. I just don't know how to fix it.
Here is how I would like it to work

I'm writing an Android JUnit test and want to copy/reset a test fixture file (it's an SQLite database file.) If I were within the main application, I know I could just place the file in the assets directory and use getResources().getAssets().open(sourceFile).However, this API appears to be unavailable from the ActivityInstrumentationTestCase2 class.Is there an easy way to copy a file over from the testing PC, or should I just keep a fresh copy of a test fixture on the device and copy it over a temporary file?

I am using ActivityInstrumentationTestCase2 to do some test for an activity. I get a button in the setUp() method like this: protected void setUp() throws Exception {super.setUp(); act = getActivity(); btn = Button)act.find ViewById ( R.id.bike_button ); // this button has been defined in layout} Then I use this button to perform a click in a test method like this: public void testBikeButton(){ //click the bike button btn.performClick();}

I'm working on a school project and I'm researching testing possibilities for Android applications. On this page: http: // developer . android . com/ resources / tutorials /testing /hello android. Google writes about a unit test. Is this really a unit test? A Unit test will not integrate all classes and will not test in his context. So my opinion is it is not a Unit Test but an Integration Test.

Sorry if this is a bit of a vague question, however im struggling to find a single solid example on how to do unit testing (isolated testing) with Android. So one project contains models and logic, then another project contains tests for said library. There is no front end or UI, so I want to do the bare minimum to just be able to test that my methods all work in isolation.

I just switched the way my Android project is being built and non of my unit tests work any more...I get errors like WARN/dalvikvm(575): VFY: unable to resolve static field X in WARN/dalvikvm(575): VFY: unable to find class referenced in signature These errors only come from my Unit Tests, where classes defined in it can't even see other classes defined in the unit test. Before each project had it's own directory with copies of the 3rd party jar files. I've read around that Dex does weird things with references but haven't been able to figure out how to fix this problem. Is there a better way to do this? I would love to see an example of a large Android workspace where there are multiple projects, jar references, etc.Is it possible to fix this with an Order/Export tweak ?

I my main app and tests are organized like this (standard from "android create project"): AndroidManifest.xml assets/ main app asset files src/tests/AndroidManifest.xml -- uses <instrumentation> to point to the main app assets/ -- test-specific asset files src/ Writing test cases with AndroidTestCase, I'd like to load asset files from the test-specific assets/ directory, not from the main app assets/ directory. How can I accomplish that? The normal way to load an asset would be getContext().getAssets().open ("foo.txt"), for assets/foo.txt in the main app. I assume I just have to somehow change the Context or the AssetManager to point to the test- specific assets directory, but I don't see any way to do that. I have looked into the tests/bin/MyApp-debug.apk to confirm that the test assets are in there. Now I just need a way to access them.

I am trying to unit test a class that does SAX parsing and creates an object.This class takes a string as a parameter representing the URL of a document on the internet, parses it and then creates an object based on the contents.I don't want to have the unit tests actually access the network, so I'd like to have a few test xml files to parse. However I can't figure out how to access them from my AndroidTestCases. I don't want to include the test files with the actual application, I want them in the test project (it's a separate project, as is the norm for Android tests from what I could gather - due to the need to have a custom AndroidManifest.xml, for one).One way would be to put the XML files in the test project's assets directory, I can read them using getContext() .getAssets().open(filename) into an InputStream in the test case, but my class expects a URL string. I'd rather not have to provide an InputStream to this class instead of the current URL string. I can test just the parsing by making two methods, one that takes a string and one an Inputstream, and test the second, but how can I then test the one that just takes a string?How should I design my class and or tests to circumvent this problem?

Being able to write Android apps in regular Java is a huge win. However, I am confused about unit testing Android apps. Many of the 'best practices' seem to boil down to 'split your business logic off, and test it separately using JUnit'. This is great as far as it goes. And I understand that truly testing the UI will require firing up the emulator. But it seems there is a category of UI tests that I should be able to run without the emulator. The various Mockxxx classes seem to be going a long way towards this. But why (oh why oh why!) do they all. throw new RuntimeException( "Stub!" ); in their constructors? I can understand them doing this in their METHODS (then I could subclass them as needed) but why their constructors? I cannot stop this functionality so I cannot do (limited but useful) UI tests such as public TextView createTextView ( Context context ) {return new TextView( context );

I am creating an EditText object which i then try to reference in a unit test. what is the best way to add a new 'id' to R.id for this dynamically created object so that i can later reference it via findViewById() in the unit test?

I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

I approached this problem as an oh hey that's not too bad, I can write a bunch of unit tests, and I have been keeping my suite green. However as things get more involved continuous integration and testing is a great great thing to have. And then I saw oh Android has emma integration as well awesome ... and then that's where it get's iffy. So I setup Hudson and have it call the coverage target of the ant build.xml that the android executable in the sdk can generate. And then it hits me. adb -s <emulator> shell am instrument -w ... will never return a result code that is not 0 ... because adb technically exited cleanly and usually will regardless of how the shell command that executed did..............

I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler?

I'm reworking some of my layouts to use Relative layout. I have some building blocks which I'd like to reuse. The problem I seems to have with the include of the layout and position other layouts out of this include. Example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height=wrap_content"

I need to implement a screen containing a list of blocks one below the other. Each block will contain mutiple superimpose elements (Images, text) for which the relative position needs to be specified with respect to the top left corner of the block.
For creating the list of blocks i have used listview. For each block i tried to use relative layout.This works ok when the phone is in landscape mode and absolute position is specified relative to left edge of the phone. But when the phone is put in the portrait mode the layout gets distorted.
1) What layout can be used for this scenario?
2) Can relative positions be specified in terms of percentage of screen width/height instead of pixels?

I'm attempting to add four controls to a layout; <label> <text> <seek> <radio> I want the seek widget to occupy all the available screen space between the edittext control and the radio control. However if I give it the value android:layout_width="wrap_content" only a small seek control is displayed and if I set the value to fill_parent it overwrites the radio control. I would have thought there would be a mechanism to occupy the free space between the text and radio controls dynamically.

I have a button on a relative layout that hugs the buttom of the parent, but since there is not much above the button, the height of it is massive and extends to the object above it.What kind of code can I use to make sure the button stays at a normal height while still hugging the bottom of the parent?

In a RelativeLayout I have a Button to the right of a TextView. The problem is that the text view gets squished to the left of the screen.I want the Button to be squished to the right and the TextView take up all the remaining space.I can't use 'Fill Layout' on the TextView because the button then gets removed from the View completely.

I have a relative layout built from XML.I am capturing the onTouchEvent.When I touch the screen anywhere except over the TableLayout or ImageButton
the MotionEvent.ACTION_DOWN and MotionEvent.ACTION_MOVE
events work fine.
how to make the onTouchEvent() work on the TableLayout and ImageButton views?
The purpose of the exercise was to have a drag method working over the relative layout,no
Maybe manipulating the layout_margin values? I was contemplating a transparent canvas overlay but haven't figured that out yet.

I have the following layout in my xml file:
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout android:id="@+id/logoLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
-- some images </FrameLayout>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical"
android:layout_below="@+id/logoLayout">
Button 1
Button 2
Button 3
Button 4
