The app, I want to add the Activity, approach?
When you add the Android Project In Eclipse, I think you are the first java file of Activity to start to be generated.
Depending on the Android app you want to develop, there will be if you want to have more than one Activity.
In various sites or books, but there are articles about additional Activity, which articles also, good enough confusing additional really the first step, I think.
I I hope people of intuition, you will find in it.
Such procedure, compared to the way of processing in the program, or would not be where I want you to tell me take-home gait, if possible?
With that said, the Activity additional steps using Eclipse, and I will try to introduce as much as possible take-home gait.
I want to add 1.Activity java file of the (Class).
Than Package Explorer, the Android Project you want to add the Activity, src-> at the first made package, right-click.
And, New-> If you select the Class, opens the New Java Class window.
I enter any of the class name in the "Name". (Red frame portion of the image)
This is the java file name.
There is a button labeled "Browse" best on the right side of a place called "Super Class", I press. (Brown frame portions of the image)
This opens the Supperclass Selection screen.
In red frame portion of the image, perhaps because the first I think is displayed as "java.lang.Object", clear.
If there is a "Activity" from the list below I choose it.
(You have to inherit the mere Activity class as an example, you will need to inherit the ListActivity and MapActivity. Depending on the case, please choose a class that inherits.
Of course, so you can it is to change the class that inherits later from the code, it is okay to accidentally here. )
If you do not, as in the bottom of the image, in the text box, and if we type A cti ···, because we will be narrowed down the list in accordance with the character, it is useful to Once you have become accustomed.
Then, press OK, and press the Finish button when you go back.
This, java file is generated completion.
Describe the declaration of the added Activity in 2.Manifest.xml.
Add a java file, only the implementation, Activity does not work.
In Manifest file, you need to add the declaration of Activity.
The contents of the XML, it is shaped like a following. (If you want to add the Activity that xxxActivity.java)
<Activity android: name = "xxxActivity"> </ activity>
So, we will explain how to set up in Eclipse.
First, as shown in the following image, I will open the AndroidManifest.xml in Android Manifest Editor. (Since normally associated, double-click OK.)
And, I will open the Application tab. It is a screen similar to the following.
The bottom left of the screen section (image red frame part of the above), because there is that "Application Nodes", I press the individual Add button. This will open a screen similar to the following.
※ When it if you have already added the Activity, so you may radio button as shown below, please select the first one of the choices that time.
In the list box below, because there is that "Activity", I double-click it. and (can be OK to select)
Then, as shown in the red frame the lower part of the image, the Application Nodes, I think the element of "Activity" has been added.
In the state in which you select this, I will look at the place called "Attributes for Activity" on the right side of the screen.
I think that it has become like the following image.
There is that "Name" in there, and press the right-hand side of the Browse button opens a screen similar to the following.
To image red frame part of the open window, there is a text box.
Here, I I'll do type in the class name you just added.
It is OK even does depend from the list below.
In, you're done, press OK, and if you save the Manifest.xml.
Now, it is complete with respect to additional Activity.
In this article, you as the end in the procedure description of up to here.
After that, add the definition of layout, to advance the implementation of the Activity class, you will carry that.
