The app, you want to add an Activity, but the way?
If you add a Android Project in Eclipse, java file of Activity that comes up first is not it is generated.
Depending on the Android app you want to develop, there will be if you want to have more than one Activity.
I thought in the various sites and books, has an article about adding Activity, but also any article, and, confusing the first step of the additional really good enough.
Human intuition is good, but I'll see it in the.
Such procedure, I think where it compared to the way of treatment in the program, I want you to tell me take-home gait, if possible?
I think with that, that it will introduce in the take-home gait as much as possible, the procedure of adding Activity using Eclipse.
I add java file 1.Activity of the (Class).
From the Package Explorer, at the package that made of Android Project you want to add an Activity, the src-> first, right-click.
And, if you select New-> Class, New Java Class window opens.
I enter the class name of your choice in the "Name". (Red frame portion of the image)
This is the java file name.
Because there is a button labeled "Browse" to the far right of a place called "Super Class", I press. (Part of the frame the brown image)
Then, Supperclass Selection screen opens.
Since I think the red portion of the image frame, the first listed as "java.lang.Object" You will probably clear.
I choose it if there is an "Activity" from the list below.
It is an inherited mere Activity class (examples, but you must inherit the MapActivity and ListActivity. Please choose a class that, as the case may be, inherit.
So can you change a class that inherits from the code later of course, it is all right even by mistake here. )
If not, then, as the image below, in the text box, and if I type A cti · · ·, listing, so will have been squeezed together in the character, it is useful to Once you have become accustomed.
Then, press OK, and press the Finish button when you return.
Now, java file is generated completion.
Describe the declaration of the Activity that you added to the 2.Manifest.xml.
Add the java file, the only implementation, Activity does not work.
The Manifest file, you need to add the declaration of the Activity.
The contents of the XML, it is the following form. (If you want to add a Activity called xxxActivity.java)
<activity android:name="xxxActivity"> </ activity>
Now, we will explain how to set up in Eclipse.
First, as shown in the following image, I will open it in the Android Manifest Editor AndroidManifest.xml. (Because it is associated with, usually, OK. By double-clicking)
And I open the Application tab. It is a screen similar to the following.
Because there (image red frame portion above) screen bottom left corner, it referred to as "Application Nodes", I press the Add button here. Then the following screen will open.
※ When it is if you are adding a Activity already, it is also possible that there is a radio button as shown below, please select the choice of the first one at that time.
Because there in the list box below, it called "Activity", I double-click on it. and (can be OK to select)
Then, I think as the red frame part of the image below, the Application Nodes, an element called "Activity" has been added.
While selecting this, I see the place on the right side of the screen called "Attributes for Activity".
I think that it is as shown in the following image.
Because there there's the "Name" and press the Browse button on the right side, the following screen will open.
To image red frame of the window that opens, there is a text box.
Here, I'll do I devoted the class name you just added.
It is OK It does depend from the list below.
In, you are finished press OK, and if you save the Manifest.xml.
Now, you are finished for additional of Activity.
In this article, I will end with the description of the previous steps.
After that, you will carry by adding the definition of the layout, and, proceeds with implementation of the Activity class.
