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 a multiple of Activity.
In many sites or books, but there are articles on additional Activity, which articles also, not 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 of 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 would like to introduce as much as possible take-home gait.
I add 1.Activity java file of the (Class).
Than the Package Explorer, the Android Project you want to add the Activity, src-> at the first made package, right click.
And, New-> When you select the Class, will open 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.
Since 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.
The red frame portion of the image, perhaps because first you would have been displayed as "java.lang.Object", to clear.
If there is an "Activity" from the list below I choose it.
(You have to inherit the mere Activity class as an example, you 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 a class that inherits from the code later, it's okay to accidentally here. )
If you do not, as in the bottom of the image, in the text box, and if we enter A cti ···, because you will have been narrowed down the list in conjunction with the character, it is useful to Once you have become accustomed.
Then, press OK, and press the Finish button when you return.
This, java file is generated completion.
Describe the declaration of 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.
As the contents of XML, it is a form such as the 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 such as the following.
Lower left corner 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 is if you have already added the Activity, so there is also a case where there is a radio button as shown below, please select the first one of the choices at that time.
In the list box below, because there is that "Activity", I double-click on it. and (can be OK to select)
Then, like the red frame the lower portion of the image, the Application Nodes, I think that element called "Activity" has been added.
While selecting this, I will look at the place called "Attributes for Activity" on the right side of the screen.
I think that it is becoming similar to the image below.
There is that "Name" in there, and press the right-hand side of the Browse button to open 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 up here.
After that, add the definition of the layout, will promote the implementation of the Activity class, you will carry that.
