(GO). NET programmer moved to Android second---kind

The previous article says how to build an Android development environment, this one we will kind a bit,

Complete our first Android app app.

I'll start with the new project.

First open Eclipse, select File--new at the top (new)--select Android application Project.

, the above is some name, you can fill in, the following are more important, according to different needs to choose different versions of the SDK, here I choose to start from 2.2. When you are finished, click Next.

If you want to change the project path to the path you have made, you can remove the Create project in Workspace and select the location you specified, and continue to the next step.

To this page is some of the log design, specifically I do not say, each option can try, here I choose the default, in the next step.

For advanced Android engineers, this step depends on the choice of requirements, we choose the first default. Continue to the next step.

This step does not need to control, click Finish. (If you want to change the name of the start page, you can change the layout Name column to your own start page)

Entering the code page, we can clearly know textview this control is similar to the lable,android:text in. NET, which is what character is displayed in this textview.

For the sake of insurance, we don't change it first, run first, see what the effect is.

Select the second red box to run, why the first worm-like red box is also circled to choose, because this is important, if you want to debug the trace,

Run with the worm (Dbug), and if you have confidence in your application, run it directly in the second way.

Run OK, then we can let go to change its code, the target lock just the code page.

What are we going to change? I would like to change the text content.

At the bottom of the text there is a button that can be clicked to pop up a custom message.

Well, let's do it if you know.

Here with the red box circle is my new content, everything is done we run the program bar.

After clicking the button, a custom message pops up, which is what we want.

To this end, we kind is also an end, if it is not enjoyable, you can boldly try. Get familiar with Android controls and trigger mechanisms.

In the next article I will share with you the most common and important "login interface" of the project.

If it is not right, we can say that we can learn from each other. If you want to discuss in real time, add the QQ group I created:
