Keeping java code clean

[Hozi Surat]

Hi Jeff,

One of the biggest issue I have when coding Android apps is keeping my java code clean. Does your book explain good techniques for keeping you code organized?

Thanks.

[Ulf Dittmer]

What do you mean by that? Can you give an example of how your code differs when targeting Android compared to other platforms?

Hi,

I haven't done much coding beyond Android development. I have learned a lot from many of the forums along with the book Big Nerd Ranch. All of the examples I have looked at have their code organized differently and I get confused as to whats the best or correct way. For example I see a lot developers write:

btnA = (Button)findViewById(R.id.btnA);

btnB = (Button)findViewById(R.id.btnB);

.
.
.
then add their onClickListener at the bottom of their code.




I also then see the opposite where they put the code in one code block.

I guess I am just confused what are the best practices when organizing your code.

I hope that clarifies my question. Thanks for your help.

Hi Hozi,

Creating and then attaching a listener based on an anonymous class to a view (e.g., a button) is inefficient because it requires a new object to be created each time an Activity callback method (e.g., onCreate(Bundle)) is called. I present a much cleaner and more efficient solution in Appendix C, which is freely available as a 96-page PDF file distributed in the book's code file -- see http://www.apress.com/9781430264545.

All the best.

Jeff

If you interest i am sending my CodeStyle xml file. You can add it in eclipse.
I create this code template based on VisualStudio.

To replacing it follow this path
Window > Preferences > Java > Code Style > Formatter

Coderanch does not allow upload XML file so i paste it here.
Just create a new xml file and put in it.

Creating and then attaching a listener based on an anonymous class to a view (e.g., a button) is inefficient because it requires a new object to be created each time an Activity callback method (e.g., onCreate(Bundle)) is called. I present a much cleaner and more efficient solution in Appendix C, which is freely available as a 96-page PDF file distributed in the book's code file -- see http://www.apress.com/9781430264545.

All the best.

Hi Jeff,

Is this what you are referring to? If so, would you mind explain this a little further as to how it work? I am currenlty working a very small applicaton project and it has 6 clickables on the MainActivity and it just seeems like I have code all over the place.

I guess what I don't understand, if this is what you were referring to, is where this is called or how it knows which button is clicked.

public void doClickOk(View view)
{
EditText et = (EditText) findViewById(R.id.et);
Toast.makeText(Test.this, et.getText(),
Toast.LENGTH_SHORT).show();
}
