Android studio and R class

Question

I've a little problem with android studio. Until yesterday I used Eclipse. But today I start to use Android studio. I write a simple layout without errors. Than in src/main/java I write this simple code:

public class MyActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(android.R.layout.activity_my); } }

But I've an arror: "cannot resolve symbol activity_my"

According to me the layout isn't registrated in R.java. How can I resolve this problem? Thanks in advance :D

p.s. sorry for my bad english >.<

Change android.R.layout.activity_my to R.layout.activity_my and import R file — Kunu

Use R and not android.R. Check that the imported R is your.package.name.R.

you should always use setContentView(R.layout.activity_my);.

so replace setContentView(android.R.layout.activity_my); with setContentView(R.layout.activity_my);

USE CTR + SHIFT + o to organize your import statements in eclipse.
