findViewById do not see the id of my EditText

Question

I've got an EditText():

<EditText
            android:id="@+id/СA_EtFirN"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:hint="@string/CA_EtFirN"
            android:textColor="@color/SSA_TvColor"
            android:textStyle="italic"
            android:layout_gravity="center"
            android:gravity="center_horizontal"/>

So as you see android:id="@+id/СA_EtFirN". Then I've got an Activity.java and I want to define my EditText():

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.contacts);

    Log.i(TAG, "Start definition");
    tv1 = (TextView) findViewById(R.id.CA_Tv1);
    et1 = (EditText) findViewById(R.id.CA_EtFirN);
}

But the id CA_EtFirN is underlined with red. So my program don't see it. Any ideas?

My R.id

P.S With TextView it is OK.

Answer 1

Try to copy/paste id from layout.xml into the code (or vice versa) to be sure you didn't mix cyrillic and latin characters in names.

Answer 2

Try to clean the project and rebuild, sometimes R.java is not updated well.

Answer 3

It is very strange)) if i copy CA_EtFirN it is OK. But if I write the name of id (the same name, I've checked!!!) it is an error)

Answer 4

Check in your java class for import statement android.R if it exists delete that import statement and then clean your project and then run again and comment me about the result
