findViewById Error cant find id in XML

Question

I cant find out why my findViewById is not linking to the XML file and it is driving me nuts. The is is in the XML file but it is still not Finding it in the java MainActivity file.

here is my XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<EditText
    android:id="@+id/editCentimeters"
    android:layout_width="wrap_content"
    android:layout_height="27sp"
    android:layout_alignLeft="@+id/editInches"
    android:layout_alignTop="@+id/textCentimeters"
    android:ems="5" >

<Button
    android:id="@+id/buttonConvert"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/editInches"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="98dp"
    android:text="@string/convert" />

And here is my Java

EditText etCentimeters = (EditText) findViewById(R.id.editCentimeters);
Button buttonConvert = (Button) findViewById(R.id.buttonConvert);

Answer 1

I was facing the same issue. Just comment out the line which is throwing the error & BUILD the project once. Intellisense (ctrl + space) then will show you the IDs.
