ERROR No package identifier when getting value for resource number

Question

Both activities are in the same package

Second activity uses second layout file

setContentView(R.layout.main2); 

Errors on this line in the Second_Activity.

EditText text1 = (EditText) findViewById(R.id.EditText03); 

Here is the layout file for the Second_Activity.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical" >      <LinearLayout         android:id="@+id/LinearLayout01"         android:layout_width="wrap_content"         android:layout_height="wrap_content" >          <TextView             android:id="@+id/TextView01"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="Answer Is : " >         </TextView>          <EditText             android:id="@+id/EditText03"             android:layout_width="wrap_content"             android:layout_height="wrap_content" >         </EditText>     </LinearLayout>      <Button         android:id="@+id/Button01"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:onClick="onClick"         android:text="Calling an intent" >     </Button>  </LinearLayout>

Answer 1

I got this same error message when I tried to use TextView.setText passing a char instead of a String. This makes sense since the char would be promoted to an int which meant that I was really calling the

TextView.setText( int resId ); 

And since there wasn't a resource with that value, it wouldn't work.

Answer 2

face with the same error

finally i found its not a error due to your xml layout

somewhere in your code set TextView.setText(int)

try TextView.setText( Integer.toString(int));
