Find Bugs eclipse plugin Unchecked/unconfirmed cast from android.view

I want to test my application using Find Bugs plugin for eclipse and I get this kind of bug:

Unchecked/unconfirmed cast from android.view.View to android.widget.EditText of return value

and code part is this:

((EditText) findViewById(R.id.EditText)).setEnabled(true);

So what is the bug? I tried to write like this:

if(findViewById(R.id.otherEditText) instanceof EditText)
    ((EditText) findViewById(R.id.otherEditText)).setEnabled(true);

But there is no result , the same bug is appeared

The problem is that FindBugs cannot be sure that the method call gives the same result every time. So it must assume that the result is different in the test and where the cast happens.

In order to give this information to FindBugs, try this:

  • Assign the result of findViewById(R.id.otherEditText) to a temporary variable without casting.
  • Then do the if and the cast using the variable.

This way, FindBugs can see that the value checked and the value used are the same.
