public boolean onOptionsItemSelected(MenuItem item)
{
//check selected menu item
switch (item.getItemId()) {
case R.id.exit:
this.finish();
return true;
case R.id.basic:
Difficulty = DIFFICULTY_BASIC;
Toast.makeText(YogaPosesActivity.this, "Difficulty is Basic", Toast.LENGTH_SHORT).show();
SetImageView(myDbHelper);
return true;
case R.id.advanced:
Toast.makeText(YogaPosesActivity.this, "Difficulty is Advanced", Toast.LENGTH_SHORT).show();
Difficulty = DIFFICULTY_ADVANCED;
SetImageView(myDbHelper);
return true;
case R.id.allPoses:
Toast.makeText(YogaPosesActivity.this, "All Poses Will Be Displayed", Toast.LENGTH_SHORT).show();
Difficulty = DIFFICULTY_ADVANCED_AND_BASIC;
SetImageView(myDbHelper);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
I get an error when I call the SetImageView function, which was defined out of the OnCreate Activity. Can you not call a function unless it was defined inside the OnCreate?
I get a nullPointer Exception when calling the function.
If you define your SetImageView (myDbHelper) inside your Activity (and outside of onCreate()), it should be OK to call it like you did.
If you are getting a nullPointer Exception, the reason might be that myDbHelper is still null. Check whether this is true.
By the way Java suggests we lower case for the first letter of a method or variable, and use upper case for Class.
Sorry I can not comment because I don't have enough point, so I have to answer directly even though I don't have all the info. If you post more code and logcat info. I will revise my answer.
