Can't call function from within onOptionsItemSelected
- by Kristy Welsh
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.
