(TableLayout)findViewById( null pointer exception

Question

I search for answer all day long, but when i try to get the table layout i am having null. I found info that it may be another table layout with same name, but there is only one. My .xml file :

my xml

and my code is here layout6 = (TableLayout)findViewById(R.id.shdslResultsTableLayout); layout6.setVisibility(0);

always ends up with null pointer. Please help.

Answer 1

If findViewById() is returning a NPE, try some of these:

• Clean the project via Project -> Clean... -> check your project -> OK
• Ensure you have absolutely no spelling errors in the ID
• Make sure the contentView is displaying the correct layout where the TableLayout exists
• Make sure you setContentView before findViewById

I'm assuming the 3rd option I've listed is most likely your problem.

Re-cleaning the project may also help after each of these steps.

Answer 2

Please make sure you call the right layout in the setContentView method, and make sure you call setContentView BEFORE calling findViewById.

If you made that, then try to clean / rebuild.

Hope this will help you
