Nullpointerexception While Changing Textview Text In An Alertdialog

Background: I just want to create a customDialog with a specific layout and add the content. Its a DialogFragment Code: TextView text; @Override public void onCreate(Bundle save

Solution 1:

At first i thought its a Activity now i see its a DialogFragment.

I am guessing the view belongs to custom_dialog.xml

Viewview= inflater.inflate(R.layout.custom_dialog, null);
text = (TextView)view.findViewById(R.id.lorem); 
builder.setView(view);

So use the view object to initialize TextView.

text = (TextView)getView().findViewById(R.id.lorem); here getView() returns null.

You are calling setText on null leading to NullPointerException.
