android textview settext show nullpointer exception
android, textview
Solution
Well, seems that `findViewById` returns `null`. This is probably the case, because `this` does not refer to the Activity or you're not assigning the View to the Activity in `onCreate` (you have to call `setContentView` in `onCreate`).
Problem
``` <TextView android:id="@+id/first_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@color/black" android:textColor="@color/light_grey" android:text="FirstName" ></TextView> TextView first_text_view; first_text_view = (TextView)this.findViewById(R.id.first_name); try { first_text_view.setText("Android"); }catch(Exception e) { } ``` i got the nullpointer exception. what is solution for this. please reply me
