I dont undestand, i have used this same code in main activity from the same app, and worked well. But when i use this in other activity, it throws me NullPointer.... Why is this?
private TextView drag_txtSeconds;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drag_layout);
drag_txtSeconds = (TextView)findViewById(R.id.TxtSeconds);
drag_txtSeconds.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v,MotionEvent event) {
return true;
}});
}
Hope you can help me :)

Make sure your file drag_layout
has a TextView
with the attribute:
android:id="@+id/TxtSeconds"
This is case sensitive, and may be due to the capital letters, try using all lowercase in the layout and in your code.
