Set an onClickListner method to MapActivity

  Set an  onClickListner method to MapActivity

1) First do the setContentView, after that the Button is findable. The system could not find your Button now, so that's why it is a null. Your MapView map also would be a null in your code. 2) If you define an object within {} it is only available within that {} You probably going to need the Object "but" later, so make it a private variable of the class. 3) Classname should start with a capital. 4) Visit anddev.org or some site like that for coding problems, xda seems to be more focused on system/firmware issues, not application code. So, this should work: public class MainActivity extends MapActivity { final Button but; final MapView map; @Override public boolean isRouteDisplayed() { return false; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); but = (Button) findViewById(R.id.gpsButton); but.setOnClickListener(new View.OnClickListener() { public void onClick(View v){ } }); map = (MapView) findViewById(R.id.myMap); } }
