La source comme suit:
public class test extends Activity implements OnTouchListener{
float downXValue;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set main.XML as the layout for this Activity
setContentView(R.layout.main);
// Add these two lines
LinearLayout layMain = (LinearLayout) findViewById(R.id.layout_main);
layMain.setOnTouchListener((OnTouchListener) this);
// Add a few countries to the spinner
Spinner spinnerCountries = (Spinner) findViewById(R.id.spinner_country);
ArrayAdapter countryArrayAdapter = new ArrayAdapter(this,android.R.layout.simple_spinner_dropdown_item,new String[] { "Canada", "USA" });
spinnerCountries.setAdapter(countryArrayAdapter);
}
public boolean onTouch(View arg0, MotionEvent arg1) {
// Get the action that was done on this touch event
switch (arg1.getAction())
{
case MotionEvent.ACTION_DOWN:
{
// store the X value when the user's finger was pressed down
downXValue = arg1.getX();
break;
}
case MotionEvent.ACTION_UP:
{
// Get the X value when the user released his/her finger
float currentX = arg1.getX();
// going backwards: pushing stuff to the right
if (downXValue < currentX)
{
// Get a reference to the ViewFlipper
ViewFlipper vf = (ViewFlipper) findViewById(R.id.details);
// Set the animation
vf.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_out));
// Flip!
vf.showPrevious();
}
// going forwards: pushing stuff to the left
if (downXValue > currentX)
{
// Get a reference to the ViewFlipper
ViewFlipper vf = (ViewFlipper) findViewById(R.id.details);
// Set the animation
vf.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));
// Flip!
vf.showNext();
}
break;
}
case MotionEvent.ACTION_MOVE:
ViewFlipper vf = (ViewFlipper) findViewById(R.id.details);
final View currentView = vf.getCurrentView();
currentView.layout((int)(arg1.getX() - downXValue),
currentView.getTop(), currentView.getRight(),
currentView.getBottom());
/*may be do something in thest*/
break;
}
// if you return false, these actions will not be recorded
return true;
}
}
