package com.finddreams.slidingback.ui; 
 
 
import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.GestureDetector; 
import android.view.GestureDetector.OnGestureListener; 
import android.view.MotionEvent; 
 
public class GestureBackActivity extends Activity { 
 private GestureDetector myDectector; 
 private static final String TAG = "GestureBackActivity"; 
 boolean flingFinishEnabled = true; 
 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 
  super.onCreate(savedInstanceState); 
  initGestureDetector(); 
  AppManager.getAppManager().addActivity(this); 
 } 
 
 private void initGestureDetector() { 
  if (myDectector == null) { 
   myDectector = new GestureDetector(this, new MyGestureListener()); 
  } 
 
 } 
 
 @Override 
 public boolean dispatchTouchEvent(MotionEvent ev) { 
 
  if (flingFinishEnabled) { 
   return myDectector.onTouchEvent(ev) || super.dispatchTouchEvent(ev); 
  } 
  return super.dispatchTouchEvent(ev); 
 } 
 
  
 public class MyGestureListener implements onGestureListener { 
 
  @Override 
  public boolean onDown(MotionEvent e) { 
   // Toast.makeText(getApplicationContext(),"down",Toast.LENGTH_SHORT).show(); 
   return true; 
  } 
 
  @Override 
  public void onShowPress(MotionEvent e) { 
   // TODO Auto-generated method stub 
 
  } 
 
  @Override 
  public boolean onSingleTapUp(MotionEvent e) { 
   // Toast.makeText(getApplicationContext(),"onSingleTapUp",Toast.LENGTH_SHORT).show(); 
   return true; 
  } 
 
  @Override 
  public boolean onScroll(MotionEvent e1, MotionEvent e2, 
    float distanceX, float distanceY) { 
   // TODO Auto-generated method stub 
   return false; 
  } 
 
  @Override 
  public void onLongPress(MotionEvent e) { 
   // TODO Auto-generated method stub 
 
  } 
 
  @Override 
  public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
    float velocityY) { 
   if (e1.getX() - e2.getX() > 100 && Math.abs(velocityX) > 0) { 
    Log.d(TAG, "向左滑动"); 
   } else if (e2.getX() - e1.getX() > 100 && Math.abs(velocityX) > 0) { 
    Log.d(TAG, "向右滑动"); 
    AppManager.getAppManager().finishActivity(); 
   } 
   return false; 
  } 
 
 }
