1.两种手势：
手势检测与添加手势（用户手势）。
2.手势实现翻页的效果，如：阅读的上一页与下一页。。。
用控件ViewFlipper 与 GestureDetector 来实现.
3.代码提示：
package com.zking.gesture; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.GestureDetector; import android.view.MotionEvent; import android.widget.ImageView; import android.widget.ViewFlipper; public class MainActivity extends AppCompatActivity { private ViewFlipper main_viewflipper; private int images[]={R.drawable.s1,R.drawable.s5,R.drawable.s10,R.drawable.s11}; private GestureDetector gd; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); main_viewflipper = (ViewFlipper) findViewById(R.id.main_viewflipper); for (int i = 0; i < images.length; i++) { ImageView imageView=new ImageView(this); imageView.setImageResource(images[i]); main_viewflipper.addView(imageView); } gd = new GestureDetector(this, new GestureDetector.OnGestureListener() { @Override public boolean onDown(MotionEvent e) { Log.i("test","按下"); return false; } @Override public void onShowPress(MotionEvent e) { Log.i("test","按下，抬起之前"); } @Override public boolean onSingleTapUp(MotionEvent e) { Log.i("test","轻按"); return false; } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { Log.i("test","滚动"); return false; } @Override public void onLongPress(MotionEvent e) { Log.i("test","长按"); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { Log.i("test","拖动"); if(e2.getX()-e1.getX()>=200){ Log.i("test","向右滑"); main_viewflipper.showNext(); } if(e1.getX()-e2.getX()>=200){ Log.i("test","向左滑"); main_viewflipper.showPrevious(); } return false; } }); } @Override public boolean onTouchEvent(MotionEvent event) { return gd.onTouchEvent(event); } } 3.引用动画：
vf_main_image.setInAnimation(MainActivity.this,R.anim.left_in); vf_main_image.setOutAnimation(MainActivity.this,R.anim.right_out) ，用此代码。
