要实现滑屏等触发事件，视情况而定；

如果实现的触屏或者手势效果较多，则使用第一种方法，实现OnGestureListener 接口（参考OnGestureListener）；

如果只是实现较少的效果，则考虑使用SimpleOnGestureListener（参考SimpleOnGestureListenter）;主要分为以下三步：

第一种方法：

1、继承OnTouchListener , OnGestureListener ；

//继承OnTouchListener,OnGestureListener
public class MainActivity extends Activity implements OnTouchListener,OnGestureListener{

注：此处使用的OnGestureListener来自包 android.view.GestureDetector.OnGestureListener;而不是 android.gesture.GestureOverlayView.OnGestureListener;

2、初始化OnGestureListener ，即注册手势监听 ；获得当前接受操作的布局id ； 注册触屏监听；

//手势监听
mGestureDetector = new GestureDetector(MainActivity.this,(OnGestureListener) this);//(OnGestureListener) 可以省略
//获得当前接受操作的布局id
RelativeLayout mActivity = (RelativeLayout)findViewById(R.id.main_activity);
//触屏监听
mActivity.setOnTouchListener(this);
mActivity.setLongClickable(true);

3、重载onFling()和onTouch();

public boolean onTouch(View v, MotionEvent event) {return mGestureDetector.onTouchEvent(event);
}public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {//省略
}

第二种方法如下：

1、继承OnTouchListener  ；

//继承OnTouchListener
public class MainActivity extends Activity implements OnTouchListener{

2、初始化OnGestureListener ，即注册手势监听 ；获得当前接受操作的布局id ； 注册触屏监听；

//手势监听
mGestureDetector = new GestureDetector(MainActivity.this,new MySimpleOnGestureListener());//下边定义MySimpleOnGestureListener,//并使其继承SimpleOnGestureListener类
//获得当前接受操作的布局id
RelativeLayout mActivity = (RelativeLayout)findViewById(R.id.main_activity);
//触屏监听
mActivity.setOnTouchListener(this);
mActivity.setLongClickable(true);

3、定义SimpleOnGestureListener子类，并重载onTouch()和所需方法;

class MySimpleGestureListener extends SimpleOnGestureListener{@Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {//大于设定的最小滑动距离并且在水平/竖直方向速度绝对值大于设定的最小速度，则执行相应方法if(e1.getX()-e2.getX() > verticalMinistance && Math.abs(velocityX) > minVelocity){Toast.makeText(MainActivity.this, "turn left", Toast.LENGTH_SHORT).show();}else if(e2.getX() - e1.getX() > verticalMinistance && Math.abs(velocityX) > minVelocity){Toast.makeText(MainActivity.this, "turn right", Toast.LENGTH_SHORT).show();}else if(e1.getY()-e2.getY() > 20 && Math.abs(velocityY) > 10){Toast.makeText(MainActivity.this, "turn up", Toast.LENGTH_SHORT).show();}else if(e2.getY()-e1.getY() > 20 && Math.abs(velocityY) > 10){Toast.makeText(MainActivity.this, "turn down", Toast.LENGTH_SHORT).show();}return false;}@Overridepublic boolean onDown(MotionEvent e){Toast.makeText(MainActivity.this, "onDown", Toast.LENGTH_SHORT).show();return false;}}

具体代码如下：

（第一种方法）

import android.app.Activity;
import android.content.Intent;import android.os.Bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.*;public class MainActivity extends Activity implements OnTouchListener,OnGestureListener{private static final String tag = "mainActivity";private GestureDetector mGestureDetector;private int verticalMinistance = 20;          //水平最小识别距离private int minVelocity = 10;            //最小识别速度@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//手势监听mGestureDetector = new GestureDetector(MainActivity.this,(OnGestureListener) this);//(OnGestureListener) 可以省略//获得当前接受操作的布局idRelativeLayout mActivity = (RelativeLayout)findViewById(R.id.main_activity);//触屏监听mActivity.setOnTouchListener(this);mActivity.setLongClickable(true);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}@Overridepublic boolean onTouch(View v, MotionEvent event) {return mGestureDetector.onTouchEvent(event);}public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {//大于设定的最小滑动距离并且在水平/竖直方向速度绝对值大于设定的最小速度，则执行相应方法if(e1.getX()-e2.getX() > verticalMinistance && Math.abs(velocityX) > minVelocity){//在此处实现跳转//Intent intent  = new Intent(MainActivity.this,nextActivity.class);//startActivity(intent);Toast.makeText(MainActivity.this, "turn left", Toast.LENGTH_SHORT).show();}else if(e2.getX() - e1.getX() > verticalMinistance && Math.abs(velocityX) > minVelocity){Toast.makeText(MainActivity.this, "turn right", Toast.LENGTH_SHORT).show();}else if(e1.getY()-e2.getY() > 20 && Math.abs(velocityY) > 10){Toast.makeText(MainActivity.this, "turn up", Toast.LENGTH_SHORT).show();}else if(e2.getY()-e1.getY() > 20 && Math.abs(velocityY) > 10){Toast.makeText(MainActivity.this, "turn down", Toast.LENGTH_SHORT).show();}return false;}//只要有触发就会调用次方法@Overridepublic boolean onDown(MotionEvent e) {Toast.makeText(MainActivity.this, "onDown", Toast.LENGTH_SHORT).show();return false;}@Overridepublic void onLongPress(MotionEvent e) {Toast.makeText(MainActivity.this, "onLongPress", Toast.LENGTH_SHORT).show();}@Overridepublic boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {//       Toast.makeText(MainActivity.this, "onScroll", Toast.LENGTH_SHORT).show();return false;}@Overridepublic void onShowPress(MotionEvent e) {
//      Toast.makeText(MainActivity.this, "onShowPress", Toast.LENGTH_SHORT).show();}@Overridepublic boolean onSingleTapUp(MotionEvent e) {
//      Toast.makeText(MainActivity.this, "onsingleTapup", Toast.LENGTH_SHORT).show();return false;}
}
