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;

// 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;}
