android android 判断是否滑动

声明：

     float x_temp01 = 0.0f;
     float y_temp01 = 0.0f;
     float x_temp02 = 0.0f;
     float y_temp02 = 0.0f; 

重写Activity的onTouchEvent方法：

  @Override
     public boolean onTouchEvent(MotionEvent event)
     {
         //获得当前坐标
             float x = event.getX();
             float y = event.getY();

             switch(event.getAction())
             {
                     case MotionEvent.ACTION_DOWN:
                     {
                         x_temp01 = x;
                         y_temp01 = y;
                     }
                     break;
                     case MotionEvent.ACTION_UP:
                     {
                         x_temp02 = x;
                         y_temp02 = y;

                         if(x_temp01!=0 && y_temp01!=0)//
                         {
                                 // 比较x_temp01和x_temp02
                                 // x_temp01>x_temp02         //向左
                                 // x_temp01==x_temp02         //竖直方向或者没动
                                 // x_temp01<x_temp02         //向右

                                 if(x_temp01>x_temp02)//向左
                                 {
                                         //移动了x_temp01-x_temp02
                                 }

                                 if(x_temp01<x_temp02)//向右
                                 {
                                         //移动了x_temp02-x_temp01
                                 }
                         }
                     }
                     break;
                     case MotionEvent.ACTION_MOVE:
                     {

                     }
                     break;

             }
             return super.onTouchEvent(event);
     }

注经自己测试可行，简单好用；

自己更改判断是否滑动：

         case MotionEvent.ACTION_DOWN: {
             isMove = false;
             downX=x;
             downY=y;
                         break;
                      }
         case MotionEvent.ACTION_UP: {
             upX =x;
             upY=y;
             if ((upX-downX!=0)||(upY-downY!=0))
                 isMove=true;
             else
                 isMove=false;
                         break;
                         }

注意：对于某些手机灵敏度太高，可考虑判断

if ((Math.abs(upX - downX) > 5) || (Math.abs(upY - downY) > 5))
