声明：
1 float x_temp01 = 0.0f; 2 float y_temp01 = 0.0f; 3 float x_temp02 = 0.0f; 4 float y_temp02 = 0.0f;
重写Activity的onTouchEvent方法：
1 @Override 2 public boolean onTouchEvent(MotionEvent event) 3 { 4 //获得当前坐标 5 float x = event.getX(); 6 float y = event.getY(); 7 8 switch(event.getAction()) 9 { 10 case MotionEvent.ACTION_DOWN: 11 { 12 x_temp01 = x; 13 y_temp01 = y; 14 } 15 break; 16 case MotionEvent.ACTION_UP: 17 { 18 x_temp02 = x; 19 y_temp02 = y; 20 21 if(x_temp01!=0 && y_temp01!=0)// 22 { 23 // 比较x_temp01和x_temp02 24 // x_temp01>x_temp02 //向左 25 // x_temp01==x_temp02 //竖直方向或者没动 26 // x_temp01<x_temp02 //向右 27 28 if(x_temp01>x_temp02)//向左 29 { 30 //移动了x_temp01-x_temp02 31 } 32 33 if(x_temp01<x_temp02)//向右 34 { 35 //移动了x_temp02-x_temp01 36 } 37 } 38 } 39 break; 40 case MotionEvent.ACTION_MOVE: 41 { 42 43 } 44 break; 45 46 } 47 return super.onTouchEvent(event); 48 }
注经自己测试可行，简单好用；
自己更改判断是否滑动：
1 case MotionEvent.ACTION_DOWN: { 2 isMove = false; 3 downX=x; 4 downY=y; 5 break; 6 } 7 case MotionEvent.ACTION_UP: { 8 upX =x; 9 upY=y; 10 if ((upX-downX!=0)||(upY-downY!=0)) 11 isMove=true; 12 else 13 isMove=false; 14 break; 15 }
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))
