```
  - analyzeMovement
```
protected boolean analyzeMovement()
```
  - isSloppyGesture
```
protected boolean isSloppyGesture()
```
    Check if we have a sloppy gesture. Sloppy gestures can happen if the edge of the user's hand is touching the screen, for example.
    Thanks to Almer Thie (code.almeros.com).
    
    返回:
    
    true if we detect sloppy gesture, false otherwise

  - getCurrentSpan
```
public float getCurrentSpan(int firstPointerIndex,
                            int secondPointerIndex)
```
    Returns the current distance between the two pointers forming the gesture in progress.
    Pointers are sorted by the time they were placed on the screen until lifted up. This means that index 0 will reflect the oldest added, still active pointer and index (getPointersCount() - 1) will reflect the latest added, still active pointer.
    The order of parameters is irrelevant.
    
    参数:
    
    firstPointerIndex - one of pointers indexes
    
    secondPointerIndex - one of pointers indexes
    
    返回:
    
    Distance between pointers in pixels.

    Pointers are sorted by the time they were placed on the screen until lifted up. This means that index 0 will reflect the oldest added, still active pointer and index (getPointersCount() - 1) will reflect the latest added, still active pointer.

    Returns current X distance between pointers in pixels.
    Pointers are sorted by the time they were placed on the screen until lifted up. This means that index 0 will reflect the oldest added, still active pointer and index (getPointersCount() - 1) will reflect the latest added, still active pointer.
