  - setScale
```
void setScale(int percent)
```
    Sets the scaling of a WebView object. The default scaling is determined by this method as well as WebConfig#setViewPortFitScreen and WebConfig#setAutoFitOnLoad.
    
    参数:
    
    percent - Indicates the scaling percentage. Value 0 indicates the default scaling.

  - scaleUp
```
boolean scaleUp()
```
    Scales up a WebView object.
    
    返回:
    
    Returns true if the WebView object is scaled up; returns false otherwise.

  - scaleDown
```
boolean scaleDown()
```
    Scales down a WebView object.
    
    返回:
    
    Returns true if the WebView object is scaled down; returns false otherwise.

  - setScalable
```
void setScalable(boolean isScalable)
```
    Specifies whether a WebView object is scalable.
    
    参数:
    
    isScalable - Specifies whether the WebView object is scalable. Value true indicates that the WebView object is scalable, and value false indicates the opposite. The default value is true.

  - setGestureScalable
```
void setGestureScalable(boolean isScalable)
```
    Specifies whether a WebView object is scalable using gesture.
    
    参数:
    
    isScalable - Specifies whether the WebView object is scalable using gesture. Value true indicates that the WebView object is scalable using gesture, and false indicates the opposite. The default value is false.

  - setTextScale
```
void setTextScale(int percent)
```
    Sets the text scaling of a WebView object.
    
    参数:
    
    percent - Indicates the scaling percentage.
    
    从以下版本开始:

  - getTextScale
```
int getTextScale()
```
    Obtains the text scaling of a WebView object.
    
    返回:
    
    Returns the scaling percentage.
