Scala的类的Java

Question

请与本Scala的类帮助我，我要实现它的Java这里，它是：

class StretchVideoView(context:Context, attr:AttributeSet) 
extends VideoView(context, attrib) { 
    def measure(measureSpec:Int):Int = { 
     val specMode = View.MeasureSpec.getMode(measureSpec) 
     View.MeasureSpec.getSize(measureSpec) 
    } 

    override def onMeasure(widthMeasureSpec:Int, heightMeasureSpec:Int) { 
     val (w,h) = (measure(widthMeasureSpec), measure(heightMeasureSpec)) 
     getHolder().setFixedSize(w,h) 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec) 
    } 
} 

我也试图在这里做我自己是我的Java代码：

class StretchVideoView extends VideoView { 

     public StretchVideoView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public int measure(int measureSpec) { 
     int specMode = View.MeasureSpec.getMode(measureSpec) 
     ??? View.MeasureSpec.getSize(measureSpec); // may be + here ??? 

     return specMode; // ??? 
    } 

     // and I'm not sure about this 
    @Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {  
     int w = measure(widthMeasureSpec); 
     int h = measure(heightMeasureSpec); 
     getHolder().setFixedSize(w,h); 
      super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    } 
} 

任何建议如何在Java上实现它？

我认为你需要为measure做这样的事情：

public int measure(int measureSpec) { 
    int specMode = View.MeasureSpec.getMode(measureSpec) 
    return View.MeasureSpec.getSize(measureSpec); 
}
