类定义

public  class  LyricView  extends  View {
    private  static  final  String TAG =  "LyricView" ;

    private  Paint paint;
    private  Rect rect;                 // 歌词显示区域
    private  List<Sentence> list =  null ;     // 歌词list
    private  String text =  "Lyric is loading..." ;            // 单行歌词
    private  long  currentTime =  0 ;         // 正在演唱的时间
    private  int  color =  0xFF0000FF ;    // 歌词颜色

    public  LyricView(Context context) {
        super (context);

        // 生成paint
        paint =  new  Paint();
        rect.left =  this .getLeft();
        rect.top =  this .getTop();
        rect.right =  this .getRight();
        rect.bottom =  this .getBottom();
    }

    public  LyricView(Context context, AttributeSet attrs) { // 构造方法；根据需要实现继承自View的方法
        super (context, attrs);

        // 生成paint
        paint =  new  Paint();
        rect.left =  10 ;
        rect.top =  50 ;
        rect.right =  10 ;
        rect.bottom =  50 ;

        //对于我们自定义的类中，我们需要使用一个名为obtainStyledAttributes的方法来获取我们的定义。
        //得到自定义控件的属性值。
    }


靠，原来是在构造函数中忘了创建rect对象 加上rect = new Rect();就ok了
