protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)

{

super.onMeasure(widthMeasureSpec, heightMeasureSpec);

int iconwidth = Math.min(getMeasuredWidth() - getPaddingLeft()

, getMeasuredHeight() - getPaddingTop()

- getPaddingBottom() - mTextBound.height());

int left=getMeasuredWidth()/2-iconwidth/2;

int top=getMeasuredHeight()/2-(mTextBound.height() + iconwidth)/2;

mIconRect=new Rect(left,top,left+iconwidth,top+iconwidth);

}

可是我的代码没有错啊
