在Circle内拆分大字符串

Question

我有机会查看Circle内的大文字。在大我意味着像图像2上的一些短语。

在视图上我将此方法中的字符串拆分为spase“”或字符串中心

IConditionManager

[第一张图片 - when it's not]

[第二张图片 - when it's work]

在onDraw方法中，我将String绘制成一行或两行

 public void setmText(CharSequence mText) {
    if(mText.length() < 11) {// it can be single line max Chars in line 11
        this.isOneTextLine= true;
        this.mText = mText;
    }else { // it can't be single line
        isOneTextLine = false;
        String str = mText.toString();
        if(str.contains(" ")) {
            int index = str.indexOf(" ");
            if(index < 11) {
                this.mText_second = str.substring(index + 1, str.length());
                this.mText = str.substring(0, index);
            }else {
                if(str.length() - (index+1) > 11 ) {
                    mText_second =  str.substring(str.length()/2, str.length());
                    this.mText = str.substring(0,str.length()/2) +"-";
                }else {
                    this.mText_second = str.substring(index + 1, str.length());
                    this.mText = str.substring(0, index);
                }
            }
        }else {
            mText_second =  str.substring(str.length()/2, str.length());
            this.mText = str.substring(0,str.length()/2) +"-";
        }
    }
}
