用于進行dip和px轉換:

    public static int dip2px(Context context, float dpValue) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dpValue * scale + 0.5f);
    }

用于進行px和dip轉換

    public static int px2dip(Context context, float pxValue) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (pxValue / scale + 0.5f);
    }

檢測一段文字中是否含有某個詞匯

    public static boolean isHaveWord(String original,String haveWord){
        boolean flag=false;
        String replaceStr=original;
        if ((replaceStr.replaceAll(haveWord,"")).length()!=original.length()){
            flag=true;
        }
        return flag;
    }
