You forgot the colon after •
你忘记了冒号 •
So change it to this:
所以把它改成这样：
String nodata="hi how are you<br/>•welcome to stackoverflow"
TextView nodata= ((TextView) findViewById(R.id.nodata));
nodata.setText(Html.fromHtml(nodatafound));

If you wanna do it in java (I means dynamically) use \nfor line break and Unicode character for bullet i.e. \u25CF.
如果你想在 Java 中（我的意思是动态）使用\n换行符和 Unicode 字符作为项目符号，即\u25CF.
This is How I'm using it
这是我如何使用它
textView.setText("Welcome Username\n\u25CF Some Instructions");
It looks as
Welcome Username
● Some Instructions
它看起来像
欢迎用户名
● 一些说明
Your case should be something like
你的情况应该是这样的
textView.setText("hi how are you\n\u25CF welcome to stackoverflow");
Here are some code
这是一些代码
? = \u2022
● = \u25CF
○ = \u25CB
? = \u25AA
■ = \u25A0
□ = \u25A1
? = \u25BA
? = \u2022
●
= \u25CF ○ = \u25CB
? = \u25AA
■ = \u25A0
□ = \u25A1
? = \u25BA

Try this out:
试试这个：
String s = "hello world"
+ System.getProperty ("line.separator")
+ "hello android"
+ System.getProperty ("line.separator");

Add in string.xml file
<string name="str">•item 1\n •item 2 \n • item 3</string>
在 string.xml 文件中添加
<string name="str">•item 1\n •item 2 \n • item 3</string>
