You have to use the right <a href="http://xahlee.org/js/html_chars.html" rel="noreferrer">character encoding</a> to accomplish this effect. You could try with <code>&amp;#8226;</code>

 

<h3>Update</h3>

Just to clarify: use <code>setText("\u2022 Bullet");</code> to add the bullet programmatically. <code>0x2022 = 8226</code>

blocks|key|962878|text|这对我很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|962879|<string+name="text_with_bullet">Text+with+a+\u2022</string>|code-block|syntax|javascript|962880|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This worked for me:

<pre><code>&lt;string name="text_with_bullet"&gt;Text with a \u2022&lt;/string&gt;

Prolly a better solution out there somewhere, but this is what I did.

<pre><code>&lt;TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 &gt;
 &lt;TableRow&gt; 
 &lt;TextView
 android:layout_column="1"
 android:text="•"&gt;&lt;/TextView&gt;
 &lt;TextView
 android:layout_column="2"
 android:layout_width="wrap_content"
 android:text="First line"&gt;&lt;/TextView&gt;
 &lt;/TableRow&gt;
 &lt;TableRow&gt; 
 &lt;TextView
 android:layout_column="1"
 android:text="•"&gt;&lt;/TextView&gt;
 &lt;TextView
 android:layout_column="2"
 android:layout_width="wrap_content"
 android:text="Second line"&gt;&lt;/TextView&gt;
 &lt;/TableRow&gt;
 &lt;/TableLayout&gt;
</code></pre>

It works like you want, but a workaround really.

You may try <a href="https://developer.android.com/reference/android/text/style/BulletSpan.html" rel="noreferrer">BulletSpan</a> as described in Android docs.

<pre><code>SpannableString string = new SpannableString("Text with\nBullet point");
string.setSpan(new BulletSpan(40, color, 20), 10, 22, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

This is how i ended up doing it. 

<pre><code> &lt;LinearLayout
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:orientation="horizontal"&gt;

 &lt;View
 android:layout_width="20dp"
 android:layout_height="20dp"
 android:background="@drawable/circle"
 android:drawableStart="@drawable/ic_bullet_point" /&gt;

 &lt;TextView
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_marginLeft="10dp"
 android:text="Your text"
 android:textColor="#000000"
 android:textSize="14sp" /&gt;
 &lt;/LinearLayout&gt;
</code></pre>

and the code for drawbale/circle.xml is

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
 android:innerRadius="0dp"
 android:shape="ring"
 android:thickness="5dp"
 android:useLevel="false"&gt;

 &lt;solid android:color="@color/black1" /&gt;

&lt;/shape&gt;
</code></pre>

blocks|key|1177224|text|使用Unicode我们可以很容易地做到这一点，但如果想要更改项目符号的颜色，我尝试了彩色项目符号图像，并将其设置为可绘制左侧，它工作了|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1177225|<TextView+++++
++++android:text="Hello+bullet"
++++android:drawableLeft="@drawable/bulleticon"+>
</TextView>|code-block|syntax|javascript|1177226|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

With Unicode we can do it easily,but if want to change color of bullet, I tried with colored bullet image and set it as drawable left and it worked

<pre><code>&lt;TextView 
 android:text="Hello bullet"
 android:drawableLeft="@drawable/bulleticon" &gt;
&lt;/TextView&gt;
</code></pre>

blocks|key|963247|text|在任何文本视图中添加项目符号的另一种最佳方法是以下两个步骤：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|963248|首先，创建一个可绘制的|963249|<?xml+version="1.0"+encoding="utf-8"?>
<shape
++++xmlns:android="http://schemas.android.com/apk/res/android"
++++android:shape="oval">

++++
+++<solid+
+++++++android:color="#666666"/>+//set+color+of+bullet

++++
+++<size+
+++++++android:width="120dp"
++++++++android:height="120dp"/>
</shape>|code-block|syntax|javascript|963250|然后在textview中添加这个可绘制的，并使用以下属性设置它的踏板|963251|android:drawableStart="@drawable/bullet"
android:drawablePadding="10dp"|963252|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Another best way to add bullet in any text view is stated below two steps:
First, create a drawable
<pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
&lt;shape
 xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
 android:shape=&quot;oval&quot;&gt;

 &lt;!--set color of the bullet--&gt;
 &lt;solid 
 android:color=&quot;#666666&quot;/&gt; //set color of bullet

 &lt;!--set size of the bullet--&gt;
 &lt;size 
 android:width=&quot;120dp&quot;
 android:height=&quot;120dp&quot;/&gt;
&lt;/shape&gt;
</code></pre>
Then add this drawable in textview and set its pedding by using below properties
<pre><code>android:drawableStart=&quot;@drawable/bullet&quot;
android:drawablePadding=&quot;10dp&quot;
</code></pre>

blocks|key|1177346|text|由于安卓不支持<ol>,+<ul>+or+<li>+html元素，我不得不这样做|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1177347|<string+name="names"><![CDATA[<h2>List+of+Names:</h2>&#8226;name1<br+/>&#8226;name2<br+/>]]></string>|code-block|syntax|javascript|1177348|如果您想维护自定义空间，则使用</pre>+tag|1177349|entityMap^0|7|I|0|0|F|A|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

Since android doesnt support <code>&lt;ol&gt;, &lt;ul&gt; or &lt;li&gt;</code> html elements, I had to do it like this

<pre><code>&lt;string name="names"&gt;&lt;![CDATA[&lt;p&gt;&lt;h2&gt;List of Names:&lt;/h2&gt;&lt;/p&gt;&lt;p&gt;&amp;#8226;name1&lt;br /&gt;&amp;#8226;name2&lt;br /&gt;&lt;/p&gt;]]&gt;&lt;/string&gt;
</code></pre>

if you want to maintain custom space then use <code>&lt;/pre&gt; tag</code>
