Tough to do as ul/li/ol are not supported. Fortunately you can use this as syntactic sugar:

<pre><code>&amp;#8226; foo&lt;br/&gt;
&amp;#8226; bar&lt;br/&gt;
&amp;#8226; baz&lt;br/&gt;

<code>&amp;#8226;</code> is the html entity for a list bullet

An option I used was to set the bullet drawable using a style.

<pre><code>&lt;style name="Text.Bullet"&gt;
 &lt;item name="android:background"&gt;@drawable/bullet&lt;/item&gt;
 &lt;item name="android:paddingLeft"&gt;10dp&lt;/item&gt;
&lt;/style&gt;
</code></pre>

Usage:

<pre><code>&lt;TextView android:id="@+id/tx_hdr" 
android:text="Item 1" style="@style/Text.Bullet" /&gt;
</code></pre>

blocks|key|788654|text|使用简单的TextView和一个复合的可绘制。例如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|788655|<TextView+++++

Went completely overkill and made a custom text view.

Use it like this:

<pre><code>&lt;com.blundell.BulletTextView
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:text="--bullet 1 --bullet two --bullet three --bullet four" /&gt;
</code></pre>

and the code:

<pre><code>package com.blundell;

import android.content.Context;
import android.text.Html;
import android.util.AttributeSet;
import android.widget.TextView;

public class BulletTextView extends TextView {
 private static final String SPLITTER_CHAR = "--";
 private static final String NEWLINE_CHAR = "&lt;br/&gt;";
 private static final String HTML_BULLETPOINT = "&amp;#8226;";

 public BulletTextView(Context context, AttributeSet attrs) {
 this(context, attrs, android.R.attr.textViewStyle);
 }

 public BulletTextView(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 checkForBulletPointSplitter();
 }

 private void checkForBulletPointSplitter() {
 String text = (String) getText();
 if (text.contains(SPLITTER_CHAR)) {
 injectBulletPoints(text);
 }
 }

 private void injectBulletPoints(String text) {
 String newLinedText = addNewLinesBetweenBullets(text);
 String htmlBulletText = addBulletPoints(newLinedText);
 setText(Html.fromHtml(htmlBulletText));
 }

 private String addNewLinesBetweenBullets(String text) {
 String newLinedText = text.replace(SPLITTER_CHAR, NEWLINE_CHAR + SPLITTER_CHAR);
 newLinedText = newLinedText.replaceFirst(NEWLINE_CHAR, "");
 return newLinedText;
 }

 private String addBulletPoints(String newLinedText) {
 return newLinedText.replace(SPLITTER_CHAR, HTML_BULLETPOINT);
 }

}

blocks|key|788592|text|我发现这是最简单的方法，保留xml文件中的textView不变，并使用以下java代码。它对我来说工作得很好。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|788593|private+static+final+String+BULLET_SYMBOL+=+"&#8226";

I find this to be the easiest way, leave the textView as it is in the xml file and use the following java code. it worked perfectly fine for me.

<pre><code>private static final String BULLET_SYMBOL = "&amp;#8226";

@Override
protected void onCreate(Bundle savedInstanceState) 
{
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_tutorial);

 TextView tv = (TextView) findViewById(R.id.yourTextView);

 tv.setText("To perform this exercise you will need the following: "
 + System.getProperty("line.separator")//this takes you to the next Line
 + System.getProperty("line.separator")
 + Html.fromHtml(BULLET_SYMBOL + " Bed")
 + System.getProperty("line.separator")
 + Html.fromHtml(BULLET_SYMBOL + " Pillow"));
