Textview并不支持所有的html标签。如果更复杂的，可以直接使用webview组件。

Android TextView 支持的HTML标签

There is a lovely method on the android.text.Html  class, fromHtml() , that converts HTML into a Spannable  for use with a TextView .
However, the documentation does not stipulate what HTML tags are supported, which makes this method a bit hit-or-miss. More importantly, it means that you cannot rely on what it will support from release to release.
I have filed  an issue   requesting that Google formally document what it intends to support. In the interim, from a quick look at the source code, here’s what seems to be supported as of Android 2.1:
 
一、在xml文件中使用android:textStyle=”bold”
 
二、但是不能将中文设置成粗体，将中文设置成粗体的方法是： 
TextView tv =  ( TextView) findViewById( R. id . TextView01) ;  
TextPaint tp =  tv. getPaint ( ) ;  
tp. setFakeBoldText( true) ;


Selecting, Highlighting, or Styling Portions of Text

You can highlight or style the formatting of strings or substrings of text in a TextView object. There are two ways to do this:

If you use a string resource, you can add some simple styling, such as bold or italic using HTML notation. The currently supported tags are: B (bold), I (italic), U (underline), TT (monospace), BIG, SMALL, SUP (superscript), SUB (subscript), and STRIKE (strikethrough). So, for example, in res/values/strings.xml you could declare this:

    id="@+id/styled_welcome_message">We are so glad to see you.

To style text on the fly, or to add highlighting or more complex styling, you must use the Spannable object as described next.
To style text on the fly, you must make sure the TextView is using Spannable storage for the text (this will always be true if the TextView is an EditText), retrieve its text with getText(), and call setSpan(Object, int, int, int), passing in a new style class from the android.text.style package and the selection range.

The following code snippet demonstrates creating a string with a highlighted section, italic section, and bold section, and adding it to an EditText object.

// Get our EditText object.
EditText vw = (EditText)findViewById(R.id.text);

// Set the EditText's text.
vw.setText("Italic, highlighted, bold.");

// If this were just a TextView, we could do:
// vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE);
// to force it to use Spannable storage so styles can be attached.
// Or we could specify that in the XML.

// Get the EditText's internal text storage
Spannable str = vw.getText();

// Create our span sections, and assign a format to each.
str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
str.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
str.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 21, str.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

I sometimes have the case to arrange the p_w_picpath next to the characters.
We can do it by putting TextView and ImageView into Layout.
But today I introduce the other way using only TextView.
The following sample code is how to show the p_w_picpath next to text.
(show four p_w_picpath(left, top, right, bottom of text))


final TextView textView = (TextView)findViewById(R.id.diet_log_label);
final Drawable iconDrawable = getResources().getDrawable(R.drawable.icon);
textView.setCompoundDrawablesWithIntrinsicBounds(iconDrawable, iconDrawable, iconDrawable, iconDrawable);
// or
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, R.drawable.icon, R.drawable.icon, R.drawable.icon);


To show only left p_w_picpath, write "setCompoundDrawablesWithIntrinsicBounds(iconDrawable, null, null, null)"
