blocks|key|1049837|text|这可以使用Spannable字符串来实现。您将需要导入以下内容|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1049838|import+android.text.SpannableString;+
import+android.text.style.BackgroundColorSpan;+
import+android.text.style.StyleSpan;|code-block|syntax|javascript|1049839|然后，您可以使用类似以下内容来更改文本的背景：|1049840|TextView+text+=+(TextView)+findViewById(R.id.text_login);
text.setText("");
text.append("Add+all+your+funky+text+in+here");
Spannable+sText+=+(Spannable)+text.getText();
sText.setSpan(new+BackgroundColorSpan(Color.RED),+1,+4,+0);|1049841|这将用红色突出位置1-4处的字符。希望这能有所帮助！|1049842|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

This can be achieved using a Spannable String. You will need to import the following

<pre><code>import android.text.SpannableString; 
import android.text.style.BackgroundColorSpan; 
import android.text.style.StyleSpan;
</code></pre>

And then you can change the background of the text using something like the following:

<pre><code>TextView text = (TextView) findViewById(R.id.text_login);
text.setText("");
text.append("Add all your funky text in here");
Spannable sText = (Spannable) text.getText();
sText.setSpan(new BackgroundColorSpan(Color.RED), 1, 4, 0);
</code></pre>

Where this will highlight the charecters at pos 1 - 4 with a red color. Hope this helps!

blocks|key|1049876|text|另一种解决方案:改为使用WebView。Html很容易使用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1049877|WebView+webview+=+new+WebView(this);

String+summary+=+"<html><body>Sorry,+<span+style=\"background:+red;\">Madonna+gave+no+results</body></html>";

webview.loadData(summary,+"text/html",+"utf-8");|code-block|syntax|javascript|1049878|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|$]]

Alternative solution: Using a WebView instead. Html is easy to work with.

<pre><code>WebView webview = new WebView(this);

String summary = "&lt;html&gt;&lt;body&gt;Sorry, &lt;span style=\"background: red;\"&gt;Madonna&lt;/span&gt; gave no results&lt;/body&gt;&lt;/html&gt;";

webview.loadData(summary, "text/html", "utf-8");
</code></pre>

blocks|key|1049929|text|或者比手动处理Spannable简单得多，因为您没有说要突出显示背景，只希望突出显示文本：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1049930|String+styledText+=+"This+is+<font+color='red'>simple.";
textView.setText(Html.fromHtml(styledText),+TextView.BufferType.SPANNABLE);|code-block|syntax|javascript|1049931|entityMap^0|7|9|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

Or far simpler than dealing with <code>Spannable</code>s manually, since you didn't say that you want the background highlighted, just the text:

<pre><code>String styledText = "This is &lt;font color='red'&gt;simple&lt;/font&gt;.";
textView.setText(Html.fromHtml(styledText), TextView.BufferType.SPANNABLE);
</code></pre>

blocks|key|1049993|text|使用xml资源中的颜色值：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1049994|int+labelColor+=+getResources().getColor(R.color.label_color);
String+сolorString+=+String.format("%25X",+labelColor).substring(2);+//+alpha+value

Html.fromHtml(String.format("<font+color=\"#%25s\">text",+сolorString),+TextView.BufferType.SPANNABLE);+|code-block|syntax|javascript|1049995|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|$]]

Using color value from xml resource:

<pre><code>int labelColor = getResources().getColor(R.color.label_color);
String сolorString = String.format("%X", labelColor).substring(2); // !!strip alpha value!!

Html.fromHtml(String.format("&lt;font color=\"#%s\"&gt;text&lt;/font&gt;", сolorString), TextView.BufferType.SPANNABLE); 
</code></pre>

blocks|key|1264766|text|textview.setText(Html.fromHtml("<font+color='rgb'>"%2Btext+contain%2B""));|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|1264767|它会给出你在html编辑器中制作的颜色，只需设置文本视图并将其与文本视图值连接即可。Android不支持跨度颜色，在编辑器中将其更改为字体颜色，您就可以开始使用了。|unstyled|1264768|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

<pre><code>textview.setText(Html.fromHtml("&lt;font color='rgb'&gt;"+text contain+"&lt;/font&gt;"));
</code></pre>

It will give the color exactly what you have made in html editor , just set the textview and concat it with the textview value. Android does not support span color, change it to font color in editor and you are all set to go.

blocks|key|1264822|text|字体已弃用，请使用span而不是Html.fromHtml("<span+style=color:red>"%2Bcontent%2B"")|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1264823|entityMap^0|G|1L|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

To make part of your text underlined and colored

in your strings.xml

<pre><code>&lt;string name="text_with_colored_underline"&gt;put the text here and &amp;lt;u&gt;&amp;lt;font color="#your_hexa_color"&gt;the underlined colored part here&amp;lt;font&gt;&amp;lt;u&gt;&lt;/string&gt;
</code></pre>

then in the activity

<pre><code>yourTextView.setText(Html.fromHtml(getString(R.string.text_with_colored_underline)));
</code></pre>

and for clickable links:

<pre><code>&lt;string name="text_with_link"&gt;&lt;![CDATA[&lt;p&gt;text before link&lt;a href=\"http://www.google.com\"&gt;title of link&lt;/a&gt;.&lt;p&gt;]]&gt;&lt;/string&gt;
</code></pre>

and in your activity:

<pre><code>yourTextView.setText(Html.fromHtml(getString(R.string.text_with_link)));
yourTextView.setMovementMethod(LinkMovementMethod.getInstance());
</code></pre>

First Convert your string into HTML then convert it into spannable. do as suggest the following codes.
<pre><code> Spannable spannable = new SpannableString(Html.fromHtml(labelText));
 
spannable.setSpan(new ForegroundColorSpan(Color.parseColor(color)), spannable.toString().indexOf(&quot;•&quot;), spannable.toString().lastIndexOf(&quot;•&quot;) + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

I am developing an application in which there will be a search screen
where user can search for specific keywords and that keyword should be
highlighted. I have found Html.fromHtml method.

But I will like to know whether its the proper way of doing it or
not.

Please let me know your views on this.
