正如标题所说,我想知道是否有可能在单个textview元素中实现两个不同颜色的字符。
当前回答
自从API 24以来,你有FROM_HTML_OPTION_USE_CSS_COLORS,所以你可以在CSS中定义颜色,而不是一直重复使用font color=" 更清楚-当你有一些html,你想突出一些预定义的标签-你只需要在你的html顶部添加CSS片段
其他回答
试试这个:
mBox = new TextView(context);
mBox.setText(Html.fromHtml("<b>" + title + "</b>" + "<br />" +
"<small>" + description + "</small>" + "<br />" +
"<small>" + DateAdded + "</small>"));
使用SpannableStringBuilder
SpannableStringBuilder builder = new SpannableStringBuilder();
SpannableString str1= new SpannableString("Text1");
str1.setSpan(new ForegroundColorSpan(Color.RED), 0, str1.length(), 0);
builder.append(str1);
SpannableString str2= new SpannableString(appMode.toString());
str2.setSpan(new ForegroundColorSpan(Color.GREEN), 0, str2.length(), 0);
builder.append(str2);
TextView tv = (TextView) view.findViewById(android.R.id.text1);
tv.setText( builder, TextView.BufferType.SPANNABLE);
if (Build.VERSION.SDK_INT >= 24) {
Html.fromHtml(String, flag) // for 24 API and more
} else {
Html.fromHtml(String) // or for older API
}
用于24个API及以上(标志)
public static final int FROM_HTML_MODE_COMPACT = 63;
public static final int FROM_HTML_MODE_LEGACY = 0;
public static final int FROM_HTML_OPTION_USE_CSS_COLORS = 256;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1;
public static final int TO_HTML_PARAGRAPH_LINES_CONSECUTIVE = 0;
public static final int TO_HTML_PARAGRAPH_LINES_INDIVIDUAL = 1;
更多信息
你可以在没有HTML的情况下打印多种颜色的行:
TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");
word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");
wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);
尽可能使用SpannableBuilder类而不是HTML格式,因为它比HTML格式解析更快。 在Github上查看我自己的基准测试“SpannableBuilder vs HTML” 谢谢!
