我不知道如何使TextView上的特定文本变成粗体。
是这样的
txtResult.setText(id+" "+name);
我希望输出是这样的:
1111年尼尔
id和名称是我从数据库中检索值的变量,我想将id改为粗体,但只有id,所以名称不会受到影响,我不知道如何做到这一点。

当前回答
只需在标签中添加这个
dangerouslySetInnerHTML={{__html: "<p>Your html text here.<p>"}}
其他回答
val phone = "+45xxxxxx"
val phoneText = "<font color=#757B7F><b>${phone}</b></font>"
val wholeString = requireActivity().resources.getString(R.string.loginwith)+" "+phoneText
我用这个代码来加粗特定的单词…
Spanned string = Html.fromHtml("Normal string <b>BOLD STRING</b>");
textView.setText(string);
我创建了一个静态方法来设置文本粗体的TextView和EditText部分
public static void boldPartOfText(View mView, String contentData, int startIndex, int endIndex){
if(!contentData.isEmpty() && contentData.length() > endIndex) {
final SpannableStringBuilder sb = new SpannableStringBuilder(contentData);
final StyleSpan bss = new StyleSpan(Typeface.BOLD); // Span to make text bold
final StyleSpan iss = new StyleSpan(Typeface.NORMAL); //Span to make text normal
sb.setSpan(iss, 0, startIndex, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
sb.setSpan(bss, startIndex, endIndex, Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold
sb.setSpan(iss,endIndex, contentData.length()-1, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
if(mView instanceof TextView)
((TextView) mView).setText(sb);
else if(mView instanceof EditText)
((EditText) mView).setText(sb);
}
}
另一个更定制的代码
/*typeFaceStyle can be passed as
Typeface.NORMAL = 0;
Typeface.BOLD = 1;
Typeface.ITALIC = 2;
Typeface.BOLD_ITALIC = 3;*/
public static void boldPartOfText(View mView, String contentData, int startIndex, int endIndex,int typeFaceStyle){
if(!contentData.isEmpty() && contentData.length() > endIndex) {
final SpannableStringBuilder sb = new SpannableStringBuilder(contentData);
final StyleSpan bss = new StyleSpan(typeFaceStyle); // Span to make text bold
final StyleSpan iss = new StyleSpan(Typeface.NORMAL); //Span to make text italic
sb.setSpan(iss, 0, startIndex, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
sb.setSpan(bss, startIndex, endIndex, Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold
sb.setSpan(iss,endIndex,contentData.length()-1,Spanned.SPAN_INCLUSIVE_INCLUSIVE);
if(mView instanceof TextView)
((TextView) mView).setText(sb);
else if(mView instanceof EditText)
((EditText) mView).setText(sb);
}
}
当在list/recycler中搜索char时,使字符串的第一个char可扩展
拉维和阿杰
以前突出显示像这样,但我想像下面
ravi和ajay OR ravi和ajay
为此,我搜索单词长度,如果它等于1,我将主字符串分离成单词并计算单词开始位置,然后我搜索单词以char开头。
public static SpannableString colorString(int color, String text, String... wordsToColor) {
SpannableString coloredString = new SpannableString(text);
for (String word : wordsToColor) {
Log.e("tokentoken", "-wrd len-" + word.length());
if (word.length() !=1) {
int startColorIndex = text.toLowerCase().indexOf(word.toLowerCase());
int endColorIndex = startColorIndex + word.length();
try {
coloredString.setSpan(new ForegroundColorSpan(color), startColorIndex, endColorIndex,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
} catch (Exception e) {
e.getMessage();
}
} else {
int start = 0;
for (String token : text.split("[\u00A0 \n]")) {
if (token.length() > 0) {
start = text.indexOf(token, start);
// Log.e("tokentoken", "-token-" + token + " --start--" + start);
char x = token.toLowerCase().charAt(0);
char w = word.toLowerCase().charAt(0);
// Log.e("tokentoken", "-w-" + w + " --x--" + x);
if (x == w) {
// int startColorIndex = text.toLowerCase().indexOf(word.toLowerCase());
int endColorIndex = start + word.length();
try {
coloredString.setSpan(new ForegroundColorSpan(color), start, endColorIndex,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
} catch (Exception e) {
e.getMessage();
}
}
}
}
}
}
return coloredString;
}
字符串资源
<resources>
<string name="your_string_resource_name">This is normal text<![CDATA[<b> but this is bold </b>]]> and <![CDATA[<u> but this is underline text</u>]]></string>
</resources>
您的Java类
yourtextView.setText(getString(R.string.your_string_resource_name));
