// highlight text
public String colorfulltext(String text) {
String[] colors = new String[]{"#fdc113", "#fdc113", "#fdc113","#fdc113", "#fdc113" ,"#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc", "#fcfcfc","#fcfcfc","#fcfcfc","#fcfcfc","#fcfcfc"};
StringBuilder finals = new StringBuilder();
int size = colors.length;
int k = 0;
for (int item = 0; item < text.length(); item++) {
if (k >= size) {
k = 0;
}
finals.append("<font color='" + colors[k] + "'>" + text.charAt(item) + "</font>");
k++;
}
return finals.toString();
}

Why do you convert a String to html to apply fontcolor for a static text??
You have to follow the following steps:
Create entries in Strings.xml for each text. For instance, रिश्ते
has a different color and needs to be a separate entry in
strings.xml.
add this to a Util class:
public static void addColoredPart(SpannableStringBuilder ssb,
String word, int color,String... texts) {
for(String text : texts) {
if (word != null) {
int idx1 = text.indexOf(word);
if (idx1 == -1) {
return;
}
int idx2 = idx1 + word.length();
ssb.setSpan(new ForegroundColorSpan(color), idx1, idx2,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
}
}
apply style the following way:
String string1 = context.getString(R.string.String_id1)
String string2 = context.getString(R.string.String_id2)
SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder();
spannableStringBuilder.append(string2)
spannableStringBuilder.append(string2)
SpannableUtil.addColoredPart(
spannableStringBuilder,
spannableStringBuilder.toString(), color, string1, string2);

To show words in a text in bold with SetSpan and a loop

I have a text and an array (textviewArray) with 7 words. In my text exist these 7 words. I want to show these 7 words in this text in bold.
I have this code but the last word is bold, not all seven words:
textviewS.Text = "My Text ....";
strD = new SpannableStringBuilder("My Text ....");
bss = new StyleSpan(TypefaceStyle.Bold);
for (int i = 0; i < 7; i++)
{
if (textviewS.Text.IndexOf(textviewArray[i]) >= 0)
{
strD.SetSpan(bss, textviewS.Text.IndexOf(textviewArray[i]), (textviewS.Text.IndexOf(textviewArray[i]) + textviewArray[i].Length), 0);
}
}
textviewُ.SetText(strD, TextView.BufferType.Normal);

Try
String text = "text here";
String[] wordsToBold = {"word1", "word2", "word3", "word4", "word5", "word6", "word7"}
SpannableString spanString = FontUtility.getMultiFontText(context, "fonts/myfont.ttf", text, wordsToBold);
public static SpannableString getMultiFontText(Context context, int fontPathFromAssets, String text, String[] wordsToBold){
SpannableString spannableString = new SpannableString(text);
for(String word : wordsToBold) {
int startIndex = text.indexOf(word);
while(startIndex >= 0) {
int endIndex = startIndex+word.length();
spannableString.setSpan(new CustomTypefaceSpan(context, context.getString(fontPathFromAssets)), startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
startIndex = text.indexOf(word, endIndex + 1);
}
}
return spannableString;
}

how to set selected Text bold?

I want to set a selected text in an EditText bold.
It's already possible to find out what characters I selected and with getSelectionStart() and getSelectionEnd( ) I know where's the position.
But my problem is, that I want to set the selected Text bold with a Button and don't know how to set the font bold with a String (I only know how to set it with EditText).
So here is my sample code:
fettdruckButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int selectionStart = fullscreenEdittext.getSelectionStart();
int selectionEnd = fullscreenEdittext.getSelectionEnd();
int differenz = selectionEnd - selectionStart;
String selectedText = fullscreenEdittext.getText().toString().substring(selectionStart, selectionEnd);
Log.d("selectedText", "selectedText " + selectedText + "|" + selectionStart + "|" + selectionEnd);
//fullscreenEdittext.setTypeface(null, Typeface.BOLD);
}
});

Use SpannableStringBuilder.
SpannableStringBuilder stringBuilder = (SpannableStringBuilder) fullscreeneditText.getText();
stringBuilder.setSpan(new StyleSpan(Typeface.BOLD), selectionStart, selectionEnd, 0);
Please note that if you want to do this many times you should remove your original span first.

String completetext=fullscreenEdittext.getText().toString();
int selectionStart = fullscreenEdittext.getSelectionStart();
int selectionEnd = fullscreenEdittext.getSelectionEnd();
int differenz = selectionEnd - selectionStart;
String selectedText = fullscreenEdittext.getText().toString().substring(selectionStart, selectionEnd);
Log.d("selectedText", "selectedText " + selectedText + "|" + selectionStart + "|" + selectionEnd);
String part1=fullscreenEdittext.getText().toString().substring(0, selectionStart);
String part2=fullscreenEdittext.getText().toString().substring(selectionStart, selectionEnd);
String part3=fullscreenEdittext.getText().toString().substring(selectionEnd,completetext.length() );
fullscreenEdittext.setText(Html.fromHtml(part1+"<b>" + part2+ "</b>" +part3));

Use the property of Editext fullscreenEdittext.setText(Html.fromHtml(styledText));
Use html formatting tags <b>selectedText</b> to make the selected text bold.
Please have a look at below code snippet
int selectionStart = fullscreenEdittext.getSelectionStart();
int selectionEnd = fullscreenEdittext.getSelectionEnd();
String startingText = fullscreenEdittext.getText().toString()
.substring(0, selectionStart);
String selectedText = fullscreenEdittext.getText().toString()
.substring(selectionStart, selectionEnd);
String endingText = fullscreenEdittext.getText().toString()
.substring(selectionEnd);
fullscreenEdittext.setText(Html.fromHtml(startingText + "<b>"
+ selectedText + "</b>" + endingText));

Linkify any text Android

I want to add underline and colour to textview, but it is a simple text, not link, not phone number, just simple "Hello world", that I want to have with underline and that blue link-like colour.
It failed to do so:
view.setMovementMethod(LinkMovementMethod.getInstance());
Linkify.addLinks(view, Linkify.ALL);
Thank you! I just underlined the text as Const suggested and changed color of textview. But I guess xoxol_89's answer is correct in my case and should be accepted.

Do you try to use Spannable
For example
/**
* Method allocates filtering substring in all contacts yellow color,
* that satisfy the user's search
* #param inputText - DisplayName
* filtText - filtering Text
* #return String with allocating substring (Spannable)
*/
public static Spannable changeBackgroungFiltText(CharSequence inputText, String filtText, int color) {
Spannable str = null;
if(inputText != null)
{
String inputStr = inputText.toString();
String inputLowerCaseStr = inputStr.toLowerCase();
String filtLowerCaseStr = filtText.toLowerCase();
// Spannable str = new SpannableStringBuilder(inputStr);
str = new SpannableStringBuilder(inputStr);
if (filtText.length() != 0)
{
int indexStart = 0;
while (true)
{
int indexCur = inputLowerCaseStr.indexOf(filtLowerCaseStr, indexStart);
if (indexCur != -1) {
int start = indexCur;
int end = indexCur + filtText.length();
int flag = Spannable.SPAN_EXCLUSIVE_EXCLUSIVE;
str.setSpan(new ForegroundColorSpan(color),start, end, flag);
//str.setSpan(new BackgroundColorSpan(highlightColor), start, end, flag);
indexStart = indexCur + 1;
} else {
return str;
}
}
} else {
return str;
}
}
return str;
}

You can do that in 4 ways:
1.Automatically linkifies using android:autoLink=”all”
2.Link text by setMovementMethod
3.Link as html code using Html.fromHtml()
4.Link string by SpannableString
and you can find the examples here

You can use SpannableString like this:
final SpannableString text = new SpannableString("Hello World!");
final int startAt = 0;
final int endAt = text.length();
final int sampleColor = Color.parseColor("#3333ff");
text.setSpan(new UnderlineSpan(), startAt, endAt, 0);
text.setSpan(new ForegroundColorSpan(sampleColor), startAt, endAt, 0);
textView.setText(text);

Android: unable to change color of part of the text in textview

Hi iam trying to change part of the text in textview to some color but iam unble to achieve it
i tried fromHtml , spannable and different methoda but its still not working.
My tries are as below:
try1
Spannable wordtoSpan = Spannable.Factory.getInstance().newSpannable("text 6 Months(180 days) or 8,000 kilometers.");
wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 5, 15, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(wordtoSpan);
try2
String str = "#Second #Service:6 Months(180 days) or 8,000 kilometers.";
String[] str_array = str .split(" ");
boolean isExists = false;
for (int i = 0; i < str_array.length; i++) {
for (int j = 0; j < i; j++) {
if (str_array[j].equals(str_array[i])) {
isExists = true;
}
}
if (str_array[i].startsWith("#") && !isExists) {
str = str .replace(str_array[i],
"<font color='#8A0A0A'>" + str_array[i]
+ "</font>");
} else if (str_array[i].contains("#")) {
str = str .replaceAll(str_array[i],
"<font color='#000000'><b>" + str_array[i]
+ "</b></font>");
}
}
tv.setText(Html.fromHtml(str));
}
try3
myTextView.setText(Html.fromHtml(text + "<font color=white>" + CepVizyon.getPhoneCode() + "</font><br><br>"
+ getText(R.string.currentversion) + CepVizyon.getLicenseText()));
try4
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//method1
TextView tv = (TextView) findViewById(R.id.service);
tv.setText(Html.fromHtml("<font color=\"#FFFFFF\">" + "give your string here long long longlong" + "</font>" + "<font color=\"#47a842\"></font>"));
//method 2
//SpannableStringBuilder WordtoSpan = new SpannableStringBuilder("give your string here long long longlong");
//WordtoSpan.setSpan(new BackgroundColorSpan(Color.YELLOW),0,5,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
//tv.setText(WordtoSpan);
}
Any help is really appreciated.Thank you

Try like this. The below code is perfectly working for me, i have tested it.
TextView ttt = (TextView) findViewById(R.id.textView11);
String styledText = "This is <font color='red'>simple</font>.";
ttt.setText(Html.fromHtml(styledText), TextView.BufferType.SPANNABLE);
and here is output.

Try this it is running in my app perfectly.. May be it help you too
SpannableStringBuilder WordtoSpan = new SpannableStringBuilder(give your string here);
WordtoSpan.setSpan(new BackgroundColorSpan(Color.YELLOW),starting Index, and the index of text from which you want to highlight you text,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView.setText(WordtoSpan);
