여러 개의 컬러 텍스트가있는 단일 TextView

여러 개의 컬러 텍스트가있는 단일 TextView

---

제목에서 알 수 있듯이 단일 textview 요소에서 두 가지 다른 색상의 문자를 얻을 수 있다는 것을 알고 싶습니다.

---

당신이를 포맷하는 경우 예, String함께 html의 font-color특성 다음 방법에 전달Html.fromHtml(your text here)

String text = "<font color=#cc0029>First Color</font> <font color=#ffcc00>Second Color</font>";
yourtextview.setText(Html.fromHtml(text));

---

다음과 같이 HTML없이 여러 색상으로 선을 인쇄 할 수 있습니다.

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);

---

에 Spannable효과를 적용 하는 데 사용할 수 있습니다 TextView.

다음은 TextView텍스트 의 첫 부분만을 색칠하는 예제입니다 (HTML 예제와 같이 문자열을 하드 코딩하는 대신 색상을 동적으로 설정할 수 있습니다!)

    mTextView.setText("Red text is here", BufferType.SPANNABLE);
    Spannable span = (Spannable) mTextView.getText();
    span.setSpan(new ForegroundColorSpan(0xFFFF0000), 0, "Red".length(),
             Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

이 예에서는 0xFFFF0000을 getResources().getColor(R.color.red)

---

나는 이렇게했다 :

문자열 과 색상 을 전달 하여 텍스트 색상 을 설정하십시오 .

private String getColoredSpanned(String text, String color) {
    String input = "<font color=" + color + ">" + text + "</font>";
    return input;
}

Set text on TextView / Button / EditText etc by calling below code:

TextView:

TextView txtView = (TextView)findViewById(R.id.txtView);

Get Colored String:

String name = getColoredSpanned("Hiren", "#800000");
String surName = getColoredSpanned("Patel","#000080");

Set Text on TextView of two strings with different colors:

txtView.setText(Html.fromHtml(name+" "+surName));

Done

Use 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);

Hey guys I have done this, try it

TextView textView=(TextView)findViewById(R.id.yourTextView);//init

//here I am appending two string into my textView with two diff colors.
//I have done from fragment so I used here getActivity(), 
//If you are trying it from Activity then pass className.this or this; 

textView.append(TextViewUtils.getColoredString(getString(R.string.preString),ContextCompat.getColor(getActivity(),R.color.firstColor)));
textView.append(TextViewUtils.getColoredString(getString(R.string.postString),ContextCompat.getColor(getActivity(),R.color.secondColor)));

Inside you TextViewUtils class add this method

 /***
 *
 * @param mString this will setup to your textView
 * @param colorId  text will fill with this color.
 * @return string with color, it will append to textView.
 */
public static Spannable getColoredString(String mString, int colorId) {
    Spannable spannable = new SpannableString(mString);
    spannable.setSpan(new ForegroundColorSpan(colorId), 0, spannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    Log.d(TAG,spannable.toString());
    return spannable;
}

I have write down some code for other question which is similar to this one, but that question got duplicated so i can't answer there so i am just putting my code here if someone looking for same requirement.

It's not fully working code, you need to make some minor changes to get it worked.

Here is the code:

I've used @Graeme idea of using spannable text.

String colorfulText = "colorfulText";       
    Spannable span = new SpannableString(colorfulText);             

    for ( int i = 0, len = colorfulText.length(); i < len; i++ ){
        span.setSpan(new ForegroundColorSpan(getRandomColor()), i, i+1,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);                     
    }   

    ((TextView)findViewById(R.id.txtSplashscreenCopywrite)).setText(span);

Random Color Method:

  private int getRandomColor(){
        Random rnd = new Random();
        return Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
    }

Use SpannableBuilder class instead of HTML formatting where it possible because it more faster then HTML format parsing. See my own benchmark "SpannableBuilder vs HTML" on Github Thanks!

Try this:

mBox = new TextView(context);
mBox.setText(Html.fromHtml("<b>" + title + "</b>" +  "<br />" + 
      "<small>" + description + "</small>" + "<br />" + 
      "<small>" + DateAdded + "</small>"));

if (Build.VERSION.SDK_INT >= 24) {
     Html.fromHtml(String, flag) // for 24 API  and more
 } else {
     Html.fromHtml(String) // or for older API 
 }

for 24 API and more (flag)

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;

It's better to use the string in the strings file, as such:

    <string name="some_text">
<![CDATA[
normal color <font color=\'#06a7eb\'>special color</font>]]>
    </string>

Usage:

textView.text=HtmlCompat.fromHtml(getString(R.string.some_text), HtmlCompat.FROM_HTML_MODE_LEGACY)

Awesome answers! I was able to use Spannable to build rainbow colored text (so this could be repeated for any array of colors). Here's my method, if it helps anyone:

private Spannable buildRainbowText(String pack_name) {
        int[] colors = new int[]{Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE};
        Spannable word = new SpannableString(pack_name);
        for(int i = 0; i < word.length(); i++) {
            word.setSpan(new ForegroundColorSpan(colors[i]), i, i+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        return word;
    }

And then I just setText(buildRainboxText(pack_name)); Note that all of the words I pass in are under 15 characters and this just repeats 5 colors 3 times - you'd want to adjust the colors/length of the array for your usage!

API 24부터 FROM_HTML_OPTION_USE_CSS_COLORS가 있으므로 font color="훨씬 더 명확하게 반복하지 않고 CSS에서 색상을 정의 할 수 있습니다-HTML이 있고 미리 정의 된 태그를 강조 표시하려는 경우 HTML 상단에 CSS 조각을 추가하면됩니다.
