In my application I want show some text into TextView, and I get this text from server.
I should use just one textView in XML layout, and I should set color for this Texts.
My XML : 

<TextView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="@dimen/size3"
    android:layout_marginTop="@dimen/padding8"
    android:layout_toRightOf="@+id/rowExplore_imageCard"
    android:fontFamily="sans-serif"
    android:gravity="left|center_vertical"
    android:text="Adam"
    android:textColor="@color/colorPrimary"
    android:textSize="@dimen/font14" />

JSON : 

  "name": "Adam Sandel",
  "info": "liked",
  "movieName": "SpiderMan",

Java code : 

rowExplore_userName.setText(response.getName() + response.getInfo() + response.getMovieName() );

I would have another approach just create one method

 public String getColoredString(String pname) {
    Random rnd = new Random();
    int color = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
    Spannable wordToSpan = new SpannableString(pname);
    wordToSpan.setSpan(new ForegroundColorSpan(color), 0, pname.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    return wordToSpan.toString();
}

and use above method 

rowExplore_userName.setText(getColoredString(response.getName())+getColoredString(response.getInfo())+getColoredString(response.getMovieName()));

this should work.

You can use SpannableString if you want to avoid using HTML tags

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

Spannable wordToSpan = new SpannableString("Your text is here");        
wordToSpan.setSpan(new ForegroundColorSpan(Color.BLUE), indexStart, indexEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(wordToSpan);

and it is more flexible since you can make more changes to your text (text size, bold/italic, etc)

I used this code:

String colorStr="#FFFFFF" //put your hex color 
int color =  Color.parseColor(colorStr);
editText.setTextColor(color);

A better approach to this is to create a string resource with appropriate HTML tags:

<string name="html_string" formatted="false">
    <![CDATA[
       <font color="yellow">%s</font> %s <font color="yellow">%s</font>
    ]]>
</string>

And then get that string with resources:

String htmlString = getString(R.strings.html_string, response.getName(), response.getInfo(), response.getMovieName());
rowExplore_userName.setText(htmlString);

You can use HTML

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