如何更改 TextView 部分的文本颜色？

Question

I have simple textView controler on my application.
On this textView i set the text "123456789" - the text color is black.

I want that the three last digit ( 789 ) will be shown with red text color.

Is there any simple way to do it without using two textView controls
(one will contain "123456" in black and second will contain "789" in red )

Answer 1

Try This:

Set TextView as a HTML using SpannableTextView

String text = "<font color='black'>123456</font><font color='red'>789</font>";
textView.setText(Html.fromHtml(text), TextView.BufferType.SPANNABLE);

Answer 2

您可以使用

myTextView.setText(Html.fromHtml(stringB + "<font color=red>" + stringA + "</font>);

You can use this method

public static final Spannable getColoredString(Context context, CharSequence text, int color) {
        Spannable spannable = new SpannableString(text);
        spannable.setSpan(new ForegroundColorSpan(color), 0, spannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        return spannable;
    }

then later you call is by using

textview.append(getColoredString(this, "Hi!", ContextCompact.getColor(this, R.color.red)));
textview.append(getColoredString(this, "User", ContextCompact.getColor(this, R.color.green)));

Answer 5

You can either use HTML banners in your java class: Example:

 textElement.setText(Html.fromHtml("123456 <fontcolor='#FF0000'>789</font>"));

Or use CData format in your XML file: Example:

<string name="numbers"><![CDATA[123456<fontcolor="#FF0000">789</font>]]></string>

I hope that helped you ;)
