正如标题所说,我想知道是否有可能在单个textview元素中实现两个不同颜色的字符。


当前回答

你可以在没有HTML的情况下打印多种颜色的行:

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);

如果你想在strings.xml中给出文本颜色和文本大小,那么检查下面的代码:

<string name="txt_my_string">
    <font fgcolor='#CFD8DC' > Text with given color </font> // Custom text color
    <font size="14" > Text with given size </font> // Custom Text size
    <font fgcolor='#3A55EA' size="14" > Text with given color and size </font> // Custom text color and size
</string>

希望你能容易理解:)

是的,如果你用html的font-color属性格式化字符串,然后把它传递给方法html . fromhtml(你的文本在这里)

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

你可以在没有HTML的情况下打印多种颜色的行:

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);

使用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);

很棒的答案!我能够使用Spannable构建彩虹色的文本(所以这可以重复为任何颜色的数组)。这是我的方法,如果它能帮助到任何人的话:

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;
    }

然后我只是setText(buildRainboxText(pack_name)); 注意,我传入的所有单词都在15个字符以下,这只是重复5种颜色3次-你需要根据你的使用调整数组的颜色/长度!
