是否可以为TextView中的不同文本设置多个样式？

例如,我将文本设置如下:

tv.setText(line1 + "\n" + line2 + "\n" + word1 + "\t" + word2 + "\t" + word3);

是否可以为每个文本元素设置不同的样式？例如,line1粗体,word1斜体等.

开发人员指南的常见任务和Android中的操作方法包括选择,突出显示或设置部分文本样式:

// Get our EditText object.
EditText vw = (EditText)findViewById(R.id.text);

// Set the EditText's text.
vw.setText("Italic, highlighted, bold.");

// If this were just a TextView, we could do:
// vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE);
// to force it to use Spannable storage so styles can be attached.
// Or we could specify that in the XML.

我Html.fromHtml用来查看html TextView.

Spanned result = Html.fromHtml(mNews.getTitle());
...
...
mNewsTitle.setText(result);

但Html.fromHtml现在已经在Android N +中弃用了

我/我如何找到新的方法？

private void createStringEndingInRedColor(TextView tv, String word1, String word2) {
    Spannable word = new SpannableString(word1);
    tv.setText(word);

    Spannable wordTwo = new SpannableString(word2);

    wordTwo.setSpan(new ForegroundColorSpan(mContext.getResources().getColor(Color.RED)), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    tv.append(wordTwo);
}

我正在尝试为TextView tv编写一个单元测试(使用Robolectric)以确保wordTwo是Color.RED.但是,我只提到了TextView tv.怎么去做这样的任务？

I want a toast with multi-colors. Like this:

I looked at the different tutorials on changing the layout in the xml to create a custom Toast, but none of them explain adding different colors like this.

How can I do this?

ANSWER

================================

Using all your help, I have designed a simple Method() to make color toasts easier to call.

res/layout/toast_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toast_layout_root"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:paddingLeft="12dp"
    android:paddingRight="12dp"
    android:paddingBottom="6dp"
    android:paddingTop="6dp"
    android:background="#DAAA"
    >
    <TextView android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
</LinearLayout> …
