    或者像Kotlin一样:

    val tv = findViewById(R.id.textViewOne) as TextView
    tv.setTypeface(null, Typeface.BOLD_ITALIC)
    // OR
    tv.setTypeface(null, Typeface.BOLD or Typeface.ITALIC)
    // OR
    tv.setTypeface(null, Typeface.BOLD)
    // OR
    tv.setTypeface(null, Typeface.ITALIC)
    // AND
    tv.paintFlags = tv.paintFlags or Paint.UNDERLINE_TEXT_FLAG
    

    或者在Java中:

    TextView tv = (TextView)findViewById(R.id.textViewOne);
    tv.setTypeface(null, Typeface.BOLD_ITALIC);
    // OR
    tv.setTypeface(null, Typeface.BOLD|Typeface.ITALIC);
    // OR
    tv.setTypeface(null, Typeface.BOLD);
    // OR
    tv.setTypeface(null, Typeface.ITALIC);
    // AND
    tv.setPaintFlags(tv.getPaintFlags()|Paint.UNDERLINE_TEXT_FLAG);
    

    保持简单,一行:)

    我不知道下划线,但是对于粗体和斜体,有 "bolditalic" . 这里没有提到下划线:http://developer.android.com/reference/android/widget/TextView.html#attr_android:textStyle

    请注意,使用你需要提到的 bolditalic ,我引用该页面

    必须是以下常量值中的一个或多个(由“|”分隔) .

    所以你要用 bold|italic

    你可以查看这个问题的下划线:Can I underline text in an android layout?

    这应该使你的TextView boldunderlineditalic 同时 .

    strings.xml

    <resources>
        <string name="register"><u><b><i>Copyright</i></b></u></string>
    </resources>
    

    要将此String设置为TextView,请在 main.xml 中执行此操作

    <?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/textview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="@string/register" />
    

    或在 JAVA

    TextView textView = new TextView(this);
    textView.setText(R.string.register);
    

    有时,当您可能必须使用动态文本时,上述方法将没有用处 . 所以在这种情况下SpannableString开始行动了 .

    String tempString="Copyright";
    TextView text=(TextView)findViewById(R.id.text);
    SpannableString spanString = new SpannableString(tempString);
    spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
    spanString.setSpan(new StyleSpan(Typeface.BOLD), 0, spanString.length(), 0);
    spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0, spanString.length(), 0);
    text.setText(spanString);
    

    OUTPUT

    对于粗体和斜体,无论你做什么都是正确的下划线使用下面的代码

    HelloAndroid.java

    package com.example.helloandroid;
    
     import android.app.Activity;
     import android.os.Bundle;
     import android.text.SpannableString;
     import android.text.style.UnderlineSpan;
    import android.widget.TextView;
    
    public class HelloAndroid extends Activity {
    TextView textview;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        textview = (TextView)findViewById(R.id.textview);
        SpannableString content = new SpannableString(getText(R.string.hello));
        content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
        textview.setText(content);
    }
    }
    

    main.xml中

    <?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="@string/hello"
    android:textStyle="bold|italic"/>
    

    string.xml

    <?xml version="1.0" encoding="utf-8"?>
     <resources>
      <string name="hello">Hello World, HelloAndroid!</string>
      <string name="app_name">Hello, Android</string>
    </resources>

    这是添加下划线的简单方法,同时保持其他设置:

    textView.setPaintFlags(textView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

    Programmatialy:

    您可以使用setTypeface()方法以编程方式执行:

    下面是默认字体的代码

    textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
    textView.setTypeface(null, Typeface.BOLD);        // for Bold only
    textView.setTypeface(null, Typeface.ITALIC);      // for Italic
    textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic
    

    如果要设置自定义字体:

    textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
    textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
    textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
    textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic
    

    XML:

    您可以直接在XML文件中设置:

    android:textStyle="normal"
    android:textStyle="normal|bold"
    android:textStyle="normal|italic"
    android:textStyle="bold"
    android:textStyle="bold|italic"

    没有引号适合我:

    <item name="android:textStyle">bold|italic</item>

    If you are reading that text from a file or from the network.

    您可以通过向所提到的文本添加HTML标记来实现它

    This text is <i>italic</i> and <b>bold</b>
    and <u>underlined</u> <b><i><u>bolditalicunderlined</u></b></i>
    

    然后您可以使用HTML类将HTML字符串处理为可显示的样式文本 .

    // textString is the String after you retrieve it from the file
    textView.setText(Html.fromHtml(textString));

    style="?android:attr/listSeparatorTextViewStyle
    
    • 通过制作这种风格,你可以实现强调
