你可以用这个字体

创建一个类名TypefaceTextView并扩展TextView

私有静态Map mTypefaces;

public TypefaceTextView(final Context context) {
    this(context, null);
}

public TypefaceTextView(final Context context, final AttributeSet attrs) {
    this(context, attrs, 0);
}

public TypefaceTextView(final Context context, final AttributeSet attrs, final int defStyle) {
    super(context, attrs, defStyle);
    if (mTypefaces == null) {
        mTypefaces = new HashMap<String, Typeface>();
    }

    if (this.isInEditMode()) {
        return;
    }

    final TypedArray array = context.obtainStyledAttributes(attrs, styleable.TypefaceTextView);
    if (array != null) {
        final String typefaceAssetPath = array.getString(
                R.styleable.TypefaceTextView_customTypeface);

        if (typefaceAssetPath != null) {
            Typeface typeface = null;

            if (mTypefaces.containsKey(typefaceAssetPath)) {
                typeface = mTypefaces.get(typefaceAssetPath);
            } else {
                AssetManager assets = context.getAssets();
                typeface = Typeface.createFromAsset(assets, typefaceAssetPath);
                mTypefaces.put(typefaceAssetPath, typeface);
            }

            setTypeface(typeface);
        }
        array.recycle();
    }
}

将字体粘贴到资源文件夹中创建的字体文件夹中

<packagename.TypefaceTextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1.5"
        android:gravity="center"
        android:text="TRENDING TURFS"
        android:textColor="#000"
        android:textSize="20sp"
        app:customTypeface="fonts/pompiere.ttf" />**here pompiere.ttf is the font name**

将这些行放在xml的父布局中

 xmlns:app="http://schemas.android.com/apk/res/com.mediasters.wheresmyturf"
xmlns:custom="http://schemas.android.com/apk/res-auto"

设置属性

android:textStyle="bold"

4种方法使Android TextView粗体-完整的答案在这里。

Using android:textStyle attribute <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TEXTVIEW 1" android:textStyle="bold" /> Use bold|italic for bold and italic. using setTypeface() method textview2.setTypeface(null, Typeface.BOLD); textview2.setText("TEXTVIEW 2"); HtmlCompat.fromHtml() method, Html.fromHtml() was deprecated in API level 24. String html="This is <b>TEXTVIEW 3</b>"; textview3.setText(HtmlCompat.fromHtml(html,Typeface.BOLD));

通过XML:

 android:textStyle="bold"

通过Java:

//Let's say you have a textview 
textview.setTypeface(null, Typeface.BOLD);

要在layout.xml文件中这样做:

android:textStyle

例子:

android:textStyle="bold|italic"

程序上的方法是:

setTypeface(Typeface tf)

设置应显示文本的字体和样式。注意，并不是所有字体家族都有粗体和斜体变体，所以你可能需要使用setTypeface(Typeface, int)来获得你真正想要的外观。

你可以简单地做以下几点:

以XML格式设置属性

  android:textStyle="bold"

从程序上看，方法是:

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

Typeface boldTypeface = Typeface.defaultFromStyle(Typeface.BOLD);

Tv.setTypeface(boldTypeface);

希望这能帮到你，谢谢。
