blocks|key|2965841|text|如果您所说的“自定义字体”指的是您作为资产提供的字体，则以下代码应该可以工作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2965842|Typeface+plain+=+Typeface.createFromAsset(assetManager,+pathToFont);+
Typeface+bold+=+Typeface.create(plain,+Typeface.DEFAULT_BOLD)

If by "custom font" you mean a font that you are supplying as an asset, the following code should work:

<pre><code>Typeface plain = Typeface.createFromAsset(assetManager, pathToFont); 
Typeface bold = Typeface.create(plain, Typeface.DEFAULT_BOLD)
Paint paint = new Paint();
paint.setTypeface(bold);
canvas.drawText("Sample text in bold",0,0,paint);
</code></pre>

blocks|key|2965862|text|如果你已经有一个正在使用的字体，并且想要使用它的粗体版本，你可以这样做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2965863|currentPainter+=+new+Paint(Paint.ANTI_ALIAS_FLAG);

If you already have a font in use and want to use a bold version of that you can do this.

<pre><code>currentPainter = new Paint(Paint.ANTI_ALIAS_FLAG);
currentPainter.setColor(Color.WHITE);
currentPainter.setTextSize(Utils.sp2px(getResources(), 14)); // set font size
Typeface currentTypeFace = currentPainter.getTypeface();
Typeface bold = Typeface.create(currentTypeFace, Typeface.BOLD);
currentPainter.setTypeface(bold);
</code></pre>

I used the answer above, but this modification was necessary for me - so just thought I'd mention it

blocks|key|271806|text|对paint类使用此命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|271807|+Paint+paint+=+new+Paint();

Use this for paint class:

<pre><code> Paint paint = new Paint();

If you want to use a font from resources (Kotlin):

<pre><code>val textPaint = TextPaint()
textPaint.typeface = resources.getFont(R.font.font_name)

This might not be related to the question, but this is what I was looking for - maybe somebody would need it too.

If you are using Android's new Fonts in XML for your fonts, then to get the typeface used for paint you can use: 

<pre><code>val customTypeface = ResourcesCompat.getFont(context, R.font.myfont)
</code></pre>

or if your min Android API >= 26

<pre><code>val customTypeface = resources.getFont(R.font.myfont)
</code></pre>

Then to apply it to your paint object:

<pre><code>mTextPaint.typeface = customTypeface
</code></pre>

I want to draw a text to a paint. How to draw it with a custom font (ex Helvetica ) and bold also? I would preffer to use a system font and not create it from assets. Thanks.

我想画一幅画上的文字。如何使用自定义字体(ex Helvetica )和粗体绘制它？我更喜欢使用系统字体，而不是从资源创建它。谢谢。
