    TextViewBold textViewBold;
    TextViewMedium textViewMedium;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_example_one);

TextViewBold.java

public class TextViewBold extends TextView {

public  TextViewBold(Context context, AttributeSet attrs, int defStyle){
    super(context, attrs, defStyle);

    init(context);
}

public  TextViewBold(Context context,AttributeSet attrs){
    super(context,attrs);
    init(context);
}

public TextViewBold(Context context){
    super(context);
    init(context);
}


private void init(Context context) {
    if (!isInEditMode()) {
        Typeface tf = Typeface.createFromAsset(context.getAssets(),"Lato_Medium.ttf");
        setTypeface(tf);
    }
}

}

Answer 1

您的地址中缺少“ fonts /”，应该是这样的：

         setTypeface(Typeface.createFromAsset(getContext().getAssets(),"fonts/Lato_Medium.ttf"));

Answer 2

Pass context in your init(Context context)

And getAssets() like --> context.getAssets()

Typeface tf = Typeface.createFromAsset(context.getAssets(),"Lato_Medium.ttf");

isInEditMode() -->Ensure it will return true

Answer 3

我重新下载了字体样式并替换了fonts文件夹中的文件，它确实起作用。非常感谢您帮助解决了此问题
