自定義TextView：

@SuppressLint("AppCompatCustomView")
public class MarqueeTextView extends TextView {

    public MarqueeTextView(Context context) {
        super(context);
    }

    public MarqueeTextView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public MarqueeTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean isFocused() {
        return true;
    }

}
