如何在隐藏链接时设置部分 TextView 可点击？

Question

我有一个 TextView 来显示电子邮件的收件人，原始字符串将类似于 "FirstName LastName <xx@yy.com>, FirstName LastName <xx@yy.com>, FirstName LastName <xx@yy.com>"。我想显示像"FirstName LastName, FirstName LastName, FirstName LastName" 这样的字符串，而FirstName LastName 是可点击的。我知道如何获取FirstName LastName，并且我知道如何使用URLSpan 使xx@yy.com 可点击，但它只会使xx@yy.com 可点击，我想要做的是只显示FirstName LastName 并使其可点击， 任何想法？

Answer 1

我通过扩展 ClickableSpan 并传入隐藏信息找到了解决方案，如下面的代码。

public class RecipientsSpan extends ClickableSpan {
    public String name;
    private String emailAddress;
    private int textColor;

    private RecipientsClickHandler recipientsClickHandler;

    public RecipientsSpan(String name, String emailAddress, int textColor) {
        super();
        this.name = name;
        this.emailAddress = emailAddress;
        this.textColor = textColor;
    }

    /**
     * Set the interface that will be used to handle the click event.
     * @param recipientsClickHandler interface to pass in.
     */
    public void setRecipientsClickHandler(@NonNull RecipientsClickHandler recipientsClickHandler) {
        this.recipientsClickHandler = recipientsClickHandler;
    }

    /**
     * Interface to handle click event for different spans inside the same TextView.
     */
    public interface RecipientsClickHandler {
        void onRecipientsClicked(@NonNull String name, @NonNull String emailAddress);
    }

    @Override
    public void onClick(View view) {
        if (recipientsClickHandler != null) {
            recipientsClickHandler.onRecipientsClicked(name, emailAddress);
        }
    }

    /**
     * Make text show the color specified and also avoid the default underline.
     * @param ds TextPaint that will be applied to the text.
     */
    @Override
    public void updateDrawState(@NonNull TextPaint ds) {
        ds.setColor(textColor);
        ds.setUnderlineText(false);
    }
}

对于每个 TextView，您可以在 Java 代码中设置一个 onClick 侦听器。 因此，您可以轻松地将 TextView 与 mailadress 链接
