Question

我有一系列的emogis：

 String rr [] = {":)",":D",":(",":'(",":P",":P","3:)","o.O",";)",":O","-_-",">:O",":*","<3","^_^","8-)","8|","(^^^)",
        ":|]",">:(",":v",":/",":3","☺","(y)",":poop:",":putnam:","<(\")","✌","☀","☁","☔","⚡","✨","⭐","✳", 

        "","","",
        "","","〽","","","","","","","" 
};

我需要替换此String

String mm = "Hello wold :D :P try emotions ";

我把它们作为图标的所有那些情感也是如此可以替代所有简单的字符串到图标并将它们附加到textView？

我想要什么

这是我的字符串

String mm = "Hello wold :D :P try emotions ";

有三种情绪

我有图标数组

我想用字符串替换字符串中的所有情感

      int icon[] = {R.drawable.a,R.drawable.b,R.drawable.c,R.drawable.d,R.drawable.e};
      String rr [] = {":)",":D",":(",":'(",":P",":P","3:)","o.O",";)",":O","-_-",};

所以在字符串String rr []中找到它们并用icon[]数组替换它们，以便在textView中显示它们，如果这样正确，我该如何找到和替换

Answer 1

您可以将SpannableString与TextView一起使用。这种类型的字符串允许您在TextView。

中使用内嵌图像

对于每个情感图标，您需要创建ImageSpan。此ImageSpan可以作为内嵌图像插入到字符串中。

ImageSpan is = new ImageSpan(context, R.drawable.arrow);

所以，你现在应该找到所有的情感角色并用ImageSpan s替换它们。

SpannableString text = new SpannableString("Your string here");

// Insert an ImageSpan into the string
text.setSpan(is, 5, 5 + 10, 0);

并将其应用于TextVeiw。

textView.setText(text);

android用图标
