推荐答案

假设你都获得了这是一个测试 字符串，你希望显示对话框中的子本并为子对话框乙测试。考虑以下方法：

Suppose you are given a "this is a test" String and you wish to show dialog A for the substring "this" and dialog B for the substring "test". Consider the following method:

private static void applySpan(SpannableString spannable, String target, ClickableSpan span) {
  final String spannableString = spannable.toString();
  final int start = spannableString.indexOf(target);
  final int end = start + target.length();
  spannable.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}

该方法采用中有一个 spannable ，第目标搜索发生和应用跨度它。显示 spannable 在的TextView ，从活动说，你可以做到以下几点：

The method takes a spannable, searches for the first target occurrence in it and applies the span to it. To show the spannable in a TextView, say from an Activity, you could do the following:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final SpannableString spannable = SpannableString.valueOf("this is a test");
    applySpan(spannable, "this", new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            // show dialog A
        }
    });
    applySpan(spannable, "test", new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            // show dialog B
        }
    });

    final TextView textView = new TextView(this);
    textView.setText(spannableString);
    textView.setMovementMethod(LinkMovementMethod.getInstance());

    setContentView(textView);
}

这只是一个粗糙的例子，但它希望证明的方式来解决问题。

This is just a crude example, but it hopefully demonstrates a way to solve your problem.
