我的TextView具有ClickableStringSpan类型的跨度，定义如下：
public class ClickableStringSpan extends ClickableSpan {
private View.OnClickListener mListener;
int color;
public ClickableStringSpan(View.OnClickListener listener,int color) {
mListener = listener;
this.color = color;
}
@Override
public void onClick(View v) {
mListener.onClick(v);
}
@Override public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
ds.setColor(color);
}
}
我在文字上设置了可点击的跨度，如下所示：
spanStr.setSpan(new ClickableString(new linkedTextClickListener(), linkColor),
startIndex, endIndex,
SpannableString.SPAN_INCLUSIVE_EXCLUSIVE);
现在我想将这些字符串应用于EditTexts而不是TextViews。一切都很好只是可点击的字符串现在不再被点击了。我想知道如何将这种跨度的点击传递给指定的clicklistener？
更新：编辑文字的主要问题是我想让用户选择部分文字并分享，同时他/她可以点击ClickableSpans。

您需要将TextView的/ EditText的移动方法设置为LinkMovementMethod才能获取单击的链接。遗憾的是，这会禁用选择仅在将移动方法设置为ArrowKeyMovementMethod时才有效的文本的功能。 http://developer.android.com/reference/android/text/method/LinkMovementMethod.html http://developer.android.com/reference/android/text/method/ArrowKeyMovementMethod.html
为了解决这个问题，我创建了一个继承自ArrowKeyMovementMethod的自定义MovementMethod类，并添加了单击链接的功能。 ：
/**
* ArrowKeyMovementMethod does support selection of text but not the clicking of links.
* LinkMovementMethod does support clicking of links but not the selection of text.
* This class adds the link clicking to the ArrowKeyMovementMethod.
* We basically take the LinkMovementMethod onTouchEvent code and remove the line
* Selection.removeSelection(buffer);
* which deselects all text when no link was found.
*/
public class EnhancedMovementMethod extends ArrowKeyMovementMethod {
private static EnhancedMovementMethod sInstance;
public static MovementMethod getInstance() {
if (sInstance == null) {
sInstance = new EnhancedMovementMethod ();
}
return sInstance;
}
@Override
public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
int action = event.getAction();
if (action == MotionEvent.ACTION_UP ||
action == MotionEvent.ACTION_DOWN) {
int x = (int) event.getX();
int y = (int) event.getY();
x -= widget.getTotalPaddingLeft();
y -= widget.getTotalPaddingTop();
x += widget.getScrollX();
y += widget.getScrollY();
Layout layout = widget.getLayout();
int line = layout.getLineForVertical(y);
int off = layout.getOffsetForHorizontal(line, x);
ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {
link[0].onClick(widget);
}
else if (action == MotionEvent.ACTION_DOWN) {
Selection.setSelection(buffer, buffer.getSpanStart(link[0]), buffer.getSpanEnd(link[0]));
}
return true;
}
/*else {
Selection.removeSelection(buffer);
}*/
}
return super.onTouchEvent(widget, buffer, event);
}
}
您需要做的就是设置EditText的移动方法，然后您就可以了：
yourEditTExt.setMovementMethod(EnhancedMovementMethod.getInstance());
上面的代码仅适用于未格式化的文本，这意味着一旦您决定使用文本样式（粗体，斜体等）或不同的字体大小格式化文本，它将无法再找到单击的链接。我确实有处理格式化文本的代码，但由于这不是问题的一部分，我使示例代码尽可能短。

以下代码示例应该适合您，我也已经过测试，它会为您提供ClickableSpanString的点击事件
可能您忘记添加setMovementMethod
EditText spanEditText = (EditText)rootView.findViewById(R.id.edtEmailId);
// this is the text we'll be operating on
SpannableStringBuilder text = new SpannableStringBuilder("World Super Power God LOVE");
// make "World" (characters 0 to 5) red
text.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);
// make "Super" (characters 6 to 11) one and a half time bigger than the textbox
text.setSpan(new RelativeSizeSpan(1.5f), 6, 11, 0);
// make "Power" (characters 12 to 17) display a toast message when touched
final Context context = getActivity().getApplicationContext();
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View view) {
Toast.makeText(context, "Power", Toast.LENGTH_LONG).show();
}
};
text.setSpan(clickableSpan, 12, 17, 0);
// make "God" (characters 18 to 21) struck through
text.setSpan(new StrikethroughSpan(), 18, 21, 0);
// make "LOVE" (characters 22 to 26) twice as big, green and a link to this site.
// it's important to set the color after the URLSpan or the standard
// link color will override it.
text.setSpan(new RelativeSizeSpan(2f), 22, 26, 0);
text.setSpan(new ForegroundColorSpan(Color.GREEN), 22, 26, 0);
// make our ClickableSpans and URLSpans work
spanEditText.setMovementMethod(LinkMovementMethod.getInstance());
// shove our styled text into the TextView
spanEditText.setText(text, BufferType.EDITABLE);

以上答案很有帮助。希望以下内容对您也有帮助：
android:linksClickable="true"
android:autoLink="web"
val message: String = String.format(
getString(R.string.message_content),
firstNameEditText.text,
lastNameEditText.text,
dateTextView.text,
timeTextView.text
)
val gMapURL = getString(R.string.google_map_location)
// Setup my Spannable with clickable URLs
val spannable: Spannable = SpannableString(gMapURL)
Linkify.addLinks(spannable, Linkify.WEB_URLS)
// Append a zero-width space to the Spannable
val gText = TextUtils.concat(spannable, "\u200B")
val finalText = TextUtils.concat(message, gText)
messageContentEditText.setText(finalText)
