我想通了.您需要继承 LinkMovementMethod 并添加对文本选择的支持.很遗憾它本身不支持它.我只是使用 源代码.我想这是 Android 开源的好处之一!
I figured it out. You need to subclass LinkMovementMethod and add support for text selection. It's really unfortunate that it doesn't support it natively. I just overrode the relevant methods using the equivalent ones from the source code for ArrowKeyMovementMethod
. I guess that's one benefit of Android being open source!
public class CustomMovementMethod extends LinkMovementMethod {
@Override
public boolean canSelectArbitrarily () {
return true;
}
@Override
public void initialize(TextView widget, Spannable text) {
Selection.setSelection(text, text.length());
}
@Override
public void onTakeFocus(TextView view, Spannable text, int dir) {
if ((dir & (View.FOCUS_FORWARD | View.FOCUS_DOWN)) != 0) {
if (view.getLayout() == null) {
// This shouldn't be null, but do something sensible if it is.
Selection.setSelection(text, text.length());
}
} else {
Selection.setSelection(text, text.length());
}
}
}
要使用它,只需直接实例化它,如下所示:
To use it, just instantiate it directly, like so:
textView.setMovementMethod(new CustomMovementMethod());
