推荐答案

您可以使用getSelectionStart（）和getSelectionEnd（）方法的光标位置。如果没有文本被高亮，无论getSelectionStart（）和getSelectionEnd（）返回光标的位置。因此，这样的事情应该做的伎俩：

You can get the Cursor position using the getSelectionStart() and getSelectionEnd() methods. If no text is highlighted, both getSelectionStart() and getSelectionEnd() return the position of the cursor. So something like this should do the trick:

myEditText.getSelectionStart();

或

myEditText.getSelectionEnd();

如果要选择光标之后，你可以用这一切的文字

然后：

Then if you want to select all the text after the cursor you could use this:

int cursorPosition = myEditText.getSelectionStart();
CharSequence enteredText = myEditText.getText().toString();
CharSequence cursorToEnd = enteredText.subSequence(cursorPosition, enteredText.length());
