怎么获取光标在那个EDITTEXT里面

Answer 1

遍历一下所有的edittext，然后EditText.isFocused()返回true说明是当前焦点。
这样就可以取到光标在哪个edittext里面了。

Answer 2

1.获取光标位置

[java] view plain copy
int index = editText.getSelectionStart();

2.在光标处插入字符

[java] view plain copy
int index = editText.getSelectionStart();
Editable editable = editText.getText();
editable.insert(index, "aaaa");
3.删除光标前字符

[java] view plain copy
int index = editText.getSelectionStart();
Editable editable = editText.getText();
editable.delete(index-1, index);
