当edittext文字太多时，并且包含话题时，长按键盘删除按钮删除太快导致崩溃问题解决

测试过程中发现在华为和vivo上级上出现这个问题，小米手机上没事。
出现问题的原因是，达到快速删除的时候，vivo手机上会一次删除两个字符，华为手机上就***

贴上解决代码，直接修改MentionInputConnection类sendKeyEvent就可以

` private int lastStart=-1;
private int lastend=-1;

@OverRide public boolean sendKeyEvent(KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN && event.getKeyCode() == KeyEvent.KEYCODE_DEL) {
if (null != mRangeManager) {
int selectionStart = mEditText.getSelectionStart();
int selectionEnd = mEditText.getSelectionEnd();
if (lastStart==selectionStart && lastend==selectionEnd){
return true;
}
Range closestRange =
mRangeManager.getRangeOfClosestMentionString(selectionStart, selectionEnd);

      if (closestRange == null) {
        mEditText.setSelected(false);
        if (selectionStart>0) {
          mEditText.getEditableText().delete(selectionStart - 1, selectionEnd);
          return true;
        }else {
          mEditText.setSelected(false);
          return super.sendKeyEvent(event);
        }
      }
      //if mention string has been selected or the cursor is at the beginning of mention string, just use default action(delete)
      if (mEditText.isSelected() || selectionStart == closestRange.getFrom()) {
        mEditText.setSelected(false);
       lastStart=selectionStart;
       lastend=selectionEnd;
        return super.sendKeyEvent(event);
      } else {
        //select the mention string
          if (isDeletable) {//可以删除,否则不进行处理
            mEditText.setSelected(true);
            mRangeManager.setLastSelectedRange(closestRange);
            setSelection(closestRange.getTo(), closestRange.getFrom());
        }
      }
      return true;
  }
}
return super.sendKeyEvent(event);

}

@zombiu @wzhangmoumou 请问 isDeletable 这个值是怎么判断的

我根据大佬的思路，做了一下拦截！

我试了一下，删除的时候还是在 setSelection(closestRange.getTo(), closestRange.getFrom()); 这个地方崩溃，请问您那边会这样吗

不会，这个功能已经上线几个月了，从来没出现过相关崩溃。

你那边改了能修复吗，要是可以的话，你就这样修改吧！

我这样是可以的，暂时没有发现其他问题。感谢您的回复！

报的是Fatal Exception: java.lang.IllegalArgumentException这个错误么，我仔细检查了下崩溃情况，有一例崩溃跟你发出来的类似！
