SpannableString中的ClickableSpan和Textview点击事件冲突解决

背景描述：项目中有这样的需求：在展示评论内容的Textview中展示文字，其中包含3种类型数据：

1、普通文字：评论内容或者回复内容。因为这个Textview是展示评论或者回复的，点击后，要展示软键盘（popupwindow等忽略）

2、股票代码：该类型文字显示另一种颜色，并且点击后去到展示webView的activity展示股票网页

3、关联的人名：如：@123，显示不同于普通文字的颜色，点击后去到这个人的个人详情页

出现问题：在用SpannableString中的ClickableSpan的时候，会出现问题：点击了股票代码或者人名后，虽然会跳转，但是，会在跳转过程中出现软键盘，到底目标activity后，软键盘消失。这样展示不美观

解决方法：需要将点击的关键字的点击事件（即：ClickableSpan的点击事件和Textview的点击事件分开）

代码：

1、activity：

package com.chen.customviewdemo.activity;

import android.content.Context;
import android.view.View;
import android.view.inputmethod.InputMethodManager;

import com.chen.customviewdemo.R;
import com.chen.customviewdemo.bean.KeyBean;
import com.chen.customviewdemo.view.MyTextView_1;
import com.chen.customviewdemo.view.MyTextView_2;

import java.util.ArrayList;

/**
* 一个Textview中，有需要点击后专门处理的关键字，也有Textview自己的点击事件，
* 如：点击关键字跳转到其他activity中，点击非关键字后出现软键盘
* 有时候，会出现这样的情况：点击关键字后，跳转过程中，软键盘会弹出一瞬间。影响美观.
*/
public class MainActivity_34_Maching_ClickableSpan extends BaseActivity {

/**
* 说明：
* MyTextView_1：没有对关键字区域专门处理，点击后，非关键字区域还是会得到点击事件
* MyTextView_2：对关键字区域专门处理，点击后，非关键字区域没有获得点击事件
* 点击MyTextView_1中的关键字区域去跳转，没有出现软键盘闪现问题。但是项目中确实出现过。建议使用MyTextView_2
* 这里，为了说明情况，没有使用跳转。而是点击后弹出吐司。
* 在MyTextView_1中，点击关键字，弹出吐司，并且出现软键盘
* 在MyTextView_2中，点击关键字，仅弹出吐司，不出现软键盘
*/

MyTextView_1 my_textview_1;
MyTextView_2 my_textview_2;

@Override
void initview() {
setContentView(R.layout.activity_main_34);

my_textview_1 = (MyTextView_1) findViewById(R.id.my_textview_1);

2、布局：activity_main_34

</LinearLayout>

3、MyTextView_1：没有对关键字区域专门处理，点击后，非关键字区域还是会得到点击事件

4、MyTextView_2：对关键字区域专门处理，点击后，非关键字区域没有获得点击事件

5、KeyBean

* 这个时候，这个Url，就是隐式内容了。不必让用户看到，只是在触发后，隐含的做一定操作就行
