android完美解决ClickableSpan中点击后ListView中item的长按冲突的问题

项目中碰到一个问题，情景是这样的：

有一个ListView，每个item中有一个TextView，textview实现了LongClick事件 实现复制文本的功能 ，这个TextView中又添加了ClickableSpan，实现了方法onClick。

我的需求是点击ClickableSpan，则响应ClickableSpan事件；长按ClickableSpan效果跟长按TextView应该一样，都响应TextView的LongClick事件。

研究了一下代码，解决方法如下：

package com.youxiake.controls;

import android.app.AlertDialog;
import android.content.ClipboardManager;
import android.content.Context;
import android.content.DialogInterface;
import android.text.Layout;
import android.text.Selection;
import android.text.Spannable;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewConfiguration;
import android.widget.TextView;
import android.widget.Toast;

import com.youxiake.util.MyLog;

public class TextViewFixTouchConsume extends TextView {
boolean dontConsumeNonUrlClicks = true;
   int linkHit;

   public OnClickListener onclick;


   public void setMyOnClickListener(OnClickListener onclick){
this.onclick=onclick;
   }

@Override
   public boolean hasFocusable() {
return false;
   }

public TextViewFixTouchConsume(Context context) {
super(context);
   }

public TextViewFixTouchConsume(Context context, AttributeSet attrs) {
super(context, attrs);
   }

public TextViewFixTouchConsume(Context context, AttributeSet attrs,
                           int defStyle) {
super(context, attrs, defStyle);
   }



// @Override
   // public void setOnLongClickListener(OnLongClickListener l) {
   //
   // ClipboardManager cmb =
   // (ClipboardManager)getContext().getSystemService(Context.CLIPBOARD_SERVICE);
   // cmb.setText(getText().toString().trim());
   // Toast.makeText(getContext(), "已复制", Toast.LENGTH_SHORT).show();
   //
   // };

   @Override
   public boolean onTouchEvent(MotionEvent event) {

//MyLog.debug_s("onTouchEvent:begin");

      boolean res = super.onTouchEvent(event);

      //MyLog.debug_s("onTouchEvent:"+res+",linkHit="+linkHit);

      return res;
   }
