Android控件之--发送邮件时的，收件人列表，可以自动匹配，可以删除，可以添加的

先不管，截几个图：添加了2个Item ,后面那个是自动匹配联想。

根据每个Item的宽度，动态计算，一行到底放多少个Item.不够放，就换行(其实不是文本编辑器里的那种换行，是新建一个LinearLayout.嘿嘿)

每个Item的初始状态是没有那个叉叉的，当click一下它，它就变成黄色背景，并且那个白色的叉叉出现了。

click那个叉叉，就把它删除了，而且后面的那些要自动往前排(其实这里，目前的一种方式是很粗糙的方式，直接removeAll,然后再一个个的add进去)

废话少说，直接帖代码:如下------------》
1。先看主界面布局文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <com.test.demo.MyScrollView
        android:id="@+id/mScrollView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@color/color_white"/>

</LinearLayout>

单个Item的布局文件:
    <pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@color/color_light"
    android:gravity="center">

    <TextView
         android:id="@+id/itemTv"
         android:layout_width="wrap_content"
             android:layout_height="wrap_content">
    </TextView>

    <ImageView
        android:id="@+id/delete_iv"
        android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/email_delete">
    </ImageView>

</LinearLayout>

3.color.xml
[html]
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <drawable name="darkgray">#808080FF</drawable>
    <drawable name="white">#FFFFFFFF</drawable>
    <drawable name="black">#000000</drawable>
    <drawable name="silver">#00ffffff</drawable>
    <drawable name="text_yellow">#FFFF71</drawable>

    <color name="blue">#7F0000FF</color>
    <color name="transparent">#00000000</color>

     
    <color name="color_black">#000000</color>
    <color name="color_white">#FFFFFF</color>
    <color name="color_violet">#9900FF</color>
      <color name="color_orange">#fd810a</color>

    <color name="color_gray">#736F6E</color>
    <color name="color_dark">#161C27</color>
    <color name="color_light">#4D6288</color>
       <color name="color_middle">#F17EAB</color>


</resources>

2.再看Activity:

[java]
package com.test.demo;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class EditTextDemoActivity extends Activity {

    private MyScrollView mSrollView;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
            findViews();
    }

    private void findViews(){

            mSrollView = (MyScrollView)findViewById(R.id.mScrollView);

            mSrollView.setItemLayout(R.layout.email_item);

            String[] userNameList = new String[]{"Jacky","Jacky2","Jacky3",
                    "Jacky4","Jacky5","Jacky6","Jacky7","Jacky8"};&nb
