pop_item_layout：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/tips_manager_bg"
    android:gravity="center"
    android:orientation="horizontal"
    android:padding="0dp" >

    <TextView
        android:id="@+id/pop_copy_tv"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:paddingBottom="6dp"
        android:text="复制"
        android:textColor="@android:color/white" />
 　<!--分割线-->
    <View
        android:layout_width="4dp"
        android:layout_height="fill_parent" />

    <TextView
        android:id="@+id/pop_delete_tv"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:paddingBottom="6dp"
        android:text="删除"
        android:textColor="@android:color/white" />

</LinearLayout>

TextManager：

package com.zihao.util;

import android.annotation.SuppressLint;
import android.content.ClipboardManager;
import android.content.Context;

/**
 * 文本操作工具类
 *
 * @author zihao
 *
 */
@SuppressLint("NewApi")
@SuppressWarnings("deprecation")
public class TextManager {

    /**
     * 复制文本
     *
     * @param context
     * @param message
     *            // 被复制的文本
     */
    public static void copyText(Context context, String message) {
        // 获取剪贴板管理服务
        ClipboardManager cmb = (ClipboardManager) context
                .getSystemService(Context.CLIPBOARD_SERVICE);
        // 将文本数据复制到剪贴板
        cmb.setText(message.trim());
    }

    /**
     * 粘贴文本
     *
     * @param context
     * @return
     */
    public static String pasteText(Context context) {
        // 得到剪贴板管理器
        ClipboardManager cmb = (ClipboardManager) context
                .getSystemService(Context.CLIPBOARD_SERVICE);
        return cmb.getText().toString().trim();
    }

}

MainActivity：在主函数应该有一个事件来触发 pasteText函数

package com.zihao.popdemo;

import java.util.ArrayList;
import java.util.List;

import com.zihao.adapter.MyAdapter;

import android.os.Bundle;
import android.widget.ListView;
import android.app.Activity;

/**
 * 主界面
 *
 * @author zihao
 *
 */
public class MainActivity extends Activity {

    private ListView mListView;// ListView
    private MyAdapter myAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initView();
    }

    /**
     * 初始化视图
     */
    private void initView() {
        mListView = (ListView) findViewById(R.id.my_list);
        myAdapter = new MyAdapter(this, getListData());
        mListView.setAdapter(myAdapter);
    }

    /**
     * 获取ListView数据
     *
     * @return
     */
    private List<String> getListData() {
        List<String> titleArray = new ArrayList<String>();
        for (int i = ; i < ; i++) {
            titleArray.add("这是第" + i + "个子项");
        }
        return titleArray;
    }

}
