Android 单击listview弹出popupwindow弹出框

，里面还附带listview右滑删除按钮详情查看：Android 使用NineOldAndroids实现仿微信listview左滑出现删除itembutton。项目就是这样慢慢变得复杂，是往里面逐渐加功能，效果，代码。

一、看实现的效果

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

二、项目结构图

三、部分源代码

1、MyApplication继承了Application

package com.main.listviewsideslip;

import java.io.File;

import com.nostra13.universalimageloader.cache.disc.impl.UnlimitedDiskCache;

import com.nostra13.universalimageloader.cache.disc.naming.HashCodeFileNameGenerator;

import com.nostra13.universalimageloader.cache.disc.naming.Md5FileNameGenerator;

import com.nostra13.universalimageloader.cache.memory.impl.LruMemoryCache;

import com.nostra13.universalimageloader.cache.memory.impl.UsingFreqLimitedMemoryCache;

import com.nostra13.universalimageloader.core.DisplayImageOptions;

import com.nostra13.universalimageloader.core.ImageLoader;

import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;

import com.nostra13.universalimageloader.core.assist.QueueProcessingType;

import com.nostra13.universalimageloader.core.decode.BaseImageDecoder;

import com.nostra13.universalimageloader.core.download.BaseImageDownloader;

import com.nostra13.universalimageloader.utils.StorageUtils;

import android.app.Application;

import android.content.Context;

public class MyApplication extends Application{

	public void onCreate() {

		super.onCreate();

		initImageLoader(getApplicationContext());

	}

	public static void initImageLoader(Context context) {

		//缓存文件的文件夹

		File cacheDir = StorageUtils.getOwnCacheDirectory(context, "imageloader/Cache");

		ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)

				.memoryCacheExtraOptions(480, 800) // max width, max height，即保存的每一个缓存文件的最大长宽

				.threadPoolSize(3) //线程池内载入的数量

				.threadPriority(Thread.NORM_PRIORITY - 2)

				.denyCacheImageMultipleSizesInMemory()

				.diskCacheFileNameGenerator(new Md5FileNameGenerator()) //将保存的时候的URI名称用MD5 加密

				.memoryCache(new UsingFreqLimitedMemoryCache(2 * 1024 * 1024)) // You can pass your own memory cache implementation/你能够通过自己的内存缓存实现

				.memoryCacheSize(2 * 1024 * 1024) // 内存缓存的最大值

				.diskCacheSize(50 * 1024 * 1024)  // 50 Mb sd卡(本地)缓存的最大值

				.tasksProcessingOrder(QueueProcessingType.LIFO)

				// 由原先的discCache -> diskCache

				.diskCache(new UnlimitedDiskCache(cacheDir))//自己定义缓存路径

				.imageDownloader(new BaseImageDownloader(context, 5 * 1000, 30 * 1000)) // connectTimeout (5 s), readTimeout (30 s)超时时间

				.writeDebugLogs() // Remove for release app

				.build();

		//全局初始化此配置

		ImageLoader.getInstance().init(config);

	}

}

2、适配器RecentAdapter里面相同设置着网络载入配置。

package com.listview.adapter;

import java.util.LinkedList;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.Button;

import android.widget.ImageView;

import android.widget.TextView;

import com.main.entity.RecentItem;

import com.main.listviewsideslip.Constants;

import com.main.listviewsideslip.R;

import com.nostra13.universalimageloader.core.DisplayImageOptions;

import com.nostra13.universalimageloader.core.ImageLoader;

import com.nostra13.universalimageloader.core.display.RoundedBitmapDisplayer;

import com.view.listview.SwipeListView;

public class RecentAdapter extends BaseAdapter {

	private LayoutInflater mInflater;

	private LinkedList<RecentItem> mData;

	private SwipeListView mListView;

	private Context mContext;

	private DisplayImageOptions mOptions; // 设置图片显示相关參数

	public static String[] mImageUrls; // 图片路径

	private ImageLoader mImageLoader;   //网络图片载入类

	public RecentAdapter(Context context, LinkedList<RecentItem> data,

			SwipeListView listview) {

		mContext = context;

		this.mInflater = LayoutInflater.from(mContext);

		mData = data;

		this.mListView = listview;

		mImageLoader = ImageLoader.getInstance();

		initImageView();

	}

	public void remove(int position) {

		if (position < mData.size()) {

			mData.remove(position);

			notifyDataSetChanged();

		}

	}

	public void remove(RecentItem item) {

		if (mData.contains(item)) {

			mData.remove(item);

			notifyDataSetChanged();

		}

	}

	public void addFirst(RecentItem item) {

		if (mData.contains(item)) {

			mData.remove(item);

		}

		mData.addFirst(item);

		notifyDataSetChanged();

	}

	@Override

	public int getCount() {

		return mData.size();

	}

	@Override

	public Object getItem(int position) {

		return mData.get(position);

	}

	@Override

	public long getItemId(int position) {

		return position;

	}

	@Override

	public View getView(final int position, View convertView, ViewGroup parent) {

		final RecentItem item = mData.get(position);

		ViewHolder vHolder = null;

		if (convertView == null) {

			convertView = mInflater.inflate(R.layout.recent_listview_item, null);

			vHolder = new ViewHolder();

			vHolder.nameTV = (TextView) convertView.findViewById(R.id.recent_list_item_name);

			vHolder.numTV = (TextView) convertView.findViewById(R.id.unreadmsg);

			vHolder.headIV = (ImageView) convertView.findViewById(R.id.icon);

			vHolder.deleteBtn = (Button) convertView.findViewById(R.id.recent_del_btn);

			convertView.setTag(vHolder);

		}else {

			vHolder  = (ViewHolder) convertView.getTag();

		}

		vHolder.nameTV.setText(item.getName());

		/**

		 * imageUrl 图片的Url地址 imageView 承载图片的ImageView控件 options

		 * DisplayImageOptions配置文件

		 */

		mImageLoader.displayImage(mImageUrls[position],

				vHolder.headIV, mOptions);

		int num = item.getNewNum();

		if (num > 0) {

			vHolder.numTV.setVisibility(View.VISIBLE);

			vHolder.numTV.setText(num + "");

		} else {

			vHolder.numTV.setVisibility(View.GONE);

		}

		vHolder.deleteBtn.setOnClickListener(new OnClickListener() {

			@Override

			public void onClick(View v) {

				mData.remove(position);

				notifyDataSetChanged();

				if (mListView != null)

					mListView.closeOpenedItems();

			}

		});

		return convertView;

	}

	class ViewHolder{

		public TextView nameTV;

		public TextView numTV;

		public ImageView headIV;

		public Button deleteBtn;

	}

3、怎么调用，事实上都在上面那个适配器里面。也顺便看看MainActivity

package com.main.listviewsideslip;

import java.util.Collections;

import java.util.LinkedList;

import com.listview.adapter.RecentAdapter;

import com.main.entity.RecentItem;

import com.view.listview.BaseSwipeListViewListener;

import com.view.listview.SwipeListView;

import com.view.pop.ActionItem;

import com.view.pop.QuickAction;

import android.os.Bundle;

import android.view.View;

import android.widget.TextView;

import android.app.Activity;

import android.content.Intent;

public class MainActivity extends Activity{

	//listview的适配器

	private RecentAdapter mAdapter;

	//listview数据源

	public  LinkedList<RecentItem> mRecentDatas;

	//自己定义的listview

	private SwipeListView mRecentListView;

	private TextView mEmpty;

	private int mClickItem = -1;

	// 点击item弹出

	protected QuickAction mItemClickQuickAction = null;

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.activity_main);

		initView(savedInstanceState);

		initPop();

	}

	//单击listview某一项时，能够弹出pop。QuickAction实现类是继承PopupWindows

	private void initPop() {

		// 设置Action

		mItemClickQuickAction = new QuickAction(this, QuickAction.VERTICAL);

		ActionItem pointItem = new ActionItem(1, "具体信息", null);

		ActionItem areaItem = new ActionItem(2, "信息2", null);

		pointItem.setIcon(null);

		areaItem.setIcon(null);

		mItemClickQuickAction.addActionItem(pointItem);

		mItemClickQuickAction.addActionItem(areaItem);

		mItemClickQuickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {

			@Override

			public void onItemClick(QuickAction source, int pos, int actionId) {

				if (pos == 0) {

					Intent intent = new Intent(source.GetActionItemsGroup().getContext(),ListViewItemShowActivity.class);

					RecentItem item = new RecentItem();

					item = mRecentDatas.get(mClickItem);

					Bundle bundle = new Bundle();

//					bundle.putString("HeadImg", mImageUrls[mClickItem]);

					bundle.putInt("NewNum", item.getNewNum());

					bundle.putString("Name", item.getName());

					intent.putExtras(bundle);

					startActivity(intent);

				}

				mItemClickQuickAction.dismiss();

			}

		});

	}

	private void initView(Bundle savedInstanceState) {

		mRecentListView = (SwipeListView) findViewById(R.id.recent_listview);

		mRecentDatas = getRecentList();

		mAdapter = new RecentAdapter(this, mRecentDatas, mRecentListView);

		mRecentListView.setAdapter(mAdapter);

		mEmpty = (TextView) findViewById(R.id.empty);

		mRecentListView.setEmptyView(mEmpty);

		mRecentListView

				.setSwipeListViewListener(new BaseSwipeListViewListener() {

					@Override

					public void onClickFrontView(View view, int position) {

						mClickItem = position;

						mItemClickQuickAction.show(view);

					}

					@Override

					public void onClickBackView(int position) {

						mRecentListView.closeOpenedItems();// 关闭打开的项

					}

					@Override

					public void onDismiss(int[] reverseSortedPositions) {

						for (int position : reverseSortedPositions) {

							mAdapter.remove(position);

						}

					}

				});

	}

	public LinkedList<RecentItem> getRecentList() {

		LinkedList<RecentItem> list = new LinkedList<RecentItem>();

		nameArray = getResources().getStringArray(R.array.jazzy_effects_ch);

		for (int i = 0; i < 20; i++) {

//			int icon = heads[i];

			String name = nameArray[i];

			int num = numArray[i];

			RecentItem item = new RecentItem(name, 0, num);

			list.add(item);

		}

		Collections.sort(list);// 降序

		return list;

	}

	public static  int[] numArray = { 21,67,65,8,54,67,23,78,98,54,67,23,67,423,23,67,90,12,34,56,978};

	public static String[] nameArray = new String[21];

}

四、最后别忘了AndroidManifest.xml配置网络权限，以及application

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application

        android:name="com.main.listviewsideslip.MyApplication"

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >
