Android原生分享功能的思考与实现

因为公司的需求，最近一直在做分享这一块的功能。大概有这样几种思路：

1.使用Intent调用andoird原生的分享功能；

2.使用第三方的sdk，比如ShareSdk或者友盟；

3.去对应的平台下载jar包，参考官方设计文档写出自己的分享demo，但这种一般也比较复杂，尤其搞不懂qq和微信一家公司的，为什么微信那么麻烦。

不废话了，直接上代码：

一. 新建ShareUtil.java类

import java.io.File;import android.content.ComponentName;import android.content.Context;import android.content.Intent;import android.content.pm.PackageManager;import android.content.pm.PackageManager.NameNotFoundException;import android.net.Uri;import android.text.TextUtils;import android.widget.Toast;public class ShareUtil {private Context context;public ShareUtil(Context context) {this.context = context;}public static final String WEIXIN_PACKAGE_NAME = "";public static final String QQ_PACKAGE_NAME = "";//public static final String ;/** * 分享文字 *

Intent();intent.setAction(Intent.ACTION_SEND);intent.setType("text/plain");//if(null != className && null != packageName && !TextUtils.isEmpty(className) && !TextUtils.isEmpty(packageName)){////}else {//if(null != packageName && !TextUtils.isEmpty(packageName)){//intent.setPackage(packageName);//}//}if(stringCheck(className) && stringCheck(packageName)){ComponentName componentName = new

packageName,String className,File file){if(file.exists()){Uri uri = Uri.fromFile(file);Intent intent = new Intent();intent.setAction(Intent.ACTION_SEND);intent.setType("image/*");if(stringCheck(packageName) && stringCheck(className)){intent.setComponent(new ComponentName(packageName, className));}else if (stringCheck(packageName)) {intent.setPackage(packageName);}intent.putExtra(Intent.EXTRA_STREAM, uri);Intent chooserIntent = Intent.createChooser(intent, "分享到:");context.startActivity(chooserIntent);}else {Toast.makeText(context, "文件不存在", 1000).show();}}/** * 分享音乐 */public void shareAudio(String packageName,String className,File file){if(file.exists()){Uri uri = Uri.fromFile(file);Intent intent = new Intent();intent.setAction(Intent.ACTION_SEND);intent.setType("audio/*");if(stringCheck(packageName) && stringCheck(className)){intent.setComponent(new ComponentName(packageName, className));}else if (stringCheck(packageName)) {intent.setPackage(packageName);}intent.putExtra(Intent.EXTRA_STREAM, uri);Intent chooserIntent = Intent.createChooser(intent, "分享到:");context.startActivity(chooserIntent);}else {Toast.makeText(context, "文件不存在", 1000).show();}}/** * 分享视频 */public void shareVideo(String

Intent();ComponentName comp = new ComponentName(packageName, className);intent.setComponent(comp);intent.setAction(Intent.ACTION_SEND);intent.setType("image/*");intent.putExtra(Intent.EXTRA_STREAM, uri);intent.putExtra("Kdescription", title);context.startActivity(intent);}else{Toast.makeText(context, "文件不存在", Toast.LENGTH_LONG).show();}}/** * 是否安装分享app * @param packageName */public boolean checkInstall(String packageName){try {context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);return true;} catch (NameNotFoundException e) {e.printStackTrace();Toast.makeText(context, "请先安装应用app", 1500).show();return false;}}/** * 跳转官方安装网址 */public void toInstallWebView(String url){Intent intent = new Intent();intent.setAction(Intent.ACTION_VIEW);intent.setData(Uri.parse(url));context.startActivity(intent);}public static boolean stringCheck(String str){if(null != str && !TextUtils.isEmpty(str)){return true;}else {return false;}}}

二. MainActivity.java类

import java.io.File;import android.app.Activity;import android.os.Bundle;import android.os.Environment;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class MainActivity extends Activity implements OnClickListener {Button btnQQ;Button btnWX;Button btnMore;Button btnWxFriendText;Button btnQQFriendText;Button btnWxFriendImg;Button btnQQFriendImg;Button btnWxFriendAudio;Button btnQQFriendAduio;Button btnWxFriendVideo;Button btnQQFriendVideo;ShareUtil shareUtil;private Button btn_wxCircle_img;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btnQQ = (Button) findViewById(R.id.btn_qq);btnWX = (Button) findViewById(R.id.btn_wx);btnMore = (Button) findViewById(R.id.btn_more);btnWxFriendText = (Button) findViewById(R.id.btn_wxFriend);btnQQFriendText = (Button) findViewById(R.id.btn_qqFriend);btnWxFriendImg = (Button) findViewById(R.id.btn_wxFriend_img);btnQQFriendImg = (Button) findViewById(R.id.btn_qqFriend_img);btnWxFriendAudio = (Button) findViewById(R.id.btn_wxFriend_audio);btnQQFriendAduio = (Button) findViewById(R.id.btn_qqFriend_audio);btnWxFriendVideo = (Button) findViewById(R.id.btn_wxFriend_video);btnQQFriendVideo = (Button) findViewById(R.id.btn_qqFriend_video);btn_wxCircle_img = (Button) findViewById(R.id.btn_wxCircle_img);btnQQ.setOnClickListener(this);btnWX.setOnClickListener(this);btnMore.setOnClickListener(this);btnWxFriendText.setOnClickListener(this);btnQQFriendText.setOnClickListener(this);btnWxFriendImg.setOnClickListener(this);btnQQFriendImg.setOnClickListener(this);btnWxFriendAudio.setOnClickListener(this);btnQQFriendAduio.setOnClickListener(this);btnWxFriendVideo.setOnClickListener(this);btnQQFriendVideo.setOnClickListener(this);btn_wxCircle_img.setOnClickListener(this);shareUtil = new ShareUtil(this);}@Overridepublic void onClick(View v) {String testImgPath = "/storage/emulated/legacy/display-client/picture/my.png";String testImagePath = Environment.getExternalStorageDirectory()+ "/img.jpg";String testAudioPath = Environment.getExternalStorageDirectory()+ "/audio.mp3";String testVideoPath = Environment.getExternalStorageDirectory()+ "/video.mp4";File file = new File(testImgPath);File fileImage = new File(testImagePath);File fileAudio = new File(testAudioPath);File fileVideo = new File(testVideoPath);switch (v.getId()) {// qq&文字case R.id.btn_qq:shareUtil.shareText("com.tencent.mobileqq", null, "这是一条分享信息","分享标题", "分享主题");break;// 微信&文字case R.id.btn_wx:shareUtil.shareText("com.tencent.mm", null, "这是一条分享信息", "分享标题","分享主题");break;// 所有&文字case R.id.btn_more:shareUtil.shareText(null, null, "这是一条分享信息", "分享标题", "分享主题");break;// 微信朋友&文字case R.id.btn_wxFriend:if (shareUtil.checkInstall("com.tencent.mm")) {shareUtil.shareText("com.tencent.mm","com.tencent.mm.ui.tools.ShareImgUI","http://www.aiipu.com/", "分享标题", "分享主题");} else {shareUtil.toInstallWebView("http://weixin.qq.com/download");}break;// qq朋友&文字case R.id.btn_qqFriend:if (shareUtil.checkInstall("com.tencent.mobileqq")) {shareUtil.shareText("com.tencent.mobileqq","com.tencent.mobileqq.activity.JumpActivity","http://www.aiipu.com/", "分享标题", "分享主题");} else {shareUtil.toInstallWebView("http://im.qq.com/mobileqq/");}break;// 微信朋友&图片case R.id.btn_wxFriend_img:shareUtil.shareImg("com.tencent.mm","com.tencent.mm.ui.tools.ShareImgUI", fileImage);break;// qq朋友&图片case R.id.btn_qqFriend_img:shareUtil.shareImg("com.tencent.mobileqq","com.tencent.mobileqq.activity.JumpActivity", fileImage);break;case R.id.btn_wxFriend_audio:shareUtil.shareAudio("com.tencent.mm","com.tencent.mm.ui.tools.ShareImgUI", fileAudio);break;case R.id.btn_qqFriend_audio:shareUtil.shareAudio("com.tencent.mobileqq","com.tencent.mobileqq.activity.JumpActivity", fileAudio);break;case R.id.btn_wxFriend_video:shareUtil.shareVideo("com.tencent.mm","com.tencent.mm.ui.tools.ShareImgUI", fileVideo);break;case R.id.btn_qqFriend_video:shareUtil.shareVideo("com.tencent.mobileqq","com.tencent.mobileqq.activity.JumpActivity", fileVideo);break;case R.id.btn_wxCircle_img:shareUtil.shareImgToWXCircle("狗狗图片", "com.tencent.mm","com.tencent.mm.ui.tools.ShareToTimeLineUI", fileImage);break;}}}

三.布局文件activity_main.xml

其中微信的分享只能分享文字和图片，不能单独分享图片或者文字。
