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.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
	 * @param packageName
	 * @param content
	 * @param title
	 * @param subject
	 */
	public void shareText(String packageName,String className,String content,String title,String subject){
			Intent intent =new 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);
	//			}
	//		}

		}
	
	/**

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;

	@Override
	protected 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);

		btnQQFriendText.setOnClickListener(this);
		btnWxFriendImg.setOnClickListener(this);
		btnQQFriendImg.setOnClickListener(this);

		btnQQFriendAduio.setOnClickListener(this);

		btn_wxCircle_img.setOnClickListener(this);

		shareUtil = new ShareUtil(this);
	}

	@Override
	public void onClick(View v) {
		String testImgPath = "/storage/emulated/legacy/display-client/picture/my.png";

		String testImagePath = Environment.getExternalStorageDirectory()
				+ "/img.jpg";

		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;

			if (shareUtil.checkInstall("com.tencent.mm")) {
				shareUtil.shareText("com.tencent.mm",

			}
			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.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。
