Android系统自带分享

目前Android开发分享功能用的比较多的时SharedSDK和友盟分享,其实Android系统已经提供了分享功能,而且更轻量级,用起来更方便,基本可以实现大部分的分享功能.直接贴上代码

package com.shutter.Utils.shareUitl;import android.app.Activity;import android.content.ComponentName;import android.content.ContentResolver;import android.content.ContentValues;import android.content.Context;import android.content.Intent;import android.net.Uri;import android.provider.MediaStore;import android.widget.Toast;/** * Created by yj on 2015/10/12. */public class ShareUtil {    /**     *国外社交的分享     *      由于国外的Ins,FB,MS几大app,通过意图过滤得到的要传递发送图片的Activity都只有一个,即分享界面的Activity,故这里只需要包名即可     * @param activity     * @param packageName 要分享的国外的社交app(Ins,FB,MS)     * @param fileUri 分享图片的Uri     */    public static void shareImageForeign(Activity activity,String packageName,Uri fileUri){        Intent mIntent = new Intent(Intent.ACTION_SEND);        mIntent.setType("image/*");        mIntent.putExtra(Intent.EXTRA_SUBJECT, "shareImage");        mIntent.setPackage(packageName);        mIntent.putExtra(Intent.EXTRA_STREAM, fileUri);        try {            activity.startActivity(Intent.createChooser(mIntent, activity.getTitle()));        } catch (android.content.ActivityNotFoundException e) {            Toast.makeText(activity, "To be share,please install this software: " + packageName,                    Toast.LENGTH_SHORT).show();        }    }    /**     * 国内几大社交的分享     *      由于国内几大社交app(QQ,空间,微信,朋友圈,微博等),通过意图过滤得到的要传递图片的Activity不只一个(例如QQ会出现发送,发送到电脑;微信会出现发送和收藏),故这里还需要制定具体分享     *      界面的全类名,才能实现快速分享     * @param context     * @param packageName 要分享的社交app的包名     * @param shareActivityName 分享界面Activity的全类名     * @param fileUri 分享图片的Uri     */    public static void  shareImageChina(Context context,String packageName, String shareActivityName , Uri fileUri){        Intent intent = new Intent(Intent.ACTION_SEND);        intent.setType("image/*");        intent.putExtra(Intent.EXTRA_STREAM, fileUri);        intent.putExtra(Intent.EXTRA_SUBJECT, "shareImage");        intent.putExtra(Intent.EXTRA_TITLE, "图片标题");        intent.setComponent((new ComponentName("packageName", "ActivityName")));       context.startActivity(intent);    }    /**     * 保存视频文件到本地相册,并生成缩略图,避免分享时没有缩略图而显示为黑色     * @param path     */    public static void saveSdScan(String path,Context context){//        final Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(path, MediaStore.Images.Thumbnails.MICRO_KIND); //生成缩略图        ContentValues localContentValues = new ContentValues();        localContentValues.put("_data", path);        localContentValues.put("description", "save video ---");        localContentValues.put("mime_type", "video/mp4");        ContentResolver localContentResolver = context.getContentResolver();        Uri localUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;        localContentResolver.insert(localUri, localContentValues);//                MediaStore.Images.Media.insertImage(localContentResolver,bitmap,"thumbnail","thumbnail for video"); //这个是给图片添加缩略图    }    /**     * 国外视频的分享     *   国外app(Ins,FB,MS)支持直接分享视频的     * @param activity     * @param packageName     * @param fileUri     */    public static void shareVideoForeign(Activity activity,String packageName,Uri fileUri){        //保存视频到相册以便分享        saveSdScan(fileUri.getPath(), activity);        Intent mIntent = new Intent(Intent.ACTION_SEND);        mIntent.setType("video/*");        mIntent.putExtra(Intent.EXTRA_SUBJECT, "shareVideo");        mIntent.setPackage(packageName);        mIntent.putExtra(Intent.EXTRA_STREAM, fileUri);        try {            activity.startActivity(Intent.createChooser(mIntent, activity.getTitle()));        } catch (android.content.ActivityNotFoundException e) {            Toast.makeText(activity, "To be share,please install this software: " + packageName,                    Toast.LENGTH_SHORT).show();        }    }    /**     *  国内视频的分享     *       目前国内只支持QQ,微信的直接发送视频,其他的(空间,朋友圈,微博)都需要借助于服务器,需要上传到服务器上,再将Url分享出去     * @param context     * @param packageName     * @param shareActivityName     * @param fileUri     */    public static void  shareVideoChina(Context context,String packageName, String shareActivityName , Uri fileUri){        Intent intent = new Intent(Intent.ACTION_SEND);        intent.setType("video/*");        intent.putExtra(Intent.EXTRA_STREAM, fileUri);        intent.putExtra(Intent.EXTRA_SUBJECT, "shareVideo");        intent.putExtra(Intent.EXTRA_TITLE, "视频标题");        intent.setComponent((new ComponentName("packageName", "ActivityName")));        context.startActivity(intent);    }}

下面再给出国内和国外几大社交app的包名和类名
