Android 分享到其他app

分手后的思念是犯贱 2022-08-19 08:45 267阅读 0赞

首先介绍一下最简单最常用的分享方式，就是先获取系统里有分享功能的app列表，然后用intent传输一些值过去

![Center][]

下面是获取系统中可分享的app的代码

private List<ResolveInfo> activityList;

private void init() {
    
            PackageManager pm = mContext.getPackageManager();
            Intent clipboardIntent = new Intent(Intent.ACTION_ALL_APPS);
            clipboardIntent.setType("text/plain");
           
            Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
            sharingIntent.setType("text/plain");
    
            activityList = pm.queryIntentActivities(sharingIntent, 0);
            if(activityList==null)return;
            for (int i = 0; i < activityList.size(); i++) {
                JLogUtils.i("Alex","可分享的app是"+activityList.get(i).activityInfo.packageName);
            }
        }

这样就获得了一个装有多个app调用的List

/**
         * 显示可以用于分享的app的对话框列表
         */
        public void show() {
            Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
            sharingIntent.setType("text/plain");
            ShareIntentListAdapter objShareIntentListAdapter = new ShareIntentListAdapter((Activity) mContext, activityList.toArray());
            AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
            builder.setTitle("Share your link");
            builder.setAdapter(objShareIntentListAdapter, new DialogInterface.OnClickListener() {//建立一个listView状的弹出对话框
                public void onClick(DialogInterface dialog, int item) {
                    JLogUtils.i("Alex", "点击了第" + item + "个");
                    ResolveInfo info = (ResolveInfo) activityList.get(item);
                    JLogUtils.i("Alex", "点击的项目是" + info.activityInfo.packageName + "  class是" + info.activityInfo.name);
                    // if email shared by user
                    if (info.activityInfo.packageName.contains("facebook")) {
                        shareFacebook();//faceBook SDK有自己专门的分享方法
                        return;
                    }
                    // start respective activity
                    Intent intent = new Intent(android.content.Intent.ACTION_SEND);
                    intent.setClassName(info.activityInfo.packageName, info.activityInfo.name);
                    intent.setType("text/plain");//除了facebook以外，其他的只发送文本，只把title和content发送出去
                    if (!TextUtils.isEmpty(title)) {
                        JLogUtils.i("Alex", "title是" + title);
                        intent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);//把标题发过去
                    }
                    JLogUtils.i("Alex", "content是" + content);
                    intent.putExtra(android.content.Intent.EXTRA_TEXT, content);//把内容发过去
                    mContext.startActivity(intent);//这里有一个传来的环境变量
                }// end onClick
            });
            AlertDialog alert = builder.create();
            alert.setCancelable(true);
            alert.setCanceledOnTouchOutside(true);
            alert.show();
        }

附适配器的写法

import android.app.Activity;
    import android.content.pm.ResolveInfo;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.ArrayAdapter;
    import android.widget.ImageView;
    import android.widget.TextView;
    
    
    public class ShareIntentListAdapter extends ArrayAdapter{
    
        private final Activity context;
        Object[] items;
    
    
        public ShareIntentListAdapter(Activity context,Object[] items) {
    
            super(context, R.layout.layout_shared, items);
            this.context = context;
            this.items = items;
    
        }// end HomeListViewPrototype
    
        class ShareHolder{
            CustomTextView shareName;
            ImageView imageShare;
    
    
        }
    
        @Override
        public View getView(int position, View view, ViewGroup parent) {
    
            ShareHolder hodler=null;
            if(view==null){
                LayoutInflater inflater = context.getLayoutInflater();
                view=  inflater.inflate(R.layout.layout_shared, null, true);
                hodler=new ShareHolder();
                hodler.imageShare= (ImageView) view.findViewById(R.id.shareImage);
                hodler.shareName= (CustomTextView) view.findViewById(R.id.shareName);
                view.setTag(hodler);
            }else{
                hodler= (ShareHolder) view.getTag();
            }
            // set native name of App to share
            hodler.shareName.setText(((ResolveInfo) items[position]).activityInfo.applicationInfo.loadLabel(context.getPackageManager()).toString());
    
            // share native image of the App to share
            hodler.imageShare.setImageDrawable(((ResolveInfo) items[position]).activityInfo.applicationInfo.loadIcon(context.getPackageManager()));
            return view;
        }// end getView
    
    }// end main onCreate

附，list单个布局的写法

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/categoryCell"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:paddingLeft="15dp"
        android:paddingRight="15dp"
        android:background="@android:color/white" >
        <ImageView
            android:id="@+id/shareImage"
    
            android:layout_width="40dip"
            android:layout_height="40dip"
            android:layout_centerVertical="true"
            />
    
        <TextView
            android:id="@+id/shareName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:layout_marginLeft="10dp"
    
            android:layout_toRightOf="@+id/shareImage"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/black666666"
            
             />
    </RelativeLayout>

下面写一下facebookshare的方法

![Center 1][]

/**
         * 配置要发到facebook的内容
         */
        private void shareFacebook() {
            String link = webUrl;
            String picture = (imageUrl == null ? "" : imageUrl);
            String applicationname = mContext.getResources().getString(R.string.app_name);
            JShareUtils.FacebookStoryEntity entity = new JShareUtils.FacebookStoryEntity();
            JLogUtils.i("Alex","要分享到facebook的entity是"+entity);
            entity.setLink(link);
            entity.setApplicationName(applicationname);
            entity.setDescription(facebookDesc);
            entity.setName(title);
            entity.setCaption("see now on Haha");
            if (imageUrl != null) {
                entity.setPicture(picture);
            }
            JShareUtils.publishFacebookStoryByNativeApp((Activity) mContext, entity, shareHandler);
        }

public static void publishFacebookStoryByNativeApp(Activity activity, FacebookStoryEntity entity, Handler handler) {
            if (activity == null || entity == null) {
                callBackByHandler(handler, HANDLER_WHAT_FACEBOOK_ERROR_INIT, null);
                return;
            }
            try {
                String link = entity.getLink();
                String applicationname = entity.getApplicationName();
                String description = entity.getDescription();
                String name = entity.getName();
                String caption = entity.getCaption();
                String picture = entity.getPicture();
    
                try {
                    FacebookDialog.ShareDialogBuilder shareDialogBuilder = new FacebookDialog.ShareDialogBuilder(activity);//facebook sdk自己的类真的很好用
    
                    if (link != null) {
                        shareDialogBuilder.setLink(link);
                    }
    
                    if (applicationname != null) {
                        shareDialogBuilder.setApplicationName(applicationname);
                    }
    
                    if (description != null) {
                        shareDialogBuilder.setDescription(description);

                        shareDialogBuilder.setCaption(caption);
                    }
    
                    if (picture != null) {

                    }
    
                    if (shareDialogBuilder.canPresent()) {
                        FacebookDialog shareDialog = shareDialogBuilder.build();
                        shareDialog.present();
                    } else {
                        callBackByHandler(handler, HANDLER_WHAT_FACEBOOK_ERROR_UNINSTALLED, null);
                    }

facebook的sdk

dependencies {
        compile project(':libraries:facebook')  
    }

需要引入一个项目当库，facebook项目下载地址：http://download.csdn.net/detail/lvshaorong/9396080

ps：这个库同时也支持facebook的登录功能
