Android通过第三方应用将自己的应用信息分享出去

     通过第三方应用将自己应用信息分享出去。贴代码

    1， //点击分享之后弹出的对话框，这个对话框是我自己定义的    

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");//分享的类型
AlertDialog.Builder customDia = new AlertDialog.Builder(activity, R.style.share_dialog);//自己定义的对话框
final View viewDia = LayoutInflater.from(activity).inflate(R.layout.dialog, null);//布局里面是gridview
//        ImageView shareClose = (ImageView)viewDia.findViewById(R.id.share_close);
GridView listView =(GridView)viewDia.findViewById(R.id.grid_view);
final ShareAdapter adapter = new ShareAdapter(activity, intent);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {
Intent intent = adapter.getIntentForPosition(position);
SharedPreferences share = activity.getSharedPreferences("service_data", Context.MODE_PRIVATE);
String url = /*share.getString("shareUrl", "")*/"";
String local = activity.getResources().getConfiguration().locale.getCountry();
String des = "";
if("".equals(url) || url == null){
if ("CN".equals(local)) {
url = "http://www.wanyiwan.com";//分享的信息区分了语言
} else {
url = "https://wanyiwan.com";
}
if("".equals(des) || des == null){
des =activity.getResources().getString(R.string.des) ;
}
}
intent.putExtra(Intent.EXTRA_TEXT, des + "\n "+ url);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_SINGLE_TOP);
activity.startActivity(intent);

     2，适配器  

public ShareAdapter(Context context, Intent intent) {
mContext = context;
mPackageManager = mContext.getPackageManager();
mIntent = new Intent(intent);
mInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
packageManager = mContext.getPackageManager();//拿到包管理器，它负责拿到图标
mList = packageManager.queryIntentActivities(intent, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);//负责通过意图拿到能分享信息的应用

mDisplayResolveInfoList = new ArrayList<DisplayResolveInfo>();
if (mList == null || mList.isEmpty()) {
mList = new ArrayList<ResolveInfo>();
}

final int N = mList.size();
for (int i = 0; i < N; i++) {
ResolveInfo ri = mList.get(i);
CharSequence label = ri.loadLabel(mPackageManager);
DisplayResolveInfo d = new DisplayResolveInfo(ri, null, null, label, null, new ComponentName(ri.activityInfo.packageName, ri.activityInfo.name));
if (!mDisplayResolveInfoList.contains(d)) {
mDisplayResolveInfoList.add(d);
}
}

//        comparison();
Collections.sort(mDisplayResolveInfoList, new SharedAppComparator());
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if(convertView == null) {
convertView = mInflater.inflate(R.layout.share_item, null);
viewHolder = new ViewHolder();
viewHolder.imageView = (ImageView)convertView.findViewById(R.id.icon_share);
viewHolder.textView = (TextView)convertView.findViewById(R.id.title_share);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder)convertView.getTag();
}
DisplayResolveInfo info = mDisplayResolveInfoList.get(position);
viewHolder.imageView.setImageDrawable(info.mResoleInfo.loadIcon(packageManager));//拿到图标
Log.e("share", "share icon==== " + info.mResoleInfo.loadIcon(packageManager) + " share title = " + info.mLabel);
viewHolder.textView.setText(info.mLabel);//拿到标题
return convertView;
}

public ResolveInfo getResolveInfo(int index){//封装了一层
if(mDisplayResolveInfoList == null){
return null;
}
DisplayResolveInfo d = mDisplayResolveInfoList.get(index);
if(d.mResoleInfo == null){
return null;
}
return d.mResoleInfo;
}

//返回跳转intent
public Intent getIntentForPosition(int index) {
if(mDisplayResolveInfoList == null){
return null;
}
DisplayResolveInfo d = mDisplayResolveInfoList.get(index);
Intent i = new Intent(d.mIntent == null ? mIntent : d.mIntent);
i.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT | Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP);
if(d.mResoleInfo != null){
ActivityInfo a = d.mResoleInfo.activityInfo;
i.setComponent(new ComponentName(a.applicationInfo.packageName, a.name));
}
return i;
}

/**
* 打包数据 vo
* @author
*/
class DisplayResolveInfo {//封装
private Intent mIntent;
private ResolveInfo mResoleInfo;
private CharSequence mLabel;
private Drawable mDrawable;
private ComponentName cn;

private int position = Integer.MAX_VALUE;

DisplayResolveInfo(ResolveInfo resolveInfo, Intent intent,
CharSequence info, CharSequence label, Drawable d,
ComponentName cn) {
this.mIntent = intent;
this.mResoleInfo = resolveInfo;
this.mLabel = label;
this.mDrawable = d;
this.cn = cn;
}

}

   如果想把自己的应用设定为能发送分享信息的应用，可以将activity的

<intent-filter>
<action android:name="android.intent.action.SEND" />

<data android:mimeType="text/plain" />

<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

，Android就可以通过这个类型将应用分为能发送信息的应用
