只需要分享一个动态文本字符串的URL到应用程序.
Android的原始
Android分享意图设置正确,并且使用Twitter,Gmail等功能完美无缺,但是很多人会猜测,它与Facebook无效.显然,因为Facebook不会接受intent.EXTRA_TEXT字段中的文本,只有一个URL.
那么我的问题是：有没有办法根据他们选择分享哪种方法来分支股份意向追加？例如,如果他们通过gmail或Twitter共享,请使用现有的字符串URL(所需选项)EXTRA_TEXT,但如果他们选择通过Facebook共享,则只能使用URL作为EXTRA_TEXT.
不是真的想实现Facebook Android SDK这样一个简单的任务,内置在Android本身.
欣赏你的时间和建议.
尝试这样的东西,但它显然失败了,因为它只检查共享选项是否存在(当共享弹出时,不是在他们点击共享方法后),它在选择方法时不响应.
String shareBody = "app string text " + act_txt + " more text! Get the app at http://www.appurl.com";
PackageManager pm = view.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent,0);
for(final ResolveInfo app : activityList) {
Log.i(TAG,"app.actinfo.name: " + app.activityInfo.name);
//if((app.activityInfo.name).contains("facebook")) {
if("com.facebook.katana.ShareLinkActivity".equals(app.activityInfo.name)) {
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT,"http://www.appurl.com");
startActivity(Intent.createChooser(sharingIntent,"Share idea"));
break;
} else {
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"app name");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT,shareBody);
startActivity(Intent.createChooser(sharingIntent,"Share"));
break;
}
}
解决方法
找到一个解决方案,在这个SO问题要求别的东西：

尝试发布我在这里的原始问题是接近的.在可能的shareIntent列表的周期内,您需要创建针对特定共享选项的新共享意图(如Facebook或Twitter)
这是一个最终的工作解决方案,如果选择了Facebook,则只共享一个URL,否则共享完整的文本字符串url：
public void shareIt(View view){
//sharing implementation
List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "string of text " + txt_var + " more text! Get the app at http://someapp.com";
PackageManager pm = view.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent,0);
for(final ResolveInfo app : activityList) {
String packageName = app.activityInfo.packageName;
Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
targetedShareIntent.setType("text/plain");
targetedShareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"share");
if(TextUtils.equals(packageName,"com.facebook.katana")){
targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT,"http://someurl.com");
} else {
targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT,shareBody);
}
targetedShareIntent.setPackage(packageName);
targetedShareIntents.add(targetedShareIntent);
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0),"Share Idea");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,targetedShareIntents.toArray(new Parcelable[]{}));
startActivity(chooserIntent);
}
