我需要开发一个具有共享功能的应用程序。我必须分享Facebook，Twitter，电子邮件和其他服务。
我怎样才能做到这一点？网上有图书馆吗？对于iOS开发，有ShareKit，但对于Android？
谢谢 ：）
Paresh Mayani的回答大多是正确的。只需使用Broadcast Intent让系统和所有其他应用程序选择内容将以何种方式共享。
要共享文本，请使用以下代码：
String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));
sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"your subject" );
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "your text");
startActivity(Intent.createChooser(sharingIntent, ""));
这会有所帮助
1-首先定义此常量
public static final String FACEBOOK_PACKAGE_NAME = "com.facebook.katana";
public static final String TWITTER_PACKAGE_NAME = "com.twitter.android";
public static final String INSTAGRAM_PACKAGE_NAME = "com.instagram.android";
public static final String PINTEREST_PACKAGE_NAME = "com.pinterest";
public static final String WHATS_PACKAGE_NAME = "com.whatsapp";
2-秒使用此方法
public static void shareAppWithSocial(Context context, String application, String title,
String description) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setPackage(application);
intent.putExtra(android.content.Intent.EXTRA_TITLE, title);
intent.putExtra(Intent.EXTRA_TEXT, description);
intent.setType("text/plain");
try {
// Start the specific social application
context.startActivity(intent);
} catch (android.content.ActivityNotFoundException ex) {
// The application does not exist
Toast.makeText(context, "app have not been installed.", Toast.LENGTH_SHORT).show();
}
}
是的，你可以...你只需要知道应用程序的确切包名称：
你可以像这样创建意图
Intent intent = context.getPackageManager().getLaunchIntentForPackage(application);
if (intent != null) {
// The application exists
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage(application);
shareIntent.putExtra(android.content.Intent.EXTRA_TITLE, title);
shareIntent.putExtra(Intent.EXTRA_TEXT, description);
// Start the specific social application
context.startActivity(shareIntent);
} else {
// The application does not exist
// Open GooglePlay or use the default system picker
}
我想你想给分享按钮，点击哪个合适的媒体/网站选项应该与它分享。在Android中，您需要为此创建createChooser。
分享文字：
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "This is the text that will be shared.");
startActivity(Intent.createChooser(sharingIntent,"Share using"));
共享二进制对象（图像，视频等）
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
仅供参考，以上代码均来自Sharing content in Android using ACTION_SEND Intent
用这个
Facebook - "com.facebook.katana"
Twitter - "com.twitter.android"
Instagram - "com.instagram.android"
Pinterest - "com.pinterest"
SharingToSocialMedia("com.facebook.katana")
public void SharingToSocialMedia(String application) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, bmpUri);
boolean installed = checkAppInstall(application);
if (installed) {
intent.setPackage(application);
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),
"Installed application first", Toast.LENGTH_LONG).show();
}
}
private boolean checkAppInstall(String uri) {
PackageManager pm = getPackageManager();
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
}
return false;
}
ACTION_SEND将对所有人正常工作，它需要文本的正文在twitter，G mail中挂起..但它失败For Face Book页面...它是Facebook android SDK中的已知错误..但它们仍然没有'修好了
ACTION_SEND只会为您提供使用GMail，YahooMail等发送的选项（手机上安装的任何可以执行ACTION_SEND的应用程序）。如果你想在Facebook或Twitter上分享，你需要为每个按钮分配自定义按钮，并使用自己的SDK，如Facebook SDK或Twitter4J。
我认为以下代码将有所帮助......
public void btnShareClick(View v) {
// shareBtnFlag = 1;
Dialog d = new Dialog(DrawAppActivity.this);
d.requestWindowFeature(d.getWindow().FEATURE_NO_TITLE);
d.setCancelable(true);
d.setContentView(R.layout.sharing);
final Button btnFacebook = (Button) d.findViewById(R.id.btnFacebook);
final Button btnEmail = (Button) d.findViewById(R.id.btnEmail);
btnEmail.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
if (!btnEmail.isSelected()) {
btnEmail.setSelected(true);
} else {
btnEmail.setSelected(false);
}
saveBtnFlag = 1;
// Check if email id is available-------------
AccountManager manager = AccountManager
.get(DrawAppActivity.this);
Account[] accounts = manager.getAccountsByType("com.google");
Account account = CommonFunctions.getAccount(manager);
if (account.name != null) {
emailSendingTask eTask = new emailSendingTask();
eTask.execute();
if (CommonFunctions.createDirIfNotExists(getResources()
.getString(R.string.path)))

tempImageSaving(
getResources().getString(R.string.path),
getCurrentImage());
}

sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("application/octet-stream");
sendIntent.setType("image/jpeg");
sendIntent.putExtra(Intent.EXTRA_EMAIL,
new String[] { account.name });
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Drawing App");
sendIntent.putExtra(Intent.EXTRA_TEXT, "Check This Image");
sendIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file://" + tempPath.getPath()));
List<ResolveInfo> list = getPackageManager()
.queryIntentActivities(sendIntent,
PackageManager.MATCH_DEFAULT_ONLY);
if (list.size() != 0) {
startActivity(Intent.createChooser(sendIntent,
"Send Email Using:"));
}

对于Facebook应用程序使用Facebook SDK
这将让你在什么应用程序上分享你的应用程序：
try
{ Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_SUBJECT, "My application name");
String sAux = "\nLet me recommend you this application\n\n";
sAux = sAux + "https://play.google.com/store/apps/details?id=Orion.Soft \n\n";
i.putExtra(Intent.EXTRA_TEXT, sAux);
startActivity(Intent.createChooser(i, "choose one"));
String message = "This is testing."
Intent shareText = new Intent(Intent.ACTION_SEND);
shareText .setType("text/plain");
shareText .putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(shareText , "Title of the dialog the system will open"));
