Android - 分享Facebook,Twitter,Mail,ecc

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"));

是的,你可以...你只需要知道应用程序的确切包名称:

  • Facebook - “com.facebook.katana”
  • Twitter - “com.Twitter.Android”
  • Instagram - “com.instagram.Android”
  • Pinterest - “com.pinterest”

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 使用ACTION_SEND Intent在Android中共享内容

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,它将文本的正文在Twitter,G邮件中挂起..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

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

对于Facebook应用程序使用Facebook SDK

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 SDKTwitter4J

Ovidiu Latcu

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();
        }


    }

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"));
