Android：使用Intent共享纯文本（向所有消息传递应用程序）

我正在尝试使用意图共享一些文本：

Intent i = new Intent(android.content.Intent.ACTION_SEND);
i.setType("text/plain");  
i.putExtra(android.content.Intent.EXTRA_TEXT, "TEXT");

并与选择器一起变形：

startActivity(Intent.createChooser(sms, getResources().getString(R.string.share_using)));

有用！但仅适用于电子邮件应用程序。
我需要的是所有消息传递应用程序的一般意图：电子邮件，短信，即时消息（Whatsapp，Viber，Gmail，SMS ...）尝试使用android.content.Intent.ACTION_VIEW 并且不使用i.setType("vnd.android-dir/mms-sms");任何帮助...

（"vnd.android-dir/mms-sms"仅使用短信共享！）

使用以下代码：

    /*Create an ACTION_SEND Intent*/
    Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    /*This will be the actual content you wish you share.*/
    String shareBody = "Here is the share content body";
    /*The type of the content is text, obviously.*/
    intent.setType("text/plain");
    /*Applying information Subject and Body.*/
    intent.putExtra(android.content.Intent.EXTRA_SUBJECT, getString(R.string.share_subject));
    intent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
    /*Fire!*/
    startActivity(Intent.createChooser(intent, getString(R.string.share_using)));

执行此操作的新方法是使用ShareCompat.IntentBuilder，如下所示：

// Create and fire off our Intent in one fell swoop
ShareCompat.IntentBuilder
        // getActivity() or activity field if within Fragment
        .from(this) 
        // The text that will be shared
        .setText(textToShare)
        // most general text sharing MIME type
        .setType("text/plain") 
        .setStream(uriToContentThatMatchesTheArgumentOfSetType)
        /*
         * [OPTIONAL] Designate a URI to share. Your type that 
         * is set above will have to match the type of data
         * that your designating with this URI. Not sure
         * exactly what happens if you don't do that, but 
         * let's not find out.
         * 
         * For example, to share an image, you'd do the following:
         *     File imageFile = ...;
         *     Uri uriToImage = ...; // Convert the File to URI
         *     Intent shareImage = ShareCompat.IntentBuilder.from(activity)
         *       .setType("image/png")
         *       .setStream(uriToImage)
         *       .getIntent();
         */
        .setEmailTo(arrayOfStringEmailAddresses)
        .setEmailTo(singleStringEmailAddress)
        /*
         * [OPTIONAL] Designate the email recipients as an array
         * of Strings or a single String
         */ 
        .setEmailTo(arrayOfStringEmailAddresses)
        .setEmailTo(singleStringEmailAddress)
        /*
         * [OPTIONAL] Designate the email addresses that will be 
         * BCC'd on an email as an array of Strings or a single String
         */ 
        .addEmailBcc(arrayOfStringEmailAddresses)
        .addEmailBcc(singleStringEmailAddress)
        /* 
         * The title of the chooser that the system will show
         * to allow the user to select an app
         */
        .setChooserTitle(yourChooserTitle)
        .startChooser();

如果您对使用ShareCompat还有其他疑问，我强烈推荐Google的Android开发倡导者Ian Lake撰写的这篇很棒的文章，以更完整地了解API。您会注意到，我从该文章中借来了一些示例。

如果该文章不能解决您的所有问题，则Android开发者网站上始终存在ShareCompat.IntentBuilder的Javadoc本身。根据clemantiano的评论，我在此API使用示例中添加了更多内容。

这是一个有关在Android中与Intents分享的好例子：

*与Android中的意图共享

//Share text:

Intent intent2 = new Intent(); intent2.setAction(Intent.ACTION_SEND);
intent2.setType("text/plain");
intent2.putExtra(Intent.EXTRA_TEXT, "Your text here" );  
startActivity(Intent.createChooser(intent2, "Share via"));

//via Email:

Intent intent2 = new Intent();
intent2.setAction(Intent.ACTION_SEND);
intent2.setType("message/rfc822");
intent2.putExtra(Intent.EXTRA_EMAIL, new String[]{EMAIL1, EMAIL2});
intent2.putExtra(Intent.EXTRA_SUBJECT, "Email Subject");
intent2.putExtra(Intent.EXTRA_TEXT, "Your text here" );  
startActivity(intent2);

//Share Files:

//Image:

boolean isPNG = (path.toLowerCase().endsWith(".png")) ? true : false;

Intent i = new Intent(Intent.ACTION_SEND);
//Set type of file
if(isPNG)
{
    i.setType("image/png");//With png image file or set "image/*" type
}
else
{
    i.setType("image/jpeg");
}

Uri imgUri = Uri.fromFile(new File(path));//Absolute Path of image
i.putExtra(Intent.EXTRA_STREAM, imgUri);//Uri of image
startActivity(Intent.createChooser(i, "Share via"));
break;

//APK:

File f = new File(path1);
if(f.exists())
{

   Intent intent2 = new Intent();
   intent2.setAction(Intent.ACTION_SEND);
   intent2.setType("application/vnd.android.package-archive");//APk file type  
   intent2.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f) );  
   startActivity(Intent.createChooser(intent2, "Share via"));
}
break;

使用以下方法，只需将主体和主体作为方法的参数传递

public static void shareText(String subject,String body) {
    Intent txtIntent = new Intent(android.content.Intent.ACTION_SEND);
    txtIntent .setType("text/plain");
    txtIntent .putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
    txtIntent .putExtra(android.content.Intent.EXTRA_TEXT, body);
    startActivity(Intent.createChooser(txtIntent ,"Share"));
}

以下是可与电子邮件或消息传递应用程序一起使用的代码。如果您通过电子邮件共享，则主题和正文都将被添加。

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
                sharingIntent.setType("text/plain");

                String shareString = Html.fromHtml("Medicine Name:" + medicine_name +
                        "<p>Store Name:" + “store_name “+ "</p>" +
                        "<p>Store Address:" + “store_address” + "</p>")  .toString();
                                      sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Medicine Enquiry");
                sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareString);

                if (sharingIntent.resolveActivity(context.getPackageManager()) != null)
                    context.startActivity(Intent.createChooser(sharingIntent, "Share using"));
                else {
                    Toast.makeText(context, "No app found on your phone which can perform this action", Toast.LENGTH_SHORT).show();
                }

图片或二进制数据：

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/jpg");
Uri uri = Uri.fromFile(new File(getFilesDir(), "foo.jpg"));
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri.toString());
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

或HTML：

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/html");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml("<p>This is the text shared.</p>"));
startActivity(Intent.createChooser(sharingIntent,"Share using"));

此代码用于通过短信共享

     String smsBody="Sms Body";
     Intent sendIntent = new Intent(Intent.ACTION_VIEW);
     sendIntent.putExtra("sms_body", smsBody);
     sendIntent.setType("vnd.android-dir/mms-sms");
     startActivity(sendIntent);

Gmail共享的100％工作代码

    Intent intent = new Intent (Intent.ACTION_SEND);
    intent.setType("message/rfc822");
    intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"anyMail@gmail.com"});
    intent.putExtra(Intent.EXTRA_SUBJECT, "Any subject if you want");
    intent.setPackage("com.google.android.gm");
    if (intent.resolveActivity(getPackageManager())!=null)
        startActivity(intent);
    else
        Toast.makeText(this,"Gmail App is not installed",Toast.LENGTH_SHORT).show();
