Question

我的应用程序用户最多可以选择6张图片，在应用程序的最后，我想将这些图片添加到相应的电子邮件地址的电子邮件中。

系统有效，但是当我添加时：

i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

gmail发出此错误：'cyk：无法创建本地附件'

经过一些测试后我发现这是由于并非所有图像都存在，如果我添加所有图像，它只发送最后一个。

这是代码：

 public void SendButtonDown(View v){
    Intent intent = getIntent();

    Uri MAIL_IMAGES_URI = Uri.parse("file://"+MAIL_IMAGES);
    Uri MAIL_IMAGES_URI2 = Uri.parse("file://"+MAIL_IMAGES2);
    Uri MAIL_IMAGES_URI3 = Uri.parse("file://"+MAIL_IMAGES3);
    Uri MAIL_IMAGES_URI4 = Uri.parse("file://"+MAIL_IMAGES4);
    Uri MAIL_IMAGES_URI5 = Uri.parse("file://"+MAIL_IMAGES5);
    Uri MAIL_IMAGES_URI6 = Uri.parse("file://"+MAIL_IMAGES6);

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("message/rfc822");
    i.putExtra(Intent.EXTRA_EMAIL   , new String[]{"testmail@gmail.com"});
    i.putExtra(Intent.EXTRA_SUBJECT , "Subject");
    i.putExtra(Intent.EXTRA_TEXT    , textVar);
    i.setType("application/image");


    i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI2);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI3);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI4);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI5);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI6);


    try {
        startActivity(Intent.createChooser(i, "Send mail..."));
    } catch (android.content.ActivityNotFoundException ex){
        Toast.makeText(AanbiedenStap3.this, "no email installed", 
        Toast.LENGTH_SHORT).show();
    }
    finish();
}
}

我修复了应用，万一你遇到这个问题，这里是修复：

public void SendButtonDown(View v){
    Intent intent = getIntent();

    List<String> filePaths = new ArrayList<>();
    if(MAIL_IMAGES != null) {
        filePaths.add(MAIL_IMAGES);
    }
    if(MAIL_IMAGES2 != null) {
        filePaths.add(MAIL_IMAGES2);
    }
    if(MAIL_IMAGES3 != null) {
        filePaths.add(MAIL_IMAGES3);
    }
    if(MAIL_IMAGES4 != null) {
        filePaths.add(MAIL_IMAGES4);
    }
    if(MAIL_IMAGES5 != null) {
        filePaths.add(MAIL_IMAGES5);
    }
    if(MAIL_IMAGES6 != null) {
        filePaths.add(MAIL_IMAGES6);
    }

    final Intent i = new Intent(Intent.ACTION_SEND_MULTIPLE);
    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_EMAIL   , new String[]{"testmail@gmail.com"});
    i.putExtra(Intent.EXTRA_SUBJECT , "subject");
    i.putExtra(Intent.EXTRA_TEXT    , data);

    ArrayList<Uri> uris = new ArrayList<>();

    for (String file : filePaths){
        File fileIn = new File(file);
        Uri u = Uri.fromFile(fileIn);
        uris.add(u);
    }
    i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    i.putExtra(Intent.EXTRA_STREAM, uris);
    startActivity(Intent.createChooser(i, "Send mail..."));

    finish();
}
}
