安卓：与图像从ImageView的发送电子邮件 [英] Android: send an email with an image from an ImageView

问题描述

我是新来的计算器。我有一个小问题，我的Andr​​oid应用程序，expecially与触发事件在点击一个ImageView的。本次活动打开一个电子邮件客户端的一些pre-书面文本，并应附有图像的图像。我已经知道，形象应该是之前转换为位图，然后COM pressed并将其发送到电子邮件客户端，但不幸的是我不是一个Android / Java专家，所以我无法找到如何做到这一点。这是电子邮件的方法的code：

I'm new here on stackoverflow. I have a little problem with my Android app, expecially with an ImageView that triggers an event on tap. This event opens an email client with some pre-written text and it should attach the image of the Image. I already know that the image should be converted into a bitmap before, then compressed and send it to the email client, but unfortunatly I'm not an Android/Java expert so I can't find how to do that. This is the code of the email method:

新的$ C $低于C 的

在哪里我不得不更换字符串imageURI = NULL;什么电子邮件需要的图像。谢谢大家！

Where I have to replace "String imageURI = null;" with what the email needs as image. Thank you all!

编辑：

我设法修改我的code到这一点，即没有给出错误的：

I managed to edit my code to this, that gives no errors:

public void sendMail(ImageView image){
    Intent i = new Intent(Intent.ACTION_SEND);
    int imageURI = R.drawable.img1;

    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"[e-mail]"});
    i.putExtra(Intent.EXTRA_SUBJECT, "Oggetto");
    i.putExtra(Intent.EXTRA_TEXT   , "Globelife");
    i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    i.setType("image/jpeg");
    i.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://"+getPackageName()+"/"+imageURI));


    try {
        startActivity(Intent.createChooser(i, "Send mail..."));
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(Test01Activity.this, "Non sono presenti app per l'invio di e-mails.", Toast.LENGTH_SHORT).show();
    }

}

不过，我需要改变诠释imageURI = R.drawable.img1;为int imageURI = ImageView.src;或者类似的东西。

But I need to change "int imageURI = R.drawable.img1;" to "int imageURI = ImageView.src;" or something like that

推荐答案

试试这个

ImageView iv = (ImageView) findViewById(R.id.splashImageView);
Drawable d =iv.getBackground();
BitmapDrawable bitDw = ((BitmapDrawable) d);
Bitmap bitmap = bitDw.getBitmap();
File  mFile = savebitmap(bitmap);

然后

   Uri u = null;
   u = Uri.fromFile(mFile);

   Intent emailIntent = new Intent(Intent.ACTION_SEND);
   emailIntent.setType("image/*");
   emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Hello...");
   // + "\n\r" + "\n\r" +
   // feed.get(Selectedposition).DETAIL_OBJECT.IMG_URL
   emailIntent.putExtra(Intent.EXTRA_TEXT, "Your tsxt here");
   emailIntent.putExtra(Intent.EXTRA_STREAM, u);
   startActivity(Intent.createChooser(emailIntent, "Send email..."));

和 savebitmap 方法

    private File savebitmap(Bitmap bmp) {
  String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
  OutputStream outStream = null;
  File file = new File(extStorageDirectory, temp + ".png");
  if (file.exists()) {
   file.delete();
   file = new File(extStorageDirectory, temp + ".png");
  }

  try {
   outStream = new FileOutputStream(file);
   bmp.compress(Bitmap.CompressFormat.PNG, 100, outStream);
   outStream.flush();
   outStream.close();
  } catch (Exception e) {
   e.printStackTrace();
   return null;
  }
  return file;
 }
