通過Android應用程序將圖像附加到電子郵件

Question

我的應用成功制作了電子郵件，但當我嘗試附加圖片時，代碼崩潰就是代碼片段

        Intent i = new Intent(Intent.ACTION_SEND);
        i.setType("message/rfc822");
        i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"email address"});
        i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
        i.putExtra(Intent.EXTRA_TEXT   , "body of email");
    //  i.putExtra(Intent.EXTRA_STREAM, R.drawable.pic4);



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

評論的行使代碼崩潰請建議出路！

Answer 1

這對你不起作用：

i.putExtra(Intent.EXTRA_STREAM, R.drawable.pic4);

R.drawable.pic4的類型是什么？ 這不是用於解析drawable的整數嗎？

了解其他人如何附加圖片： 使用Intent.ACTION_SEND和Intent.EXTRA_STREAM與Google+應用分享圖片

Answer 2

這很簡單：P

Intent i = new Intent(Intent.ACTION_SEND);

        int imageURI=R.drawable.pic4;

        i.setType("message/rfc822");
        i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"email address"});
        i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
        i.putExtra(Intent.EXTRA_TEXT   , "body of email");
        i.putExtra(Intent.EXTRA_STREAM, R.drawable.pic4);

            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(EidCards.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
        }
