我正在尝试通过嵌入数据的 html 以电子邮件正文的内联形式发送图像。html 显示正确,但图像现在显示在图像的位置,我看到一个写有“obj”的小块。我还将位图img转换为base64形式。代码如下:
public void imageRetrieved(byte[] img)
{
Bitmap newImg=BitmapFactory.decodeByteArray(img,0,img.length);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
newImg.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
String imageEncoded = Base64.encodeToString(b,Base64.DEFAULT);
Log.d("LOOK", imageEncoded);
String txtBody = "<html><body><h1>hi it is stoneage product</h1><br><img src ='data:image/jpeg;base64,"+imageEncoded+"'/></body></html>";
Log.d("data", txtBody);
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/html");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "testemail");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(txtBody));
startActivity(Intent.createChooser(emailIntent, "Email:"));
}
请帮帮我
最佳答案
试试这个,它对我有用
File pngDir = new File(Environment.getExternalStorageDirectory(),"saved_images/");
if (!pngDir.exists())
{
pngDir.mkdirs();
}
File pngfile=new File(pngDir,"stoneage.jpg");
Uri pngUri =Uri.fromFile(pngfile);
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{""});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "hi it is stoneage product Hi this is test mail with attachment");
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM,pngUri);
emailIntent.setType("message/rfc822");
startActivity(Intent.createChooser(emailIntent, "Email:"));
