Android 应用拍摄/电子邮件照片

Question

我目前正在编写一个应用程序，在某个活动中，我们希望用户能够拍摄照片并将其通过电子邮件发送到所需的电子邮件地址。我可以分别做这两项（拍照和发送照片），但是当我一起运行它们时，电子邮件客户端列表出现在相机上......我似乎无法弄清楚为什么它没有运行在相机本身之后..有什么帮助吗？

***这是我现在拥有的：

public class PhotoHandler extends Activity {

private final static int TAKE_PHOTO_CODE = 1;
File downloadedPic = null;
Intent in;

@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.mnwv_main);

  downloadedPic = takeandReturn(this);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{

  try {            
      Intent picMessageIntent = new Intent(android.content.Intent.ACTION_SEND);            
      picMessageIntent.setType("image/jpeg");
      picMessageIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(downloadedPic));
        picMessageIntent.putExtra(Intent.EXTRA_EMAIL  , new String[]{});
      picMessageIntent.putExtra(Intent.EXTRA_SUBJECT, "MNWV - Check Out This Photo!");
        picMessageIntent.putExtra(Intent.EXTRA_TEXT   , "*** Please Describe the Photo Taken Below (Include Your Name, Location, etc.)... ***");
      startActivity(Intent.createChooser(picMessageIntent, "Send Picture Using: ")); 
  } catch (Exception e) {
      Log.e("TAG", "sendPictureMessage() failed to start activity.", e);
      Toast.makeText(this, "No handler", Toast.LENGTH_LONG).show();
  } 
}

您必须使用 startActivityForResult 来拍照。之后您必须使用 onActivityResult 发送电子邮件：

   @Override
   public void onActivityResult(int requestCode, int resultCode, Intent data)
   {
       // TODO: Test for requestCode and resultCode
       try {            
           Intent picMessageIntent = new Intent(android.content.Intent.ACTION_SEND);            
           picMessageIntent.setType("image/jpeg");
           picMessageIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(downloadedPic));
           startActivity(Intent.createChooser(picMessageIntent, "Send Picture Using: "));
       } catch (Exception e) {
           Log.e("TAG", "sendPictureMessage() failed to start activity.", e);
           Toast.makeText(this, "No handler", Toast.LENGTH_LONG).show();
       }
   }

希望它会有所帮助。
