Question

我目前正在编写一个应用程序，在某项活动中，我们希望用户能够将照片和电子邮件发送到所需的电子邮件地址。我能够分别做这两件事（拍照和发照片），但是当我一起运行时，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..有任何帮助吗？

***这就是我现在所拥有的：

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拍摄照片。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。
