Question

我尝试了很多来自stackoverflow和Internet的代码。但是我能够找到如何从相机中拾取图像。我使用了以下代码，但是data.getData（）始终返回null。不知道如何解决。帮助这个。

 Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
          startActivityForResult(cameraIntent, 30);
        protected void onActivityResult(int requestCode, int resultCode, Intent data)
                {  
                    if (requestCode == 30 && resultCode == Activity.RESULT_OK&&data!null)
                    {  
                  if(data.getData()!null){
                        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
                        imageView.setImageBitmap(photo);
}
                    }  
                }

尝试此代码@Thrishool，

private static final int CAMERA = 1;

//choosing the image from camera
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, CAMERA);



//now get the data from the onActivity result

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

    super.onActivityResult(requestCode, resultCode, data);

   if (requestCode == CAMERA) {
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        imageview.setImageBitmap(thumbnail);
        ByteArrayOutputStream baos=new  ByteArrayOutputStream();
        thumbnail.compress(Bitmap.CompressFormat.PNG,100, baos);
        byte [] b=baos.toByteArray();
        String temp = Base64.encodeToString(b, Base64.DEFAULT);
        Log.e("savedImage",temp);

        Toast.makeText(ProfileActivity.this, "Image Saved!", Toast.LENGTH_SHORT).show();
    }
}

尝试一下，让我知道@Thrishool
