我已经能够使用相机拍摄照片或从画廊中取出并使用此代码在ImageView中显示它.我现在需要做的是使用该图片并将其上传到Parse.我一直在谷歌上搜索,我没有找到正确的方法来做到这一点.有人可以帮我这个吗？是否可以从ImageView上传图像？谢谢.
protected Button mFromCamera;protected Button mFromGallery;protected ImageView mImageView;private static final int CAMERA_REQUEST = 1888;private static final int SELECT_PHOTO = 100;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//Initialize ImageViewmImageView = (ImageView) findViewById(R.id.ImgPrev);//Initialize CameramFromCamera = (Button) findViewById(R.id.FromCamera);//use cameramFromCamera.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);startActivityForResult(cameraIntent,CAMERA_REQUEST);} //use camera end});//initialize buttonmFromGallery = (Button) findViewById(R.id.FromGallery);//pick a photomFromGallery.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View arg0) {Intent photoPickerIntent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);photoPickerIntent.setType("image/*");startActivityForResult(photoPickerIntent,SELECT_PHOTO);}});//pick a photo end}//previewing Image@Overrideprotected void onActivityResult(int requestCode,int resultCode,Intent data) {super.onActivityResult(requestCode,resultCode,data);switch (requestCode) {//from the gallerycase SELECT_PHOTO:if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK && null!= data) {Uri selectedImage = data.getData();String[] filePathColumn = { MediaStore.Images.Media.DATA };Cursor cursor = getContentResolver().query(selectedImage,filePathColumn,null,null);cursor.moveToFirst();int columnIndex = cursor.getColumnIndex(filePathColumn[0]);String picturePath = cursor.getString(columnIndex);cursor.close();mImageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));}break;//from the cameracase CAMERA_REQUEST:if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {Bitmap photo = (Bitmap) data.getExtras().get("data");mImageView.setImageBitmap(photo);}break;}}//Preview Image End
最佳答案
阅读你的答案：
I already followed the code that you have before. I was able to upload the image to parse. but I dont know how to switch the drawable source to be my image from camera/gallery or imageview. – stanley santoso

我明白你的问题不是解析你的形象？
试着回答你的问题：
I dont know how to switch the drawable source to be my image from camera/gallery or imageview.
1 – R.drawable.androidbegin似乎是你的问题但事实是你已经在你的代码中解析了你的位图：
来自画廊 – >
mImageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
来自相机 – >
Bitmap photo = (Bitmap) data.getExtras().get("data");
2 – 所以我建议在代码的开头声明一个Bitmap类型的变量
private Bitmap yourbitmap;
3 – 然后在代码中为库和相机分配位图,并使用它来解析它.
...yourbitmap = BitmapFactory.decodeFile(picturePath);...yourbitmap = (Bitmap) data.getExtras().get("data");...
4 – 最后你可以这样使用你的位图：
// Bitmap bitmap = BitmapFactory.decodeResource(getResources(),// R.drawable.androidbegin);// Convert it to byteByteArrayOutputStream stream = new ByteArrayOutputStream();// Compress image to lower quality scale 1 - 100yourbitmap.compress(Bitmap.CompressFormat.PNG,100,stream);byte[] image = stream.toByteArray();...
