这是我调整图像大小的方法： -
if (resultCode == Activity.RESULT_OK) {
if (requestCode == GALLERY_ACTIVITY_CODE) {
Parcelable[] parcelableUris = intent.getParcelableArrayExtra(ImagePickerActivity.EXTRA_IMAGE_URIS);
if (parcelableUris == null) {
Utility.showNotifyMessage(getActivity(), "Please Select an Image");
} else {
// Java doesn't allow array casting, this is a little hack
Uri[] uris = new Uri[parcelableUris.length];
System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);
Uri newImageUploadUrl = Uri.EMPTY;
if (uris != null) {
for (Uri uri : uris) {
Log.i(TAG, " uri: " + uri);
newImageUploadUrl = uri;
}
if (String.valueOf(newImageUploadUrl).equalsIgnoreCase("")) {
Utility.showNotifyMessage(getActivity(), "Please Select any Image");
} else {
long freeSize = 0L;
long totalSize = 0L;
long usedSize = -1L;
try {
Runtime info = Runtime.getRuntime();
freeSize = info.freeMemory();
totalSize = info.totalMemory();
usedSize = totalSize - freeSize;
} catch (Exception e) {
e.printStackTrace();
}
// Log.e("totalSize "+totalSize,"freeSize "+freeSize+"usedSize "+usedSize);
Bitmap selectedBitmap = null;
try {

options.inPreferredConfig = Bitmap.Config.ARGB_8888;

} catch (OutOfMemoryError e) {
Log.e("Nithin 0", "" + e.toString());
Toast.makeText(getContext(), "Out of Memory,Please free your phone memory", Toast.LENGTH_SHORT).show();
}
if (selectedBitmap != null) {
if (ImageClicked.equalsIgnoreCase("1")) {
try {
usrimage1.setImageBitmap(Bitmap.createScaledBitmap(selectedBitmap, usrimage1.getWidth(), usrimage1.getHeight(), false));
usrimage1.setScaleType(ImageView.ScaleType.FIT_XY);
IsProfilePic = 1;
if (usrimage1.getTag() != new Integer(0))
DeleteImageID = (String) usrimage1.getTag().toString();
} catch (OutOfMemoryError e) {
Log.e("Nithin 1", "" + e.toString());
}
} else if (ImageClicked.equalsIgnoreCase("2")) {
try {
IsProfilePic = 2;
usrimage2.setImageBitmap(Bitmap.createScaledBitmap(selectedBitmap, usrimage2.getWidth(), usrimage2.getHeight(), false));
usrimage2.setScaleType(ImageView.ScaleType.FIT_XY);

}
} else if (ImageClicked.equalsIgnoreCase("3")) {

usrimage3.setImageBitmap(Bitmap.createScaledBitmap(selectedBitmap, usrimage3.getWidth(), usrimage3.getHeight(), false));
usrimage3.setScaleType(ImageView.ScaleType.FIT_XY);
if (usrimage3.getTag() != new Integer(0))
DeleteImageID = usrimage3.getTag().toString();
} catch (OutOfMemoryError e) {
Log.e("Nithin 3", "" + e.toString());
}
} else if (ImageClicked.equalsIgnoreCase("4")) {
try {
IsProfilePic = 4;
usrimage4.setImageBitmap(Bitmap.createScaledBitmap(selectedBitmap, usrimage4.getWidth(), usrimage4.getHeight(), false));
usrimage4.setScaleType(ImageView.ScaleType.FIT_XY);

}
}
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
selectedBitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
encoded = resizeBase64Image(Base64.encodeToString(byteArray, Base64.DEFAULT));
public String resizeBase64Image(String base64image) {
byte[] encodeByte = Base64.decode(base64image.getBytes(), Base64.DEFAULT);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPurgeable = true;
Bitmap image = BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length, options);
if (image.getHeight() <= 400 && image.getWidth() <= 400) {
return base64image;
}
image = Bitmap.createScaledBitmap(image, 400, 400, false);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
System.gc();
return Base64.encodeToString(b, Base64.NO_WRAP);
}
这是我的json解析代码，我希望参数AboutMe作为base 64类型。但它调整了image.i想要完整大小的图像。

RequestQueue profilePicQueue = Volley.newRequestQueue(getActivity());
profilePicQueue.add(profilePicRequest);

我的问题是我想要获得完整宽度和高度的图像。我不知道相机和位图。任何人都可以告诉我该怎么做？
