[英]Portrait Camera Images when Uploaded via Library rotates in ImageView Android
在我的Android應用程序中,我有一個選項,用戶可以在注冊時拍照或從圖庫中上傳圖像。 該圖像一旦被相機成功拍攝或從圖庫中選擇,就會顯示在ImageView中。 下面是啟動該過程的ImageView代碼的onClick。
這來自活動布局。
<ImageView
android:id="@+id/imgUserImage"
android:layout_width="150dp"
android:layout_height="150dp"
android:scaleType="centerCrop"
android:onClick="changePicture"
app:srcCompat="@drawable/profile_image_not_provided"
android:layout_below="@+id/textView2"
android:layout_alignParentEnd="true"
android:layout_marginTop="10dp" />
這是來自Activity.java
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView imgProfilePicture = (ImageView)findViewById(R.id.imgUserImage);
int exif_orn_a;
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bitmap mphoto = (Bitmap) data.getExtras().get("data");
Uri selectedImage = data.getData();
imgProfilePicture.setImageURI(selectedImage);
imgProfilePicture.setImageBitmap(mphoto);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
mphoto.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bitmap is required image which have to send in Bitmap form
byte[] byteArray = baos.toByteArray();
encodedImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
}
else if (requestCode == PICK_IMAGE_GALLERY) {
Uri selectedImage = data.getData();
String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
Bitmap lphoto = null;
Cursor cur = this.getContentResolver().query(selectedImage, orientationColumn, null, null, null);
int orientation = -1;
if (cur != null && cur.moveToFirst()) {
orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
Toast.makeText(Register.this, "Picture Orientation "+orientation, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(Register.this, "Wrong Orientation", Toast.LENGTH_LONG).show();
}
if (cur != null) cur.close();
try {
lphoto = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
imgProfilePicture.setImageURI(selectedImage);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
lphoto.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bitmap is required image which have to send in Bitmap form
byte[] byteArray = baos.toByteArray();
encodedImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
} catch (IOException e) {
e.printStackTrace();
}
}
}
我設法正確地適應了方向。 現在的問題是,如何在imgProfilePicture.setImageURI(selectedImage);
之前旋轉圖像imgProfilePicture.setImageURI(selectedImage);
。
我設法找到了解決方案。 如果您認為這是即興的,請隨時發布更好的解決方案。
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView imgProfilePicture = (ImageView)findViewById(R.id.imgUserImage);
int exif_orn_a;
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bitmap mphoto = (Bitmap) data.getExtras().get("data");
Uri selectedImage = data.getData();
imgProfilePicture.setImageURI(selectedImage);
imgProfilePicture.setImageBitmap(mphoto);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
mphoto.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bitmap is required image which have to send in Bitmap form
byte[] byteArray = baos.toByteArray();
encodedImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
}
else if (requestCode == PICK_IMAGE_GALLERY) {
Uri selectedImage = data.getData();
//Starting from here, I am checking the Orientation and storing the result in orientation variable.
String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
Bitmap lphoto = null;
Cursor cur = this.getContentResolver().query(selectedImage, orientationColumn, null, null, null);
int orientation = -1;
if (cur != null && cur.moveToFirst()) {
orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
Toast.makeText(Register.this, "Picture Orientation "+orientation, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(Register.this, "Wrong Orientation", Toast.LENGTH_LONG).show();
}
if (cur != null) cur.close();
//This is the end of Orientation Check.
try {
lphoto = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
imgProfilePicture.setImageURI(selectedImage);
//Based on the Orientation Check result, I rotate the ImageView Image to make it straight.
if (orientation == 270) {
imgProfilePicture.setRotation(-90);
} else if (orientation == 0) {
imgProfilePicture.setRotation(0);
}
//This is the end of Image Rotation based on the Orientation Check Result.
ByteArrayOutputStream baos = new ByteArrayOutputStream();
lphoto.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bitmap is required image which have to send in Bitmap form
byte[] byteArray = baos.toByteArray();
encodedImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
} catch (IOException e) {
e.printStackTrace();
}
}
