如何修复 android 中调整捕获图像大小的位图
How to fix bitmap resizing the captured image in android
我的照片编辑器 Android 应用程序有一些问题。通过应用程序从 20MegaPixel (5184x3880) 相机捕获图像后，我通过 Bitmap 将图像大小调整为 15MegaPixel (4477 x 3351)，然后将图像保存在 Gallery/Photos 文件夹中 phone

所以当我捕获图像然后当用户被带到编辑应用程序时，它不会，它会在捕获图像后再次将我带回主页

你能告诉我哪里错了吗？
提前致谢
if (extras != null) {

Intent imageEditorIntent = new AdobeImageIntent.Builder(this).setData(imageUri).build();
startActivityForResult(imageEditorIntent, IMAGE_EDITOR_RESULT);
// below line of code is not possible. your trying to receive result over
//here.
// . but your finishing it before it receives result
finish();
}
use below method close activity once data received. Pass data with set result method and then close. so your activity will have edited data.
better solution - you dont need this intermediate activity.
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case IMAGE_EDITOR_RESULT:

Log.d(TAG, "editedImageUri: " + editedImageUri.toString());
Bundle extra = data.getExtras();
if (extra != null) {
boolean changed = extra.getBoolean(AdobeImageIntent.EXTRA_OUT_BITMAP_CHANGED);

if (changed) {
mEditedImageView.setImageURI(editedImageUri);
}

As guidance -- below code is very bad practise in android
public static Intent getIntent(Context context, Bundle bundle) {
Intent intent = new Intent(context, MainActivity.class);
if (bundle != null) {
intent.putExtras(bundle);
}
return intent;
}
Good practise.
