我正在使用FragmentPagerAdapter三个选项卡。每个选项卡都有多个fragments，在这些片段之一中，我请求从图库或相机中获取照片。问题是托管选项卡onActivityResult()的父级Activity被调用而不是Fragment. 帮助赞赏。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case MEDIA_TYPE_IMAGE_FROM_GALLERY:
if (resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
String realPath = getImageRealPath(selectedImage);
realPaths.add(realPath);
Glide.with(mActivity)
.load(realPath)
.into(profile_imv);
}
break;
case MEDIA_TYPE_IMAGE_BY_CAMERA:
if (resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
String realPath = getImageRealPath(selectedImage);
realPaths.add(realPath);
Glide.with(mActivity)
.load(realPath)
.into(profile_imv);
}
break;
}
}
这是我如何称呼画廊和相机的意图
public void choosePhotoFromGallary() {
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, MEDIA_TYPE_IMAGE_FROM_GALLERY);
}
private void takePhotoFromCamera() {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(mActivity.getPackageManager()) != null) {
startActivityForResult(intent, MEDIA_TYPE_IMAGE_BY_CAMERA);
}
}
这是MainACtivity onActivityResult()代码
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment fragment = getSupportFragmentManager().findFragmentByTag("USER_DETAILS");
if (fragment != null) {
fragment.onActivityResult(requestCode, resultCode, data);
}
}
