我创建了一个具有此主题的活动
Theme.AppCompat.Dialog
使用主题会导致一些问题,如果主题效果不好。
问题是在Java类中我启动了一个请求但是第二个的意图没有启动
private void setupProfileImage() {
startActivityForResult(getPickImageChooserIntent(this), PICTURE_INTENT);
}
捕获结果
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && requestCode == PICTURE_INTENT) {
Uri imageUri = getPickImageResultUri(data, this);
// For API >= 23 we need to check specifically that we have permissions to read external storage,
// but we don't know if we need to for the URI so the simplest is to try open the stream and see if we get error.
boolean requirePermissions = false;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
isUriRequiresPermissions(imageUri, this)) {
// request permissions and handle the result in onRequestPermissionsResult()
requirePermissions = true;
mImageUri = imageUri;
requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0);
}
if (!requirePermissions) {
startCropImageActivity(imageUri);
}
}
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
Uri resultUri = result.getUri();
Picasso.with(this).load(resultUri).fit().centerCrop().into(profilePicture);
profileChosen = true;
mImageUri = resultUri;
}
}
}
第二意图
private void startCropImageActivity(Uri imageUri) {
if (imageUri == null){
return;
}
CropImage.activity(imageUri)
.setAspectRatio(1,1)
.setFixAspectRatio(true)
.setGuidelines(CropImageView.Guidelines.ON)
.setAutoZoomEnabled(true)
.setCropShape(CropImageView.CropShape.OVAL)
.start(this);
}
注意:当我从活动中删除主题时,它的工作非常精细
我真的想要一个对话而不是整页活动!
