[英]requestCode = -1 and resultCode = 0 chooserIntent for image from gallery or camera
So I managed to create a chooserIntent copying and pasting from this link the bounty-awarded answer. 因此,我设法通过这个链接创建了一个ChooserIntent 复制和粘贴 赏金奖的答案。 The problem I am facing is in the
onActivityResult
method. 我面临的问题是在
onActivityResult
方法中。 The requestCode that I receive is -1 and the resultCode is 0. What is wrong with the code? 我收到的requestCode为-1,resultCode为0。代码有什么问题?
Starting intent: 开始意图:
private void openImageIntent() {
// Determine Uri of camera image to save.
final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
root.mkdirs();
final String fname = "img_" + System.currentTimeMillis() + ".jpg";
final File sdImageMainDirectory = new File(root, fname);
outputFileUri = Uri.fromFile(sdImageMainDirectory);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));
startActivityForResult(chooserIntent, 0);
}
The onActivityResult
: onActivityResult
:
@Override
protected void onActivityResult(int resultCode, int requestCode, Intent returnIntent) {
super.onActivityResult(resultCode, requestCode, returnIntent);
if(requestCode == 0) {
if(resultCode == RESULT_OK) {
final boolean isCamera;
if(returnIntent == null)
{
isCamera = true;
}
else
{
final String action = returnIntent.getAction();
if(action == null)
{
isCamera = false;
}
else
{
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
Uri selectedImageUri;
if(isCamera)
{
selectedImageUri = outputFileUri;
ivProfilePicture.setImageURI(selectedImageUri);
makeToast(selectedImageUri.toString(), false);
}
else
{
selectedImageUri = returnIntent == null ? null : returnIntent.getData();
makeToast(selectedImageUri.toString(), false);
}
}
}
}
RESULT_OK=-1
per the Activity definition. 根据活动定义,
RESULT_OK=-1
。 You specified the request code as 0, so that also looks fine. 您将请求代码指定为0,因此看起来也不错。 Your problem: You are mixing up the requestCode and resultCode, as is specified for the Activity class .. Try this:
您的问题:您要混合使用Activity类指定的requestCode和resultCode。
protected void onActivityResult(int requestCode, int resultCode, Intent returnIntent) 受保护的void onActivityResult(int requestCode,int resultCode,Intent returnIntent)
