I try to select contact from contacts list:
contactsButton.Click += (object sender, EventArgs e) =>
{
//Create a new intent for choosing a contact
var contactPickerIntent = new Intent(Intent.ActionPick, Android.Provider.ContactsContract.Contacts.ContentUri);
//Start the contact picker expecting a result
// with the resultCode '101'
StartActivityForResult(contactPickerIntent, 101);
};
and method OnActivityResult called under xamarin debugger and not called on my real device (SGS4).
When user cancels operation in contacts list, method OnActivityResults called under debugger and on real device.
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
phoneNumberText.Text = String.Format("request={0}, result={1}", requestCode, resultCode);
base.OnActivityResult(requestCode, resultCode, data);
...
}
update:
I don't understand why, but next line solves the issue: contactPickerIntent.SetType(ContactsContract.CommonDataKinds.Phone.ContentType);
contactsButton.Click += (object sender, EventArgs e) =>
{
//Create a new intent for choosing a contact
var contactPickerIntent = new Intent(Intent.ActionPick, Android.Provider.ContactsContract.Contacts.ContentUri);
contactPickerIntent.SetType(ContactsContract.CommonDataKinds.Phone.ContentType);//(Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers
//Start the contact picker expecting a result
// with the resultCode '101'
StartActivityForResult(contactPickerIntent, 101);
};
line contactPickerIntent.SetType(...) somehow fixes the issue.
contactsButton.Click += (object sender, EventArgs e) =>
{
//Create a new intent for choosing a contact
var contactPickerIntent = new Intent(Intent.ActionPick, Android.Provider.ContactsContract.Contacts.ContentUri);
contactPickerIntent.SetType(ContactsContract.CommonDataKinds.Phone.ContentType);//(Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers
//Start the contact picker expecting a result
// with the resultCode '101'
StartActivityForResult(contactPickerIntent, 101);
};
I have never used xamarin but in terms of Android dev try changing the code onActivityResult code to:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
....
}

I searched a lot and tried things but the onActivityResult function isn't launched when the intent from which I try to get a string information is closed.
I use Visual Studio to write this application, this is my code :
The click event that opens the activity where users can type strings :
private void Btn_Valid_Click(object sender, EventArgs e)
{
----
Intent intent = new Intent(this, typeof(activity_OF_TransfertChxChmb));
StartActivityForResult(intent, 0);
----
}
The function in the openned Intent that should return the string information :
private void Validate()
{
string stringToPassBack = tb_Store.Text;
// put the String to pass back into an Intent and close this activity
Intent intent = new Intent();
intent.PutExtra("result", stringToPassBack);
SetResult(Result.Ok, intent);
Finish();
}
And the onActivityResult function that should be launched in the first activity:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
base.onActivityResult(requestCode, 0, data);
if (requestCode == 0)
{
if (resultCode == -1) // Ok
{
string result = data.GetStringExtra("result");
}
if (resultCode == 0) // Canceled
{
//Write your code if there's no result
}
}
}
I am missing something, but can't figure out what.
Thank you for your help.
You are adding the extra via:
intent.PutExtra(Intent.ExtraText, stringToPassBack);
Your key is Intent.ExtraText.
You are retrieving the extra via:
string result = data.GetStringExtra("result");
Your key is "result".
So, perhaps Intent.ExtraText does not equal "result". You need to use the same key in both places.
I have the following code
public void changeContentOnClick(View view) {
Intent intent = new Intent(this, ChangeNodeContentActivity.class);
intent.putExtra("SELECTED_NODE_ID", selectedNode.getNodeId());
intent.putExtra("SELECTED_NODE_CONTENT", selectedNode.getNodeContent());
startActivityForResult(intent,RESULT_OK);
Log.d(TAG, "Can I get here?");
onActivityResult(RESULT_OK, RESULT_OK, intent);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
String editedNodeId = data.getStringExtra("EDITED_NODE_ID");
String editedNodeContent = data.getStringExtra("EDITED_NODE_CONTENT");
Node nodeChecker = new Node(editedNodeId);
Node editedNode = new Node(editedNodeId, editedNodeContent);
Log.d(TAG, editedNode.toString());
nodes.set(nodes.indexOf(nodeChecker), editedNode);
adapter.notifyDataSetChanged();
}
} catch (Exception e) {
Toast.makeText(this, e.toString(), Toast.LENGTH_SHORT).show();
}
}
Somehow, after startActivityForResult method is called, everything stops. The log with message "Can I get here?" is never printed and I don't understand why not. I have followed the answer to this topic, but somehow couldn't make it work. Do I call the onActivityResult in the wrong way or place? Please help me out!
The that should send back some info from the ChangeNodeContentActivity and the one that handles the result code is the following on click listener:
public void changeContentOnClick(View view) {
Intent intent = getIntent();
selectedNode.setNodeContent(nodeContentDisplay.getText().toString());
intent.putExtra("EDITED_NODE_ID", selectedNode.getNodeId());
intent.putExtra("EDITED_NODE_CONTENT", selectedNode.getNodeContent());
setResult(RESULT_OK, intent);
Log.d(TAG, selectedNode.toString());
finish();
}
startActivityForResult() method receives an intent and requestCode, so you should change it to:
startActivityForResult(intent, REQUEST_CODE)
And onActivityResult() method is automatically called when returning from the activity, so you should remove the direct call you made to the method, i.e. onActivityResult(RESULT_OK, RESULT_OK, intent)
my code :
public void run() {
while (!done){
try {
this.mListMessagesResponse = service.users().messages().list(userId).setQ("to:" + recipient).execute().getMessages();
done = true;
} catch(UserRecoverableAuthIOException e) {
mActivity.startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
//wait result
} catch (IOException e) {
e.printStackTrace();
}
}
}
i want wait the result from my user to start again my loop.
i tried with wait but it doesn't work.
You don't need a while loop to get the result from an Activity. There is already a build-in function to do that. It's onActivityResult
From the docs:
Start the Activity
static final int PICK_CONTACT_REQUEST = 1; // The request code
...
private void pickContact() {
Intent pickContactIntent = new Intent(Intent.ACTION_PICK, Uri.parse("content://contacts"));
pickContactIntent.setType(Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers
startActivityForResult(pickContactIntent, PICK_CONTACT_REQUEST);
}
Use onActivityResult to get the result.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == PICK_CONTACT_REQUEST) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
// The user picked a contact.
// The Intent's data Uri identifies which contact was selected.
// Do something with the contact here (bigger example below)
}
}
}

I call an intent now how can i get result from called activity
can any one tell me how to perform this task ?
i have called intent like.
Intent I = new Intent (this ,abc.class);
startActivity(i);
thanks
Use startActivityForResult and then override onActivityResult in your FirstActivity.
In FirstActivity
Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
startActivityForResult(intent, 2);// Activity is started with requestCode 2
Override onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
// check if the request code is same as what is passed here it is 2
if(requestCode==2)
{
String message=data.getStringExtra("MESSAGE");
Log.i("Message is",message);
// logs Testing
}
}
In SecondAcivity
Intent intent=new Intent();
intent.putExtra("MESSAGE","Testing");
setResult(2,intent);
finish();//finishing activity
Reference to the docs:
http://developer.android.com/reference/android/app/Activity.html#startActivityForResult(android.content.Intent, int)
Example:
http://www.javatpoint.com/android-startactivityforresult-example
For going to second activity use startActivityForResult in your firstclass
Intent callIntent = new Intent(FirstClass.this, SecondClass.class);
startActivityForResult(callIntent, 1);
then override onActivityResult method in your first class like this
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == 1) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
// get values from data
}
} }
In your second class do this for returning back, if you want to send
something to first class. Store this in your intent.
Intent result = new Intent(); setResult(Activity.RESULT_OK, result);
finish();
hi you can get result calling activity
Start activity with startActivityForResult(intent, 0);
add below method in calling activity
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
// do your task
} else if (resultCode == RESULT_CANCELED) {
// do your task
}
}
}
In your main Class....
static final int CODE_REQUEST = 1; // The request code
....
Intent pickContactIntent = new Intent(MainClass.this, CallingClassName.class);
startActivityForResult(pickContactIntent, CODE_REQUEST);
..........
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == PICK_CONTACT_REQUEST) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
// The user picked a contact.
// The Intent's data Uri identifies which contact was selected.
// Do something with the contact here (bigger example below)
}
}
}
In your calling class
Intent result = new Intent();
setResult(Activity.RESULT_OK, result);
finish()
In my application I have scan button which scan qr code. Code is like this:
btnScan.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 1);
ClearForm();
//if (!CheckCHFID())return;
pd = ProgressDialog.show(EnquireActivity.this, "", getResources().getString(R.string.GetingInsuuree));
new Thread(){
public void run(){
getInsureeInfo();
pd.dismiss();
}
}.start();
}
});
Now the problem is before I scan the code it starts finding the information which is getInsureeInfo(); How can I control that it should execute only after user scans the code successfully?
Thanks in advance.
you need to move the part that you want to happen after the scan to the onActivityResult() method.
/*Here is where we come back after the Barcode Scanner is done*/
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
// contents contains whatever the code was
String contents = intent.getStringExtra("SCAN_RESULT");
// Format contains the type of code i.e. UPC, EAN, QRCode etc...
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan.
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel. If the user presses 'back' before a code is scanned.
}
}
}
Also I think you are going to have to use a Handler to send a message from the work thread to the main thread when it is time to hide your progress dialog. I don't think it will let you call dismiss on it from the background thread. That is just a hunch though, not tested.
put it in OnActivityResult method ,ovveride it.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case 1:
if (resultCode == RESULT_OK) {
//put your stuff here....
break;
}
}
}
