try {
PlacePicker.IntentBuilder intentBuilder = new PlacePicker.IntentBuilder();
intentBuilder.setLatLngBounds(BOUNDS_MOUNTAIN_VIEW);
Intent intent = intentBuilder.build(MainActivity.this);
startActivityForResult(intent, 1);
} catch (Exception e) {
e.getMessage();
}
}
});
#Override

android app implement google auto complete activity for 2 inputs

I have 2 edit text inputs in my app.One is from place and another one to place.For these 2 inputs I have implemented google auto complete activity but problem when user click on any one of these inputs google autocomplete intent after user place selection completed intent call onActivityResult().
In onActivityResult() how to know which input clicked.
here is my code
fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
.build();
Intent intent =
new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
.build(MainActivity.this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
.build();
Intent intent =
new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
.build(MainActivity.this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = PlaceAutocomplete.getPlace(this, data);
String fullName= (String) place.getAddress();
#// here I want to know which input clicked and set fullname in input text#
fromPlaceEdit.setText(fullName);
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(this, data);
// TODO: Handle the error.
Log.i("fdfdf", status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
}
}

I did it different way.
I have created two global boolean value each for from place and to place.
then when user click on from place or to place change boolean value of same place then on onActivityResult check which boolean value is true and set result place name to same input box.
Code follows:
public boolean fromplaceSlected =false ;
public boolean toplaceSlected =false;
fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
.build();
Intent intent =
new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
.build(MainActivity.this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
.build();
Intent intent =
new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
.build(MainActivity.this);
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.e("request", String.valueOf(requestCode));
// Check that the result was from the autocomplete widget.
if (requestCode == REQUEST_CODE_AUTOCOMPLETE) {
if (resultCode == RESULT_OK) {
// Get the user's selected place from the Intent.
Place place = PlaceAutocomplete.getPlace(getContext(), data);
String fullName = (String) place.getAddress();
if(fromplaceSlected){
Log.e("from place",fullName);
fromPlaceEdit.setText(fullName);
fromplaceSlected=false;
toplaceSlected=false;
}
else if(toplaceSlected){
Log.e("toplace" ,fullName);
toPlaceEdit.setText(fullName);
fromplaceSlected=false;
toplaceSlected=false;
}
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(getContext(), data);
Log.e("sdsdsdd", "Error: Status = " + status.toString());
fromplaceSlected=false;
toplaceSlected=false;
} else if (resultCode == RESULT_CANCELED) {
// Indicates that the activity closed before a selection was made. For example if
// the user pressed the back button.
fromplaceSlected=false;
toplaceSlected=false;
}
}
}

Your code may work, but it's a bit hacky. Here is the good way to do it:
public static final int PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE=1;
public static final int PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE=2;
fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
//Do your stuff from place
startActivityForResult(intent, PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
//Do your stuff to place
startActivityForResult(intent, PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE);
} catch (GooglePlayServicesRepairableException e) {
// TODO: Handle the error.
} catch (GooglePlayServicesNotAvailableException e) {
// TODO: Handle the error.
}
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
//Do your ok >from place< stuff here
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
//Handle your error >from place<
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
} else if (requestCode == PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
//Do your ok >to place< stuff here
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
//Handle your error >to place<
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
}
}
From documentation:
requestCode int: If >= 0, this code will be returned in onActivityResult() when the activity exits.

Parse FB Login Crash on Function Not Included in Login

I have integrated Parse Login (v1.10.3) and never had this issue until I integrated FB Login (v4.8.2). If uninstall and re-install the app and launch, when the app launches I receive an error from an activity that occurs after Login. I have the MainActivity as the launch page and it checks for a current user. If the current user is null it redirects to the LoginActivity. The LoginActivity crashes with a Null Pointer Exception error that occurs in an Adapter linked to a Fragment called from the Main Adapter. Why is my Login Activity being skipped?
I have a lot of logs in my code as I was trying to determine if there is a current user value at some point or if there is any Login function executed that would cause it to skip the Login, but none of it is executed and the current user is always Null (which I expect).

How to set an image on imageView from the gallery and image taken by camera in Android?

In my app I want to set an image on a ImageView from gallery and I want to set an image which is taken by the camera. I have tried this code, when I load image from the gallery, it is working. But when I try to take a picture to set on ImageView, that activity is loaded but the image is not showing in the ImageView. Any solution for this? Here is my code:
First Activity
public class MainActivity extends ActionBarActivity {

Take a look at the selected as best answer here Take photo w/ camera intent and display in imageView or textView? and you could find out how to take a picture and set it as a background of an imageView programmatically

zxing barcode scanner results in null

I followed guide from this page and I get the intent fired up. It also found barcode. However when
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanResult != null) {
showMessage("result", scanResult.toString());
}
// else continue with any other code you need in the method
}
is reached the dialog(showMessage function basically just creates dialog with title and text) shows following text:
Format: null
Contents: null
Raw bytes: (0bytes)
Orientation: null
EC level: null
Have I missed some part or is it just issue with bar codes? I have tried every product with barcode that I have lying around but no change.

My project used to do something like that:
public class MenuScreen extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu_screen);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_menu_screen, menu);
return true;
}
public void onScanCodeClick(View view) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage("com.google.zxing.client.android");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
try {
startActivityForResult(intent, 0);
} catch (ActivityNotFoundException aex) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("No Application Found");
builder.setMessage("We could not find an application to scan QR CODES."
+ " Would you like to download one from Android Market?");
builder.setPositiveButton("Yes, Please",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent marketIntent = new Intent(Intent.ACTION_VIEW);
marketIntent.setData(Uri
.parse("market://details?id=com.google.zxing.client.android"));
startActivity(marketIntent);
}
});
builder.setNegativeButton("No, Thanks", null);
builder.create().show();
}
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
Intent intent2 = new Intent();
intent2.setClass(this, MenuCodeSuccess.class);
intent2.putExtra("qrDetails", contents);
startActivity(intent2);
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
}
}
}
}
onScanCodeClick is just an onClickListener for button. You can of course init your button and use this code instead.
And here is an xml layout:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnCount="2" >
<Button
android:id="#+id/menuScreen_SCANCODE"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onScanCodeClick"
android:text="#string/scanButton" />
</TableLayout>
Please don't care the style of layout, all what you need is just in java class. :) but it should be working anyway.

// In side onActivityResult(), try this code
if (resultCode == IntentIntegrator.REQUEST_CODE) {
Log.e("inside Request code~~~~~~~~>", "Barcode>>>>");
IntentResult scanResult = IntentIntegrator.parseActivityResult(
requestCode, resultCode, data);
if (scanResult == null) {
Log.e("Scan Result~~~~~~~~>", "value>>> Null");
return;
}
final String result = scanResult.getContents();
final String result1 = scanResult.getFormatName();
if (result != null) {
handlerBarcode.post(new Runnable() {
#Override
public void run() {
// txtScanResult.setText(result);
// txtScanResultFormat.setText(result1);
Toast.makeText(Activity_Form_Data_4.this,
"Code:" + result + " Format:" + result1,
Toast.LENGTH_SHORT).show();
}
});
}
}
