i am using following codes.
addNewReceipt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(v.getContext(), AddReceipt.class);
myIntent.putExtra("receiptList", receipts);
startActivityForResult(myIntent, RECEIPT_ADD);
}
});
}
#SuppressWarnings("unchecked")
public synchronized void onActivityResult(final int requestCode, int resultCode, final Intent data)
{
if (resultCode == Activity.RESULT_OK)
{
if (requestCode == RECEIPT_ADD)
{
receipts = (ArrayList<Receipt>) data.getSerializableExtra("receiptList");
addReceiptsInListView();
}
}
}
The code for AddReceipt class is as follow,
#Override
public void finish() {
Intent data = new Intent();
data.putExtra("receiptList", receipts);
setResult(RESULT_OK, data);
super.finish();
}
#SuppressWarnings("unchecked")
public void onCreateCall()
{
done.setOnClickListener(new OnClickListener()
{ //receiptAddBtn
#Override
public void onClick(View v)
{
String error = "";
Receipt receipt = new Receipt();
receipt.comments = comments.getText().toString();
receipt.referenceNo = receiptNo.getText().toString();
receipt.image = imageSelected;
if (receipt.image == null || receipt.referenceNo == "" )
{
error = "Please input Receipt No. and attach Image";
displayAlert(error);
}
else
{
receipts.add(receiptCounter,receipt);
finish();
}
}
});
}
The problem is, when the activity is finished... and i pass this receipt, in my previous class from which i call this activity public synchronized void onActivityResult Never works.
The back button is not ending activity either.
Please tell me where i am wrong,.
Best Regards
Here is the solution to your problem
#Override
public void finish() {
Intent data = new Intent();
data.putExtra("receiptList", receipts);
setResult(Activity.RESULT_OK, data);
super.finish();
}

I tried using a "speech to text" feature in my app.
it opens up the recording window/ dialog or whatever but the text doesn't show.
this is the code:
public void onTalk(View v){
promptSpeechInput();
}
public void promptSpeechInput()
{
Intent i=new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
i.putExtra(RecognizerIntent.EXTRA_PROMPT,"say something");
try{
startActivityForResult(i, 50);
}
catch(ActivityNotFoundException e){
Toast.makeText(this,"sorry your device doesnt support speech language",Toast.LENGTH_LONG).show();
}
}
then there's the onResult part:
public void onActivityResult(int request_code, int result_code, Intent i){
super.onActivityResult(request_code,result_code,i);
if (request_code==RESULT_OK)
if(i!=null) {
EditText locationTS = (EditText) findViewById (R.id.locationET);
ArrayList<String> result = i.getStringArrayListExtra((RecognizerIntent.EXTRA_RESULTS));
locationTS.setText(result.get(0));
}
}
locationTS is an EditText, and it does not show any text after i talk.
This worked in my case:
I had a separate Helper class as:
public class SpeechRecognitionHelper {
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
public static void run(Activity activity){
if(isSpeechRecognitionActivityPresent(activity)){
startRecognition(activity);
}
else {
Toast.makeText(activity,"You must install Google Voice Search",Toast.LENGTH_LONG).show();
installGoogleVoiceSearch(activity);
}
}
private static boolean isSpeechRecognitionActivityPresent(Activity activity){
try {
PackageManager packageManager = activity.getPackageManager();
List activities = packageManager.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH),0);
if (activities.size()!=0){
return true;
}
}
catch (Exception e){
}
return false;
}
public static void startRecognition(Activity activity){
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,"Say Something");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1);
activity.startActivityForResult(intent,VOICE_RECOGNITION_REQUEST_CODE);
}
private static void installGoogleVoiceSearch(final Activity activity){
Dialog dialog = new AlertDialog.Builder(activity)
.setMessage("For recognition Install Google Voice Search")
.setTitle("Install voice search?")
.setPositiveButton("Install", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.voicesearch"));
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
activity.startActivity(intent);
}
})
.setNegativeButton("Cancel", null)
.create();
dialog.show();
}
}
Then in the MainActivity:
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
private static final int CAMERA_REQUEST=201;
private Button buttonVoiceCommand;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonVoiceCommand = (Button)findViewById(R.id.buttonVoiceCommand);
buttonVoiceCommand.setOnClickListener(this);
}
#Override
public void onClick(View view) {
int id = view.getId();
if (id == R.id.buttonVoiceCommand){
run(MainActivity.this);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if(matches.size()>0){
if(matches.get(0).indexOf("camera")>0){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,CAMERA_REQUEST);
}
else {
Toast.makeText(this,matches.get(0),Toast.LENGTH_LONG).show();
}
}
}
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Perform whatever you want to do (-.-)
Toast.makeText(this,"Camera Working",Toast.LENGTH_LONG).show();
}
}
}
I Toast the content of matches.get(0) You just have to set it in an edit text
i have two activities A and B i am using a button to be directed to activity B i managed to write a code so it code be turned back to activity A automatically without any buttons after 5 seconds
but now i want when it return back to return data to A how it can be done
i wrote the code in A to recieve data but don't know what to add in activity B
Activity A ::
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button two = (Button) findViewById(R.id.button2);
Recieve = (TextView) findViewById(R.id.textView4);
two.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Intent Intent = new Intent(MainActivity.this, Gps.class);
//startActivity( Intent);
sendMessage();
}
});
}
public void sendMessage() {
Intent intent = new Intent(MainActivity.this, Hello.class);
startActivityForResult(intent, REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
Response = data.getStringExtra("key");
Recieve.setText("msg is " + Response);
}
}
Activity B::
public class Hello extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hello);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
final Intent i = new Intent(Hello.this, MainActivity.class);
Hello.this.startActivity(i);
Hello.this.finish();
}
}, 5000);
}
}
For example: my app calls a native settings activity, by
Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(myIntent, CODE);
Then when it is finished (by pressing the back button for example) I want to know. I tried this way, but the onActivityResult() wasn't called when the native activity was finalized... so my app wasn't informed...
How I have to do? Anyone knows?
Thanks...
EDIT:
Thanks every one.
The complete code is that:
public class MainActivity extends AppCompatActivity {
public static final int DIALOG_CODE = 0x1;
private TextView txtGps;
private TextView txtNet;
private LocationManager manager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
first();
}
private void checkConfigs() {
boolean gps = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean net = manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
setWidgets(gps, net);
if (gps && net){
Toast.makeText(this, "Configurações Ok!", Toast.LENGTH_SHORT).show();
} else {
DialogConfig.exibDialog(getFragmentManager());
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if ((requestCode == DIALOG_CODE) && (resultCode == RESULT_OK)){
checkConfigs();
} else {
Toast.makeText(this, "As config não foram alteradas!", Toast.LENGTH_SHORT).show();
}
}
public void setWidgets(boolean gsp, boolean net){
if (gsp){
txtGps.setText(R.string.gps_hab);
} else {
txtGps.setText(R.string.gps_n_hab);
}
if (net){
txtNet.setText(R.string.wifi_hab);
} else {
txtNet.setText(R.string.wifi_n_hab);
}
}
private View.OnClickListener onClickCheck() {
return new View.OnClickListener() {
#Override
public void onClick(View v) {
checkConfigs();
}
};
}
#SuppressWarnings("ConstantConditions")
private void first() {
txtGps = (TextView) findViewById(R.id.txt_gps);
txtNet = (TextView) findViewById(R.id.txt_net);
manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
findViewById(R.id.btn_check).setOnClickListener(onClickCheck());
}
public static class DialogConfig extends DialogFragment {
public static void exibDialog(FragmentManager fm){
new DialogConfig().show(fm, "dialog");
}
#Override
public android.app.Dialog onCreateDialog(Bundle savedInstanceState) {
return new AlertDialog.Builder(getActivity())
.setTitle("As conf não estão corretas! Alt configs?")
.setPositiveButton("Ok", onOk())
.setNegativeButton("Cancel", onCancel())
.create();
}
private DialogInterface.OnClickListener onCancel() {
return new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dismiss();
}
};
}
private DialogInterface.OnClickListener onOk() {
return new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent myIntent = new Intent( Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(myIntent, DIALOG_CODE);
}
};
}
}
}
[Resolved]
Thanks again to every one, I tried again, creating a interface of callback in dialog, so the activity could be informed and call the other native settings activity by itself , and got the response in onActivityResult(), but comparing only a code (not by RESULT_OK), This way worked. But there is a other way (like was suggested) that use the lifecycle, to me seems more easy.
I basically tried what you tried and it works for me.
startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), 1);
and for onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d(PREFIX, "onActivityResult");
}
When I came back to the app, onActivityResult was called.
Not sure what you are doing different. can you show your onActivityResult code?
How do I take the 'this' value ( from the 6th line) and make it into a string?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_qrscanner);
fragment = (BarcodeFragment)getSupportFragmentManager().findFragmentById(R.id.sample);
fragment.setScanResultHandler(this);
btn = ((Button)findViewById(R.id.scan));
btn.setEnabled(false);
}
For example instead of just toasting the value, can I use the value and make it into a string and then carrying it into another activity.
#Override
public void scanResult(ScanResult result) {
btn.setEnabled(true);
Intent intent = new Intent(QrscannerActivity.this,ProductInfoActivity.class);
startActivity(intent);
Toast.makeText(this, result.getRawResult().getText(), Toast.LENGTH_LONG).show();
}
You should use the Google ZXing Barcode Scanner library and with the below code:
extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
HandleClick hc = new HandleClick();
findViewById(R.id.butQR).setOnClickListener(hc);
findViewById(R.id.butProd).setOnClickListener(hc);
findViewById(R.id.butOther).setOnClickListener(hc);
}
private class HandleClick implements OnClickListener{
public void onClick(View arg0) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
switch(arg0.getId()){
case R.id.butQR:
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
break;
case R.id.butProd:
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
break;
case R.id.butOther:
intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR");
break;
}
startActivityForResult(intent, 0); //Barcode Scanner to scan for us
}
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
TextView tvStatus=(TextView)findViewById(R.id.tvStatus);
TextView tvResult=(TextView)findViewById(R.id.tvResult);
if (resultCode == RESULT_OK) {
tvStatus.setText(intent.getStringExtra("SCAN_RESULT_FORMAT"));
tvResult.setText(intent.getStringExtra("SCAN_RESULT"));
} else if (resultCode == RESULT_CANCELED) {
tvStatus.setText("Press a button to start a scan.");
tvResult.setText("Scan cancelled.");
}
}
}
}
I have a Parent activity which is sending data to child activity but the child is not returning the result. I posted portion of code from both activity altogether below- Theres a few code that I didnt post for unnecessity.
public class TdeeActivity extends Activity {
public static final int CALLED_ACTIVITY = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tdee);
Button ok=(Button)findViewById(R.id.btnOk);
ok.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent bmr= new Intent(TdeeActivity.this,BMRActivity.class);
startActivityForResult(bmr,CALLED_ACTIVITY);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case CALLED_ACTIVITY:
if (resultCode == RESULT_OK) {
Toast.makeText(this, "THE RESULT-"+data.getExtras().getString("result"),
Toast.LENGTH_SHORT).show();
}
}
}
} // end class
public class BMRActivity extends Activity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bmr);
Button btnOk=(Button)findViewById(R.id.btnOk);
btnOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showResult();
}
});
public void showResult() {
Intent data= new Intent();
data.putExtra("result",result);
setResult(RESULT_OK, data);
finish();
}
}
}// end class
I tested you code in a dummy project and it was working fine at my end.. following is the code for both activity:
public class ParentActivity extends Activity {
private static final int CALLED_ACTIVITY = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent bmr = new Intent(ParentActivity.this, ChildActivity.class);
startActivityForResult(bmr, CALLED_ACTIVITY);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case CALLED_ACTIVITY:
if (resultCode == RESULT_OK) {
Toast.makeText(this, "THE RESULT-"+data.getExtras().getString("result"),
Toast.LENGTH_SHORT).show();
}
}
}
}
public class ChildActivity extends Activity {
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Returning result from child activity
Intent data = new Intent();
data.putExtra("result", "from child"
+ this.getCallingActivity().getClassName());
setResult(RESULT_OK, data);
finish();
}
}
So please post more code so that issue can be found..
