I am learning Android Studio and I have a question: I wanna say something in chinese and there compare the word/phrase I said with the one that was displayed at the screen. And if these two words are equals - make text green. else - red. But it always red after I press the mic button.
Will appriciate any help
public class SpeakingActivity extends AppCompatActivity {
private static final int REQUEST_CODE_SPEECH_INPUT = 1000;
TextView mTextView;
TextView input;
ImageButton mImageButton;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.speakingfromhome);
button = findViewById(R.id.nextSpeaking);
mTextView = findViewById(R.id.output);
mImageButton = findViewById(R.id.image);
input = findViewById(R.id.input);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
changeQuestions();
mTextView.setTextColor(Color.BLACK);
}
});
mImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speak();
checkIfCorrect();
}
});
}
private void checkIfCorrect() {
if (input.toString().equals(mTextView.toString()))
mTextView.setTextColor(Color.GREEN);
else
mTextView.setTextColor(Color.RED);
}
private void changeQuestions() {
input.setText("基辅");
}
private void speak() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.CHINA.toString());
try {
startActivityForResult(intent, REQUEST_CODE_SPEECH_INPUT);
} catch (Exception ex) {
Toast.makeText(this, "" + ex.getMessage(), Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
mTextView.setText(result.get(0));
}
break;
}
}
}
}

The function checkIfCorrect() is the problem
Change it to:
input.toString() -> input.getText()
mTextView.toString() -> mTextView.getText()
Like:
input.getText().equals(mTextView.getText())
with getText() get the text of the TextView, doint input.toString() convert the object TextView to String
your checkIfCorrect function must look like:
private void checkIfCorrect() {
if (input.getText().equals(mTextView.getText()))
mTextView.setTextColor(Color.GREEN);
else
mTextView.setTextColor(Color.RED);
}
A better way:
private void checkIfCorrect() {
mTextView.setTextColor((input.getText().equals(mTextView.getText())) ? Color.GREEN : Color.RED )
}

How I get the response of a native activity?

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

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());
}

.create();
}
private DialogInterface.OnClickListener onCancel() {

[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?

onActivityResult is not being called

I'm using Activitygroup concept to handle multiple activities under single tab. What I am doing in first activity of tab, I fetch image from gallery and camera, and after that when user selects image that image should move to second activity but those both activities must remain under the same tab. Here is my code...
TabGroupActivity.java
public class TabGroupActivity extends ActivityGroup {
private ArrayList<String> mIdList;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (mIdList == null) mIdList = new ArrayList<String>();
}
#Override
public void finishFromChild(Activity child) {
LocalActivityManager manager = getLocalActivityManager();
int index = mIdList.size()-1;
if (index < 1) {
finish();
return;
}
manager.destroyActivity(mIdList.get(index), true);
mIdList.remove(index); index--;
String lastId = mIdList.get(index);
Intent lastIntent = manager.getActivity(lastId).getIntent();
Window newWindow = manager.startActivity(lastId, lastIntent);
setContentView(newWindow.getDecorView());
}
public void startChildActivity(String Id, Intent intent) {
Window window = getLocalActivityManager().startActivity(Id,intent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT));
if (window != null) {
mIdList.add(Id);
setContentView(window.getDecorView());
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
//preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
onBackPressed();
return true;
}
return super.onKeyUp(keyCode, event);
}
public void onBackPressed() {
int length = mIdList.size();
if ( length > 1) {
Activity current = getLocalActivityManager().getActivity(mIdList.get(length-1));
current.finish();
}
}
}

public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
}
}
But the image is not being displayed in second activity. How to do this?

call this way
GalleryPic.this.startActivityForResult(intent, REQUEST_ID);

can't call onactivity result function after child activity is finished

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();
}

setResult doesn't call onActivityResult

I have two activities which starts the same sub-activity for result.
But in only one of them onActivityResult works.
Here are parts of my code
This is my first Activity. As you can see it calls NewCommentActivity in startActivityForResult and this part works fine
public class OfferActivity extends ListActivity implements View.OnClickListener {
...
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.offer_menu_comment:
Intent commentIntent = new Intent(this, NewCommentActivity.class);
commentIntent.putExtra(Offer.OFFER, offer);
startActivityForResult(commentIntent, COMMENT_REQUEST_CODE);
return true;
...
default:
return super.onOptionsItemSelected(item);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case COMMENT_REQUEST_CODE:
if (resultCode == RESULT_OK) {
Integer commentCnt = offer.getCommentCnt() + 1;
offer.setCommentCnt(commentCnt);
commentButton.setText(getString(R.string.offer_comments, offer.getCommentCnt()));
}
break;
}
}
...
}
Here is my second activity which calls NewCommentActivity too, but here onActivityResult is not called
public class CommentsActivity extends ListActivity{
...
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
...
case COMMENT_ITEM_ID:
Intent commentIntent = new Intent(this, NewCommentActivity.class);
commentIntent.putExtra(Offer.OFFER, offer);
startActivityForResult(commentIntent, COMMENT_REQUEST_CODE);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case COMMENT_REQUEST_CODE:
if (resultCode == RESULT_OK) {
Integer commentCnt = offer.getCommentCnt() + 1;
offer.setCommentCnt(commentCnt);
Comment comment = data.getParcelableExtra(Comment.COMMENT);
commentImageListAdapter.addItemAtFront(comment);
}
break;
}
}
...
}
And here is code for NewCommentActivity :
public class NewCommentActivity extends Activity implements View.OnClickListener {
private static final String TAG = "Gift/NewCommentActivity";
private Offer offer;
private EditText editText;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_comment);
offer = getIntent().getParcelableExtra(Offer.OFFER);
editText = (EditText) findViewById(R.id.new_comment_text);
Button button = (Button) findViewById(R.id.new_comment_button);
button.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (editText.getText().length() > 0) {
new AddCommentAsyncTask().execute(offer, editText.getText().toString());
}
}
private class AddCommentAsyncTask extends AsyncTask<Object, Void, Comment> {
private String errorString;
private ProgressDialog progressDialog;
#Override
protected Comment doInBackground(Object... objects) {
Offer offer = (Offer) objects[0];
String text = (String) objects[1];
Comment comment = null;
try {
comment = ServiceContainer.getService().addComment(offer, text);
} catch (OfferException e) {
Log.e(TAG, "exception in comment", e);
int id;
if ((id = e.getErrorStringId()) != -1) {
errorString = getString(id);
} else {
errorString = e.getLocalizedMessage();
}
cancel(false);
}
return comment;
}
#Override
protected void onPreExecute() {
progressDialog = Utils.newSpinnerDialog(NewCommentActivity.this, R.string.sending);
}
#Override
protected void onCancelled() {
progressDialog.dismiss();
AlertDialog.Builder builder = Utils.newAlertDialog(NewCommentActivity.this, errorString, true);
builder.setPositiveButton(R.string.dialog_ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
new AddCommentAsyncTask().execute(offer, editText.getText().toString());
}
})
.setNegativeButton(R.string.dialog_cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
setResult(RESULT_CANCELED);
finish();
}
})
.create()
.show();
}
#Override
protected void onPostExecute(Comment comment) {
progressDialog.dismiss();
Intent intent = new Intent();
intent.putExtra(Comment.COMMENT, comment);
setResult(RESULT_OK, intent);
finish();
}
}
And finally AndroidManifest for all activities:
<activity android:name=".activity.OfferActivity"
android:configChanges="orientation"/>
<activity android:name=".activity.CommentsActivity"
android:configChanges="orientation"
android:label="#string/comment_activity_title"/>
<activity android:name=".activity.NewCommentActivity"
android:windowSoftInputMode="adjustResize"
android:configChanges="orientation"
android:label="#string/new_comment_activity_title"/>
</application>
Please help me.
Thanks.
