I am trying to activate speech like I am pressing the toogleButton, and i copyed the code from the toogleButton to the handler.
Everything is ok, i mean if i click the toogleButton it works, but when i recive the message that cointains "ello" in the handler, the speechRecognizer starts but closes very quickly, this happens every time i send that message.
Also it seems like a new activity i created when i trigger the handler with that message, but the same functions in the toogleButton work.
Any ideea how can i make this work ? I want functionality in the toogleButton, but in the handler too, so i can trigger speechRecognition with a message or something inside handler.
I think the problem is that you're changing the toggleButton's state inside the Handler
toggleButton.setChecked(true);
And this will trigger the OnCheckedChangeListener. But this should start the speech recognition again (because you set it to true), not stop it.
Try to call only toggleButton.setChecked(true); in your Handler, see if that resolves the problem, for example:
if(sbprint.contains("ello")){
toggleButton.setChecked(true);
}

I'm creating a security settings part in my app.
There are 3 radio buttons that allow the user to choose between a passcode, TouchID or nothing. All radio buttons are unchecked by default. When clicking on a radio button (e.g. to use passcode), the code checks to see if the user has set up a passcode. If the user hasn't, a dialog is shown and the radio button remains unchecked. The user then goes and sets up a passcode (setUpPasscode button).
Once set up, the passcode activity closes with the return case '2' and the radio button with the passcode option should be checked. It isn't however. When I re-launch the application, the button is checked though. It somehow isn't checked immediately after finishing the previous activity but it is technically checked. What am I doing wrong?

I would suggest to overload the onResume method and checking the state of your radio buttons as that will be the last control where the flow will leave your activity.
Hello StackOverflow's users,
I'm developing a Music Player App for android. In my main activity when the user clicks on a song I start a new intent that displays PlayerActivity. In there, I initialize a MediaPlayer and all the other UI elements. When the user clicks the back button, I bring them back to the main activity and the song continues to play in the background. The same thing happens if they exit the application. Now I was wondering if it's fine to do something like this or if I should instead start a new Service for the MediaPlayer from the PlayerActivity class instead of doing it in there.
PlayerActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
Bundle extras = getIntent().getExtras();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));

getWindow().setNavigationBarDividerColor(getResources().getColor(R.color.white));

Song song = manager.getCurrentSong();
boolean wasCall = extras != null && extras.containsKey("call");
if (!wasCall && manager.hasStarted()) {
MediaPlayer mediaPlayer = manager.getMediaPlayer();
mediaPlayer.pause();
mediaPlayer.stop();
}
if (!wasCall) {
mp = MediaPlayer.create(this, Uri.parse(song.getPath()));
mp.setLooping(true);
mp.seekTo(0);
mp.setVolume(0.5f, 0.5f);
} else {
mp = manager.getMediaPlayer();
mp.setLooping(true);
mp.setVolume(0.5f, 0.5f);
}
totalTime = mp.getDuration();
artImage.setImageBitmap(Bitmap.createScaledBitmap(song.getIcon(), 250, 250, true));
totalTimeLabel.setText(createTimeLabel(totalTime));
songName = findViewById(R.id.songName);
songName.setText(song.getName());
songAuthor = findViewById(R.id.songAuthor);
songAuthor.setText(song.getArtist());

toolbar.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));

toolbar.getNavigationIcon().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setTitle(Html.fromHtml("<font color='#ffffff'>MySound</font>"));

Here is a Music Service that I implemented in my book.
https://github.com/Wickapps/Practical-Android-MusicService
This implementation includes play, stop, and seek forward, but you could add other functions.
Service is the best architecture for future scalability.
There is a MainActivity.java which starts the service.
MusicService.java is the service implementation.
Hope this helps.
If you want your app to keep playing audio while it's in background ( like spotify ), then yes, it is a must to use a foreground service.
Unfortunately it's more complex than your current implementation.
This is a nice starting point : https://developer.android.com/guide/topics/media-apps/audio-app/building-an-audio-app
I have several buttons that respond to an onClick. When the buttons are pressed, it triggers a text to speech that says the name of the button and some music that corresponds to the button. However, the app glitches because you can press a different button while the music and text to speech for one button are still running. Is there a way to wait for the text to speech and music to stop playing before allowing another click? Any help would be greatly appreciated!! Thanks a lot!!!
public void onClick(View view) {
Resources res = getResources();
Button btn = (Button) view;
final TextView tv = (TextView) findViewById(R.id.color_text);
textViewString = tv.getText().toString();
switch (view.getId()) {
case R.id.green_button:
String greenString = res.getString(R.string.Green);
tv.setText(greenString);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
tts.speak(greenString, TextToSpeech.QUEUE_FLUSH, null);
} else {
tts.speak(greenString, TextToSpeech.QUEUE_FLUSH, null, null);
}
MediaPlayer green = MediaPlayer.create(this, R.raw.green);
green.start();
break;
case R.id.red_button:
String redString = res.getString(R.string.Red);
tv.setText(redString);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
tts.speak(redString, TextToSpeech.QUEUE_FLUSH, null);
} else {
tts.speak(redString, TextToSpeech.QUEUE_FLUSH, null, null);
}
MediaPlayer red = MediaPlayer.create(this, R.raw.red);
red.start();
break;
It seems that you must invoke tts.shutdown() in onClick() and then create the other tts object.
public void onClick(View view) {
tts.shutdown();
tts = new TextToSpeech(context, listener)
/* your code */
}
you can put if statement that checks if tts object is playing , tts.isSpeaking() return boolean true if speaking.
I am working with an Arduino and trying use two toggle buttons to connect and enable the Arduino. I don't want to be able to press the enable button until I have connected the robot. Here is my main activity:
public class MainActivity extends Activity {
Arduino arduino = null;
ToggleButton enable, connect;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ToggleButton connect = (ToggleButton) findViewById(R.id.buttonConnect);
ToggleButton enable = (ToggleButton) findViewById(R.id.buttonEnable);
}
public void onToggleClicked(View view) {
switch(view.getId()) {
case R.id.buttonConnect:
boolean on = ((ToggleButton) view).isChecked();
if(on){
//Take the text from editText1 and make it the IP Address
EditText text = (EditText)findViewById(R.id.editText1);
String ip = text.getText().toString();
arduino = new Arduino(ip);
arduino.connect();
arduino.disable();
} else {
arduino.disable();
arduino.disconnect();
enable.setChecked(false);
}
break;
case R.id.buttonEnable:
boolean click = ((ToggleButton) view).isChecked();
if(click && connect.isChecked()) {
arduino.enable();
}else {
System.out.println("Not Connected");
enable.setChecked(False);
arduino.disable();
}
break;
default:
break;
}
}
I know the program is not reaching the else statement in the buttonEnable case because it is not printing out "Not Connected." I have also tried to use connect.isEnabled()in my if statement but that doesn't work either. Does anybody have answer? Thank you!
Try to set on click listener to attach the code execution to you button
I've to do a pair of fixes to an Android app although I don't really know about Android, but I'm getting problems in something that I don't think should be that difficult, I just want that when an OK button is pressed and some conditions haven't been fulfilled it displays a message and keeps on the same screen until data is correct or the user cancels, but I've tried it for some time and whatever I try it always displays the message and after that a white screen appears, even trying to search for examples on the internet.

Hope you can help me with this thing, as I would find pretty annoying to have to learn android from the beginning to make something that I've been able to do in another programming languages in 5 minutes or less without knowing them at all.
Create two instance variables or class varibles like this
private Toast toast;
private boolean stop = false;
Write a method called this
private void showInfiniteToast() {
stop = false;
Thread t = new Thread() {
public void run() {
try {
while (true) {
if (!stop) {
toast.show();
} else {
toast.cancel();
return;
}
sleep(1850);
}
} catch (Exception e) {
Log.e("Infinite Toast", "Error "+ e.getLocalizedMessage());
}
}
};
t.start();
}
Now in the oncreate create the toast and call this method
toast = Toast.makeText(getApplicationContext(), "Test", Toast.LENGTH_LONG);
showInfiniteToast();
Now if you want to change the toast message use this
toast.setText("message");
To stop the toast call any of these
//Call anyone of them
stop = true;
toast.cancel();
To implement your own custom view use this
View mView;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mView = inflater.inflate(R.layout.mylayout, null);
toast.setView(mView);
Here is the complete file
public class MainActivity extends Activity implements OnClickListener {
Button btnChange, btnStop, btnShow;
private Toast toast;
private boolean stop = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnShow = (Button) findViewById(R.id.btnShow);
btnShow.setOnClickListener(this);
btnChange = (Button) findViewById(R.id.btnChange);
btnChange.setOnClickListener(this);
btnStop = (Button) findViewById(R.id.btnStop);
btnStop.setOnClickListener(this);
toast = Toast.makeText(getApplicationContext(), "Test",
Toast.LENGTH_LONG);
showInfiniteToast();
}
private void showInfiniteToast() {
stop = false;
Thread t = new Thread() {
public void run() {
try {
while (true) {
if (!stop) {
toast.show();
} else {
toast.cancel();
return;
}
sleep(1850);
}
} catch (Exception e) {
Log.e("Infinite Toast", "Error "+ e.getLocalizedMessage());
}
}
};
t.start();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnShow:
showInfiniteToast();
break;
case R.id.btnChange:
toast.setText("Added");
break;
case R.id.btnStop:
stop = true;
toast.cancel();
break;
default:
break;
}
}
}
First of all create your layouts using xml and inflate the view like this:
LayoutInflater li = (LayoutInflater) <ACTIVITY_NAME>.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = li.inflate(R.layout.<LAYOUT_NAME>, parent, false);
or
View view = li.inflate(R.layout.<LAYOUT_NAME>, null);
If there is no parent view to attach the inflated view to. Then you can edit objects in your view by doing:
EditText edit = (EditText) findViewById(R.id.edit1);
edit.setText("example");
Doing so just makes your code much more cleaner.
The methods: setPositiveButton, setNeutralButton and setNegativeButton are coded so that when they are pressed, the dialog will close after it has finished executing the code in the listener.
If your Android app is running on the main thread for over 5 seconds then the app will throw an error saying that the app is no longer responding. If you wished to do a long action then you should use an AsyncTask or a Service.
I believe you are wanting to have a progress bar of some kind. I will link you to a
tutorial that will show you how to acheive that side of things. Check here
Hopefully this points you in the right direction.
create a dialogBuilder, and override the negative and positive buttons, and on the click listeners do whatever you want. This will prevent the dialog from closing.
Like this:
Create the builder, intialize it, set it for eg:
builder.setView(view);
builder.setCancelable(false);
override the ondismiss listener, and onshow listener like:
builder.setOnDismissListener(new OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
if(!errorFlag) {
dialog.dismiss();
}
}
});
builder.setOnShowListener(new OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
Button b = builder.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// write the logic here, and maintain a flag.
// if the flag is true then only dismiss the dialog else show another one
}
Override the negative button also.
show the builder using builder.show()
