I am trying to set a waveInApp library http://www.materialup.com/posts/waveinapp
I have declared all the required thing .The app
working but the background wave is not working .I am not able to set the wave function as a beginner in android development .
I am able to set the all the basic things including the media player.
Here I am not able to set the speech recognization handler
Here is what I have done
import android.content.Context;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;
import com.cleveroad.audiovisualization.AudioVisualization;
import com.cleveroad.audiovisualization.DbmHandler;
import com.cleveroad.audiovisualization.SpeechRecognizerDbmHandler;
import com.cleveroad.audiovisualization.VisualizerDbmHandler;
public class MainActivity extends AppCompatActivity {
private AudioVisualization audioVisualization;
private Context context;
private ImageButton button1,button2;
private MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
audioVisualization = (AudioVisualization)findViewById(R.id.visualizer_view);
button1=(ImageButton)findViewById(R.id.imageButton);
button2=(ImageButton)findViewById(R.id.imageButton2);
mediaPlayer =MediaPlayer.create(this,R.raw.song);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"playing",Toast.LENGTH_SHORT).show();
mediaPlayer.start();
}
});
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"pause",Toast.LENGTH_SHORT).show();
mediaPlayer.pause();
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
audioVisualization.linkTo(vizualizerHandler);
// set speech recognizer handler
SpeechRecognizerDbmHandler speechRecHandler = DbmHandler.Factory.newSpeechRecognizerHandler(context);
speechRecHandler.innerRecognitionListener(...);
audioVisualization.linkTo(speechRecHandler);
}
});
}
#Override
public void onResume() {
super.onResume();
audioVisualization.onResume();
}
#Override
public void onPause() {
audioVisualization.onPause();
super.onPause();
}
}
So how to set the above handeler. I am not able to set the connect audio visualization view to audio output . How to set the following method with the media player
// set speech recognizer handler
SpeechRecognizerDbmHandler speechRecHandler = DbmHandler.Factory.newSpeechRecognizerHandler(context);
speechRecHandler.innerRecognitionListener(...);
audioVisualization.linkTo(speechRecHandler);
// set audio visualization handler. This will REPLACE previously set speech recognizer handler
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
audioVisualization.linkTo(vizualizerHandler);
Except this all are working.any hint or advice will be helpfull.

So can some one tell me why fragment is used and how I can set this in my main activity?
I know i am late to post this answer...but for future use try this
check my code you will find your answer
first of all in the liberay you have to make some changes in your xml.
<com.cleveroad.audiovisualization.GLAudioVisualizationView
android:id="#+id/visualizer_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:av_bubblesSize= "#dimen/bubble_size"
app:av_bubblesRandomizeSizes= "true"
app:av_wavesHeight= "#dimen/wave_height"
app:av_wavesFooterHeight="#dimen/footer_height"
app:av_wavesCount="7"
app:av_layersCount="4" />
then
private VisualizerDbmHandler handler;
MediaPlayer mp ;
private AudioVisualization audioVisualization;
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View ve = inflater.inflate(R.layout.cat, container, false);
ibCapture = (ImageButton) ve.findViewById(R.id.ibCapture);
audioVisualization = (AudioVisualization)ve.findViewById(R.id.visualizer_view);
hell();
return ve;
}
ibCapture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (bool) {
bool = false;
mp = MediaPlayer.create(getContext(), R.raw.blackcat);
mp.setLooping(true);
handler = VisualizerDbmHandler.Factory.newVisualizerHandler(getContext(),mp);
audioVisualization.linkTo(handler);
mp.start();
((home)getActivity()).vis();
} else {
bool = true;
((home)getActivity()).visgone();
stopPlaying();
}
}
});
Replace
audioVisualization = (AudioVisualization) glAudioVisualizationView;
With
audioVisualization = (AudioVisualization)findViewById(R.id.glAudioVisualizationView);
glAudioVisualizationView should be id of AudioVisualization in your layout file
define
private AudioVisualization audioVisualization;
initialize it
audioVisualization = (AudioVisualization) view.findViewById(R.id.visualizer_view);
for speech use below code
SpeechRecognizerDbmHandler speechRecHandler = DbmHandler.Factory.newSpeechRecognizerHandler(getContext());
speechRecHandler.innerRecognitionListener();
audioVisualization.linkTo(speechRecHandler);
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getContext().getPackageName());
speechRecHandler.startListening(intent);
for a media on your device use below code, Sandeep Singh Answer
MediaPlayer mp = MediaPlayer.create(getContext(), R.raw.blackcat);
mp.setLooping(true);
handler = VisualizerDbmHandler.Factory.newVisualizerHandler(getContext(),mp);
audioVisualization.linkTo(handler);
mp.start();

I am trying to maintain the ui changes so that when restarting the activity, the instance of my fragment become used with the changes of the buttons. So I found setRetainInstance(true) doesn't destroy the fragment object, however, the resulted view is destroyed. So I overrode onSaveInstance in the fragment class to save the ids of the resources that is called in the event handlers for setting it the next time the activity is created. The result was unexpected, at least for me:
1. The view of the fragment is destroyed when recreating the activity and the fragments instance become reattached to the new activity instance.
2. Event handlers become non-operational, so I don't know where is the problem.
Here is the code of the activity class:
package com.voicenoteinc.ticatactoy;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.PersistableBundle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
Tic_Fragment s;
FragmentManager manager;
String TAG_FRAGMENT = "tag_fragment";
FragmentTransaction trans;
boolean retained = true;
String COLOR_ARRAY;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
manager = getFragmentManager();
s = (Tic_Fragment) manager.findFragmentByTag(TAG_FRAGMENT);
if(s == null){
s = new Tic_Fragment();
retained = false;
trans = manager.beginTransaction();
trans.add(R.id.fragment_container,s,TAG_FRAGMENT).commit();

Please help. I tried my best but couldn't fix.
Remove AsyncTask Implementation And Call Required Methods From UI Thread
Use Below Code :
private void initViews() {
mVrVideoView = (VrVideoView) findViewById(R.id.video_view);
mSeekBar = (SeekBar) findViewById(R.id.seek_bar);
mVolumeButton = (Button) findViewById(R.id.btn_volume);
mVrVideoView.setEventListener(new ActivityEventListener());
try {
VrVideoView.Options options = new VrVideoView.Options();
options.inputType = VrVideoView.Options.TYPE_MONO;
mVrVideoView.loadVideoFromAsset("sea.mp4", options);
} catch( IOException e ) {
//Handle exception
}
mSeekBar.setOnSeekBarChangeListener(this);
mVolumeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
onVolumeToggleClicked();
}
});
}
I dont know much about videoview but I show in your code that you are trying to access some the features in doInbackground method. The doINbackground method runs on a separate thread from the UI thread so that complex ant time consuming tasks do not block the UI thread. You can implement the features you are implementing in doINbackground method in the onCreate method or if you still need to use doInbackground you can access the UI thread inside doInbackground using runOnUiThread as follows
runOnUiThread(new Runnable() {
#Override
public void run() {
//your code here
}
});
Although i have read similar post-questions, i havent found solution to my problem. As you can see in the title i cant change Textview in TextFragment.

Guys also note tha i have tried and this in mainActivity but nothing changed.
inter inte;

super.onVisitStart(visit);
name=visit.getPlace().getName().toString();
if (name!=null){
inte.respond(name);
inte.barstatus2();
}
}
};
EDIT:
if instead of
public void changestatus(){
placeEventListener= new PlaceEventListener() {
#Override
public void onVisitStart(Visit visit) {
super.onVisitStart(visit);
name=visit.getPlace().getName().toString();
if (name!=null){
respond(name);
barstatus2();
}
}
use
#Override
protected void onStart() {
super.onStart();
placeEventListener= new PlaceEventListener() {
#Override
public void onVisitStart(Visit visit) {
super.onVisitStart(visit);
name=visit.getPlace().getName();
if (name!=null){
respond(name);
barstatus2();
}
}
};
i can make changes...can you explain me why??
i dont want this block of code running onStart().
i want this block of code working inside a method.
You need to make little change in your textFragment, initialize TextView in onCreateView() method as,
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.text_fragment, container,false);
text1 = (TextView)getActivity().findViewById(R.id.textF);
text1.setText("Press Start button to find buildings near you");
return view;
}
I have a simple app for voice recognition that prints all the possible string ArrayList decoded. The problem is that it only works if I don't stop/pause between words. If I have a slight pause (very short as if I was speking normally) the app stops. I looked at the parameter SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS but it didn't change anything.
Any clue from a voice recognition specialist?
Here is my code:
package com.bernard.vtt;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
public class MainActivity extends Activity implements RecognitionListener {
private TextView mText;
SpeechRecognizer speech = null;
private Intent recognizerIntent;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button speakButton = (Button) findViewById(R.id.btn);
mText = (TextView) findViewById(R.id.textView1);
speech = SpeechRecognizer.createSpeechRecognizer(this);
speech.setRecognitionListener(this);
recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE,
"en");
recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
this.getPackageName());
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
speech.startListening(recognizerIntent);
}
});
}
#Override
public void onResults(Bundle results) {
ArrayList<String> matches = results
.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
String text = "";
assert matches != null;
for (String result : matches)
text += result + "\n";
mText.setText(text);
speech.stopListening();
}
#Override
public void onReadyForSpeech(Bundle params) {
}
#Override
public void onBeginningOfSpeech() {
}
#Override
public void onRmsChanged(float rmsdB) {
}
#Override
public void onBufferReceived(byte[] buffer) {
}
#Override
public void onEndOfSpeech() {
}
#Override
public void onError(int error) {
}
#Override
public void onPartialResults(Bundle partialResults) {
}
#Override
public void onEvent(int eventType, Bundle params) {
}
I believe the built-in speech recognition does not continually run. It is designed to hear one voice input and give results. If you want to continually listen, you need to restart recognition on each onResults callback. I also believe SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS has a max value, which is why changing it has little effect.

mSpeechRecognizer.setRecognitionListener(new listener());
startrecording();
}
public void startrecording() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
getPackageName());
