button perform click not working

This is my code to perform click automatically when the activity opens but it is not working
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notify);
editspeak = (EditText) findViewById(R.id.editspeak);
btspeak=(Button)findViewById(R.id.bt);
// speakout();
// mydb = new DBhandler(this);
SharedPreferences preferences=getSharedPreferences(PREFS,0);
String name=preferences.getString("NAME",null);
editspeak.setText(name);
t1=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
t1.setLanguage(Locale.US);
}
}
});
btspeak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String text = editspeak.getText().toString();
t1.speak(text, TextToSpeech.QUEUE_FLUSH, null);
// bt.setPressed(false);
// bt.invalidate();
}
});
btspeak.performClick();

The problem here is that you call speak before the TextToSpeech is fully initialised (you can add a few logs to check this). To fix this behaviour you can use performClick in this way to delay the call until everything else is finished initialising:
btspeak.post(new Runnable() {
#Override
public void run() {
btspeak.performClick();
}
});

Android text to speech setOnUtteranceCompleted not applicable

I'm trying to get the activity to finish after it's finished speaking but for some reason I cannot fathom it tells me that the setOnUtteranceCompleted not applicable for text to speech. I'm new to android programming so please be gentle :-)
Here's the code...
public class SpeakActivity extends Activity implements OnUtteranceCompletedListener{
Random randnum = new Random();
TextToSpeech tts = null;
private boolean ttsIsInit = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_speak);
// Show the Up button in the action bar.
setupActionBar();
startTextToSpeech();
}
void startTextToSpeech(){
final int randint = randnum.nextInt(4);
final String text = ((GlobVars) this.getApplication()).getResponse(randint);
tts = new TextToSpeech(this, new OnInitListener() {
public void onInit(int status) {
tts.setOnUtteranceCompletedListener(this);
if (status == TextToSpeech.SUCCESS) {
ttsIsInit = true;
if (tts.isLanguageAvailable(Locale.ENGLISH) >= 0){
tts.setLanguage(Locale.ENGLISH);
}
tts.setPitch(0.5f);
tts.setSpeechRate(0.5f);
if (tts != null && ttsIsInit) {
Log.d("got ere", "spoken");
tts.speak(text, TextToSpeech.QUEUE_ADD, null);
}
}
}
});
}
// shut down tts to free the TTS resources
#Override
public void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
#Override
public void onUtteranceCompleted(String arg0) {
((GlobVars) this.getApplication()).setListen(true);
this.finish();
}
}

I am ot sure but as per the docs of setOnUtteranceCompletedListener(), you might need to use TextToSpeech.OnUtteranceCompletedListener listener as an argument. I think the way to use the function is as below. Note that use runOnUIThread method in case you want to make any changes to the UI on the call of the onUtteranceCompleted function.
TextToSpeech tts= new TextToSpeech(context, new OnInitListener() {
#Override
public void onInit(int status) {
tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
#Override
public void onUtteranceCompleted(String utteranceId) {
//Do things here
}
});
}
});
Source of above : Check onUtteranceCompleted does not get called? question.
Hope this helps.

Custom Adapter Listview Android

I hit my head against the wall, trying to solve this problem for some time. I'm not an experienced Android guy, so its solution might be really simple. That being said, I have the following code:
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.adminusers);
super.onCreate(savedInstanceState);
// set user_type for Viewall
mUserType = 0;
lv_adminusersListContent.addFooterView(footerView);
mUsersAdapter = new AdminUsersAdapter(mUsersList, AdminUsers.this);
lv_adminusersListContent.setAdapter(mUsersAdapter);
getUsersList();
}
private void getUsersList() {
if (UsefulFcts.isOnline(AdminUsers.this)) {
if (mThread != null && mThread.isAlive()) {
mThread.interrupt();
}
mThread = new Thread() {
#Override
public void run() {
mHandler.post(new Runnable() {
#Override
public void run() {
pDialog = new ProgressDialog(AdminUsers.this);
pDialog.setMessage("Loading.. Please wait!");
pDialog.setCancelable(false);
pDialog.show();
}
});
mUsersList.clear();
mUsersList.addAll(mServiceManager.getUsersList(mUserType,
0 + "", AdminServiceManager.sHowManyToLoad));
mArrayLength = mUsersList.size();
Log.d("arrayLength", String.valueOf(mArrayLength));
Log.d("total_results",
String.valueOf(ParserJSON.total_results));
mHandler.post(new Runnable() {
#Override
public void run() {
// refresh listview
mUsersAdapter.notifyDataSetChanged();
if (mArrayLength < ParserJSON.total_results) {
lv_adminusersListContent
.addFooterView(footerView);
} else if (mArrayLength >= ParserJSON.total_results) {
lv_adminusersListContent
.removeFooterView(footerView);
}
if (0 == mArrayLength) {
Toast.makeText(AdminUsers.this,
"No username found!",
Toast.LENGTH_SHORT).show();
}
pDialog.dismiss();
}
});
}
};
mThread.start();
} else {
Toast.makeText(AdminUsers.this, "Internet connection required!",
Toast.LENGTH_LONG).show();
}
}
#Override
protected void linkUI() {
// begin load_more view
footerView = AdminUsers.this.getLayoutInflater().inflate(
R.layout.loadmore, null);
btn_loadmore = (Button) footerView.findViewById(R.id.btn_loadmore);
// end load_more view
btn_adminusersViewall = (Button) findViewById(R.id.btn_adminusersViewall);
btn_adminusersAdmins = (Button) findViewById(R.id.btn_adminusersAdmins);
btn_adminusersClients = (Button) findViewById(R.id.btn_adminusersClients);
btn_adminusersDevs = (Button) findViewById(R.id.btn_adminusersDevs);
btn_adminAdd = (ImageButton) findViewById(R.id.btn_adminAdd);
lv_adminusersListContent = (ListView) findViewById(R.id.lv_adminusersListContent);
}
#Override
protected void setAction() {
// begin Buttons UnderHeader
btn_adminusersViewall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
UsefulFcts.setButtonClicked(btn_adminusersViewall,
btn_adminusersClients, btn_adminusersAdmins,
btn_adminusersDevs);
mUserType = 0;
mArrayLength = -1;
lv_adminusersListContent.removeFooterView(footerView);
getUsersList();
}
});
btn_adminusersClients.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
UsefulFcts.setButtonClicked(btn_adminusersClients,
btn_adminusersDevs, btn_adminusersAdmins,
btn_adminusersViewall);
mUserType = 1;
mArrayLength = -1;
// view.setVisibility(View.GONE);
getUsersList();
}
});
btn_adminusersDevs.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
UsefulFcts.setButtonClicked(btn_adminusersDevs,
btn_adminusersClients, btn_adminusersAdmins,
btn_adminusersViewall);
mUserType = 2;
mArrayLength = -1;
lv_adminusersListContent.removeFooterView(footerView);
getUsersList();
}
});
btn_adminusersAdmins.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mUserType = 3;
mArrayLength = -1;
lv_adminusersListContent.removeFooterView(footerView);
getUsersList();
}
});
// end Buttons UnderHeader
btn_loadmore.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mThread2 = new Thread() {
#Override
public void run() {
mHandler.post(new Runnable() {
#Override
public void run() {
progressBar = new ProgressDialog(
AdminUsers.this);
progressBar
.setMessage("Loading more projects.. ");
progressBar.setCancelable(true);
progressBar.show();
}
});
mUsersList.addAll(mServiceManager.getUsersList(
mUserType, String.valueOf(mArrayLength),
AdminServiceManager.sHowManyToLoad));
mArrayLength = mUsersList.size();
mHandler.post(new Runnable() {
#Override
public void run() {
mUsersAdapter.notifyDataSetChanged();
if (mArrayLength >= ParserJSON.total_results) {
lv_adminusersListContent.removeFooterView(footerView);
}
progressBar.dismiss();
}
});
};
};
mThread2.start();
}
});
Note: I basically have a listview which content is requested from a server depending on which button (looking like a tab) I'm pressing (mUserType = 0/1/2/3). I also use a Load More button (footerView = simple layout with a button).
Everything seems to work just fine, but after "playing" with the buttons a few times (random number!) it crashes, with the following exception thrown:
02-21 11:00:49.252: E/AndroidRuntime(11728): java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(2131296461, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]
So, I looked back at the code, but couldn't see any "not on UI thread" listview notification.
1. What could the problem be?
2. Is it necessary to use 2 threads (mThread and mThread2), or could I use the same one, as one's work should start when the other ends (or isn't it ?) and should I declare them static or not ?
Also pointing me to any "Good practices" tricks I could use in the future, or "Wrong practices" that I did would be much appreciated!
PS. linkUI() and setAction() are called in super().onCreate().

The error message seems understandable : you are modifying the adapter from mThread:
mUsersList.clear();
mUsersList.addAll(mServiceManager.getUsersList(mUserType,
0 + "", AdminServiceManager.sHowManyToLoad));
You can try something like this:
final List newUserList = mServiceManager.getUsersList(mUserType,
0 + "", AdminServiceManager.sHowManyToLoad);
mArrayLength = newUserList.size();
Log.d("arrayLength", String.valueOf(mArrayLength));
Log.d("total_results",
String.valueOf(ParserJSON.total_results));
mHandler.post(new Runnable() {
#Override
public void run() {
mUsersList.clear();
mUsersList.addAll(newUserList);
// refresh listview
mUsersAdapter.notifyDataSetChanged();

Activity will run, but not show up (Android)?

I'm just trying to test some stuff with a splash screen. The strangest thing happens when I run the app though. I can see my Log messages in the LogCat, but the activity itself won't show up. Once the loop finishes, it starts the next activity, which does in fact show up. If I comment out the UIThread, it will show up though. I know I'm doing something simple wrong, but I'm not sure what it is. Ideas?
XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#000000">
<ImageView
android:id="#+id/logoIV"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="50dp"
android:paddingTop="50dp"
android:src="#drawable/logoa"
/>
Java:
public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
final ImageView logo = (ImageView) findViewById(R.id.logoIV);
final int[] anim = new int[6];
anim[0]=R.drawable.logoa;
anim[1]=R.drawable.logob;
anim[2]=R.drawable.logoc;
anim[3]=R.drawable.logod;
anim[4]=R.drawable.logoe;
anim[5]=R.drawable.logof;
runOnUiThread(new Runnable() {
int img = 0, counter=0;
boolean up = true;
public void run() {
while(counter<21){
logo.setImageResource(anim[img]);
if(up){
img++;
if(img>=5)
up=false;
}else{
img--;
if(img<=0)
up=true;
}
try{
Thread.sleep(150);
}catch (InterruptedException e){
e.printStackTrace();
}
counter++;
Log.e("Tag",Integer.toString(counter));
}
if(counter>=21){
Intent creditsIntent = new Intent(Splash.this, TitlePage.class);
creditsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Splash.this.startActivity(creditsIntent);
}
}
});
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}

change your oncreate method like this
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splash);
final ImageView logo = (ImageView) findViewById(R.id.logoIV);
final int[] anim = new int[6];
anim[0] = R.drawable.logoa;
anim[1] = R.drawable.logob;
anim[2] = R.drawable.logoc;
anim[3] = R.drawable.logod;
anim[4] = R.drawable.logoe;
anim[5] = R.drawable.logof;
Thread t = new Thread(new Runnable()
{
int img = 0, counter = 0;
boolean up = true;
#Override
public void run()
{
while (counter < 21)
{
runOnUiThread(new Runnable()
{
public void run()
{
logo.setImageResource(anim[img]);
}
});
if (up)
{
img++;
if (img >= 5)
up = false;
}
else
{
img--;
if (img <= 0)
up = true;
}
try
{
Thread.sleep(150);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
counter++;
Log.e("Tag", Integer.toString(counter));
}
if (counter >= 21)
{
runOnUiThread(new Runnable()
{
public void run()
{
Intent creditsIntent = new Intent(Splash.this, TitlePage.class);
creditsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Splash.this.startActivity(creditsIntent);
}
});
}
}
});
t.start();
}

instead of calling runOnUiThread directly do the following:
new Timer().schedule(new TimerTask()
{
#Override
public void run()
{
runOnUiThread(new Runnable()
{
int img = 0, counter=0;
.....
}
}
}, 1000);
I'm not sure if your animation will work, but surely your activity will show up.

Android: waiting until tts speak is finished, then continue

I'm really struggling with something... I have a couple of sentences that I want to read, both verbally through tts speek function, and via text on screen, one sentence at a time.
I have the textview area ready, but putting it together is what I'm not getting. Either it will read all the sentences and only show the last one, or it will show and read only the first sentence.
Anyone know i how I can accomplish this goal?

I just ran into this issue, according to the speak method, use an UtteranceProgressListener. I found out this is not executed on the UI thread, so I had to use runOnUiThread() to get back to update the activity.
tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
}
#Override
public void onDone(String utteranceId) {
LettersActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
// Do something on UI thread
}
});
}
#Override
public void onError(String utteranceId) {
Log.e(TAG, "error on " + utteranceId);
}
});

boolean speakingEnd = tts.isSpeaking();
do{
speakingEnd = tts.isSpeaking();
} while (speakingEnd);
//Continue with code

public void speak(String message){
tts.speak(message, TextToSpeech.QUEUE_FLUSH, null);
while (tts.isSpeaking()){
System.Out.Println("Do something or nothing while speaking..")
}
}

Try this
public class MainActivity extends AppCompatActivity implements TextToSpeech.OnInitListener{
private boolean initialized;
private String queuedText;
private String TAG = "TTS";
private TextToSpeech tts;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tts = new TextToSpeech(this /* context */, this /* listener */);
tts.setOnUtteranceProgressListener(mProgressListener);
speak("hello world");
}
public void speak(String text) {
if (!initialized) {
queuedText = text;
return;
}
queuedText = null;
setTtsListener(); // no longer creates a new UtteranceProgressListener each time
HashMap<String, String> map = new HashMap<String, String>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "MessageId");
tts.speak(text, TextToSpeech.QUEUE_ADD, map);
}
private void setTtsListener() {
}
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
initialized = true;
tts.setLanguage(Locale.ENGLISH);
if (queuedText != null) {
speak(queuedText);
}
}
}
private abstract class runnable implements Runnable {
}
private UtteranceProgressListener mProgressListener = new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
} // Do nothing
#Override
public void onError(String utteranceId) {
} // Do nothing.
#Override
public void onDone(String utteranceId) {
new Thread()
{
public void run()
{
MainActivity.this.runOnUiThread(new runnable()
{
public void run()
{
Toast.makeText(getBaseContext(), "TTS Completed", Toast.LENGTH_SHORT).show();
}
});
}
}.start();
}
};
}
