How to use multiple images in splash screen in android

Hello i am trying to create splash screen in android with one image but i want to display multiple images at a time in splash screen when app is launch.
but it only displays one image please any solution for this please help me.
Here is my code.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
for(int i=0;i<5;i++)
{
progress +=50;
h.post(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
pgr.setProgress(progress);
if(progress==pgr.getMax())
{
//pgr.setVisibility(4);
Intent in= new Intent(getApplicationContext(),Home.class);
startActivity(in);
}
}
});
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO: handle exception
}
}
}
}).start();
}
}

The simplest solution would be the use of CountDown timer,
like,
below code would change activity after 10 sec and also change image after every 1 sec (change it according to your login). int variable i to keep track of image changing number.
int i = 0;
new CountDownTimer(10000, 1000) {
public void onTick(long millisUntilFinished) {
i++;
if(i == 1){
imageview.setImageResource(R.drawable.image1);
}
else if(i == 2){
imageview.setImageResource(R.drawable.image2);
}
else if(i == 3){
imageview.setImageResource(R.drawable.image3);
}
//and so on..........................
}
public void onFinish() {
//finish your splash screen activity
SplashActivity.this.finish();
}
}.start();

Android update TextView inside dialog in runOnUiThread

I have been spending couple hours to try to update the textview inside the dialog, but failed.
When the option is clicked, there are new dialog is shown, and inside the dialog, there are textviews and button, when I click the button, the textview will be update.
Here is the code related to the button onClick listener:
start.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
for (int i = 0; i < 50 ; i ++){
final String currentNum = String.valueOf(i + 1);
Thread t = new Thread() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(currentNum); //it is fine
currentNum.setText(currentNum); //it is the problem, the setText only work when the for loop is finished.
}
});
}
};
t.start();
}
}
});
Please let me know if you need more information. Thanks a lot in advance!
//it is a optionmenu
case R.id.action_refresh:
final TextView currentNum;
final ImageButton start;
String currentNum = Integer.toString(songList.size());
final Dialog lyricsAnalysis = new Dialog(this,R.style.cust_dialog);
lyricsAnalysis.requestWindowFeature(Window.FEATURE_NO_TITLE);
lyricsAnalysis.setContentView(R.layout.analysis);
lyricsAnalysis.setCancelable(true); //back button to cancel
lyricsAnalysis.setCanceledOnTouchOutside(true);
start = (ImageButton) lyricsAnalysis.findViewById(R.id.start);
//first value
currentNum.setText(String.valueOf(currentNum));
start.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
for (int i = 0; i < 50 ; i ++){
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
updateTextView(lyricsAnalysis,i);
}
}
});
lyricsAnalysis.show();
lyricsAnalysis.getWindow().setLayout(600, 1000);
break;
}
return super.onOptionsItemSelected(item); }
public void updateTextView(Dialog dialog, int i) {
final TextView currentNum = (TextView) dialog.findViewById(R.id.currentNum);
currentNum.setText(Stri`enter code here`ng.valueOf(i));
//return;
}

Try this method. This may helps you. It's work for me.(But I am not use this in dialog)
public void updateTextView(String toThis) {
TextView textView = (TextView) findViewById(R.id.textView);
textView.setText(toThis);
//return;
}

try like this
int elapsedtime=0;
boolean isTimerRunning=false;
Timer timerr;
inside onCreate
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//declare your textview here;
timerr=new Timer();
startTimer();
}
/*
* timer for displaying message bubble
*/
protected static void startTimer() {
isTimerRunning = true;
elapsedtime = 0;
// recordingseek.setProgress(0);
timerr.scheduleAtFixedRate(new TimerTask() {
public void run() {
// increase every sec
elapsedtime++;
mmHandler.obtainMessage(1).sendToTarget();
System.out.println("recording time" + elapsedtime);
if(elapsedtime==50)
timerr.cancel();
}
}, 1000, 2000);
};
public static Handler mmHandler = new Handler() {
public void handleMessage(Message msg) {
textview.setText(elapsedtime);
}
};
}
};

First android application not working..Help needed

Hey i recently got into android and made my first app which was meant to start a run down timer of 60 seconds when the user pressed start button. The application sets the content view fine and displays 60 but when i click the start button it displays 59 successfully and then the app crashes.Here's the code(it has only one activity)
public class test1activity extends Activity
{
Thread countdown;
long f, pa, jee;
TextView ytvp;
String s;
TextView uyti;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ytvp = (TextView) findViewById(R.id.textView2);
uyti = (TextView) findViewById(R.id.tv2);
countdown = new Thread() {
public void run() {
jee = (System.currentTimeMillis()) / 1000;
while ((((System.currentTimeMillis()) / 1000) - jee) < 60)
{
try {
sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
f = ((System.currentTimeMillis()) / 1000) - jee;
pa = 60 - f;
s = String.valueOf(pa);
ytvp.setText(s);
}
}
}
};
}
public void whenclickstart(View view) {
countdown.start();
}

You cannot set UI elements from inside another thread(Non UI thread). So you cannot use this below line.
ytvp.setText(s);
Try something like this, you dont need threading for what you are trying to do
new CountDownTimer(60000, 1000) {
public void onTick(long millisUntilFinished) {
ytvp.setText("" + millisUntilFinished/1000);
}
public void onFinish() {
ytvp.setText(""+0);
}
}.start();
If you do not want to use countdowntimer replace setText with
runOnUiThread(new Runnable() {
public void run() {
ytvp.setText(s);
}
});

Alert dialog does not appear

I have an application in which when the user starts the application a timer starts. After 10sec an AlertDialog pops up saying only 15 seconds reaming and displays a timer, and after 14 seconds it disappears. This works fine when on the first activity of the application. If the user passes from first Activty --> TimedNotify Activity the timer stops after 10seconds. onUserInteraction() in TimedNotify the timer restarts and works absolutely fine. Please assist me as to where I am going wrong.
public class FirstActivity extends TimedNotify{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.timercheck);
final Button btnstart2 = (Button) findViewById(R.id.btn);
btnstart2.setOnClickListener( new OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(FirstActivity.this,
TimedNotify.class);
startActivity(intent);
}
});
}
}
public class TimedAlert extends Activity
{
static CountDownTimer timer1, timer2;
int flag = 0;
protected static final String TAG = null;
public static AlertDialog alert, alertdialog;
private static Context context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final TextView mCounter1TextField = (TextView) findViewById (R.id.mCounter1TextField);
// first timer set for 10sec
timer1 = new CountDownTimer(10000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
Log.v(TAG, "timer1 ticking");
mCounter1TextField.setText("Seconds left: "
+ formatTime(millisUntilFinished));
}
public void onFinish() {
//after 10sec display alert box and show timer
Log.v(TAG, "timer1 finished");
timer1.cancel();
AlertDialog.Builder builder = new AlertDialog.Builder(
TimedAlert.this);
builder.setTitle("Session Time Out");
builder.setMessage("00:15");
builder.setPositiveButton("Resume", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog2,int iwhich)
{
Intent in = new Intent(TimedAlert.this,FirstActivity.class);
//in case there are many events ..the intent should be passed to the last activity on clicking resume
in.setAction(Intent.ACTION_MAIN);
in.addCategory(Intent.CATEGORY_LAUNCHER);
onUserInteraction();
}
});
builder.setNegativeButton ("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog2,int iwhich)
{
timer2.cancel();
timer1.start();
}
});
alert = builder.create();
alert.show();
timer2 = new CountDownTimer(15000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
Log.v(TAG, "timer2 ticking");
alert.setMessage("Your Session will expire in 5 minutes . Timleft00:"+ (millisUntilFinished / 1000));
mCounter1TextField.setText("Seconds left: "+ formatTime (millisUntilFinished));
}
//after 15 sec dismiss alert box
public void onFinish() {
Log.v(TAG, "timer2 finished");
timer2.cancel();
alert.dismiss();
}
}.start();
}
}.start();
}
#Override
public void onBackPressed() {
Intent in = new Intent(TimedAlert.this, FirstActivity.class);
startActivity(in);
}
public String formatTime(long millis) {
String output = "00:00";
long seconds = millis / 1000;
long minutes = seconds / 60;
seconds = seconds % 60;
minutes = minutes % 60;
String secondsD = String.valueOf(seconds);
String minutesD = String.valueOf(minutes);
if (seconds < 10)
secondsD = "0" + seconds;
if (minutes < 10)
minutesD = "0" + minutes;
output = minutesD + " : " + secondsD;
return output;
}
public void onUserInteraction() {
super.onUserInteraction();
// Remove any previous callback
try {
Log.v(TAG, "user interacted");
timer1.start();
timer2.cancel();
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
Log.v(TAG, "paused");
onUserInteraction();
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Log.v(TAG, "resumed");
onUserInteraction();
}
private void handleIntent(Intent intent) {
timer1.start();
}
#Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
Log.v(TAG, "stopped");
timer1.start();
}
#Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
Log.v(TAG, "started");
timer1.start();
}
}

OK, here are a few things I noted that might help you out:
public void onClick(DialogInterface dialog2, int iwhich) {
Intent in = new Intent(TimedAlert.this,
FirstActivity.class);
in.setAction(Intent.ACTION_MAIN);
in.addCategory(Intent.CATEGORY_LAUNCHER);
onUserInteraction();
}
You don't have a startActivity(in); after setting up all the parameters.
Why do onPause() and onResume() call onUserInteraction(), but onStart() and onStop() don't?
In fact, you should choose whether to use onPause() and onResume() only or onStart() and onStop(). Furthermore, onPause() or onStop() shouldn't restart the timers?
Thinking further about your reported problem, you say that it is when you are on your second activity that you have problems. Check out the lifecycle of an Activity - I suspect what might be happening is that you launch a new instance of your activity. Try setting your manifest to use android:launch mode="singleTask" for your activity.

Countdown timer with pause and resume

I want to do countdown timer with pause and restart.Now i am displaying countdown timer By implenting ontick() and onfinish().please help me out.HEre is th code for countdown timer
final CountDownTimer Counter1 = new CountDownTimer(timervalue1 , 1000)
{
public void onTick(long millisUntilFinished)
{
System.out.println("onTick method!"(String.valueOf(millisUntilFinished/1000)));long s1=millisUntilFinished;
}
public void onFinish()
{
System.out.println("Finished!");
}
}

in onTick method..save the milliseconds left
long s1=millisUntilFinished;
when you want to pause the timer use..
Counter.cancel();
when you want to resume create a new countdowntimer with left milliseconds..
timervalue=s1
counter= new Counter1();
counter.start();
See this link

I would add something to the onTick handler to save the progress of the timer in your class (number of milliseconds left).
In the onPause() method for the activity call cancel() on the timer.
In the onResume() method for the activity create a new timer with the saved number of milliseconds left.
Refer the below links

My first answer on stackOverFlow, hope it should help :) ...
This is how I solved the problem, control timer from Fragment, Bottomsheet, Service, Dialog as per your requirement, keep a static boolean variable to control.
declare in your Activity:
long presetTime, runningTime;
Handler mHandler =new Handler();
Runnable countDownRunnable;
Toast toastObj;
public static boolean shouldTimerRun = true;
TextView counterTv;
In onCreate:
presetTime =60000L;
runningTime= presetTime;
//setting up Timer
countDownRunnable=new Runnable() {
#Override
public void run() {
if (shouldTimerRun) //if false, it runs but skips counting
{
counterTv.setText(simplifyTimeInMillis(runningTime));
if (runningTime==0) {
deployToast("Task Completed"); //show toast on task completion
}
runningTime -= 1000;
presetTime = runningTime; //to resume the timer from last position
}
mHandler.postDelayed(countDownRunnable,1000); //simulating on-tick
}
};
mHandler.post(countDownRunnable); // Start our CountdownTimer
Now, whenever you want to pause the timer change the value of shouldTimerRun false and to resume make it true.
#Override
public void onResume() {
super.onResume();
shouldTimerRun=true;
}
#Override
public void onPause() {
super.onPause();
shouldTimerRun=false;
deployToast("Timer is paused !!");
}
Helping methods: (can be skipped)
public static String simplifyTimeInMillis(long time) {
String result="";
long difference = time;
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
if (difference<1000){
return "0";
}
if (difference>=3600000) {
result = result + String.valueOf(difference / hoursInMilli) + "hr ";
difference = difference % hoursInMilli;
}
if (difference>=60000) {
result = result + String.valueOf(difference / minutesInMilli) + "m ";
difference = difference % minutesInMilli;
}
if (difference>=1000){
result = result + String.valueOf(difference / secondsInMilli) + "s";
}
return result;
}
public void deployToast(String msg){
if (toastObj!=null)
toastObj.cancel();
toastObj = Toast.makeText(mContext,msg,Toast.LENGTH_SHORT);
toastObj.show();
}

I'm using two private vars in this case:
private long startPauseTime;
private long pauseTime = 0L;
public void pause() {
startPauseTime = System.currentTimeMillis();
}
public void resumen(){
pauseTime += System.currentTimeMillis() - startPauseTime;
}

I am afraid that it is not possible to pause or stop CountDownTimer and pausing or stopping in onTick has no effect whatsoever user TimerTask instead.
Set up the TimerTask
class UpdateTimeTask extends TimerTask {
public void run() {
long millis = System.currentTimeMillis() - startTime;
int seconds = (int) (millis / 1000);
int minutes = seconds / 60;
seconds = seconds % 60;
timeLabel.setText(String.format("%d:%02d", minutes, seconds));
}
}
if(startTime == 0L) {
startTime = evt.getWhen();
timer = new Timer();
timer.schedule(new UpdateTimeTask(), 100, 200);
}
You can add event listener's like this..
private Handler mHandler = new Handler();
...
OnClickListener mStartListener = new OnClickListener() {
public void onClick(View v) {
if (mStartTime == 0L) {
mStartTime = System.currentTimeMillis();
mHandler.removeCallbacks(mUpdateTimeTask);
mHandler.postDelayed(mUpdateTimeTask, 100);
}
}
};
OnClickListener mStopListener = new OnClickListener() {
public void onClick(View v) {
mHandler.removeCallbacks(mUpdateTimeTask);
}
};
For more refer to Android Documentation.

//This timer will show min:sec format and can be paused and resumed
public class YourClass extends Activity{
TextView timer;
CountDownTimer ct;
long c = 150000; // 2min:30sec Timer
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.YourXmlLayout);
timer = (TextView)findViewById(R.id.Yourtimer)
startTimer(); // it will start the timer
}
public void startTimer(){
ct = new CountDownTimer(c,1000) {
#Override
public void onTick(long millisUntilFinished) {
// Code to show the timer in min:sec form
// Here timer is a TextView so
timer.setText(""+String.format("%02d:%02d",millisUntilFinished/60000,(millisUntilFinished/1000)%60));
c = millisUntilFinished; // it will store millisLeft
}
#Override
public void onFinish() {
//your code here
}
};
ct.start();
}
/*===========================================================
*after creating this you can pause this by typing ct.cancel()
*and resume by typing startTimer()*/

public class MainActivity extends AppCompatActivity {
TextView textView;
CountDownTimer ctimer;
boolean runCountDown;
private long leftTime;
private static final long MILL_IN_FUTURE = 6000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = findViewById(R.id.text_view);
textView.setText("Click to start");
textView.setOnClickListener(this::clickStartAndPauseAndResume);
leftTime = MILL_IN_FUTURE;
}
public void clickStartAndPauseAndResume(View view) {
if (!runCountDown) {
long time = (leftTime == 0 || leftTime == MILL_IN_FUTURE) ? MILL_IN_FUTURE : leftTime;
ctimer = new CountDownTimer(time, 1) {
#Override
public void onTick(long l) {
leftTime = l;
textView.setText(l + "ms");
}
#Override
public void onFinish() {
textView.setText("Done");
leftTime = 0;
runCountDown = false;
textView.postDelayed(new Runnable() {
#Override
public void run() {
textView.setText("Click to start");
}
}, 1000);
}
}.start();
runCountDown = true;
} else {
ctimer.cancel();
textView.setText(textView.getText() + "\n Click to resume");
runCountDown = false;
}
}
}

A nice and simple way to create a Pause/Resume for your CountDownTimer is to create a separate method for your timer start, pause and resume as follows:
public void timerStart(long timeLengthMilli) {
timer = new CountDownTimer(timeLengthMilli, 1000) {
#Override
public void onTick(long milliTillFinish) {
milliLeft=milliTillFinish;
min = (milliTillFinish/(1000*60));
sec = ((milliTillFinish/1000)-min*60);
clock.setText(Long.toString(min)+":"+Long.toString(sec));
Log.i("Tick", "Tock");
}
The timerStart has a long parameter as it will be reused by the resume() method below. Remember to store your milliTillFinished (above as milliLeft) so that you may send it through in your resume() method. Pause and resume methods below respectively:
public void timerPause() {
timer.cancel();
}
private void timerResume() {
Log.i("min", Long.toString(min));
Log.i("Sec", Long.toString(sec));
timerStart(milliLeft);
}
Here is the code for the button FYI:
startPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(startPause.getText().equals("Start")){
Log.i("Started", startPause.getText().toString());
startPause.setText("Pause");
timerStart(15*1000);
} else if (startPause.getText().equals("Pause")){
Log.i("Paused", startPause.getText().toString());
startPause.setText("Resume");
timerPause();
} else if (startPause.getText().equals("Resume")){
startPause.setText("Pause");
timerResume();
}
