How to make a countdown timer repeat

How to make a countdown timer repeat - java

It is my first time working with Android Studio and my Java skills are basically non-existent so I need a little help with a project I am working on.
I need to make a timer that repeats after a certain break. The user should decide how many times should timer repeat and what is the duration of break.
So far I did the standard countdown timer but no matter what i try i can't make it repeat
That is the working code I have so far

Functionality
public class MainActivity extends AppCompatActivity {
EditText editTextSession;
EditText editTextBreak;
EditText editTextRepeats;
Button buttonStart;
TextView textViewTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editTextSession =(EditText) findViewById(R.id.editTextSession);
editTextBreak =(EditText) findViewById(R.id.editTextBreak);
editTextRepeats =(EditText) findViewById(R.id.editTextRepeats);
buttonStart =(Button) findViewById(R.id.buttonStart);
textViewTimer =(TextView) findViewById(R.id.textViewTimer);
buttonStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String text = editTextSession.getText().toString();
int seconds = Integer.valueOf(editTextSession.getText().toString());
CountDownTimer countDownTimer = new CountDownTimer(seconds * 1000, 1000) {
#Override
public void onTick(long millis) {
textViewTimer.setText("time:" + (int) (millis / 1000));
}
#Override
public void onFinish() {
extViewTimer.setText("Finished!");
}
}.start();
}
}
);

Did You try Integer.parseInt(String value) instead of Integer.valueOf(String value)? Maybe it will make a diffrence. You can add an exception if someone type wrong value.

if you're looking for another way to create timer, you can do something like this with Runnable() :
private TextView timeCounterTextView;
private int smsTimeOut = 10; // 10 SECONDS
private Runnable timeCounterRunnable = new Runnable() {
#Override
public void run() {
if (smsTimeOut == 1) {
//Do whatever when timeout
}
smsTimeOut--;
timeCounterTextView.setText(String.valueOf(smsTimeOut));
handler.postDelayed(this, 1000);
}
};
and whenever you want to start countdown initialize and start timer with init() method like below :
private void init(){
handler.removeCallbacks(timeCounterRunnable);
smsTimeOut = 10;
handler = new Handler();
handler.post(timeCounterRunnable);
}
anytime you want to repeat you can call init() again.
hope this helps.

Use this
timer.start();
And stop it with:
timer.cancel();
Example:
String text = editTextSession.getText().toString();
int seconds = Integer.valueOf(text);
//get how many repeat
String repeatText = editTextSession.getText().toString();
int repeat = Integer.valueOf(repeatText);
int count= 0;
CountDownTimer countDownTimer = new CountDownTimer(seconds * 1000, 1000) {
#Override
public void onTick(long millis) {
textViewTimer.setText("time:" + (int)(millis / 1000));
}
#Override
public void onFinish() {
extViewTimer.setText("Finished!");
count++;
//check if count still less than repeat number
if(count < repeat){
Runnable r = new Runnable() {
public void run() {
countDownTimer.start();
}};
new Handler().postDelayed(r,2000); //delay repeat timer 2 seconds
}
else{
countDownTimer.cancel();
count = 0;
}
}
}.start();

New on coding: How can I make that if the radioButton is not checked it says it's not so you cant complete the process of creating an object:

So I have an object with some fields (Two edit text and a radiogroup with two radiobuttons) and I need them all to be completed to create the object, I have all done except the gender (masculino-femenino down boolean down there coming from a from radiobutton). Everything works but the radioButton, How can I know they're empty, I'm running out of logic ideas and I know it have to ve something easy for this, probably obious This is what I have:
```
public boolean camposCompletos() {
if (nombre.isEmpty()) {
return false;
} else if (desc.isEmpty()) {
return false;
}else if (masculino.isChecked() || femenino.isChecked()) {
sexo_comprobacion = false;
return false;
}
return true;
}
```

Try with following code it will help you.

How to run timer one after another in android?

How to run timer one after another?
for eg: I am using two edittext and one button,
after giving input to 2 edittext as 1 and 2(in minutes), the timer should first complete the first given input and then to start the 2nd input.
Then when i click stop timer, it should stop and display the edittext input and the stopped timer value.
but it's working only for 1st input..but fails in second input.
Here is the code which I tried.
public class MainActivity extends Activity implements OnClickListener {
private Button buttonStartTime, buttonStopTime;

private CountDownTimer countDownTimer1; // built in android class
// CountDownTimer

Android Progress Bar not working

I have made a progress bar in Android but it is not at all working. What am I doing wrong? I have just started to learn android. Below is my code.
MainActivity.java-
public class MainActivity extends AppCompatActivity {
ProgressBar progressBar;
int mporgress=0;
EditText time;
private Handler mHandler = new Handler();
private static final int PROGRESS = 0x1;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void Startbuttononclick(View view){
Button startbutton=(Button) findViewById(R.id.button);
startbutton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
mporgress = Integer.parseInt(time.getText().toString());
progressBar.setProgress(mporgress);
new Thread(new Runnable() {
public void run() {
while (mporgress < 100) {
// Update the progress bar
mHandler.post(new Runnable() {
public void run() {
progressBar.setProgress(mporgress);
mporgress = doWork();
try{
Thread.sleep(1000);
}catch (InterruptedException e){}
}
});
}
}
}).start();
}
});
}
public void doprogress(View view) {
}
public int doWork(){
mporgress++;
return mporgress;

Check out this image below-
- https://i.stack.imgur.com/2TBIb.png
Note- Enter the time in this image is an EditText with a hint and not a TextView.
It is appearing but not working.
I have done these changes so far.-
https://i.stack.imgur.com/UujpB.png
But still the progress bar is still continuously rotating.

Seems you forgot to initialize EditText -time and ProgressBar. Init it inside onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
progressBar =(ProgressBar) findViewById(R.id.progressBar4);
time = (EditText) findViewById(R.id.editText); //here
}
Also inside button click the bar:
progressBar = new ProgressBar(this);
mporgress = Integer.parseInt(time.getText().toString());

Optimizing layout/bitmaps/database with ASYNC or another thread?

As a beginner I have some questions about optimizing my application speed. I'm building a simple quiz app there I have an sqlite database inside with some information. With that information I'm generating my questions in quiz page.
It was working pretty fine and fast until I fixed some buttons/background in sketch and use them. Now it's working much more slower and I'm getting error messages at logcat like "Skipped xxx frames! The application may be doing too much work on its main thread." I have searched on google for a while and found out that the bitmaps are slowing down my application. Have read about async and using a new thread to make it run faster.
As a solution I have resized some of my bitmaps, but then I'm getting less quality in my design, so I decided to fix it. I have googled some more about loading my layout with async or a new thread but didn't really find out how/where to do it. What makes me confused is that I don't know if it's to load layout with a new thread is the best solution or to load other processes with new thread. Need some recommendation about how to optimize my app. Here is my code, at least the quiz page that is slowest. I'm not really sure what to optimize there with a new thread. Under a question it's just countdowntimer that is running, and when next clicked countdowntimer starts over and the gui updates with the new question.
My quizpage code:
public class QuizPage extends ActionBarActivity

I don't think it has much to do with bitmaps, especially if you are pulling them from Drawable resources. The source of your lag is likely your database queries, which are happening in onCreate, which are blocking the main thread to do disk access. Instead, use a CursorLoader as described in https://developer.android.com/training/load-data-background/setup-loader.html

handling too many requests of animation on the main ui thread from other threads - android

I am working on creating activity that has too many animations, and when starting this activity the logcat shows me this message again and again during the life time of this activity:
I/Choreographer﹕ Skipped 36 frames! The application may be doing too much work on its main thread.
so I did many stuff in another threads, but still there is heavy access on the main UI thread. as well as, the animation is becoming really slow on some high resolution devices
what can be possible solution for handling this problem ?
UPDATED: added code
so here is the code of showing the views(which are 6 imageButtons),
private void setupAnimationForAllViews(ArrayList<View> listOfViews,
int animationId,
final boolean isAppearing) {
int startDelay = mDelay; // milliseconds
int numberOfViews = listOfViews.size();
for (int i = 0; i < numberOfViews; i++) {
final Animation animator = AnimationUtils.loadAnimation(mContext, animationId);
animator.setStartOffset(startDelay);
startDelay += mOffSet; // every view will start after 100 milliseconds from the other
final View currentView = listOfViews.get(i);
final int indexOfCurrentCheckedItem = i;
mMainUIThreadHandler.post(new Runnable() {
#Override
public void run() {
currentView.startAnimation(animator);
}
});
}
}
I trigger it in seperated thread like this:
new Thread(new Runnable() {
#Override
public void run() {
setupAnimationForAllViews(tempListOfViews,
animationId, isAppearing);
}
}).start();
In the same activity i have Ken Burns View, which implement ken burns effect on 2 images, The code of this kenBurnsView is in this link: KenBurnsView

This is the main activity java part:
public class MainActivity extends Activity {
//Buttons in the MainActivity
AnimationHelper animationHelper;

private final int hideOnClickAnimation = R.anim.fade_out;
private final int displayAnimation = R.anim.test_anim;
//For Kenburns View with multible images
private KenBurnsView mKenBurnsView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUI();
initAnimation();
init();
// for testing, we may put those in initAnimation()
animationHelper.setDelay(100);
animationHelper.setOffSet(50);
mKenBurnsView.setResourceIds(R.drawable.test16, R.drawable.uphill2);
}
private void initAnimation() {
//Adding OnClickListeners to the Buttons in the MainActivity - End
// The order is important here
listOfButtons = new ArrayList<>();
listOfButtons.add(btnGroupSirketleri);
listOfButtons.add(btnGale);
listOfButtons.add(btnSektorelFaa);
listOfButtons.add(btnKur);
listOfButtons.add(btnInsanKayna);
listOfButtons.add(btnIlet);
// Adding Animation
animationHelper = new AnimationHelper(listOfButtons, this, mUIThreadHandler);
}
private void initUI() {
//initializing the buttons in the mainactivity
btnKur = (ImageView) findViewById(R.id.btnKur);
btnGroup = (ImageView) findViewById(R.id.btnGroup);
btnSektorelFaa = (ImageView) findViewById(R.id.btnSektorelFaa);
btnInsanKayna = (ImageView) findViewById(R.id.btnInsanKayna);
btnGale = (ImageView) findViewById(R.id.btnGale);
btnIlet = (ImageView) findViewById(R.id.btnIlet);
// KenBurns View
mKenBurnsView = (KenBurnsView) findViewById(R.id.header_picture);
}
private void init() {
//Adding OnClickListeners to the Buttons in the MainActivity - Start
btnKur.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
btnGroup.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
btnSektorelFaa.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
btnInsanKayna.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
btnGale.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
btnIlet.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationHelper.hideViewsWithClickedView(hideOnClickAnimation, v);
}
});
}
#Override
protected void onResume() {
super.onResume();
animationHelper.displayViews(displayAnimation, new IDoOnEndOfWholeAnimation() {
#Override
public void doIt() {
if (!mKenBurnsView.isAnimating)
mKenBurnsView.startKenBurnsAnimation();
}
});
}
#Override
protected void onPause() {
super.onPause();
if (mKenBurnsView.isAnimating)
mKenBurnsView.stopKenBurnsAnimation();
}
}

I reduced the sizes and a little bit the resolution of images for Kenburns and the buttons backgrounds in order to get it working smoothly. Playing with threads did not solve the issue of lagging for me.

Did You try Integer.parseInt(String value) instead of Integer.valueOf(String value)? Maybe it will make a diffrence. You can add an exception if someone type wrong value.
