Stop Watch doesn't work in background mode - android

I have a stop watch, it work right, but when i press home button or button closing bell and reopen it after some time, I see wrong time in my stop watch. Tell me please what I can do to solve this problem ?

How to stop the running timer with EditText?

I'm trying to create an app that shows some questions and EditText fields in front of the each of the question for an answer with CountDownTimer, the problem I have is I'm trying to stop the running CountDownTimer on the last entered answer and save those seconds next to user's name but not sure how? I know questionTimer.cancel() would stop the timer but it has to be done on the last entered answer in last EditText.
This is the MainActivity.java file:
public class MainActivity extends AppCompatActivity {
CountDownTimer questionTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnStart = (Button) findViewById(R.id.start);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setQuestions();
timer();
}
});
}//End of create()
public void timer() {
questionTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
timer = (TextView) findViewById(R.id.timer);
timer.setText("Seconds Remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
timer.setText("Done!");
}
}.start();
}
public void setQuestions() {
ArrayList<Questions> qArrList = new ArrayList<>();
for (int i = 0; i < 5; i++) {
ques = new Questions();
ques.setQuestion("");
qArrList.add(ques);
}
adapter = new AdapterListView(getBaseContext(), R.layout.item_listview, qArrList);
questListView.setAdapter(adapter);
}
}//End of Class
This is the AdapterListView.java file:
public class AdapterListView extends ArrayAdapter<Questions> {
Context mContext;

private ArrayList<Questions> questionsArrayList;
private Questions quesObject;
private ArrayList<String> quesList = new ArrayList<String>();

I have manged to sort this out by setting an int variable against Position and calling this in MainActivity class inside the running Timer. Please see the code below.

timer = (TextView) findViewById(R.id.timer);
timer.setText("Seconds Remaining: " + millisUntilFinished / 1000);

questionTimer.cancel();
}

You had the Collections.shuffle() part right, you just need to get the randomized list back into your array:
private Integer[][] img_mc = new Integer [16][2];
...
List<Integer[]> img_mc_list = new ArrayList<Integer[]>();
for (Integer[] img : img_mc) {
img_mc_list.add(img);
}
Collections.shuffle(img_mc_list);
img_mc_list.toArray(img_mc);
Or use this:
private void randomize(Integer[][] array) {
int index;
Integer[] temp;
Random random = new Random();
for (int i = array.length - 1; i > 0; i--) {
index = random.nextInt(i + 1);
temp = array[index];
array[index] = array[i];
array[i] = temp;
}
}

Android playing video fullscreen in a new activity on button click

I'm streaming a video in my app, and it works fine.
The problem is that when I try to make it full screen (in a new activity or otherwise), the screen is blank.
I have tried doing it without starting a new activity, as suggested here:
In my main activity:
butFullScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(isFS)
setContentView(R.layout.activity_full_screen_video);
else
setContentView(R.layout.activity_starting_point);
}
});
I've also tried opening it in a new activity (which I prefer):
butFullScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Start fs intent
Intent myIntent = new Intent(StartingPoint.this, FullScreenVideo.class);
StartingPoint.this.startActivity(myIntent);
}
});
Where FullScreenVideo:
public class FullScreenVideo extends StartingPoint{
//private VideoView vv;
public FullScreenVideo(){
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.activity_full_screen_video);
vv.start();
}
}
And activity_full_screen_video:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:background="#ff000000">
<VideoView
android:id="#+id/vv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
And in my manifest:
<activity
android:name=".FullScreenVideo"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:configChanges="keyboardHidden|orientation|screenSize" />
It doesn't show any error or crash, just a blank screen. Also, I'm not using the media controller, so answers without that would be appreciated :)

My activity won't pause when dialog is shown

I have been working on application that displays a problem and 4 possible answers. Answer correctly, and the next problem appears. A wrong answer or letting the timer run out results in a popup that tells the correct answer and that you just lost a "life". Everything works well except that when the popup appears, the countdown timer continues and generates another popup. I can't find a way to get the activity to wait for the button on the dialog to be pressed before continuing to the next problem. I have read many questions/answers here and combed through many pages on the android developers site. Any help with this problem would be greatly appreciated.

You have a repetitive loop insisde a timer...
Let say, when your timer is is finished, it will call onFinish() and you are calling doWrong() in onFinish(). and doWrong() is calling doPopUp() which will open a Dialog again.(repetitively). To avoid, maintain some flags(like boolean or int) and based on the value of the flag, you decide whether to show PopUp Dialog when timer is finished or cancel the Timer when you are dismissing Diaog...

private void doWrong() {
Log.v("Events", "DoWrong");
counter.cancel();
soundwrong.start();
lives = lives - 1;
if (lives != 5) {
if (lives == 4) {
lf5.setVisibility(View.INVISIBLE);

nolives = true;

} else {

}
l2 = getResources().getString(R.string.LifeLost);
l3 = getResources().getString(R.string.CorrAnswer)+" "+corrAnswer;
}
// change here
if(!timeup)
doPopup();

Thanks to all that provide help on this site. I have gained much knowledge here.

Displaying an array of values to buttons

I have an array of 12 values and I want to display it one after the other. Initially on application run I am displaying 6 values. On the button click I want to display the other 6 values one by one.
prevbutton-> value1 value2 value3 value4 value5 value6 -> nextbutton
So on next button click it should be like this.
prevbutton-> value2 value3 value4 value5 value6 value7 -> nextbutton
This should be continued up to the 12 values, and the reverse should happen in case of prevbutton.
I have used this code but it's not working:
public void onClick(View v) {
switch (v.getId()) {
case R.id.radionextstn:
forwardtune();
break;
}
}
public void forwardtune(){
Button[] buttons = new Button[5];
buttons[0] = (Button)findViewById(R.id.radiostation1);
buttons[1] = (Button)findViewById(R.id.radiostation2);
buttons[2] = (Button)findViewById(R.id.radiostation3);
buttons[3] = (Button)findViewById(R.id.radiostation4);
buttons[4] = (Button)findViewById(R.id.radiostation5);
buttons[5] = (Button)findViewById(R.id.radiostation6);
if(currentlyDisplayingFromPosition + 6 >= arraySize)
return;
for(int i=0; i<arraySize; i++) {
buttons[i].setText("");
}
for(int i=currentlyDisplayingFromPosition; i<=currentlyDisplayingFromPosition+6; i++){
if (frequency[i] == 0.0)
buttons[i].setText("");
else
buttons[i].setText("" + frequency[0]);
}
}
I am displaying the first 6 values like this:
public void autoTune() {
Log.i("autotune", " called");
if (frequency[0] == 0.0)
station1.setText(""); // station1 is a button
else
station1.setText("" + frequency[0]); // station1 is a button
if (frequency[1] == 0.0)
station2.setText(""); // station2 is a button
else
station2.setText("" + frequency[1]); // station2 is a button
if (frequency[2] == 0.0)
station3.setText(""); // station3 is a button
else
station3.setText("" + frequency[2]); // station3 is a button
if (frequency[3] == 0.0)
station4.setText(""); // station4 is a button
else
station4.setText("" + frequency[3]); // station4 is a button
if (frequency[4] == 0.0)
station5.setText(""); // station5 is a button
else
station5.setText("" + frequency[4]); // station5 is a button
if (frequency[5] == 0.0)
station6.setText(""); // station6 is a button
else
station6.setText("" + frequency[5]); // station6 is a button
}
#Override
protected Boolean doInBackground(Context... params) {
// TODO Auto-generated method stub
Log.i("in autotune", " before freq length");
int[] freq = { 911, 943, 947, 932, 901, 964, 843, 835, 946,904,908,873 };
freqCounter = 0;
Log.i("in autotune", "after freq length : " + freq.length);
frequency = new double[freq.length];
Log.i("in autotune", "after frequency length : " + frequency.length);
for (int k = 0; k < freq.length; k++) {
Log.i("In Radio.java", "Freq : " + freq[k]);
frequency[k] = freq[k];
frequency[k] = frequency[k] / 10;
if (frequency[k] == 0.0)
break;
freqCounter++;
Log.i("In Radio.java", "Frequency : " + frequency[k]);
}
}

first error I see, you declare an array of 5 button and try to put 6 buttons :
Button[] buttons = new Button[5];
you should do:
Button[] buttons = new Button[6];

solution :
if(currentlyDisplayingFromPosition + 6 >= arraySize)
return;
for(int i=0; i<6; i++){
buttons[i].setText("" + frequency[currentlyDisplayingFromPosition+i]);
}

Modify it as per your need.
Button[] btns = new Button[8];
List<String> pages = new ArrayList<String>();
int mStart = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dialog_activiy);
btns[0] = (Button) findViewById(R.id.pr);
btns[1] = (Button) findViewById(R.id.b1);
btns[2] = (Button) findViewById(R.id.b2);
btns[3] = (Button) findViewById(R.id.b3);
btns[4] = (Button) findViewById(R.id.b4);
btns[5] = (Button) findViewById(R.id.b5);
btns[6] = (Button) findViewById(R.id.b6);
btns[7] = (Button) findViewById(R.id.nt);
btns[0].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
rearrangeBy(-1);
}
});
btns[btns.length - 1].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
rearrangeBy(1);
}
});
// setup listeners
for (int i = 1; i < btns.length - 1; i++) {
btns[i].setOnClickListener(mClickListener);
}
for (int i = 0; i < 12; i++) {
pages.add((i + 1) + "");
}
setUpButtons();
}
final View.OnClickListener mClickListener = new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(DialogActiviy.this, v.getTag() + "",
Toast.LENGTH_SHORT).show();
}
};
private void rearrangeBy(int by) {
mStart += by;
setUpButtons();
}
private void setUpButtons() {
// setup previous button
btns[0].setEnabled(!(mStart == 1));
// setup next button
int end = pages.size() - btns.length + 2 + 1;
btns[btns.length - 1].setEnabled(!(mStart == end));
// setup intermediate buttons
for (int i = 1; i < btns.length - 1; i++) {
String text = (mStart + i - 1) + "";
btns[i].setText(text);
btns[i].setTag(text);
}
}
