How to update progress bar max with changing values automatically?

I am working on a fitness app using Google fit API.
Step data from the API is passed to a method stepDisplayer with e.g. params (3300, "steps").
I am trying to update the progress bar once value == daily1 so that the max of bar is then pbStepBar.setMax(daily2) and again to pbStepBar.setMax(daily3) when value == daily2, while the progress of the bar is always set to value e.g. 3500/4000 then 4102/8000 and 8900/12000.
I tried to use a switch statement comparing the goals to value with a method called setNextGoal(value) with getter and setter methods getCurrentGoal() and setCurrentGoal() as seen below, but that did not work. Max value does not change from daily1 when I run the application and it looks something like this 5050/4000.
What am I doing wrong? Can I replace pbStepBar with another progress bar and and switching visibility?
Layout
<ProgressBar
android:id="#+id/pbStepBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="300dp"
android:layout_height="15dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="5dp"
android:layout_marginTop="25dp"
android:indeterminate="false"
android:scaleY="3"
/>
public class MainActivity {
//these are goals
int daily1 = 4000
int daily2 = 8000
int daily3 = 12000
//set to this onCreate
pbStepBar.setMax = daily1
private void stepDisplayer(final int value, final String field) {
tvHomeSteps = (TextView) findViewById(R.id.tvHomeSteps);
pbStepBar = (ProgressBar) findViewById(R.id.pbStepBar);
setNextGoal(value);
runOnUiThread(new Runnable() {
#Override
public void run() {
tvHomeSteps.setText("today's " + field + " " + value + "/" + dailyStepGoal);
}
});
new Thread(new Runnable() {
#Override
public void run() {
while (value <= getCurrentGoal()) {
handler.post(new Runnable() {
#Override
public void run() {
pbStepBar.setProgress(value);
}
});
try {
Thread.sleep(25);
}
catch (InterruptedException e) {
e.printStackTrace();
}
if (getCurrentGoal() == value) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "Well done you reached your daily goal of " + getCurrentGoal() + " " + field,
Toast.LENGTH_LONG).show();
}
});
}
setNextGoal(value);
}
}
}).start();
}
private void setNextGoal (final int value) {
switch (value) {
case dailyStepGoal:
setCurrentGoal(dailyStepGoal + stepGoalIncrement);
pbStepBar.setMax(dailyStepGoal + stepGoalIncrement);
break;
case dailyStepGoal + stepGoalIncrement:
setCurrentGoal(dailyStepGoal + (stepGoalIncrement*2));
pbStepBar.setMax(dailyStepGoal + (stepGoalIncrement*2));
break;
case dailyStepGoal + (stepGoalIncrement*2):
setCurrentGoal(dailyStepGoal + (stepGoalIncrement*3));
pbStepBar.setMax(dailyStepGoal + (stepGoalIncrement*3));
break;
case dailyStepGoal + (stepGoalIncrement*3):
setCurrentGoal(dailyStepGoal + (stepGoalIncrement*4));
pbStepBar.setMax(dailyStepGoal + (stepGoalIncrement*4));
break;
case dailyStepGoal + (stepGoalIncrement*4):
setCurrentGoal(dailyStepGoal + (stepGoalIncrement*5));
pbStepBar.setMax(dailyStepGoal + (stepGoalIncrement*5));
break;
}
}

I found the solution.
I used an int variable currentGoal as seen below to keep track of the current goal. I think the problem was that I was trying to call methods in the activity from the UI thread. I used a simple if statement, don't know why I didn't think of this earlier.
I also tested the solution it works well.
private void stepDisplayer(final int value, final String field) {
runOnUiThread(new Runnable() {
#Override
public void run() {
if (value >= currentGoal) {
Toast.makeText(getApplicationContext(), "Well done you reached your daily goal of " + currentGoal + " " + field,
Toast.LENGTH_LONG).show();
currentGoal += stepGoalIncrement;
tvHomeSteps.setText("today's " + field + " " + value + "/" + currentGoal);
}
else {
tvHomeSteps.setText("today's " + field + " " + value + "/" + currentGoal);
}
}
});
new Thread(new Runnable() {
#Override
public void run() {
while (value <= currentGoal) {
handler.post(new Runnable() {
#Override
public void run() {
pbStepBar.setProgress(value);
if (value >= pbStepBar.getMax()) {
pbStepBar.setMax(currentGoal);
pbStepBar.setProgress(value);
}
else {
pbStepBar.setProgress(value);
}
}
});
try {
Thread.sleep(25);
}
catch (InterruptedException e) {
e.printStackTrace();
}
//setNextGoal(pbStepBar, value);
}
}
}).start();
}

Stop / Pause an Iterator

I am trying to implement an animation of Markers on a Google Map. The issue I am running into is an Animation being started while another Animation is still happening for a specific Marker.
Is there a way to stop the iteration of a loop, and continue only when
a certain criteria is met?
Get LatLng - Start Animation - Callback Fires (Animation Finished) - Get LatLng.. Etc.
public void animateMarker(final String key, final List<LatLng> latlngList) {
Log.e(TAG, "------------- MARKER " + key + "-------------");
Handler mHandler = new Handler();
mHandler.post(new Runnable() {
final AnimateCarObj animateCarObj = animateCarObjMap.get(key);
final Marker marker = markersHashMap.get(key);
Boolean isAnimationRunning = false;
#Override
public void run() {
final Iterator<LatLng> iterator = latlngList.iterator();
while (iterator.hasNext()) {
if (!(isAnimationRunning)) {
Log.e(TAG, "START -- " + key + ": " + iterator.next().toString());
try {
isAnimationRunning = true;
LatLngInterpolator latlonInter = new LinearFixed();
latlonInter.interpolate(1, marker.getPosition(), iterator.next());
MarkerAnimation.animateMarker(new RunningCallback() {
#Override
public void onFinish() {
Log.e(TAG, "FINISH -- " + key + ": " + iterator.next().toString());
isAnimationRunning = false;
}
}, latlngList.size(), marker, iterator.next(), latlonInter);
} catch (Exception e) {
Log.e(TAG, "EXCEPTION: " + e.getMessage());
e.printStackTrace();
}
}
}
}
});
}

Just use a while loop to stop your iterator logic.
while (iterator.hasNext()) {
// wait
while (!someBooleanConditionToWaitFor) { }
// do your other stuff
// when you're done your other stuff, set it back to false.
someBooleanConditionToWaitFor = false;
}
When your animation has finished, set the condition to true so that it continues. When you're at the end of that iteration, set it back to false so it waits again.

Create a global static boolean flag
public static boolean criteriaMet=false;
After your criteria is met set it to true. Continue the iteration of the loop only if the flag is true.

Save user input string to variable on button click

in my application the user will input a channel they want to subscribe to in an editable text field. Upon clicking the subscribe button, the variable that is placed in my method to subscribe the user should be updated to that of the users choice and then a toast will appear notifying the user that they are subscribed to this channel.
At the bottom, I get the string value that the user inputs in the EditText field, but I don't think I'm putting it in the right place. Can someone take a look at it and let me know what I'm doing wrong? Let me know if I wasn't clear or am missing something and I can try to explain better. Thanks!
public class MainActivity extends ActionBarActivity {
private Button channelSubscribeButton;
private EditText subscribeChannelEditText;
//Declare variable
String subscribeChannel = null;
//-------------------------Access PubNub API-------------------------//
Pubnub pubnub = new Pubnub("pub-c-940c4776-36ff-425f-9677-f1c904a9d57b", "sub-c-cf42b292-a8bf-11e4-85d5-0619f8945a4f");

String yourSubscribeChannel = "Subscribed to the " + subscribeChannel + " Channel";

return subscribeChannel;
}

Your subscribeChannel variable is only visible within the scope of your onChannelButtonClick method. Declare it outside along with your instance variables.
public void onChannelButtonClick(View view) {
//here you set it and then it's lost.
String subscribeChannel = String.valueOf(subscribeChannelEditText.getText());
String yourSubscribeChannel = "Subscribed to the " + subscribeChannel + " Channel";
Toast.makeText(this, yourSubscribeChannel, Toast.LENGTH_LONG).show();
}
Instead do:
//declare it.
String subscribeChannel = null;
And then on your method assign the value.
public void onChannelButtonClick(View view) {
//assign it.
subscribeChannel = String.valueOf(subscribeChannelEditText.getText());
String yourSubscribeChannel = "Subscribed to the " + subscribeChannel + " Channel";
Toast.makeText(this, yourSubscribeChannel, Toast.LENGTH_LONG).show();

Closed 5 years ago.
I've got this simple timer in my app which is runs in every 3 seconds.
It works perfectly if it's not in a fragment class.
But here in fragment I always got the error: Only the original thread that created a view hierarchy can touch its views.

This error occurs when trying to access UI elements from any thread that is not the UI thread.
To access/modify elements from a non-UI-thread, use runOnUIThread.
However as you need to change a UI element from within a fragment, runOnUIThread should be invoked onto the fragments owning activity. You can do this through getActivity().runOnUIThread().
EG:
timer.schedule(new TimerTask() {
#Override
public void run() {
// Your logic here...
// When you need to modify a UI element, do so on the UI thread.
// 'getActivity()' is required as this is being ran from a Fragment.
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
// This code will always run on the UI thread, therefore is safe to modify UI elements.
myTextBox.setText("my text");
}
});
}
}, 0, 3000); // End of your timer code.
For further information see the following documentation:
Android Fragments (specifically, getActivity()).
TimerTask.
Invoking a Runnable on the UI thread.

you need to use the runOnUIThread() function I have an example somwhere that I will post when I find it.
you need to give your timer an instance of MainActivity alternatively see this question I asked Android image timing issues with what sounds like a similar thing to what you were trying to do
public static void updateText(Activity act, resID)
{
loadingText = (TextView) activity.findViewById(R.id.loadingScreenTextView);
act.runOnUiThread(new Runnable()
{
public void run()
{
loadingText.setText(resID);
}
});
}

You are doing UI operation from another thread. I suggest you to use following.
runOnUiThread(new Runnable() {
#Override
public void run() {
kiir.setText(ki_adat);
}

2 solutions :
Use the View.post(Runnable) method
Use the Activity.post(Runnable) method
And put the myTextView.setText(str) call in the run() method of the Runnable object.

Try this:
textView.post(new Runnable() {
#Override
public void run() {
textView.setText("Hello!"); }
});

TRY THIS: put this part of code somewhere but not in activity onCreate method
public void LoadTable(final String u, final String k)
{
// runOnUiThread need to be used or error will appear
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
try {
runOnUiThread(new Runnable() {
#Override
public void run() {
//method which was problematic and was casing a problem
createTable(u, k);
}
});
} catch (Exception exception) {
createAndShowDialog(exception, "Error");
}
return null;
}
