Seekbar in android not scrolling on touch

Code Run with no errors. But seekbar not working. It is the center but not able to slide on touch.
timesTablesSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
int min =1;
int timesTableNumber;
if(i<1){
timesTableNumber = min;
}else{
timesTableNumber = i;
}
Log.i("Seekbar Value", Integer.toString(timesTableNumber));
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

On Drage Event Seekbar Reset with 0

I've implemented a list of seekbars. According to my functionality, I want the sum of all seekbar not to exceed 100% for example if I drag first seekbar to 60% the next one will not exceed 40%.
I have made it work but whenever I drag the first one to some value (let's say 60 %) and then the second one to let's say 40% and then again when I try to drag the first one to decrease its value resets to 0. What is the problem with my code?
holder.shelfShareSeekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
remainingShelfShare = 100 - shelfShareSum;
holder.percentTextView.setText(String.valueOf(progress));
productShelfShareMap.get(((Products)list.get(position)).getProductID());
if(progress > remainingShelfShare){
holder.shelfShareSeekbar.setProgress(remainingShelfShare);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
list.get(position).setSetSlider(seekBar.getProgress());
shelfShareSum = 0;
productShelfShareMap.put(((Products)list.get(position)).getProductID(), Integer.parseInt(holder.percentTextView.getText().toString()));
for (HashMap.Entry<Integer, Integer> entry : productShelfShareMap.entrySet()){
shelfShareSum += entry.getValue();
}
}
});

Use SetMax function of seekbar to setvalue in SecondSeekbar.
int step = 1; // set it accordingly if you want data in 3.1,3.2 range
int max = 100;
int min; // if you want to set min criteria too.
shelfShareSeekbar.setOnSeekBarChangeListener(
new OnSeekBarChangeListener()
{
#Override
public void onStopTrackingTouch(SeekBar seekBar) {}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {}
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser)
{
// Ex :
// And finally set value of next seekbar based on firstone
secondseekbar.setMax((max - progress) / step);
}
}
);

Android cyclic listeners

I've got a small issue in my code:
I've a SeekBar and an EditText in a layout.
What I want to do is to set the EditText value when the SeekBar changes and set the SeekBar progress when the EditText changes.
So far, I've the following code:
SeekBar seek_coagulation = (SeekBar) findViewById(R.id.seek_coagulation);
EditText edit_coagulation = (EditText) findViewById(R.id.edit_coagulation);
seek_coagulation.incrementProgressBy(1);
seek_coagulation.setMax(1000);
seek_coagulation.setOnSeekBarChangeListener( new OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
double value = progress / 100.0;
edit_coagulation.setText(String.valueOf(value));
}
public void onStartTrackingTouch(SeekBar seekBar)
{
}
public void onStopTrackingTouch(SeekBar seekBar)
{
}
});
edit_coagulation.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s)
{
double value = (s != null && s.toString().length() > 0) ? Double.parseDouble(s.toString().replace(',', '.')) : 0D;
int progress = (int) (value * 100);
seek_coagulation.setProgress(progress);
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int count)
{
}
});
The first case (SeekBar to EditText) works well, but not the second.
The problem is that it is a loop (SeekBar to EditText to SeekBar to EditText etc.).
Is there a way to fix that ?

I suggest to use two boolean parameters to lock changes, like this:
boolean mIsTextLocked = false;
boolean mIsSeekBarLocked = false;
seek_coagulation = (SeekBar) findViewById(R.id.seek_coagulation);
EditText edit_coagulation = (EditText) findViewById(R.id.edit_coagulation);
seek_coagulation.incrementProgressBy(1);
seek_coagulation.setMax(1000);
seek_coagulation.setOnSeekBarChangeListener( new OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
if(!mIsSeekBarLocked){
mIsTextLocked = true;
double value = progress / 100.0;
edit_coagulation.setText(String.valueOf(value));
}
}
public void onStartTrackingTouch(SeekBar seekBar)
{
}
public void onStopTrackingTouch(SeekBar seekBar)
{
mIsTextLocked = false;
}
});
edit_coagulation.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s)
{
if(!mIsTextLocked){
mIsSeekBarLocked = true;
double value = (s != null && s.toString().length() > 0) ?Double.parseDouble(s.toString().replace(',', '.')) : 0D;
int progress = (int) (value * 100);
seek_coagulation.setProgress(progress);
mIsSeekBarLocked = false;
}
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int count)
{
}
});
I haven't tested it but it should work.

How to change the scale of seekBar progress

I have made use of seekbar for other requirements, now I have having trouble with a scale of this scope. I would like my max to be 350,000 (dollars) and my "min" or I should say "1" value to be 5,000. How would I implement this?

If i understand correctly you want the seekbar to move by 5,000 up to 350,000.
350,000 / 5,000 = 70
final TextView textView = findViewById(R.id.some_text);
seekBar.setMax(69);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if (fromUser) {
seekBar.setProgress(progress);
textView.setText(String.valueOf((progress+1)*5000));
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
Please tell me if I misunderstood :)

int min=5000;
int max=350000;
int value = (seekBar.getProgress()*(max-min))+min;

Increment Seekbar progress by 0.5 android

My seekbar range is 2-15 , i want to increase the progress by 0.5 for each click on the seekbar. I have browsed and could not find a way.
in oncreate()
sbTaux.setProgress(0) //default value.
sbTaux.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
progress = progress / 1;
progress = progress * 1;
if (progress<=2){
progress=2;
sbTaux.setProgress(0);
}
else {}
txTaux.setText(Util.decimalFormat(progress));
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

Make range 4-30 and then just divide the result by 2 should do the trick

int myProgress;
SeekBar seekBar = (SeekBar)layout.findViewById(R.id.seekbar);
TextView seekBarValue = (TextView)layout.findViewById(R,id.TextView1);
seekBar.setProgress(2);
seekBar.incrementProgressBy(1/2);
seekBar.setMax(15);
seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
myProgress = progress;
seekBarValue.setText(myProgress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
