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);
}
}
);

How to set seekbar min and max value
(15 answers)
Closed 3 years ago.
i have this code to make some editor text and custom font size with seekbar, how to make a minimum value for int progres seekbar?
seekerFont.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
fontsize.setText(""+ progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
You can set minimum or maximum progress
eekerFont.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){
public void onStopTrackingTouch(SeekBar seekBar) {
//TODO My code goes here
int CurrentLevel = eekerFont.getProgress();
if (CurrentLevel < 30) CurrentLevel = 30;
eekerFont.setProgress(CurrentLevel);
}
public void onStartTrackingTouch(SeekBar seekBar){
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser){
}});
In XML Also you can set
android:progress="10"
eekerFont.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
int progressChanged = minimumValue;
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
progressChanged = minimumValue+ progress;
}
});

Another better way is to do with little logic, For example you want to set values between 50 to 100. Then Do like this
seekBar.setMax(50);
int selectedProgress = seekBar.getProgress() + 50; // or in change listener
I want to create seek bar, I want increment like this seek bar
minvalue = 5, maxvalue = 10
seek bar value increments : 0 1 2 3 4 5 6
I want seek bar values like this : 5.10, 5.20, 5.30... 9.90, 10
How to achieve this.?
aSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
float value = ((float)progress / 20.0);
String yourprogress = String.valueOf(value+5.0f);
// yourprogress is your desiger output
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {}
});
aSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
float value = ((float)progress / 20.0);
String progress = String.valueOf(value+5.0f);
// value now holds the decimal value between 0.0 and 10.0 of the progress
// Example:
// If the progress changed to 45, value would now hold 4.5
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {}
});
this is impossible with float.
You have to make a workaround by multiply your increment.

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;
I'd like to set a max progress value in a Seekbar that is not the same as the max value.
For example max would be 100 and max progress 50, so the progress slider could only be dragged to the middle. Is there a way to do that?
You can try the following
int seekBarMaxValue = 100;
int seekBarDraggableMaxValue = 50;
seekBar.setMax(seekBarMaxValue );
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangetListener() {
public void onProgressChanged (SeekBar seekBar, int progress, boolean fromUser) {
seekBar.setProgress(progress > seekBarDraggableMaxValue ? seekBarDraggableMaxValue : progress);
}
});
Hope it helps.
It seems like you want three numbers only (ex. 0; 50; 100); just pretend each number is represents another number or multiply the progress by the common divisor:
Example
0 = 0 or (0 * 50)
1 = 50 or (1 * 50)
2 = 100 or (2 * 50)
int int_actual_number = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
seek_sample.setMax(2);
seek_sample.setProgress(0);
seek_sample.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
int_actual_number = progress * 50;
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
You can use different common divisors and amount of numbers to test this method for your needs.
I'd like to set max and minimum limits of SeekBar to 50 and 20 respectively.
SeekBar has a direct option top provide max value, but how to set its minimum value to 20 rather than 0?
In SeekBar you can set only max value.
<SeekBar android:id="#+id/SeekBar01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:max="50"/>
And,
You cannot directly set the minimum value to the seekbar.
SeekBar mSeekbar = (SeekBar) findViewById(R.id.SeekBar01);
mSeekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener()
{
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
length_edit.setText(Integer.toString(progress + 20));
}
public void onStartTrackingTouch(SeekBar seekBar) {}
public void onStopTrackingTouch(SeekBar seekBar) {}
});
As you see min progress you can sum with min which I would like - in your case 20.
Set the max value to 30 and add 20 to the values you read from the SeekBar.
The simplest way to do this is to just limit it in the SeekBar.OnSeekBarChangeListener() for your SeekBar.
First, you need to create field with min or default value. Then set this value when creating SeekBar:
private int fillDefault;
In onCreateView() of a Fragment or onCreate of an Activity:
fillDefault = 20;
fillSeekBar.setProgress(fillDefault);
Second, implement the listener for it:
fillSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
// Notification that the progress level has changed.
if (progress < fillDefault){
seekBar.setProgress(fillDefault); // magic solution, ha
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// Notification that the user has started a touch gesture.
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// Notification that the user has finished a touch gesture.
}
});
It works. Simple and awesome:D
For example;
public static int LENGTH_MIN_VALUE = 20;
public static int LENGTH_MAX_VALUE = 50;
SeekBar seekBar = (SeekBar) findViewById(R.id.passwordSeekBar);
seekBar.setMax(LENGTH_MAX_VALUE);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(progress <= Constract.PASSWORD_LENGTH_MIN_VALUE){
progress = Constract.PASSWORD_LENGTH_MIN_VALUE + progress;
}
String numberAsString = String.valueOf(progress);
seekNumberView.setText(numberAsString);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {}
});
I have answered this question here : How to set seekbar min and max value.
With simple math you can set the min value, the max value and even the step of your seekbar.
Hope this helps !
You can try this:
seekBar.setMax(max_value-min_value);
