Don't overlap Pins in com.appyvet.rangebar.RangeBar

I am using this library to create Double RangeBar in android. Now in this rangebar i want that if left pin overlaps the right pin it must return to its previous position instead of overlapping and same for right pin. This is same as used in flipkart to filter price ranges.(Flipkart uses Range bar like this). I want to implement same property like that. How can i implement this property. Please help me..
Thanks in advance.
This is my Activity and xml
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.range_bar);
min = (TextView)findViewById(R.id.min);
sign_rupees = (TextView)findViewById(R.id.sign_rupees);
sign_rupees2 = (TextView)findViewById(R.id.sign_rupees2);
selected_min = (TextView)findViewById(R.id.selected_min);
selected_max = (TextView)findViewById(R.id.selected_max);
rangeBar = (RangeBar)findViewById(R.id.rangebar3);
rangeBar.setOnRangeBarChangeListener(this);
}
#Override
public void onRangeChangeListener(RangeBar rangeBar, int leftPinIndex, int rightPinIndex, String leftPinValue, String rightPinValue) {
int diff = rightPinIndex-leftPinIndex;
if (diff == 0){
rangeBar.setRangePinsByIndices(leftPinIndex-1,rightPinIndex+1);
rangeBar.setEnabled(true);
}else{
rangeBar.setEnabled(true);
if (leftPinIndex == 0){
min.setText("Min");
min.setVisibility(View.VISIBLE);
sign_rupees.setVisibility(View.INVISIBLE);
selected_min.setVisibility(View.INVISIBLE);
}else{
min.setVisibility(View.GONE);
sign_rupees.setVisibility(View.VISIBLE);
selected_min.setVisibility(View.VISIBLE);
selected_min.setText(String.valueOf(leftPinIndex*500));
}
if (rightPinIndex == 6){
selected_max.setText("2500+");
}else{
selected_max.setText(String.valueOf(rightPinIndex*500));
}
}
}

I haven't used this library , but looking at their code what you can try is :
#Override
public void onRangeChangeListener(RangeBar rangeBar, int leftPinIndex, int rightPinIndex, String leftPinValue, String rightPinValue) {
int diff = rightPinIndex-leftPinIndex;
if (diff == 0){
rangeBar.setRangePinsByIndices(leftPinIndex-1,rightPinIndex+1);
rangeBar.setEnabled(true);
}else{
rangeBar.setEnabled(true);
if (leftPinIndex == 0){
min.setText("Min");
min.setVisibility(View.VISIBLE);
sign_rupees.setVisibility(View.INVISIBLE);
selected_min.setVisibility(View.INVISIBLE);
}else{
min.setVisibility(View.GONE);
sign_rupees.setVisibility(View.VISIBLE);
selected_min.setVisibility(View.VISIBLE);
selected_min.setText(String.valueOf(leftPinIndex*500));
}
if (rightPinIndex == 6){
selected_max.setText("2500+");
}else{
selected_max.setText(String.valueOf(rightPinIndex*500));
}
}
if(rightPinIndex <= leftPinIndex) {
rangebar.setRangePinsByIndices(leftIntIndex-5, rightIntIndex+5); // This +-5 value can be anything
}
}

Hiding keyboard in fragments

I am having a fragment and in that fragment there is an add button which triggers a dialog when clicked . In that dialog I am having two edittext and two buttons. On click of save button dialog is dismissed. Now problem is that when I click on save button edit text keyboard closes and another keyboard pop up.(Edit text keyboard type is number while that popup after is alphabetical).I want to close this keyboard therefore I tried configChanges and this method
public static void hideKeyboard(Context ctx) {
InputMethodManager inputManager = (InputMethodManager) ctx
.getSystemService(Context.INPUT_METHOD_SERVICE);
// check if no view has focus:
View v = ((Activity) ctx).getCurrentFocus();
if (v == null)
return;
inputManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
But none of this method works and I am also not having any edit text in fragment from which dialog appears.

What's the issue here??
**EDIT:**After checking for each edit text individually I found that the keyboard from first editext didn't closes itself.So I added focus change listener and when it loses focus I called hide Keyboard.
I debugged line by line and everything works perfectly, debugger also enters hide keyboard method but that code is not able to hide keyboard. Is there any other method for hiding keyboard in fragments??
Is this problem with context that is passed in hide keyboard method ??Can we get context of an alert dialog in android because when I debug it showing context of Main Activity as I am passing getActivity() as parameter .Is this the issue??

public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
create this methos infragment and call this method where u want to hide keyboard in your fragment.

Hiding Keyboard using method doesn't work for me. I added the code directly in submit button and that worked for me. Here is what I added
InputMethodManager im = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
im.hideSoftInputFromWindow(et_name.getWindowToken(), 0);
InputMethodManager im1 = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
im1.hideSoftInputFromWindow(et_dns.getWindowToken(), 0);
Here et_dns and et_name are my edit text

I got a bit lost in your code, but if I understood right you may need to have the main view as a parameter in rowView = inflater.inflate(R.layout.dummaa, null); instead of passing null.

java.lang.NumberFormatException is there a better way around this issure?

Here is my Java file for my app that I am working on. The in logcat it is saying there is an error in the initvar() method in this line "length1et = (EditText) findViewById(R.id.etlength1);" I know this is because there is not a variable in the edittext box and I have had this problem before and just put 0's there to start out. Is there a simple command to have nothing there and it will just understand to automatically put in a 0 for the value or is the only way to write some code to treat it as a zero? Below the java code is the xml if that is necessary. In a previous app I have just had it read the edittext box and if nothing is there, set the value to 0 before it does anything else. For the record I know I don't have a button to call the calculate() method I just haven't put that in yet.

Try this:
lengthft = Double.parseDouble(length1et.getText().toString()+0);
But be aware, if the user type in a invalid number and click on the button you haven't implemented yet, your app will crash. So you should probably add a check to all the EditText's before you call calculate().
Or even better, add a function to do it for you:
lengthft = getDouble(length1et);
public double getDouble(EditText et) {
if (!et.getText().equals(null)) {
return Double.parseDouble(et.getText().toString()); //convert your string into integer
} else {
return 0; // or what you want to return if string is Null
}
}

half or quarter black screen in android

I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity
