Android Seekbar float values from 2.0 to 8

Hi i am new for android and in my app i have one seeckBar
for measuring persons height my seeckBar min range is--->2 and max range is---->8
Here i want to show my seeckBar values like 2.0,2.1,2.5.....2.12,
After 2.12 i want to show seeckBar range is 3ft's in that way process is need going up to 8ft's
How can i do this can some one help me please
code:-
try {
CrystalSeekbar height_seeckBar = (CrystalSeekbar) view.findViewById(R.id.height_seeckBar);
height_seeckBar.setOnSeekbarChangeListener(new OnSeekbarChangeListener() {
#Override
public void valueChanged(Number value) {
long i = (long)value;
float finalValue = i/12;
total_height.setText("" + finalValue + " (ft)");
}
});
} catch (Throwable throwable) {
throwable.printStackTrace();
}

ScrollTo and ScrollToExact equivalent for webView in appium for android

I am automating android app using appium (java).For scrolling on native components, I use scrollTo() and scrollToExact() methods.But in case of webView inside the app ; these methods are not working.
UPDATE:
I have tried these two methods also:
public static void scrollNavigation(AppiumDriver<MobileElement> wd, String widID, String target, String direction)
{
JavascriptExecutor js = (JavascriptExecutor) wd;
HashMap<String, String> swipeObject = new HashMap<String, String>();
swipeObject.put("text", target);
swipeObject.put("direction", direction);
swipeObject.put("element", widID);
js.executeScript("mobile: scrollTo", swipeObject);
wait(200);
}
public static void swipeUpElement(AppiumDriver<MobileElement> driver, MobileElement element, int duration)
{
int topY = element.getLocation().getY();
int bottomY = topY + element.getSize().getHeight();
int centerX = element.getLocation().getX() + (element.getSize().getWidth()/2);
driver.swipe(centerX, bottomY, centerX, topY, duration);
}
But in both these I need element- but on the page I cannot find any element except the webview.I am using UiAutomator to capture the IDs.Any suggestions / link / workaround will be helpful

ELements arent displaced uniquely in web view. U need to develop mathematical logic to get screen size and scroll according to them, use the below code,
public void scroll() throws IOException {
try {
Dimension dimensions = driver.manage().window().getSize();
System.out.println("Size of Window= " +dimension);
int scrollStart = (int) (dimension.getHeight() * 0.5);
System.out.println("Size of scrollStart= " +scrollStart);
int scrollEnd = (int) (dimension.getHeight() * 0.2);
System.out.println("Size of cscrollEnd= " + scrollEnd);
driver.swipe(0,scrollStart,0,scrollEnd,1000);
Application_Log.info("Screen Swiped " );
} catch (IOException e) {
Assert.fail("Swipe failed");
}
}

Try switching to native context driver.context("NATIVE_APP"); before scroll .
If it does not work then give a try for JavascriptExecutor like below sample
MobileElement element = driver.findElement(By.xpath("element-xpath"));
JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap scrollObject = new HashMap();
scrollObject.put("direction", "down");
scrollObject.put("element", element);
js.executeScript("mobile: scroll", scrollObject);

Android: How to get scroll position when displaying document files in webview by using gview of Google

I am using gview of Google Docs to display document files but I cannot get scroll position as well as set scroll offset to force document view jump to any positions.
Here is my code:
String url = "https://dl.dropbox.com/s/8wubzwsbcafqxmt/GMAT-Vocabulary-List.pdf?dl=0";
webView.loadUrl("https://docs.google.com/viewer?url=" + url + "&embedded=true");
public boolean onTouchEvent(final MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_MOVE) {
int xPos = webView.getScrollX();
int yPos = webview.getScrollY();
Log.d("Scroll", "xPos = " + xPos + ";yPos = " + yPos);
}
return false;
}
The logcat is always like this: "xPos = 0;yPos = 0".
And nothing happens when I set webView position like this:
webView.setScrollY(1000);
I have no idea why!
I searched and tried many solutions but this problem is still not resolved. Could you please show me some ways to resolve this problem.
Thank you in advance!

ValueAnimator doesn't trigger properties methods

I had been debugged the following code for whole day, and have no idea why it doesn't work as expected.
import com.nineoldandroids.animation.ObjectAnimator;
import com.nineoldandroids.animation.PropertyValuesHolder;
import com.nineoldandroids.animation.ValueAnimator;
private void animateThumbCoorToMatchCurrentIndixes() {
float newThumbLeftCoor = this.indexToCoor(this.thumbLeftIndex);
float newThumbRightCoor = this.indexToCoor(this.thumbRightIndex);
PropertyValuesHolder thumbLeftPropertyValuesHolder = PropertyValuesHolder.ofFloat("thumbLeftCoor", this.thumbLeftCoor, newThumbLeftCoor);
PropertyValuesHolder thumbRightPropertyValuesHolder = PropertyValuesHolder.ofFloat("thumbRightCoor", this.thumbRightCoor, newThumbRightCoor);
Log.i("CHEOK", "Animate " + this.thumbLeftCoor + " -> " + newThumbLeftCoor);
Log.i("CHEOK", "Animate " + this.thumbRightCoor + " -> " + newThumbRightCoor);
ValueAnimator valueAnimator = ObjectAnimator.ofPropertyValuesHolder(this, thumbLeftPropertyValuesHolder, thumbRightPropertyValuesHolder);
valueAnimator.setDuration(getResources().getInteger(android.R.integer.config_shortAnimTime));
valueAnimator.setRepeatCount(0);
valueAnimator.setInterpolator(new DecelerateInterpolator());
Log.i("CHEOK", "Animation duration = " + valueAnimator.getDuration());
valueAnimator.start();
}
// Do not remove this code. It is used for reflection call for animation.
#SuppressWarnings("unused")
private void setThumbLeftCoor(float thumbLeftCoor) {
this.thumbLeftCoor = thumbLeftCoor;
Log.i("CHEOK", "SET thumbLeftCoor " + thumbLeftCoor);
this.postInvalidate();
}
// Do not remove this code. It is used for reflection call for animation.
#SuppressWarnings("unused")
private void setThumbRightCoor(float thumbRightCoor) {
this.thumbRightCoor = thumbRightCoor;
Log.i("CHEOK", "SET thumbRightCoor " + thumbRightCoor);
this.postInvalidate();
}
My console log is as follow :
Animate 636.0985 -> 0.0
Animate 679.27057 -> 578.0
Animation duration = 200
However, methods setThumbLeftCoor and setThumbRightCoor never get triggered.
Anyone have idea why it happens so?

All the while, by having setThumbLeftCoor and setThumbRightCoor as private method work for my case.
Just that recently, a child class is being derived from the above class.
To make the above code work as it is, changing setThumbLeftCoor and setThumbRightCoor to public method is required. (Even protected won't work)
My guess is, this is due to limitation of "reflection"

How can I limit the length of content in the webview?

Let's say that I have a WebView:
#Override
public void onPageFinished(WebView view, String url)
{
Log.d(TAG, "Finished: " + url);
super.onPageFinished(view, url);
Log.d(TAG, "webView.getContentHeight(): " + webView.getContentHeight());
Log.d(TAG, "webView.getHeight(): " + webView.getHeight());
Log.d(TAG, "view.getContentHeight(): " + view.getContentHeight());
}
where it returns:
webView.getContentHeight(): 4059
webView.getHeight(): 1746
Now, I'd like to chop off bottom 500 pixels of the web contents (e.g. 4059 px --> become 3559 px) while still maintaining it's viewable webview height 1746.
Could anyone give me an idea? I'd sincerely appreciate that!

Not sure what you're trying to accomplish - changing the "contentHeight" requires changing the content and re-loading the page.
So I assume you are trying to prevent the content from being seen, in which case you can override scrollTo and prevent the scroll from going past a specific margin of content like so:
int myMargin = 500;
Then:
#Override
public void scrollTo(int x, int y){
int maxScroll = webView.getContentHeight() - myMargin;
if (y > maxScroll) {
super.scrollTo(x, maxScroll);
} else {
super.scrollTo(x,y);
}
}
