Can't find an element on a webview page of an andriod hybrid app using Appium

I am not able to find the elements from android.webkit.webview package using java appium script.

How to get the userText field and password field locators.so that i can pass the value to UI using the Appium script

Go to https://developer.chrome.com/devtools/docs/remote-debugging

get below property enabled by developer
http://developer.android.com/reference/android/webkit/WebView.html#setWebContentsDebuggingEnabled(boolean)

Once it is done. use below code

                By webView = By.className("android.webkit.WebView");
                WebDriverWait wait = new WebDriverWait(driver,300);
                wait.until(ExpectedConditions.visibilityOfElementLocated(webView));
		Set<String> availableContexts = driver.getContextHandles();
		System.out.println("Total No of Context Found = "+ availableContexts.size());
		for(String context : availableContexts) {
			if(context.contains("WEBVIEW")){ 
				System.out.println("Context : " + context);
				driver.context(context);
				break;
			}				 
		}
