In web view when I scroll the page little bit down then it scroll up automatically on some pages not all pages but on some pages.Why this happen and what is it solution
Here is xml code
<android.support.design.widget.CoordinatorLayout android:id="#+id/nonVideoLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<WebView
android:id="#+id/webView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.design.widget.CoordinatorLayout>
Here is my code you can check this
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
bindLayout();
mySwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
webView.reload();
}
});
CookieManager.getInstance().setCookie(url, cookie);
webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
ProgressDialogHelper.showProgress(WebViewActivity.this);
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, final String url) {
mySwipeRefreshLayout.setRefreshing(false);
}
});
webView.loadUrl(url);
}
Here is my java code I set the cookie also to web view and I set also layer type. I search that everyone says to set layer type then this problem solved but it does not solved.
try this
final WebSettings settings = mWebView.getSettings();
settings.setDomStorageEnabled(true);
settings.setJavaScriptEnabled(true);
mWebView.setVerticalScrollBarEnabled(false);
Just remove
webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
all others are OK
try this in AndroidManifest.xml
set android:hardwareAccelerated="true" in the application and activity tag.

This is probably a stupid question at this stage but I've been looking through the threads online and none of the solutions have worked for me so far.
I have an Activity that has a Webview nested inside a SwipeRefreshLayout to enable the Pull-To-Refresh functionality to refresh the page. The problem arises where when I try to scroll to the top the web page, the OnRefresh callback is being called. Below is some snippets of the relevant code I have tried related to fixing the problem. I tried to implementing the ViewTreeObserver.OnScrollChangedListener interface to enable the refresh function when the scroll is at the top. I am wondering if I am missing something.
Browser.java
public class Browser extends AppCompatActivity implements Common, ViewTreeObserver.OnScrollChangedListener {
private final String TAG = getClass().getSimpleName();
private ProgressBar loadingPageBar;
private Toolbar toolbar;
private WebView browser;
private WebSettings webSettings;
private SwipeRefreshLayout refreshLayout;
private String urlLink;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_browser);
Log.i(TAG, "onCreate: Called");
declareVariables();
getIntentData();
setSupportActionBar(toolbar);
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setNavigationOnClickListener(view -> onBackPressed());
toolbar.setBackgroundColor(ContextCompat.getColor(this, R.color.white));
toolbar.setTitleTextColor(ContextCompat.getColor(this, R.color.colorPrimary));
toolbar.setSelected(true);
webSettings = browser.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setAllowFileAccess(true);
webSettings.setDomStorageEnabled(true);
webSettings.setSaveFormData(true);
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
browser.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
refreshLayout.setRefreshing(false);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return super.shouldOverrideUrlLoading(view, request);
}
});
browser.setWebChromeClient(new ChromeClient());
enableHtml5Features();
browser.clearCache(true);
browser.loadUrl(urlLink);
refreshLayout.setRefreshing(true);
refreshLayout.getViewTreeObserver().addOnScrollChangedListener(this);
refreshLayout.setOnRefreshListener(() -> browser.reload());
}
#Override
public void onScrollChanged() {
System.out.println(browser.getScrollY());
if (browser.getScrollY() == 0)
refreshLayout.setEnabled(true);
else
refreshLayout.setEnabled(false);
}
}

Add SwipeRefreshLayoutListener i.e. setOnRefreshListener like below:
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
refreshLayout.setRefreshing(true);
loadWebView();
}
});
Whole Class with SwipeRefreshLayout Layout :
public class WebViewActivity extends AppCompatActivity {
private final String TAG = getClass().getSimpleName();
private WebSettings webSettings;
private View view3;
private ProgressBar loadingBar;
private SwipeRefreshLayout refreshLayout;
private WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
view3 = findViewById(R.id.view3);
loadingBar = findViewById(R.id.loadingBar);
refreshLayout = findViewById(R.id.swipeContainer);
webview = findViewById(R.id.webview);
webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setAllowFileAccess(true);
webSettings.setDomStorageEnabled(true);
webSettings.setSaveFormData(true);
webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
loadWebView();
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
refreshLayout.setRefreshing(true);
loadWebView();
}
});
}
private void loadWebView(){
String urlLink="https://stackoverflow.com/questions/57478675/android-webview-refreshing-when-scrolling-down";
webview.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
refreshLayout.setRefreshing(false);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
return super.shouldOverrideUrlLoading(view, request);
}
});
webview.setWebChromeClient(new WebChromeClient());
webview.clearCache(true);
webview.loadUrl(urlLink);
}
}
I hope its work for you.
When there is no connection available it displays the deafult browser error page, What is want is simply not to display any browser error page instead a toast message and a blank screen.
My code:
public class EarnFragment extends Fragment {
WebView mWebView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v=inflater.inflate(R.layout.fragment_earn, container, false);
mWebView = (WebView) v.findViewById(R.id.webview);
mWebView.loadUrl("https://demo.hazzardweb.com/easylogin-pro/");
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
return v;
}
}
if you want to display black screen instead of webview, first you need to change your layout file.
then you check internet connection before load the url.
check if internet connection not available taht time hide your webview and display your Toast message and relative layout.
Othervise hide Relativelayout noConnection.
Step 1 : create layout like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/webViewData"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<RelativeLayout
android:id="#+id/noConnection"
android:layout_width="match_parent"
android:background="#000000"
android:layout_height="match_parent"/>
</RelativeLayout>
</LinearLayout>
Step 2 : Check your internet connection using this function.
public static boolean checkInternetConnection(Context context) {
if (context != null) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (cm != null) {
return cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isAvailable() && cm.getActiveNetworkInfo().isConnected() && cm.getActiveNetworkInfo().isConnectedOrConnecting();
} else {
return false;
}
} else {
return false;
}
}
At the end do this in your code, before load you url,
public class EarnFragment extends Fragment {
WebView mWebView;
RelativeLayout noConnection;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v=inflater.inflate(R.layout.fragment_earn, container, false);
mWebView = (WebView) v.findViewById(R.id.webview);
noConnection = (RelativeLayout)v.findViewById(R.id.noConnection);
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
if(checkInternetConnection(getActivity())){
noConnection.setVisibility(View.GONE);
mWebView.setVisibility(View.VISIBLE);
mWebView.loadUrl("https://demo.hazzardweb.com/easylogin-pro/");
}else{
noConnection.setVisibility(View.VISIBLE);
mWebView.setVisibility(View.GONE);
}
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
return v;
}
Step 1: Make include_error_list_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ebebeb"
android:gravity="center"
android:orientation="vertical">
<!--android:background="#ebebeb"-->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/labelError"
android:layout_centerHorizontal="true"
android:src="#drawable/img_icon_error_list" />
<TextView
android:id="#+id/labelError"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:padding="10dp"
android:text="#string/err_error_list"
android:textColor="#color/color_app_font_primary" />
<ProgressBar
android:id="#+id/errorProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/labelError"
android:layout_centerHorizontal="true"
android:layout_margin="20dp"
android:visibility="gone"/>
</RelativeLayout>
</LinearLayout>
Step 2: Make fragment layout fragment_abc.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="#+id/errorView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<include layout="#layout/include_error_list_view" />
</RelativeLayout>
</RelativeLayout>
Step 3: Bind Layout with JAVA.

private final String TAG = "AbcFragment";

all permissions ok. al settings ok, app version 28 (android 9 pie)
im click "Visiblity Test" link not change any screen activity,
and after scroll to bottom nofication top bar click toggle auto rotate screen button
auto refresh and show LinearLayout front of the webview control.
how to fix this problem.
not showing LinearLayout and webView not invisible with "Visiblity Test" clicked. after need a refreshing action.
Sorry my English is bad :(
im found this problem,
returned error "Only the original thread that created a view hierarchy can touch its views"
So then you need me: runOnUiThread()
extend this code...
public static void showLayoutMA() {
CurrentActivitiy.runOnUiThread(new Runnable() {
#Override
public void run() {
//mWebView.setVisibility(WebView.INVISIBLE);
ny_sms.setVisibility(LinearLayout.VISIBLE);
}
});
why not use direct runOnUiThread(new Runnable() {} function, because my function is static, im add "CurrentActivitiy" declaration of MainActivity.
static Activity CurrentActivitiy;
CurrentActivitiy = (Activity)MainActivity.this;
and after few hours happy ending, problem is resolved..
I am working on a simple Android App which uses WebView.
The code is:
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/linear1"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/editUrl"
android:layout_weight="3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/url_hint"/>
<Button
android:id="#+id/buttonGo"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="#string/url_go"/>
</LinearLayout>
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/linear1"
tools:context=".MainActivity" />
</RelativeLayout>
MainActivity.java
public class MainActivity extends ActionBarActivity {
WebView mWebView;
EditText editText;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.buttonGo);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
editText = (EditText)findViewById(R.id.editUrl);
String url = editText.getText().toString();
mWebView = (WebView) findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl(url);
}
});
}
}
However, this code doesn't seem to work. I don't know why. It was working perfectly when I did not add any EditText or Button, and the code in the MainActivity.java was:
public class MainActivity extends ActionBarActivity {
WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url = "http://google.com";
mWebView = (WebView) findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl(url);
}
});
}
}
I have no idea why this is happening because the app seemed to work fine before.
When I changed the layout, the app doesn't work.
Please help me in detail as I am new to Android.
Thanks.
PLEASE FEEL FREE TO SUGGEST ME A BETTER METHOD TO IMPLEMENT THIS ALSO
Create java object of all other view objects like web view before it and then try.
I just tried your code as is, and it worked. One thing to note though, you have to type in the full url, for example: http://www.example.com.
One improvement would be to make it so you just have to type in example.com by doing something like this:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
editText = (EditText)findViewById(R.id.editUrl);
String url = editText.getText().toString();
if (!url.contains("www")){
url = "www." + url;
}
if (!url.contains("http")){
url = "http://" + url;
}
mWebView = (WebView) findViewById(R.id.webView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl(url);
}
});
I tried to log in my app using Gmail log in Authentication using web view, when i run using emulator always shows the web page is not available.Please find the attached screen shoot.I do not understand how this comes, please any body suggest me how to get gmail log in authentication and user token.
Thanks in advance

[Here][1] is a perfect example.
[1]: http://tush.wordpress.com/2014/07/15/android-google-contact-api-3-0-example/
Use the authentication process from this example.
And also in your code clientID is blank it can't be empty for debug mode it should
be empty for only release mode of your application
