So guys. I have a problem, I am creating an application and while the webview is charged, appears a ProgressBar loading before the content, see my code. The problem is that when you start the app, there is a white activity in place of the webview w the ProgressBar not appear. Follows the code.
<FrameLayout
android:id="#+id/framelayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:visibility="invisible"/>
<ProgressBar
android:id="#+id/progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="invisible"/>
</FrameLayout>
</RelativeLayout>
NOW MY CLASS:
// CODE WebView
final WebView myWebView = (WebView) findViewById(R.id.webView);
myWebView.loadUrl("http://www.idestudos.com.br");
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(true);
webSettings.setBuiltInZoomControls(true);
myWebView.setWebViewClient(new MyBrowser());
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
myWebView.setWebViewClient(new WebViewClient(){
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
ProgressBar pb = (ProgressBar) findViewById(R.id.progress);
pb.setVisibility(View.VISIBLE);
}
public void onPageFinished(WebView view, String url){
ProgressBar pb = (ProgressBar) findViewById(R.id.progress);
pb.setVisibility(View.INVISIBLE);
myWebView.setVisibility(View.VISIBLE);
}
});
}`
Your root FrameLayout has height set to 0dp, i.e., android:layout_height="0dp", but has weight set to 1, android:layout_weight="1", are you sure if its inside a LinearLayout? If not change the height to android:layout_height="match_parent" or something.
Also, you're setting the client twice.
myWebView.setWebViewClient(new WebViewClient() {...}); two times there in the code.
Do this instead.
myWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
ProgressBar pb = (ProgressBar) findViewById(R.id.progress);
pb.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url){
ProgressBar pb = (ProgressBar) findViewById(R.id.progress);
pb.setVisibility(View.INVISIBLE);
myWebView.setVisibility(View.VISIBLE);
}
});
Put the progressbar inside FrameLayout and FrameLayout below WebView so that the progressBar will stay on your screen even when you scroll through the WebView...
<RelativeLayout
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"
android:layout_centerVertical="true"
/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="150dp">
<ProgressBar
<!-- your progress bar here-->
/>
</FrameLayout>
</RelativeLayout>

I'm new at android developing, so asking you for help.
I have the code like that:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout android:layout_width="fill_parent"
android:id="#+id/home_layout"
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_above="#+id/adView">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="10dp"
android:id="#+id/progressBar" />
</LinearLayout>
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>
In my logic, AdBlock should display at the bottom of view. But in my case it's just not appearing at all. If I past Ad's markup inside LinearLayout it gives me crash of VM.
What I'm doing wrong? Thank you in advance
UPD: Java activity
public class PddViewActivity extends ActionBarActivity{
private WebView webView;
private ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pdd_view);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
String file = getIntent().getStringExtra("file");
webView = (WebView) findViewById(R.id.webview);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.i("PROGRESS IS :", newProgress+"");
progressBar.setProgress(newProgress);
}
});
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getApplicationContext(), "Error: " + description + " " + failingUrl, Toast.LENGTH_LONG).show();
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressBar.getVisibility() == WebView.VISIBLE) {
progressBar.setVisibility(WebView.GONE);
}
}
});
webView.loadUrl(String.format("file:///android_asset/html/%s", file));
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
}
return super.onOptionsItemSelected(item);
}
}
Your problem is that home_layout has a layoutHeight of match_parent, which means it will consume all the height of its parent leaving none for you adView.
Instead use wrap_content and specify android:layoutWeight="1" to tell it to consume all unused space. Eg
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/home_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="10dp"
android:id="#+id/progressBar" />
</LinearLayout>
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>
Note also:
layout_above has no meaning except within a relative_layout.
fill_parent has been deprecated, use match_parent instead.
You had the same problem with your WebView.
Try with that in your PddViewActivity.java :
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
private WebView webView;
private ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pdd_view);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//instaciate AdView
AdView mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
String file = getIntent().getStringExtra("file");
webView = (WebView) findViewById(R.id.webview);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
Log.i("PROGRESS IS :", newProgress+"");
progressBar.setProgress(newProgress);
}
});
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getApplicationContext(), "Error: " + description + " " + failingUrl, Toast.LENGTH_LONG).show();
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressBar.getVisibility() == WebView.VISIBLE) {
progressBar.setVisibility(WebView.GONE);
}
}
});
webView.loadUrl(String.format("file:///android_asset/html/%s", file));
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
}
return super.onOptionsItemSelected(item);
}
}
I am trying to get a progress bar which shows until the web page is loaded. and if user has no internet connection than a text or toast is showed... but i am unable to get it worked.. searched the whole website. i think its easy to add progress bar to class that expends Activity...
here is my class and layout
package com.nirav.rpta.fragments;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebSettings;
import android.webkit.WebView;
import com.nirav.rpta.R;
public class OneFragment extends Fragment{
public OneFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
WebView heroespage = (WebView) rootView.findViewById(R.id.webview);
WebSettings webSettings = heroespage.getSettings();
webSettings.setJavaScriptEnabled(true);
heroespage.loadUrl("http://google.co.in/");
return rootView;
}}
and my layout
<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"
tools:context="com.nirav.rpta.fragments.OneFragment">
<WebView
android:id="#+id/webview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
/></RelativeLayout>
Add a ProgressBar to your layout file:
<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"
tools:context="com.nirav.rpta.fragments.OneFragment">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ProgressBar
android:id="#+id/progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:indeterminate="true"/>
</RelativeLayout>
Now in the code:
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
WebView heroespage = (WebView) rootView.findViewById(R.id.webview);
ProgressBar loading = (ProgressBar) rootView.findViewById(R.id.progress);
heroespage.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
loading.setVisibility(View.GONE);
heroespage.setVisibility(View.VISIBLE);
}
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
// Show error toast
}
#Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
// Show error toast
}
});
heroespage.loadUrl("http://google.co.in/");
Please check below code for the thing you want.
Your layout
<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"
tools:context="com.nirav.rpta.fragments.OneFragment">
<WebView
android:id="#+id/webview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"/>
<ProgressBar
android:id="#+id/progressBar2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
Your Java file should be like below:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
WebView heroespage = (WebView) rootView.findViewById(R.id.webview);
// Resources
progressBar = (ProgressBar) rootView.findViewById(R.id.progressBar2);
WebSettings settings = heroespage.getSettings();
settings.setJavaScriptEnabled(true);
heroespage.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// Log.i(TAG, "Processing webview url click...");
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
// Log.i(TAG, "Finished loading URL: " +url);
if (progressBar.getVisibility() == View.VISIBLE) {
progressBar.setVisibility(View.GONE);
}
}
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// Log.e(TAG, "Error: " + description);
Toast.makeText(WebViewScreen.this, "You are offline.",
Toast.LENGTH_SHORT).show();
progressBar.setVisibility(View.VISIBLE);
}
});
heroespage.loadUrl(URL);
return rootView;
}}
You must update your layout
<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"
tools:context="com.nirav.rpta.fragments.OneFragment">
<WebView
android:id="#+id/webview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
/>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:id="#+id/progbar"/>
</RelativeLayout>
And then find id of progressbar ProgressBar prog = view.findViewById(R.id.progbar);
to check internet connection use this method
public boolean isConnectingToInternet( Context _context){
ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null)
{
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null)
for (int i = 0; i < info.length; i++)
if (info[i].getState() == NetworkInfo.State.CONNECTED)
{
return true;
}
}
return false;
}
add this code in your oncreateview
heroespage.setWebViewClient(new WebViewCLient(){
public void onPageLoadFinished(){
progbar.setvisibility(View.Gone);
});
if(isconnectingInternet(getActivity()){
heroespage.loadUrl("http://google.co.in/");
}else{
// show your toast here
}
to hide / show progress bar you can use setWebViewClient which provide onPage strated and onPageFinished method
webView.setWebViewClient(new WebViewClient(){
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// Show Progress bar
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
// hide Progress bar
}
});
To check no internet connection , you can use below code
public static boolean isNetConnected() {
try {
ConnectivityManager cm = (ConnectivityManager) getSystemService(
Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return activeNetwork != null && activeNetwork.isConnectedOrConnecting();
} catch (Exception e) {
}
return false;
}
Use above method before loading url
if(isNetConnected()) {
heroespage.loadUrl("http://google.co.in/");
} else {
Toast.makeText(getActivity() ,"No internet connection",Toast.LENGTH_SHORT).show();
}
I am trying to add a progressbar to a webview class.However, even after following all steps correctly, it crashes with a null pointer exception, any idea why?
Here's my mainactivity:
public class MainActivity extends Activity {
WebView webview;
ProgressBar progress;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// getWindow().requestFeature(Window.FEATURE_PROGRESS);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
webview = (WebView)findViewById(R.id.webview);
webview.setInitialScale(1);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
progress = (ProgressBar) webview.findViewById(R.id.ProgressBar);
progress.setVisibility(View.VISIBLE);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
// webview.setWebViewClient(new MyCustomWebViewClient());
webview.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
webview.setScrollbarFadingEnabled(false);
webview.getSettings().setRenderPriority(RenderPriority.HIGH);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
// webview.getSettings().setBlockNetworkLoads(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.loadUrl("http://www.yahoo.com");
webview.getSettings().setSupportZoom(false);
/* webview.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
// update the progressBar
MainActivity.this.setProgress(progress * 100);
}
});*/
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch(keyCode)
{
case KeyEvent.KEYCODE_BACK:
if(webview.canGoBack() == true){
webview.goBack();
}else{
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
private class MyCustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
}
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
}
}
}
and here's the corresponding xml:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".MainActivity" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ProgressBar
android:id="#+id/ProgressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:maxHeight="30dp"
android:minHeight="30dp" />
</RelativeLayout>
Change
progress = (ProgressBar) webview.findViewById(R.id.ProgressBar);
to
progress = (ProgressBar)findViewById(R.id.ProgressBar);
Progressbar belongs to main.xml. findViewById looks for a view in the current inflated layout. You have set the content of layout main.xml to your activity.
I see that you copied an example, but you did it wrong. Replace the commented code with this:
webView.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int prog)
{
progress.setProgress(prog * 100);
}
});
Also, as said in the other post, that webview in webview.findViewById needs to be removed.
I have the following problem with my Android app. I'm using a webview which has a progressbar. It works ok, but the problem is that when the progressbar is set to INVISIBLE again (on progress == 100), the webview hasn't changed pages yet (it does so shortly after reshowing).
In sum, it's this:
1. Webview in view
2. Webview to gone, progressbar to visible
3. Progressbar to gone, webview to visible
4. Webview actually changes the page
My goal is to have 4 happen before 3 (and thus not showing the webview before it has actually changed the page.
How can I do this?
My codes is as follows:
public class MyActivity extends Activity { WebView mWebView;
ProgressBar pd = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
pd = (ProgressBar) findViewById(R.id.web_view_progress_bar);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
mWebView.loadUrl("http://www.myurl.com");
mWebView.setWebViewClient(new WebViewClient());
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
if(progress < 100 && pd.getVisibility() == ProgressBar.GONE){
mWebView.setVisibility(WebView.GONE);
pd.setVisibility(ProgressBar.VISIBLE);
}
pd.setProgress(progress);
if(progress == 100 && mWebView.getVisibility() == WebView.GONE) {
pd.setVisibility(ProgressBar.GONE);
mWebView.setVisibility(WebView.VISIBLE);
}
}
});
}
#Override
public void onBackPressed(){
if(mWebView.canGoBack())
mWebView.goBack();
else
super.onBackPressed();
}
}
class ClassWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
}
Layout:
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ProgressBar

You'll want to find the stacktrace from the crash, you can get this with logcat, either open the logcat view in eclipse (or open the DDMS perspective), or run adb logcat from the shell to see the log.
In this case though, i'm pretty sure you'll see any error saying you need to set the window feature before creating any content, move your setContentView call to after the getWindow().requestFeature call.
