How to get webview (load url) on a specific page of my android app source code?

I want to add webview (load url) in a only page of my app soure code
example : fragment_comingsoon.xml
want it to load an url
anybody can tell me what to do or send me an example code to do that
I will apreciate it so much and thanks in advance guys

**MainActivity**
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
public class MainActivity extends Activity {
private WebView webView = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.webView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
WebViewClientImpl webViewClient = new WebViewClientImpl(this);
webView.setWebViewClient(webViewClient);
webView.loadUrl("https://www.journaldev.com");
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && this.webView.canGoBack()) {
this.webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
**Setting the WebViewClient:**
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
return false;
}
}
**WebViewClientImpl:**
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewClientImpl extends WebViewClient {
private Activity activity = null;
public WebViewClientImpl(Activity activity) {
this.activity = activity;
}
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
if(url.indexOf("journaldev.com") > -1 ) return false;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
activity.startActivity(intent);
return true;
}
}
**Adding Permissions:**
To fetch and load the urls in the WebView we need to add permissions to access the internet from within the app else it won’t be able to load the webpages. The following
line of code needs to be added in the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
package="com.journaldev.webview" >
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

How to update webview?

I need to update my webview because doesnt show anything until i rotate the screen.
My Webview
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment3, container, false);
webview = (WebView)v.findViewById(R.id.WebView);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);
webview.setLayerType(View.LAYER_TYPE_HARDWARE, null);
webview.setWebChromeClient(new WebChromeClient());
String url = "http://www.acr-sl.com/catalogo/1/1/1";
webview.loadUrl(url);
return v;
}
UPDATE: Finally solved this problem creating the webview from 0 ina new fragment, the only thing it changed were the layouts so the problem was derived from there i suppose.

my Layout file fragment_meru_detail is as
<LinearLayout
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:orientation="vertical"
>
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/pageload"
android:layout_gravity="center"
android:text="Loding........"
/>
<WebView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="#+id/meruweb"
></WebView>
</LinearLayout>
My Java Class is as:
package com.rayz.digitalpostbox.fragments;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
import android.widget.TextView;
import android.widget.Toast;
import com.rayz.digitalpostbox.R;
import com.rayz.digitalpostbox.activities.HomeActivity;
public class MeruDetail extends Fragment {
TextView pageload ;
WebView webview ;
private ProgressBar progres;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_meru_detail, container, false);
((HomeActivity)getActivity()).setTitle("MERU Cabs");
webview = (WebView) rootView.findViewById(R.id.meruweb);
pageload = (TextView) rootView.findViewById(R.id.pageload);
progres = (ProgressBar)rootView.findViewById(R.id.progressBar);
progres.setMax(100);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
webview.getSettings().setSupportZoom(true);
webview.loadUrl("http://merucabs.com/mobile/");
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
MeruDetail.this.setValue(progress);
super.onProgressChanged(view, progress);
if(progress==100){
progres.setVisibility(View.GONE);
}else {
progres.setVisibility(View.VISIBLE);
}
if(progress>40){
pageload.setVisibility(View.GONE);
}
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getActivity(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
MeruDetail.this.progres.setProgress(0);
return rootView ;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
public void setValue(int progress) {
this.progres.setProgress(progress);
}
#Override
public void onPause() {
super.onPause();
((HomeActivity)getActivity()).setTitle("Dashboard");
}
}
And I think you should also check in your mainfest file for internet permission
<uses-permission android:name="android.permission.INTERNET" />

You can use this for your WebView
webview.reload()

you can webView.reload() but be aware this reposts a page if the request was POST, so only works correctly with GET.
If your URL is static or same then you should use loadURL again it's better.
YourActivity.this.webView.loadUrl("http://www.website.com");

below is working code for your requirement have look and implement it as>
Layout file is as:
<?xml version="1.0" encoding="utf-8"?>

How do i get my web view fit to screen?

I have implemented a web view to play a embedded flv video in my application. And it WORKS! but the problem is video frame is too small.. (video only takes about 1/8 of the screen) How can i make my video fit to screen?
Here's my code
MainActivity.java
package com.example.webvideo;
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
public class MainActivity extends Activity {
private WebView mWebView;
private LinearLayout mContentView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContentView = (LinearLayout) findViewById(R.id.linearlayout);
mWebView = (WebView) findViewById(R.id.webView);
mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
WebSettings webSettings = mWebView.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
mWebView.loadUrl("http://www.fortunagate.com/adaderana_apps/video_player.php?video=http://derana.lk/content/video/SriGauthamaSambuddha24-15thJune2014.flv");
mWebView.setWebViewClient(new HelloWebViewClient());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.setWebChromeClient(new WebChromeClient() {
private View mCustomView;
#Override
public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
{
// if a view already exists then immediately terminate the new one
if (mCustomView != null)
{
callback.onCustomViewHidden();
return;
}
// Add the custom view to its container.
mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
mCustomView = view;
mCustomViewCallback = callback;
// hide main browser view
mContentView.setVisibility(View.GONE);
// Finally show the custom view container.
mCustomViewContainer.setVisibility(View.VISIBLE);
mCustomViewContainer.bringToFront();
}
});
webview.loadUrl(url);
return true;
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())
{
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
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" >
<FrameLayout
android:id="#+id/fullscreen_custom_content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF000000"/>
<LinearLayout
android:id="#+id/linearlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</RelativeLayout>

I think you should have your WebView like this:
<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" >
<FrameLayout
android:id="#+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"/>
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</RelativeLayout>
Then, when you want it to appear just change the visibility to visible and it will cover the entire screen.

Android webview geo: and tel: links

I made android web app which uses WebView. The problem is when I press the geo: or tel: links it stops working. I tried a lot of tips from here, but non of them actualy work.
XML layout:

android:screenOrientation="portrait">

android:layout_width="fill_parent"

</FrameLayout>

// Stop local links and redirects from opening in browser instead of WebView
mWebView.setWebViewClient(new MyAppWebViewClient());

mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.setInitialScale(1);
}
#Override
// Detect when the back button is pressed

I'm pretty new to this, and I took this instructions to make the app https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
So, can anybody try to fill what is missing to make it to not crash when geo: or tel: link is pressed and handle the geo: and tel: links like in chrome?
I found the answer!!!
I replaced this code in MyAppWebViewClient.java
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
with this one
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost() != null && Uri.parse(url).getHost().equals("domain.com"))
{
return false;
}
else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
}

webView android

I am trying to make a simple WebView in my activity and I keep getting a "webpage not available" page in my android browser on the virtual device as well as an actual device.
I've looked though some samples online as well as the example in my book but I believe something is still missing. Any help would be appreciated. Code is below. wv is referencing a webview object in the main.xml file.
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView wv = (WebView) findViewById(R.id.webView1);
WebSettings webSettings = wv.getSettings();
wv.getSettings().setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
wv.loadUrl("http://www.amazon.com");
}
}

For an android webView you need to keep 4 things in mind to make it work perfect.
Give the necessary permission to access internet in your android Manifest.xml
Import necessary libs like webclient and webchromeclient in your YourActivity.java
Enable javascript if you are going to show a webpage which needs java support.
Copy and paste all the image files you use in your webView to all the "drawable" folders in "res" folder of your project.
I've given you the complete code from Manifest to Activity.java. It works perfect. All the best..!
AndroidManifest.xml:

please add the INTERNET permissions in manifest.xml...
you can also view my app using webview....
