I have 5 buttons and i need to open different webpages after buttons is clicked. How to make it?
my java code for webview activity:
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebView extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView v, String url)
{
v.loadUrl(url);
return true;
}
}
And xml:
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context="lv.shit.test.Sakums" >
<webview android:id="#+id/manswebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</webview>
</linearlayout>
What should I write on OnClick to open webpages in my webview?
You can load different pages on your webView object on the click.
as
webView.loadUrl("http://googlecom");
You can pas the url to the method loadUrl() under the webView object to preform the loading of different urls.
Call this method inside the onClick listener:
loadWebView(url);
public void loadWebView(String url){
/*
* Setting the options of my webView
*/
mWebView = (WebView)findViewById(R.id.manswebview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.getSettings().setDisplayZoomControls(false);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
mWebView.loadUrl(url);
mWebView.setWebChromeClient(new WebChromeClient() {
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
}
#Override
public void onCloseWindow(WebView window) {
super.onCloseWindow(window);
}
});
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
//when finish loading page
public void onPageFinished(WebView view, String url) {
}
});
//done loading now render the content
this.setContentView(mWebView);
}

I'm loading one URL in WebView, the URL page contains functionality of capturing image from device camera OR select image from gallery. If I open URL in Browser, everything works fine but, if I open the same URL in WebView then Camera and Gallery functionality do not works. I think I'm missing some WebView setting. Please check my below code and help me to solve my problem.
Below is my WebViewActivity--
public class WebViewActivity extends AppCompatActivity
{
WebView myWebView;
ProgressBar myProgress;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_webview);
findViews();
}
private void findViews()
{
myWebView= (WebView) findViewById(R.id.myWebView);
myProgress= (ProgressBar) findViewById(R.id.myProgress);
myWebView.setWebViewClient(new myWebClient());
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.getSettings().setLoadWithOverviewMode(true);
//Other webview settings
myWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
myWebView.setScrollbarFadingEnabled(false);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
myWebView.getSettings().setAllowFileAccess(true);
myWebView.getSettings().setSupportZoom(true);
myWebView.loadUrl(SafeNestConstants.MEDLIFE_URL);
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
{
myProgress.setVisibility(View.VISIBLE);
view.loadUrl(request.getUrl().toString());
return true;
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// TODO Auto-generated method stub
myProgress.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url)
{
// TODO Auto-generated method stub
super.onPageFinished(view, url);
myProgress.setVisibility(View.GONE);
}
}
}
Below is my activity_my_webview.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Also let me know if I can provide more information for the same. Thank you.
I use this code to load WebView
web.setWebChromeClient(new WebChromeClient(){
#Override
public void onReceivedTitle(WebView view, String title) {
getWindow().setTitle(title); //Set Activity tile to page title.
}
});
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
This code works but when the title is empty , the webview will show the url of the page in the title. How to solve it?
Do like this...
web.setWebChromeClient(new WebChromeClient(){
#Override
public void onReceivedTitle(WebView view, String title) {
if(title!=null && title!="")
getWindow().setTitle(title); //Set Activity tile to page title.
else
getWindow().setTitle("");
}
});
May it help !
How can I click on a link that is provided in the WebView data that I load?
The WebView data that is load is in HTML format as:
<P CLASS="western" ALIGN=JUSTIFY STYLE="margin-bottom: 0.14in">Further
here</P>
The WebView is placed inside a scroll view and its webClient is as:
webViewClient = new WebViewClient()
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
#Override
public void onLoadResource(WebView view, String url)
{
}
};
webView = (WebView) findViewById(R.id.tos); // Defining the WebView for the terms and conditions and loading the required data
webView.setWebViewClient(webViewClient);
webView.loadData(getResources().getString(R.string.terms_of_service), "text/html", "UTF-8");
The problem is that when I click on the Link no action takes place. How can this be resolved?
use this code to open
WebView webView;//make sure to initialize
webView.setWebViewClient(webViewClient);
WebViewClient webViewClient= new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
return true;
}
#Override
public void onLoadResource(WebView view, String url){
if( url.equals("http://yoururl.com") ){
// do something
}
}
}
I have a webview. My question is, when user clicks to a link in webview, how to continue with my app?
When user clicks to a link, this dialog box appearing:
How can I avoid this dialogbox and continue with my app?
WebView Code:
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl(url);
Edit (MYActivity İn Test project)
package com.mycompany.myapp5;
import android.app.*;
import android.os.*;
import android.webkit.*;
public class MainActivity extends Activity
{
WebView view;
String url="http://google.com";
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
view.setWebViewClient(new WebViewClient()
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
}
}
This SO answer is exactly what you need.
The idea is to set a WebViewClient to your WebView and override shouldOverrideUrlLoading method like below:
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
I hope this helps you!
Here is the complete code from a test project that is running.
The 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"
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="com.test.myapplication.MainActivity">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"></WebView>
</RelativeLayout>
Code in the Activity:
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webview);
String url="http://www.google.com";
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl(url);
}
This works fine in a 4.4 device. Please try this and let me know if you still have the issue.
This is my first question here. I know that this question has been asked before, but I didn't find an answer/solution that really explains the answer for a totally newbie like me.
I am creating an app with a linear layout that has a lot of buttons, each button should drive the user to a different web page. The buttons works well and every buttons goes to its specific web page, but in the default browser, not within the app.
This is my webview.xml file:
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
This is the WebViewActivity.java file:
public class WebViewActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(
"http://egy-tech-droid.blogspot.com.eg/search/label/%D8%AA%D8%B7%D8%A8%D9%8A%D9%82%D8%A7%D8%AA%20%D8%AD%D8%B5%D8%B1%D9%8A%D8%A9");
}
I added the internet permission in the Manifest file:
<uses-permission android:name="android.permission.INTERNET" />
This opens the web page but in the default browser of the device and I want it to open inside my app. Any help? (please give me a detailed answer/explanation)
Add this to your code
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
}
});
You need to set up a WebViewClient in order to override that behavior (opening links using the web browser).
Use this;
webview.setWebViewClient(new WebViewClient());
Android documentation says:
public void setWebViewClient (WebViewClient client)
Sets the WebViewClient that will receive various notifications and
requests. This will replace the current handler.
Enjoy full code :
Oncreate () :
webView = (WebView) findViewById(R.id.webView1);
if(Constants.isNetworkAvailable(mContext)){
webView.setWebViewClient(new MyWebViewClient());
webView.setWebChromeClient(new WebChromeClient() );
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginState(PluginState.ON);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
webView.setInitialScale(30);
webView.loadUrl(url);
}else{
Toast.makeText(mContext, Constants.msgNoInternet, Toast.LENGTH_LONG).show();
}
MyWebViewClient :
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
if (!pDialog.isShowing()) {
pDialog.show();
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
//view.loadUrl(url);
System.out.println("on finish");
if (pDialog.isShowing()) {
pDialog.dismiss();
}
}
}
Kotlin version of Sunny's answer
webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {
view?.loadUrl(request?.url.toString())
return true
}
}
You can't talk about the Web nowadays without considering Javascript. By default, its use in a WebView is not active. To enable Javascript just insert these lines of code:
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
I hope this will help you.
In your web view layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/relay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#c7bbac">
<ImageView
android:id="#+id/txtmain"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/topbar50" />
<ImageView
android:id="#+id/backbutn"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:adjustViewBounds="true"
android:paddingTop="2dp"
android:src="#drawable/backbtn" />
</RelativeLayout>
<WebView
android:id="#+id/webView1"
android:layout_below="#+id/relay"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Webview Button Onclick:
webbutton = (ImageView) findViewById(R.id.web);
webbutton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), WebViewActivity.class);
startActivity(intent);
}
});
Webview Activity:
public class WebViewActivity extends Activity {
private WebView webViewurl;
ImageView back;
AndroidInterface AMW = AndroidInterface.GetInstance();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
back = (ImageView) findViewById(R.id.backbutn);
webViewurl = (WebView) findViewById(R.id.webView1);
webViewurl.getSettings().setJavaScriptEnabled(true);
webViewurl.getSettings().setBuiltInZoomControls(true);
final Activity activity = this;
webViewurl.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
webViewurl.loadUrl("http://example.com");
back.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
finish();
}
});
}
webView = (WebView) findViewById(R.id.youtubelink);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("your url");
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://www.google.co.in");
this code works fine...
Above code opens the link in your App.
