How to use webView in read mode kotlin?

I have an app and i want to open the URL with Reading Mode
Without ads or something the reader don't need to see
How can i do that haw can i enable the reading mode on in kotlin ?

Try it with WebView,
In .xml file add this code:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
And inside activity(or fragment)
import android.os.Bundle;
import android.webkit.WebView;
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.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
}
}

WebView example android

There is a error in mView, I need solution
package com.example.account;
import android.app.Activity;
import android.os.Bundle;
public class WebView extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
}
}
My xml
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
Cannot cast from view to webview
WebView mView = (WebView) findViewById(R.id.webView1)

Try this layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
give me feedback on this.
Update:
You should change your Activity name with Different one. or defined your WebView with different name like:
WebView mView2 = (WebView) findViewById(R.id.webView1)

You are using your activity name as WebView. This name is already used by SDK API. This is the reason it is giving you error.
To solve it, just rename your WebView.java file to some another name like MyWebView.java then your problem will surely solve.
To safely rename your .java file, Just go to packageexplorer , select WebView.java and press F2, and give new name.

Try this, it may help
1 . Using Eclipse, create a new Android project and name it as WebView.
2 . Add the following statements to the main.xml file:
<?xml​ version=”1.0” ​encoding=”utf-8”?>
<LinearLayout ​xmlns:android=”http://schemas.android.com/apk/res/android” ​​​​android:orientation=”vertical” ​​​​
android:layout_width=”fill_parent” ​
​​​android:layout_height=”fill_parent” ​​​​>
<WebView
android:id=”#+id/webview1” ​​
​​android:layout_width=”wrap_content” ​
​​​android:layout_height=”wrap_content” />
</LinearLayout>
3 . In the MainActivity.java file, add the following statements in bold:
package​ com.emergingandroidtech.WebView;
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(); ​​
​​​​​​webSettings.setBuiltInZoomControls(true);
​​​​​​​​wv.loadUrl( ​​​​​​​​“www.google.com”);
​​​​}
}
4. Don't forget to give the internet permission in manifest file
Thank you

You should keep webview inside any parent view

Do not use reserved words as your variable, class and method name.
Here, WebView is reserved or already used by SDK. If you use that word again, Compiler will get confused.
activity_main.xml
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity
{
private WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview=(WebView)findViewById(R.id.webview);
//loads androidride homepage to webview
webview.loadUrl("https://www.androidride.com");
}
}

Error using basic webview - Android

I am trying out a very simple webview application on Android. While the program builds OK, there are run-time errors that I cannot decode. The layout:
<?xml version="1.0" encoding="utf-8" ?>
<Webview xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/helloWebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
The code:
/* Program to create sample webview.
* Steps:
* 1. Create webview.
* 2. Show some website in it.
* 3. Show some transitions as well.
*/
package com.sriram.hellowebview;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.webkit.WebView;
public class helloWebview extends Activity {
WebView myWebview;
String url = "http://www.google.com";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hello_webview);
Log.v(this.toString(), "Starting activity.");
myWebview = (WebView) findViewById(R.id.helloWebview);
Log.v(this.toString(), "Getting settings.");
//myWebview.getSettings().setJavaScriptEnabled(true);
Log.v(this.toString(), "Loading URL now.");
myWebview.loadUrl(url);
Log.v(this.toString(), "Loaded URL.");
//open all links within the same webview.
//myWebview.setWebViewClient(new WebViewClient());
//Log.v(this.toString(), "All done here.");
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_hello_webview, menu);
return true;
}
}
The error observed:
03-24 14:48:27.618: E/AndroidRuntime(388): Uncaught handler: thread main exiting due to uncaught exception
03-24 14:48:27.658: E/AndroidRuntime(388): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.sriram.hellowebview/com.sriram.hellowebview.helloWebview}: android.view.InflateException: Binary XML file line #3: Error inflating class Webview
I have come across similar errors that detail OutOfMemoryExceptions in large projects, but since the above code is all there is to the project, this does not seem a likely explanation.

There is typo mistake in your layout: WebView need to be written in CamelCase. There isn't such view as 'Webview'. So your layout should look as:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/helloWebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />

You are receiving this error as you are not having any parent layout for webview.
Change your xml file as:
<?xml version="1.0" encoding="utf-8" ?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<WebView
android:id="#+id/helloWebview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
Hope it helps.

Basic app with webview not working - FC on start

I am trying to create a simple webview and I am getting FC on each start.
Here is my MainActivity.java file:
package com.jerdog.apps;
import android.app.Activity;
import android.os.Bundle;
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 myWebView = (WebView) findViewById(R.layout.main);
myWebView.loadUrl("http://www.google.com");
}
}
and here is my res/layout/main.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
I am including my logcat from the moment I press Run in Eclipse at pastebin
http://pastebin.com/5trRw9Bd

This line:
WebView myWebView = (WebView) findViewById(R.layout.main);
is incorrect, and myWebView is null. Thus the following line throws the NullPointerException
Change the line to:
WebView myWebView = (WebView) findViewById(R.id.webview);
findViewById takes the id of the View you wish to find as an input, however you were passing in your layout. Changing this to the id of the WebView element from your main.xml file should fix the issue. There is a tutorial if you need a reference implementation.
