Have you tried embeding the .swf file in an html file and load this html ?

I added scrolling activity(textscoll) to my Project.So I wanted to add huge text to that activity and several images in between that huge text.So I added string file in string.xml and called it in scrolling activity(content_textscoll.xml)...
My string file
<string name="string_text_file">This is huge text...</string>
My content_textscoll.xml
<TextView
android:layout_width="wrap_content"
android:textColor="#000000"
android:textSize="20dp"
android:lineSpacingMultiplier="1.3"
android:layout_height="wrap_content"
android:layout_margin="#dimen/text_margin"
android:text="#string/string_text_file" />
My problem is,
*I want to add several images in between above text.How to resolve that problem....?
I can add images to drawble folder.How to call them?
*How to add html links or other activity links
make web view :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="abhiandroid.com.htmlexample.MainActivity">
<WebView
android:id="#+id/simpleWebView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="20dp" />
</RelativeLayout>
make assest folder if not exist and create new html file there with any name you want, then put your text and images there like this :
<p>in this tag (p tag) put your text </p>
<img>in this tag (img tag) put your images </img>
in your activity make something like this :
WebView webView;
public String fileName = "yourAssestFileName.html";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// init webView
webView = (WebView) findViewById(R.id.simpleWebView);
// displaying content in WebView from html file that stored in assets folder
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/" + fileName);
}
I try to load youtube website using WebView in Android application. Need to load whole youtube site to WebView (not only one certain video url). It means user select video on youtube site and then play. But the playing of video is jammming. Is it wrong way using youtube inside application ?
I am using this code: webView.loadUrl(url);
pls Follow this code it will work for you
MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
private WebView mWebview ;
private String youtubeUrl = "https://www.youtube.com/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebview = (WebView) findViewById(R.id.youtubeWebView);
mWebview.loadUrl(youtubeUrl);
mWebview.getSettings().setJavaScriptEnabled(true);
}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/youtubeWebView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.constraint.ConstraintLayout>
and add Internet Permission inside your Manifest file
AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
it will looks like this in the below pic.
you can load any url into web view and add the internet permission inside your app's manifest file and use like below code --
yourWebView.loadUrl(youtubeUrl);
this works for me , i am sure it will work mate
I added every thing to my app but it keeps opening the page that said page not found even if i add a URL for google or any other link.
I look at most of the solutions for the same question but none of them worked (allowing internet access, allowing local access, changing the link to android asset, ......)
Any way hers my code hope you can help:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String url="http://www.google.com";
WebView home = (WebView) this.findViewById(R.id.homeweb);
home.loadUrl(url);
home.setWebChromeClient(new WebChromeClient());
home.clearCache(true);
home.getSettings().setAppCacheEnabled(false);
}
}
And here is 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:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="com.example.alex.myapplication.MainActivity">
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/homeweb" />
</RelativeLayout>
I know it's very simple in code but I'm still new to programming HTML in Android.
Just follow below code for showing html code in browser,
WebView view = new WebView(getActivity());
view.setVerticalScrollBarEnabled(false);
((LinearLayout)rootView.findViewById(R.id.text_about)).addView(view);
view.loadData(Html.fromHtml(put your url here), "text/html; charset=utf-8", "utf-8");
put html file in assets folder then write following code in activity
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("file:///android_asset/your_file_name.html");
remove these line from xml code
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
also remove code from activity
home.setWebChromeClient(new WebChromeClient());
home.clearCache(true);
home.getSettings().setAppCacheEnabled(false);
Programs run from top to bottom.So your problem is just the arrangement of your code.
In the onCreate method, use this code:
setContentView(R.layout.activity_main);
webView = (webView) findViewById(R.id.webView_id);
webSettings websettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
//After configuring all the required settings then you load your url
webView.loadurl("https://www.google.com");
webView.setWebViewClient(new webViewClient());
I have an Android webView which loads a remote web page. As the code of this page is controlled by a colleague I can ask him to change it but I would prefer to find a solotion totally on client side.
For reasons regarding traffic and performance we want to store our css and javascript files locally on the client and not load them from the server.
What I came up with are two ideas but none of them worked out so far.
Store all the files in the asset folder and have the html refer to them
Problem: The webview seems to be not allowed to access "file:///..." urls
Question: Is there a way to work around this issue?
Just ignore all those references in the html and just inject all those files after loading them in the webview
Question: Just how do I add those files (.css / .js) to my already loaded html?
You can build a local WebView in the following way
The Activity (LocalWebviewActivity.java)
The Layout (activity_localwebview.xml)
The Assets folder (in the root of "assets" folder, create the folder "css" and place "style.css" in here)
You refer to JS files the same way you refer to CSS StyleSheets
LocalWebviewActivity.java
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class LocalWebviewActivity extends Activity {
WebView myWebView;
StringBuilder mySBcontent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_localwebview);
myWebView = (WebView) findViewById(R.id.webkit);
mySBcontent = new StringBuilder();
mySBcontent.append("<html>");
mySBcontent.append("<head>");
mySBcontent.append("<link type='text/css' rel='stylesheet' href='css/style.css'>");
mySBcontent.append("</head>");
mySBcontent.append("<body>");
mySBcontent.append("<h1>My Heading</h1>");
mySBcontent.append("<p>My HTML content</p>");
mySBcontent.append("<p><img style='width:150px;' src='myImg.png' /></p>");
mySBcontent.append("</body>");
mySBcontent.append("</html>");
myWebView.loadDataWithBaseURL("file:///android_asset/", mySBcontent.toString(), "text/html", "UTF-8", "");
}
}
activity_localwebview.xml
<?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/webkit"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
I am looking for a way to load an external website within a page in the app.
For example have a website link for a company on the main screen and when clicked have the transition effect to another page that displays the company website, but also allows you to include the header and footer for the page. You can also include options to go back, or other links.
I believe this is possible, so any help with this would be great. Thanks,
I believe you are talking about Android's WebView class.
http://developer.android.com/reference/android/webkit/WebView.html
A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.
http://developer.android.com/resources/tutorials/views/hello-webview.html
You just need to use the webview view. After that it's pretty simple to place the view wherever you want and send it to any url you'd like.
WebView mWebView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
I currently am using this method and it works.
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class ThirdActivity extends Activity
{
WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.html_view);
webview = (WebView)findViewById(R.id.viewHTML);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("https://twitter.com/LaserPros");
}
}
don't forget your xml file mine is named html_view it has a webview in it with the id of viewHTML the file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/viewHTML"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
in the class activity the important thing to (and what most people miss when giving an answer) is to set your web view as the WebClient otherwise your phone will want to open the url in a external browser.
