Android : display html data

Question

I want to display the content of an html page and an image to the right of that in my view.

So i have defined my layout as

<ScrollView android:id="@+id/scrllvwNo1"
    android:layout_width="fill_parent" android:layout_height="wrap_content">
    <RelativeLayout android:layout_width="wrap_content"
        android:layout_height="fill_parent" android:background="@drawable/home_bg">
        <ImageView android:id="@+id/aboutcmkimage"
            android:layout_width="wrap_content" android:layout_height="wrap_content"
            android:layout_alignParentRight="true" android:src="@drawable/about"
            android:padding="5dip" />
        <WebView android:id="@+id/aboutcmk" android:layout_width="wrap_content"
            android:layout_height="fill_parent" android:textColor="#000000"
            android:layout_toLeftOf="@+id/aboutcmkimage"
            android:layout_alignParentTop="true" android:layout_alignParentLeft="true" />

    </RelativeLayout>

</ScrollView>

and

I try to load the html page as below

WebView web = (WebView)findViewById(R.id.aboutcmk);
         web.loadData(getString(R.layout.about),"texl/html","utf-8");

in this case i am getting the error "this page contains error at line1 ... "

if I try

web.loadDataWithBaseURL(null,getString(R.layout.about),"texl/html","utf-8",null);

no html output and no error

In both case the image is coming

Can anyone help me in debugging

My html has bullets , so i cannot use textview instead of webview

here is the definition of my htmlstring in xml file

<string name="About"><html><body><b>What is CMK?</b> ......</body></html>

Thanks a lot for the help

I see you have <string name="About"> in your HTML specification. Could you clarify what it is? As far as I know HTML doesn't have any such tag. — Arnab Chakraborty

are you put this line What is CMK? ...... in strings.xml if yes then the correction is in this line web.loadDataWithBaseURL(null,getString(R.layout.about),"texl/html","utf-8",null);

Correct one:

web.loadDataWithBaseURL(null, getString(R.string.About), "text/html", "UTF-8", null);

First of all, if you have saved your HTML specification as a string resource, your should access it as R.string.about and not R.layout.about. Change that, if it still doesn't work, try escaping the less than characters in your string, like this :

<string name="about">&lt;html>&lt;body>&lt;b>What is CMK?&lt;/b> ......&lt;/body>&lt;/html> </string>

I think you will have to escape the less than characters. Before loading the text, Log it. You'll see the problem.

No, problem. If you liked my answer just upvote it. Btw, you can change your choice of the right answer if you want to (not that you have to).

Instead of storing the HTML in strings.xml, you can store it in its own file in the res/raw/ directory. For example, let's say you save the file in res/raw/mypage.html. I haven't tested this, but you should be able to open up raw resources and load them up in a WebView like:

try {
    Resources resources = getResources();
    InputStream inputStream = resources.openRawResource(R.raw.mypage);
    byte[] bytes = new byte[inputStream.available()];
    inputStream.read(bytes);

    String htmlStr = new String(bytes);
    webView.loadData(htmlStr, "text/html", "UTF-8");
} catch(Exception e) {
    //blah
}
