Question

As the title says.

For example:
I have MainActivity and main.xml
main.xml has WebView “@+id/WebView1”.

After opening SecondActivity, I want it to load an URL on the MainActivity’s webview.

Any solutions?

Answer 1

in your MainActivity.java

WebView webView;
static WebView sWebView; // because we will use in static method

put them in oncreate method;

webView = (WebView )findViewById(webview);
sWebView= webView ; 

create the method below

    // it is static because we will call it from second actvity 
    static loadUrl (String Url){
       sWebView.webloadUrl(url);
    }

in the second activiy on create method,

MainActivity.loadUrl("your URL"); // because load url is a statci method, you can call the it from other class.
