How do I open a webview in another activity using editText for the url and a button click

Question

MainActivity.java

public class MainActivity extends Activity {

    WebView web1;
    EditText ed1;
    Button bt1;
    String Address;
    ProgressBar pbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        final Context context = this;
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        web1 = (WebView) findViewById(R.id.webView1);
        ed1 = (EditText) findViewById(R.id.editText1);
        bt1 = (Button) findViewById(R.id.button1);

        pbar.setVisibility(View.GONE);

        bt1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(context, WebViewActivity.class);
                startActivity(intent);


                Address = "http://" + ed1.getText().toString();
                WebSettings webSetting = web1.getSettings();
                webSetting.setBuiltInZoomControls(true);
                webSetting.setJavaScriptEnabled(true);
                setContentView(R.layout.activity_main);

//below gives me this error stating new WebViewClient can not resolve.

                web1.setWebViewClient(new WebViewClient());

                web1.loadUrl(Address);

            }
        });
    }
}

WebViewActivity.java

public class WebViewActivity extends Activity {


    WebView web1;

    String Address;
    String add;
    ProgressBar pbar;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_new);

        web1 = (WebView)findViewById(R.id.webView1);

        pbar = (ProgressBar)findViewById(R.id.progressBar1);
        pbar.setVisibility(View.GONE);

        web1.setWebViewClient(new WebViewActivity.WebViewClient());

    }


    public class WebViewClient extends android.webkit.WebViewClient
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {

            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
            pbar.setVisibility(View.VISIBLE);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            // TODO Auto-generated method stub
            view.loadUrl(url);
            return true;
        }
        @Override
        public void onPageFinished(WebView view, String url) {

            // TODO Auto-generated method stub

            super.onPageFinished(view, url);
            pbar.setVisibility(View.GONE);
        }

    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && web1.canGoBack()) {
            web1.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
}

Take a look at http://stackoverflow.com/questions/2091465/how-do-i-pass-data-between-activities-on-android, you can pass the URL between activities. — Grender, Oct 27 '16 at 18:37
Are you sure it can't resolve? You have an `import android.webkit.WebViewClient`, right? — OneCricketeer, Oct 27 '16 at 18:40
Maybe you shouldn't name **your** class as `WebViewClient` when there already is a conflicting name of `android.webkit.WebViewClient` — OneCricketeer, Oct 27 '16 at 18:40
Okay, so show the logcat. http://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this — OneCricketeer, Oct 27 '16 at 18:46
@MarkAcquaisie It can be important to provide the full text of the error message with your question, please try to do that. — Tibrogargan, Oct 27 '16 at 18:52

Use Intent to pass the url as string to the webview activity:

Intent intent = new Intent(context, WebViewActivity.class);
intent.putExtra("URL",url)
startActivity(intent);

And Access it in WebViewActivity onCreate by:

Intent in = getIntent();
String url = in.getStringExtra("URL");

Now pass this url in

weview.loadurl(url);

MainActivity

public class MainActivity extends AppCompatActivity {

Button b1;
EditText ed1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    b1 = (Button) findViewById(R.id.button);
    ed1 = (EditText) findViewById(R.id.editText);

    b1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String url = ed1.getText().toString();
            Intent intent = new Intent(getApplicationContext(), WebViewActivity.class);
            intent.putExtra("URL", url);
            startActivityForResult(intent, 1);

        }
    });
}


}
