import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.TextView;
public class HelloWebView2Activity extends Activity {
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
/** Called when the activity is first created. */
Button ileriTusu,geriTusu,DurTusu,GitTusu,AramaTusu;
TextView AdresCubugu;
WebView WebEkrani;
String ilksayfa;
String sayfa;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ileriTusu=(Button)findViewById(R.id.ileritusu);
geriTusu=(Button)findViewById(R.id.geritusu);

AdresCubugu=(TextView)findViewById(R.id.Adres);
WebEkrani=(WebView)findViewById(R.id.Ekran);
WebEkrani.getSettings().setJavaScriptEnabled(true);
WebEkrani.setWebViewClient(new HelloWebViewClient());
sayfa=(String) AdresCubugu.getText();
GitTusu.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
WebEkrani.loadUrl((String) AdresCubugu.getText());
WebEkrani.setWebViewClient(new HelloWebViewClient());
return true;
}
});
geriTusu.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if(WebEkrani.canGoBack())
WebEkrani.goBack();
return true;
}
});
ileriTusu.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if(WebEkrani.canGoForward())
WebEkrani.goForward();
return true;
}
});
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && WebEkrani.canGoBack()) {
WebEkrani.goBack();
return true;
}

WebEkrani.goForward();
