在Android应用程序中使用WebView？

Question

我已经使用WebView创建了一个应用程序，但我不想退出应用程序。我想在我的应用程序中看到WebView，我仍然希望在应用程序的底部看到我的后退按钮。我怎么能这样做？

 public class MainActivity extends Activity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
   WebView webview = (WebView) findViewById(R.id.webview);
   webview.getSettings().setJavaScriptEnabled(true);
   webview.loadUrl("https://XXXXXXXXXXXXXX.com.tr");

Answer 1

mWebview.setWebViewClient(new WebViewClient() {
        @SuppressWarnings("deprecation")
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
        }
        @TargetApi(android.os.Build.VERSION_CODES.M)
        @Override
        public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
            // Redirect to deprecated method, so you can use it in all SDK versions
            onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
        }
    });

    mWebview .loadUrl("http://www.google.com");
