推荐答案

我认为在您的代码中您错过了这个抑制器

I think in your code you missed this suppressLint

@SuppressLint("SetJavaScriptEnabled")

@SuppressLint("SetJavaScriptEnabled")

尝试像这样更改代码..这样，我就可以加载您的[页面]

Try to change your code like this.. in this way i am able to load your [page]

private WebView mWebview=null ;

 @SuppressLint("SetJavaScriptEnabled")
   @Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    mWebview  = new WebView(this);

    mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript

    final Activity activity = this;

    mWebview.setWebViewClient(new WebViewClient() {
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
        }
    });



    mWebview.loadUrl("http://fahrikayahantaksi.com/");
    setContentView(mWebview );

}

不要忘记在清单中添加Internet权限！

Don't forgot to add the Internet permission in your manifest !!

uses-permission android:name="android.permission.INTERNET" />
