하나의 webview를 통해 내 조각 내 웹 페이지 열기

Question

하나의 webview를 통해 내 조각 내에서 웹 페이지를 열려고하는데 문제는 그럴 수 없다는 것이고 불행히도 응용 프로그램을 닫았습니다.

별관 내가 일하고있는 코드.

어떤 제안이나 도움이 필요합니까?

모든 것에 대해 감사드립니다.

된 .java

package com.example.dona1click; 

import android.app.Fragment; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 

public class Patrocinadores extends Fragment { 

    WebView mWebView; 

    @Override 
    public View onCreateView(LayoutInflater inflater, 
      ViewGroup container, Bundle savedInstanceState) { 

     View x = inflater.inflate(R.layout.nosotros, container, false); 

     String url = "10.1.1.8/dona1clickmobile/index.php"; 

       // or 
     // WebView wv = (WebView)findViewById(R.id.my_webview); 

     mWebView.loadUrl(url); 
     mWebView.setWebViewClient(new WebViewClient() { 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url); 
       return true; 
      } 
     }); 

     return x; 
    } 
}

Answer 1

이 당신의 mWebView 이제까지 아무것도에 할당되어 있습니까? findViewById(R.id.my_webview);을 호출하여 웹보기를 지정한 코드를 주석 처리 한 것 같습니다. 이 경우 변수 이름이 다릅니다.

mWebView를 지정해야합니다. 또한, 당신이 팽창시키고있는 레이아웃 파일에 webview가 있어야합니다.

nullPointerException을 던지는 가장 빠른 방법은 값이 할당되지 않은 변수로 작업을 시도하는 것입니다.

WebView mWebView; 

@Override 
public View onCreateView(LayoutInflater inflater, 
     ViewGroup container, Bundle savedInstanceState) { 
    View x = inflater.inflate(R.layout.nosotros, container, false); 
    mWebView = (WebView) findViewById(R.id.my_webview); 

    String url = "10.1.1.8/dona1clickmobile/index.php"; 
    // probably a good idea to check it's not null, to avoid these situations: 
    if(mWebView != null){ 
     mWebView.loadUrl(url); 
     mWebView.setWebViewClient(new WebViewClient() { 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url); 
       return true; 
      } 
     }); 
    } 

    return x;
