如何加載您在網頁視圖中打開的最後網址

Question

我：

package my.domain.app;  

import android.app.Activity; 
import android.os.Bundle; 
import android.content.SharedPreferences; 
import android.webkit.*; 



public class MainActivity extends Activity { 
    private WebView webView; 
    private SharedPreferences sPref; 

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

    void someMethod() { 
     WebView webView = (WebView) findViewById(R.id.webView); 
     webView.setWebViewClient(new MyWebViewClient()); 

     String url; 

     if (sPref.contains("PREFS_ID")) 
      url = sPref.getString("PREFS_ID", "DEFAULT_VALUE"); 
     else 
      url = "http://example.com"; 

     WebSettings webSettings = webView.getSettings(); 
     webSettings.setJavaScriptEnabled(true); 
     webSettings.setBuiltInZoomControls(true); 
     webSettings.setAllowContentAccess(true); 
     webSettings.setSupportZoom(true); 
     webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH); 

     MyWebViewClient myWebViewClient = new MyWebViewClient(); 
     webView.setWebViewClient(myWebViewClient); 
     webView.loadUrl(url); 
    } 

    private class MyWebViewClient extends WebViewClient { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      if (!url.equals("YOUR_FIRSTURL")) { 
       sPref.edit().putString(url, "PREFS_ID").commit(); 
      } 
      return true; 
     } 
    } 
} 

我想，他打開http://example.com但如果我去http://example.com/page2，當我重新打開網頁視圖他打開http://example.com/page2 我現在有用更多的細節更新了代碼。

您可以簡單地將您的網址保存到SharedPreferences，然後，如果您的網址存在SharedPreferences重新打開它。

像這樣：

void someMethod() { 
    WebView webView = (WebView) findViewById(R.id.webView); 
    webView.setWebViewClient(new MyWebViewClient()); 

    String url; 

    if (sPref.contains("PREFS_ID")) 
     url = sPref.getString("PREFS_ID", "DEFAULT_VALUE"); 
    else 
     url = "http://example.com"; 

    WebSettings webSettings = webView.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    webSettings.setBuiltInZoomControls(true); 
    webSettings.setAllowContentAccess(true); 
    webSettings.setSupportZoom(true); 
    webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH); 

    MyWebViewClient myWebViewClient = new MyWebViewClient(); 
    webView.setWebViewClient(myWebViewClient); 
    webView.loadUrl(url); 
} 

private class MyWebViewClient extends WebViewClient { 
    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
     if (!url.equals("YOUR_FIRSTURL")) { 
      sPref.edit().putString(url, "PREFS_ID").commit(); 
     } 
     return true; 
    } 
}
