所以，我开始开发一个使用一个webview的应用程序。该应用程序有一个登录按钮，如果您按下该按钮，则会将您引导至名为csgolounge.com的网站的Steam登录页面。我还实现了一个导航抽屉，您可以使用该抽屉浏览该网站的不同菜单。五个小时前，我遇到了这个问题，当我登录Steam并通过导航抽屉切换到该网站的另一个菜单时（例如从www.csgolounge.com到www.csgolounge.com/myprofile），我就是这样。没有登录当我转动移动设备时，会话也会发生变化！到现在为止，我无法弄明白，在stackoverflow上我也没有可行的解决方案！
我猜我的问题与cookie有关，所以请帮帮我:(
这是MainActivity：

webview = (WebView) findViewById(R.id.webView);

我的LoginActivity，它只有一个按钮，当你点击它时，会启动HomeActivity：
public class LoginActivity extends ActionBarActivity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
final Button button = (Button) findViewById(R.id.btn_SignIn);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent logIn = new Intent(LoginActivity.this, HomeActivity.class);
startActivity(logIn);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_login, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
我的WebViewClient（mViewClient）只是覆盖了一些函数，以便在加载时能够阻止csgolounge.com网站中的不同元素：
public class mWebViewClient extends WebViewClient {
public mWebViewClient() {
}
public boolean shouldOverrideUrlLoading(WebView webview, String s) {
webview.loadUrl(s);
return true;
}
public void onPageFinished(WebView view, String url){
super.onPageFinished(view, url);
}
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
if (HomeActivity.itemSelected == false && url.contains("csgolounge.com") && !url.contains("steamcommunity.com")) {
view.loadUrl("javascript:(function() { " +
"document.getElementsByTagName('section')[1].style.display = 'none'; " +
//"document.getElementsByTagName('header')[0].style.display = 'none'; " +
"document.getElementsByTagName('div')[4].style.display = 'none'; " +
"document.getElementsByTagName('aside')[0].style.display = 'none';" +
"})()");
}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 0) {
}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 1) {
}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 2) {
}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 3) {
view.loadUrl("javascript:(function() { " +
"document.getElementsByTagName('section')[0].style.display = 'none'; " +
"document.getElementsByTagName('header')[0].style.display = 'none'; " +
"document.getElementsByTagName('div')[4].style.display = 'none'; " +
"document.getElementsByTagName('aside')[0].style.display = 'none';" +

}

}

}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 7) {
}
else if (HomeActivity.itemSelected == true && HomeActivity.itemSelectedNumber == 8) {
}
}
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
//Users will be notified in case there's an error (i.e. no internet connection)
Toast.makeText(view.getContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
}
ObjectDrawerItem类：
public class ObjectDrawerItem {
public int icon;
public String name;
// Constructor.
public ObjectDrawerItem(int icon, String name) {
this.icon = icon;
this.name = name;
}
}
DrawerItemCustomAdapter类：
public class DrawerItemCustomAdapter extends ArrayAdapter<ObjectDrawerItem> {
Context mContext;
int layoutResourceId;
ObjectDrawerItem data[] = null;
public DrawerItemCustomAdapter(Context mContext, int layoutResourceId, ObjectDrawerItem[] data) {
super(mContext, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.mContext = mContext;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItem = convertView;
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
listItem = inflater.inflate(layoutResourceId, parent, false);
ImageView imageViewIcon = (ImageView) listItem.findViewById(R.id.imageViewIcon);
TextView textViewName = (TextView) listItem.findViewById(R.id.textViewName);
ObjectDrawerItem folder = data[position];
imageViewIcon.setImageResource(folder.icon);
textViewName.setText(folder.name);
return listItem;
}
}

答案 0 :(得分：0)
碎片的东西让我失望了，但它看起来像是因为网址以www开头，所以它认为它是一个不同的域。将其更改为webview.loadUrl("http://csgolounge.com/myprofile");可以解决我的问题。
