Remove both this activity because u used only single activity it define activity and two other is fragment.
<activity android:name=".S"/>
<activity android:name=".Sub"/>
and fragment call used below code..
Fragment fragment = new HomeFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

No need to declare fragment on manifest, remove fragment declaration from manifest because you are declare fragment within section in manifest file.

Use getVIew() to find fragment container Id in non static method

I am trying to use the following code
public int id=GeneralPreferenceFragment.getView().getParent().getId();
inside SettingAvtivity/MainActivity .
but it shows following error
Non-static method 'getView()' can not be referenced from a static Context
please help me resolving this issue
following is the method used
public void method1(View view)
{
Button bt1=(Button)findViewById(R.id.button);
bt1.setOnClickListener(new
View.OnClickListener() {
#Override
public void onClick(View view) {
// ViewGroup vg = (ViewGroup) mCurrentFragment.getView().getParent();
Toast.makeText(SettingsActivity.this,"Sound",Toast.LENGTH_SHORT).show();
DataSyncPreferenceFragment fragment;
GeneralPreferenceFragment fragment1;
GeneralPreferenceFragment frag1;
fragment= new DataSyncPreferenceFragment();
fragment1=new GeneralPreferenceFragment();
GeneralPreferenceFragment prefFragment = new GeneralPreferenceFragment();
int id = prefFragment.getView().getParent().getId();
FragmentManager fm=getFragmentManager();
FragmentTransaction ft=fm.beginTransaction();
ft.replace(R.id.layout_1id,fragment);
ft.remove(fragment1);
ft.add(R.id.layout_1id,fragment);
ft.addToBackStack(null);
ft.commit();
}
});
}
if i use an instance of General preferenceFragment then it shows
Cannot resolve getId();

You need to call method getView() from instance of you class GeneralPreferenceFragment. I.e:
GeneralPreferenceFragment prefFragment = new GeneralPreferenceFragment();
// ... some business logic
public int id = prefFragment.getView().getParent().getId();

progress bar for a webview in fragment view

i am trying to make a app for android in eclipse. where i different fragments with webviews in it. but i want to show a progress bar when webview in loading but i could not getting it how to do it i checked many tutorials but failed to do so. let me most activity code here.
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MenuInflater;

//import android.graphics.Bitmap;
//import android.widget.ProgressBar;
//import android.app.ProgressDialog;
//import android.app.Activity;
#SuppressLint("SetJavaScriptEnabled")
public class AdminTab1 extends Fragment {
private WebView webView;
#Override

Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.admintab1, container, false);
webView = (WebView) rootView.findViewById(R.id.webView1);
webView.setWebViewClient(new WebViewClient());
webView.setScrollbarFadingEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setUserAgentString("AndroidWebView");
webView.clearCache(true);
webView.loadUrl("http://ww.google.com");
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.mainmenu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
webView.reload();
break;
case R.id.item2:
webView.goBack();
break;
default:
break;
}
return true;
}
}

You should try this
public class About27Fragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.about_27, container, false);
final WebView webView = (WebView) rootView.findViewById(R.id.webView_about27);
final ProgressDialog dialog = ProgressDialog.show(getActivity(), "", "Please wait, Loading Page...", true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
dialog.show();
}
#Override
public void onPageFinished(WebView view, String url){
dialog.dismiss();
String webUrl = webView.getUrl();
}
});
webView.loadUrl("https://www.google.com.mx");
return rootView;
}
}

WebViewClient has a lot of callback. You should subclass it and override onPageStarted to show and onPageFinished to dismiss it, for instance. Take a look to the doc, here
private class MyWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url,
// here show the dialog
}
public void onPageFinished(WebView view, String url) {
// here dismiss it
}
}
and in onCreateView use it like
webView.setWebViewClient(new MyWebClient());

oncreate
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web_view);
web_view = (WebView) findViewById(R.id.web_view);
pd = new ProgressDialog(Activity.this);
pd.setMessage("Please wait Loading...");
pd.show();
web_view.setWebViewClient(new MyWebViewClient());
web_view.loadUrl("ur site name");
}
WebViewClient
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
if (!pd.isShowing()) {
pd.show();
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("on finish");
if (pd.isShowing()) {
pd.dismiss();
}
}
In this way you can implement Progress Dialog in webview.

Try this to get progress in percentage
myWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different
// scales
//Updaate progress bar here with progress int
}
});
