HomeActivity contains Two Fragments- Login And Top
Initially it shows top fragment
Login Fragment has a option for registration
After successful registration the user is navigated to login fragment
Now after Login the control must reach to the "Top" and the name of the user has to written in the Navigation Drawer
How to do it?
this is my Drawer .t want to write name of User instead of welcome to Reuz
HomeActivity

I see that you're saving the user details in your local database, and then trying to load the data after the user has successfully logged in. The issue that you're facing is that the TextView is not being updated. One possible solution that you can call the changeLayoutName() method from the onViewCreated() method of the TopMainFragment itself.

Trouble switching fragment view to main view

I am stuck trying to put the content from my fragment into the main view in android studio.
The app compiles and runs. But when I choose an item in the navigation drawer (sliding menu) to the item in the list with the fragment: it is blank.
My fragment contains an embedded YouTube player.
The logCat does not show an error...
From my code - what am I over looking that is wrong??
here is the main Activity:

You need to call super.onCreateView(...) in the fragment's onCreateView method for the fragment to be drawn correctly.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
Also, I'd recommend doing the following, since there are a few logical errors:
View rootView = inflater.inflate(R.layout.fragment_masjidharam, container, false);
YouTubePlayerView youTubePlayerView = null;
// THIS IS ALWAYS FALSE. Comment it out or else it'll never get set.
// if (youTubePlayerView != null)
youTubePlayerView = (YouTubePlayerView) rootView.findViewById(R.id.youtube_player);
// Check for not-null here.
if(youTubePlayerView != null) {
youTubePlayerView.initialize(API_KEY, this);
}

There is also a very basic Navigation drawer. It has nothing on it only text so I am not posting that here because it's pointless
Everything works fine however the only issue is the buttons. I am really new to android. I initially had an onCreate instead of the onStart where the buttons' actions were because it had errors and I was told that It onCreate can only be called once per activity.
If you can give an answer and also provide explanation that would greatly be appreciated to improve my learning.

remove the onStart
and transfer the value to onCreate
it should be like this
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Add this to your onItemClick method of the mDrawerList
if(mDrawerLayout.isDrawerOpen(mDrawerList)) {
mDrawerLayout.closeDrawer(mDrawerList);
}
else {
mDrawerLayout.openDrawer(mDrawerList);
}

I can't find where are you loading fragment in your code but you are probably missing mDrawerToggle.onDrawerClosed(mDrawerLayout); before you replace your fragments.

Android - ActionBarSherlock Navigation Drawer and Fragments with Activities

I am trying to understand how to implement the ActionBarSherlock Navigation Drawer into a project. I have one working with the official Android implementation but I would like it to run at 2.2+ so I am looking into ActionBarSherlock. I have an error under the selectItem(int position) section of the code. I will paste it here:
package com.rufflez.absnavdrawer;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class MainActivity extends SherlockFragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mFragmentTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mFragmentTitles = getResources().getStringArray(R.array.fragments);
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
mDrawerList = (ListView)findViewById(R.id.drawer_list);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mFragmentTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close){
public void onDrawerClosed(View v){
getSupportActionBar().setTitle(mTitle);
supportInvalidateOptionsMenu();
}
public void onDrawerOpened(View v){
getSupportActionBar().setTitle(mDrawerTitle);
supportInvalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null){
selectItem(0);
}
}
#Override
public boolean onPrepareOptionsMenu(Menu menu){
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()){
case android.R.id.home:
if (mDrawerLayout.isDrawerOpen(mDrawerList)){
mDrawerLayout.closeDrawer(mDrawerList);
} else {
mDrawerLayout.openDrawer(mDrawerList);
}
return true;
case R.id.action_settings:
Intent i = new Intent(MainActivity.this, Sources.class);
startActivity(i);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class DrawerItemClickListener implements ListView.OnItemClickListener{
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id){
selectItem(position);
}
}
private void selectItem(int position){
Fragment newFragment = new Fragment_1();
FragmentManager fm = getSupportFragmentManager();
switch(position){
case 0:
newFragment = new Fragment_1();
break;
case 1:
newFragment = new Fragment_2();
break;
case 2:
newFragment = new Fragment_3();
break;
case 3:
newFragment = new Fragment_4();
break;
case 4:
newFragment = new Fragment_5();
break;
}
fm.beginTransaction()
.replace(R.id.content_frame, newFragment)
.commit();
mDrawerList.setItemChecked(position, true);
setTitle(mFragmentTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title){
mTitle = title;
getSupportActionBar().setTitle(title);
}
#Override
protected void onPostCreate(Bundle savedInstanceState){
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig){
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
As I said above, the error is under selectItem and specifically error under new Fragment_1(); and again at new Fragment_1();. The eclipse message is Type mismatch: cannot convert from Fragment_1 to Fragment.
This is Fragment_1.java:
package com.rufflez.absnavdrawer;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class Fragment_1 extends FragmentActivity{
WebView webview;
private String url;
ProgressBar pd = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// pd = (ProgressBar) findViewById(R.id.web_view_progress_bar);
// webview = (WebView) findViewById(R.id.WebView);
webview.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int progress) {
if(progress < 100 && pd.getVisibility() == View.GONE){
pd.setVisibility(View.VISIBLE);
}
pd.setProgress(progress);
if(progress == 100) {
pd.setVisibility(View.GONE);
}
}
});
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
// do your handling codes here, which url is the requested url
// probably you need to open that url rather than redirect:
if (url.startsWith("tel:")) {
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
} else if (url.startsWith("mailto:")) {
url = url.replaceFirst("mailto:", "");
url = url.trim();
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("plain/text").putExtra(Intent.EXTRA_EMAIL, new String[]{url});
startActivity(i);
} else {
view.loadUrl(url);
}
return true;
// then it is not handled by default action
}
});
webview.loadUrl("file:///android_asset/about.html");
}
#Override
public void onBackPressed()
{
if(webview.canGoBack())
webview.goBack();
else
super.onBackPressed();
}
public void setUrl(String url) {
this.url = url;
}
public String getUrl() {
return url;
}
}

I think you are missing a cast, since new Fragment_1() will return class Fragment_1, and not Fragment.

Oh! Fragment_1() is FragmentActivity Which is an Activity different from Fragment!
see it
Dilemma: when to use Fragments vs Activities:

Your fragment isn't a fragment.
Change onCreate to onCreateView and do this code;
public class Fragment_1 extends SherlockFragment{
i think that is the error.
if not, try rebuilding your fragment in this one
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.actionbarsherlock.app.SherlockFragment;
public class Fragment_1 extends SherlockFragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
return inflater.inflate(R.layout.frag1, container, false);
//change frag1 to corresponding XML
}
}
