I can't click on my navigation drawer

I am struggling to get the Navigation drawer items to register and start and intent for a new activity. The drawer opens fine and is displayed correctly but nothing happens when I click on the items in the list. Here is my code

}

try change your code inside onNavigationItemSelected to this:
switch (item.getItemId()){
case R.id.nav_alarm:
//do stuff
Intent goToNextActivity = new Intent(getApplicationContext(), Main2Activity.class);
startActivity(goToNextActivity);
break;
}
FragmentTransaction ft =getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_main,fragment);
ft.addToBackStack(null);
ft.commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;

You should check your onNavigationItemSelected(MenuItem item) method because while replacing the fragment you initailized you fragment null like Fragment fragment = null; .So, for replace the fragment you need to take actual fragment instead of null fragmnet.
You may go through about the fragments here.
`

Change the flow of the code as below:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
item.setCheckable(false);
Fragment fragment=null;
switch (item.getItemId()) {
case R.id.navigation_home:
fragment = new HomeFragment();
break
}
loadHomeFragment(fragment);
mDrawerLayout.closeDrawer(GravityCompat.START);
return true;
}
private void loadHomeFragment(Fragment fragment) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
fragmentTransaction.replace(R.id.frame, fragment);
fragmentTransaction.commitAllowingStateLoss();
}

Call a Fragment implements View.OnClickListener in a drawermenu

}
}
There my errors:
"Error:(81, 28) error: incompatible types: LoginFragment cannot be converted to RegisterFragment"
How could I call this fragment ? Should I modify everything ?

The wrong thing is that you are try to cast all your fragments to RegisterFragment, and they do not extend that class.
You should cast them to Fragment:
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new ConnectFragment();
break;
case 1:
fragment = new FixturesFragment();
break;
case 2:
fragment = new TableFragment();
break;
case 3:
fragment = new LoginFragment();
break;
case 4:
fragment = new RegisterFragment();
break;
default:
break;
}
...
}

I have a navigation drawer that when an Item is selected, it loads the new fragment but never closes the drawer. My navigation drawer code looks like this:

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.

Hold click menu item different than click?

I currently have a menu that I load into my Toolbar which looks like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"
android:onClick="goToSearch"
android:title="Search"/>
<item android:id="#+id/action_barcode"
android:icon="#drawable/bar"
android:title="barcode"
app:showAsAction="ifRoom"
android:onClick="scanBarcode"/>
</menu>
When you click the barcode icon, it loads my barcode scanning fragment. I want to clean up my toolBar and not have multiple icons up there. Essentially I want my search icon, that opens up when clicked to have two functions.
When clicked open the search bar.
When long pressed, open my barcode scan fragment.
Currently Number one works, looking at how to employ number 2.
This is what my code looks liek for launching the barcode scan fragment and search.

The action bar concept doesn't count on this requirement, so using built-in functionality you'll never be able to achieve what you need.
You can, however, introduce your own custom layout in stock action bar and do whatever you want there. See an example here:

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
}
}
