Android - Error in creating Youtube fragment

Android - Error in creating Youtube fragment - java

I'm creating android fragment that can play youtube video by using Youtube API Player. In MainActivity class, I'm getting error that
private void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment =null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new VideoFragment();
break;
case 2:
fragment = new ThirdFragment();
break;
default:
break;
}
Type mismatch: cannot convert from VideoFragment to Fragment
However, when I switch to new code:
private void displayView(int position) {
// update the main content by replacing fragments
VideoFragment fragment =null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new VideoFragment();
break;
case 2:
fragment = new ThirdFragment();
break;
default:
break;
}
This error occur

Fragments and Activities are not the same thing. Activity does not inherit from fragment look at this question.
In the case VideoFragment inherited Fragment, and assuming HomeFragment and ThirdFragment also inherit from Fragment, you first approach should work.

Refresh Navigation Drawer Fragment Android?

I have a question about the navigation drawer fragment. As you know this navigation drawer has multiple sections. Let's say 3 sections (Home, Profile, Log out). My intent is when the user click on Log out, the navigation drawer will refresh itself to (Home, Log in).
I was trying to play with code but I couldn't figured it out..
The files that I have are:
MainActivity.java
public class MainActivity extends ActionBarActivity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {

As you can notice the static variable is_logged_in which is a way to tell me if the user clicked on Log out or not.
I also updated the file NavigationDrawerFragment.java that Android studio created for me at the beginning step when it asked me to choose the type of activity and obviously I did not choose a blank one, I chose the Slide menu one that created this Navigation Drawer Fragment
So the code in NavigationDrawerFragment.java is
public class NavigationDrawerFragment extends Fragment {

*/

Any help will be great from you guys...

What I would try is taking the code you use to set the adapter, and putting it into its own method like this:
private void setupListView(){
if(!GlobalVars.is_logged_in)
{
//the user is NOT logged in
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
//section1: home section2: profile section3:login
getString(R.string.title_section1),
getString(R.string.title_section3),
}));
}
else
{
//the user is logged in
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
//section1: home section2: profile section3:login
getString(R.string.title_section1),
getString(R.string.title_section2),
"Log out",
}));
}
}
Then, inside onCreateView(), replace all that code with the line setupListView(), and then also in the onClickListener for the listview you can check if they clicked logout/logon, and after you change the global variable you can call setupListView() again.

Alright, Thank you so much guys but I solved this issue by calling the part that is responsible for drawing the side menu bar in the MainAvtivity.java like the following
case 2:
objFragment = new Logout();
GlobalVars.is_logged_in = false;
mNavigationDrawerFragment.setupListView();
//mNavigationDrawerFragment.onCreateView(this.getLayoutInflater(), null, null);
break;
so each time the user click on the Log out it will execute the drawing function
Special thanks to #McAdam331

You can just call your item from navigationView object.
navigationView.getMenu().findItem(R.id.navigation_item_2).setTitle("Hello");

Navigation Drawer not opening when I follow tutorial code

I am new to android programming. I was trying to build navigation drawer and I followed this tutorial. The navigation drawer is not getting created and I am getting errors and the app is also terminating.
Below is my code
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
// used to store app title

Try changing if you are using this in your code
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
to
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
Or simply try changing ActionBarActivity to Activity.
You are not setting the click listener...please do this also
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

you are getting and null from this line:
getActionBar().setDisplayHomeAsUpEnabled(true);
you need to check why your action bar is null.
can you post your class itself?
does your class extends ActionBarActivity?

Display logo in ActionBar

I have an action bar but have only been to display the title of application or/and the title of the current fragment activity into it. I would want to display logo in it, and any attempts to add a logo have been unsuccessful.
Below is the code:
public class MainActivity extends ActionBarActivity {
private String[] mOptionMenu;
private DrawerLayout mDrawerLayout;
private RelativeLayout mDrawerRelativeLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mTitleSection;
private CharSequence mTitleApp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView button=(ImageView)findViewById(R.id.logobutton);
mOptionMenu = new String[] { "Opción 1", "Opción 2", "Opción 3" };
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerRelativeLayout = (RelativeLayout)
findViewById(R.id.left_drawer);
mDrawerList = (ListView) findViewById(R.id.list_view_drawer);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
mOptionMenu));
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new FirstFragment();
break;
case 1:
fragment = new SecondFragment();
break;
case 2:
fragment = new ThirdFragment();
break;
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mTitleSection = mOptionMenu[position];
getSupportActionBar().setTitle(mTitleSection);
mDrawerLayout.closeDrawer(mDrawerRelativeLayout);
}
});
mDrawerList.setItemChecked(0, true);
mTitleSection = getTitle();
mTitleApp = getTitle();
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitleSection);
getSupportActionBar().setLogo(R.drawable.logo);
ActivityCompat.invalidateOptionsMenu(MainActivity.this);
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mTitleSection);
ActivityCompat.invalidateOptionsMenu(MainActivity.this);
getSupportActionBar().setLogo(R.drawable.logo);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.action_settings:
Toast.makeText(this, "Settings", Toast.LENGTH_SHORT).show();
;
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
I tried adding this line in the code, but no image is being displayed:
getSupportActionBar().setLogo(R.drawable.logo);
I also have a similar concern, in that I want the logo to be clickable and to direct user to the MainActivity

You have to enable Logo feature on you ActionBar by calling getSupportActionBar().setDisplayUseLogoEnabled(true).

Try this in your OnCreate in this order:
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(true);
getSupportActionBar().setLogo(R.drawable.ic_logo);

In your manifest, you can set android:logo="#drawable/logo" on your <application> node, and/or android:icon="#drawable/icon" for each <activity> node.

In your mainfest file, add under <application>:
android:icon="#drawable/logo"

Fragments and Activities are not the same thing. Activity does not inherit from fragment look at this question. In the case VideoFragment inherited Fragment, and assuming HomeFragment and ThirdFragment also inherit from Fragment, you first approach should work.
