Pop up window from menu overflow item selected android

I am trying to display a pop up window when i click on a menu overflow item. I have written some code also for that. But it outputs nothing.
Here is some code:
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case R.id.settings_id:
displayPopupWindow();
return true;
case R.id.about_us_id:
return true;
case R.id.logout_id:
startActivity(new Intent(HomePage.this,MainActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void displayPopupWindow() {
PopupWindow popup = new PopupWindow(this);
View layout = getLayoutInflater().inflate(R.layout.popup, null);
popup.setContentView(layout);
popup.setOutsideTouchable(true);
popup.setFocusable(true);
popup.showAtLocation(layout, Gravity.CENTER, 0, 0);
}
My Xml file Code is below:

Navigation drawer implementation with activities using inheritance

In my app I have to use navigation drawer with all activities. So I have created a base activity called DrawerActivity. I wrote the code for navigation drawer in DrawerActivity and then extended the UserDashBoardActivity from DrawerActivity.
The problem is that DrawerActivity properties aren't executed in UserDashBoardActivity. I can't interact with DrawerActivity in UserDashBoardActivity. Here that drawer menu is in ActionBar in all the activities.
This is my DrawerActivity
public class DrawerActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_list_view);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerItems = getResources().getStringArray(R.array.navigation_drawer_items_array);
//mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(
this, R.layout.drawer_list_items, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout, R.drawable.ic_menu,
R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View view) {
invalidateOptionsMenu();
}
public void onDrawerClosed(View view) {
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
for (int index = 0; index < menu.size(); index++) {
MenuItem menuItem = menu.getItem(index);
if (menuItem != null) {
// hide the menu items if the drawer is open
menuItem.setVisible(!drawerOpen);
}
}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
switch (position) {
case 0: {
Intent intent = new Intent(DrawerActivity.this, UserDashBoardActivity.class);
startActivity(intent);
break;
}
case 1: {
Intent intent = new Intent(DrawerActivity.this, AdmissionActivity.class);
startActivity(intent);
break;
}
default:
break;
}
mDrawerLayout.closeDrawer(mDrawerList);
}
}
This is my UseDashBoardActivity
public class UserDashBoardActivity extends DrawerActivity {
private Context context;
private ImageButton searchBtn;
private ImageButton favBtn;
private ImageButton profileBtn;
private ImageButton reminderBtn;
private ImageButton logoutBtn;

}
#Override

super.onResume();
AppActivityStatus.setActivityStarted();

}
#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_user_dash_boad, menu);
return true;
}
// delete the selected event from event list added here
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_notify:
return true;
case R.id.action_favourite:
return true;
case R.id.action_navigation:
}
return super.onOptionsItemSelected(item);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().setCustomView(R.layout.action_bar_layout);
setContentView(R.layout.user_dash_board);
context = getApplicationContext();
searchBtn = (ImageButton) findViewById(R.id.search_btn);
favBtn = (ImageButton) findViewById(R.id.fav_btn);
profileBtn = (ImageButton) findViewById(R.id.profile_btn);
reminderBtn = (ImageButton) findViewById(R.id.reminder_btn);
notificationBtn = (ImageButton) findViewById(R.id.notification_btn);
logoutBtn = (ImageButton) findViewById((R.id.logout_btn));
final EditText Search = (EditText)findViewById(R.id.emailAddress);
mDrawerList = (ListView)findViewById(R.id.drawer_layout);
searchBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent regAct = new Intent(getApplicationContext(), SearchActivity.class);
// Clears History of Activity
regAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(regAct);
}
});
favBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View arg0){
Intent tabAct = new Intent(getApplicationContext(),TabHostActivity.class);
tabAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(tabAct);
}
});
profileBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View arg0) {
Intent tabAct = new Intent(getApplicationContext(),AboutCollegeActivity.class);
tabAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(tabAct);
}
});
}
}
This is my actionbar xml
<?xml version="1.0" encoding="utf-8"?>
<menu

The UserDashboard activity is executed as it is but I need the property of DrawerActivity to be executed along with this activity. How to do it?

Let the parent Activity add the required ViewGroup as child of the FrameLayout. To achieve this, use the following method for DrawerActivity:
protected void addToContentView(int layoutResID)
{
// as part of onCreate() we had already
// setContentView(R.layout.activity_drawer);
if (layoutResID >= 0)
{
Toast.makeText(this, "activity content found", Toast.LENGTH_LONG).show();
FrameLayout fl = (FrameLayout)findViewById(R.id.activity_frame);
View.inflate(this, layoutResID, fl);
}
else
{
Toast.makeText(this, "activity content missing", Toast.LENGTH_LONG).show();
}
}
Then, in the onCreate() method of the child Activity:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// call this instead of setContentView()
addToContentView(R.layout.activity_user_dashboard);
// put here your code as before...
}

Drawer's layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
<!--you need to add everything to this frameLayout then only you will be able to access Navigation DrawerLayout-->
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</LinearLayout>
<ListView
android:id="#+id/navigation_list"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:background="#color/white"
/>
</android.support.v4.widget.DrawerLayout>
The Activity with Drawer:(Only important code is shown)
public abstract class BaseDrawerLayoutActivity extends AppCompatActivity implements OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout_activity);
//rest of the things
//NOTE: loadNavMenu is abstract so that you can implement it in other activities as per you need, otherwise remove this and load it here itself
loadNavMenu();
}
protected abstract void loadNavMenu();
// call this method whenever you enter new activity and load the fragment here.
public void showFragment(Fragment object, String title) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment, object);
transaction.commit();
}}
Those activities which need the drawer menu can inherit above class. Not inflate all the layout's inside FrameLayout only.
public class MainActivity extends BaseDrawerLayoutActivity {
public static final String TAG = OLMSActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//the method below will call the BaseDrawerLayoutActivity method and change the fragment for you to see.
showFragment(new MyProfileFragment(), "My Profile");
}
#Override
protected void loadNavMenu() {
NavItems.clear();
//load your menu items
}
private void loadNavFavourites(){
//todo
}}
MyProfileFragment is just a class with fragment and this one call inflate a layout in its OnCreateView method.

The Adapter that you are setting is wrong you are using an ArrayAdapter but you should be actually using an ActionBarDrawerToggle like this
private void initDrawer() {
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
}
};
drawerLayout.setDrawerListener(drawerToggle);
}
if you need furthur assistance refer this link http://developer.android.com/training/implementing-navigation/nav-drawer.html

You need to add listview in navigation drawer like below.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/activity_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<!-- The navigation drawer -->
<android.support.design.widget.NavigationView
 android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start" >
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

In your drawer activity (DrawerActivity.class)
public class DrawerActivity extends ActionBarActivity
Replace the actionbaractivity with appcompactability. I think this should solve your problem.

Android: setVisibility not setting View to visible

I'm using minSDK = 8 and targetSDK = 17
At activity start, my 3 screens (3 different Views) are set to invisible in the XML layout. In onResume, I call setScreen(1), which starts an animation that sets View 'wait' to visible. However, at line 34 where 'wait' is set to visible, nothing happens. If I remove the comment // from line 43 where 'main' is set to invisible, 'wait' becomes visible.
Why does 'wait' not appear when line 43 is commented out? Why does it take setting the already invisible 'main' View to invisible for 'wait' to appear?

Your UI is not laid out until after onCreate(). Try moving the animations to onStart() or better, use a ViewTreeObserver to start them once layout is complete
