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:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent" android:layout_height="match_parent"
android:background="#color/colorPrimary">
<TextView
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="165dp"
android:id="#+id/textView"
tools:text="This is a Pop Up Window!"
android:textSize="36sp"
android:textStyle="normal|bold"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginLeft="19dp"
android:layout_marginStart="19dp"
android:textAlignment="center"
android:fontFamily="sans-serif" />
</RelativeLayout>

Android: Check multiple items ListView

I am trying to implement multiple items selection in a ListView. The List is managed using the CursoAdapter. I was following the tutorials at http://developer.android.com/guide/topics/ui/menus.html#CAB. However, when I run the app, only 1 item is selected (highlighted). Can you point out, What am I doing wrong?
MainActivity.java
public class MainActivity extends ActionBarActivity {
DbHelper db;
ListView myList;

int checkedCount;

Please comment if I need to add more details.
Edit: I looked at the duplicate question. However, majority of answers suggested using an ArrayAdapter, whereas items in my list are managed using SQLite, and each item consists of 3 separate items (no, text1, text2). How can I make use of an ArrayAdapter here? Also, one highly voted answer says to use CheckedTextView. So shall I use CheckedTextView for all the 3 parts of a list item?

I finally solved this by using a selector. Here is the selector.xml file:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#color/link_text_material_dark"
/>
<item android:state_active="true"
android:drawable="#color/primary_dark_material_dark"
/>
<item android:state_selected="true"
android:drawable="#color/highlighted_text_material_dark"
/>
<item android:state_activated="true" android:drawable="#android:color/white" />
</selector>
The most important one is the state_activated item. It is used to highlight all those items which are selected.
Also, in order to use this selector, add the following line to tasks.xml or wherever you have defined each row (item):
android:background="#drawable/selector"

I have modified you code, added little changes. If you still have issues, please follow the sample in you sdk samples folder it will be in the following location.

How to show Actionbar menu item on top in PreferenceActivity?

Help me out to show Actionbar menu item on the Top of the Actionbar. Without showing on overflow drop down menulist.kindly give me a suggestion to do like that?

Use this in your activity
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
LayoutParams lp = new LayoutParams(
android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.RIGHT
| Gravity.CENTER_VERTICAL);
View customNav = LayoutInflater.from(this).inflate(R.layout.img, null);
EditText et = (EditText) customNav.findViewById(R.id.et);
temppaths = new ArrayList<String>();
Button iv = (Button) customNav.findViewById(R.id.iv);
iv.setClickable(true);
iv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
actionBar.setCustomView(customNav, lp);
actionBar.setDisplayShowCustomEnabled(true);
and xmlLayout name it img.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="wrap_content"
android:gravity="right" >
<EditText android:id="#+id/et"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_marginRight="20dp"
android:gravity="center"
android:layout_gravity="right"
android:hint="info#xxxxxx, 1800xxxxx"
android:background="#FF8000" />
<Button
android:id="#+id/iv"
android:layout_gravity="right"
android:layout_width="150dp"
android:layout_height="match_parent"
android:layout_marginRight="20dp"
android:text="Search"
android:background="#FF8000" />
</LinearLayout >

okk then
add these methods in your activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, 0, 0, "LogOut").setShortcut('0', 'o')
.setIcon(android.R.drawable.ic_menu_edit);
menu.add(0, 1, 0, "Save").setShortcut('1', 's')
.setIcon(android.R.drawable.ic_menu_save);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
Toast.makeText(getApplicationContext(), "Log out clicked", 0).show();
// save();
// showNewOrOpenDialog();
break;
case 1:
Toast.makeText(getApplicationContext(), "Save", 0).show();
// save();
break;
}
return false;
}

Search icon on soft keyboard

I have an ActionLayout for a searchIcon of the MenuItems. This ActionLayout has an AutoCompleteTextView which has imeOption = "actionSearch".
But when i click the menuItems and ActionLayout appears, the soft keyboard pops up, but it still has newline key instead of searchIcon.
Activity code:
private AutoCompleteTextView mEtSearchbar;
private MenuItem mSearchbar;
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.searchIcon:
mEtSearchbar.clearFocus();
(new Handler()).postDelayed(new Runnable() {
public void run() {
mEtSearchbar.dispatchTouchEvent(MotionEvent.obtain(
SystemClock.uptimeMillis(),
SystemClock.uptimeMillis(),
MotionEvent.ACTION_DOWN, 0, 0, 0));
mEtSearchbar.dispatchTouchEvent(MotionEvent.obtain(
SystemClock.uptimeMillis(),
SystemClock.uptimeMillis(), MotionEvent.ACTION_UP,
0, 0, 0));
}
}, 100);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Auto-generated method stub
inflater.inflate(R.menu.m_menu, menu);
mSearchbar = (MenuItem) menu.findItem(R.id.searchIcon);
View actionview = mSearchbar.getActionView();
mEtSearchbar = ((AutoCompleteTextView) actionview
.findViewById(R.id.search_editText));
final ImageView searchImage = ((ImageView) actionview
.findViewById(R.id.search_image));
searchImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
String s = mEtSearchbar.getText().toString();
Intent intent = new Intent(getSherlockActivity(),
SearchActivity.class);
intent.putExtra("search_string", s);
startActivity(intent);
}
});
mEtSearchbar
.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
searchImage.performClick();
return true;
}
return false;
}
