Pop up window from menu overflow item selected android

Pop up window from menu overflow item selected android - 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>
Where is the error? Please help me.

Here is your solution,
MainActivity.java
public class MainActivity extends Activity {
private PopupWindow mPopupWindow;
private Button btnClosePopup;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.items, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch (item.getItemId()) {
case R.id.phone:
Toast.makeText(getBaseContext(), "You selected Phone", Toast.LENGTH_SHORT).show();
break;
case R.id.computer:

}
return true;
}
private void initiatePopupWindow() {
try {
LayoutInflater inflater = (LayoutInflater) MainActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup,
(ViewGroup) findViewById(R.id.popup_element));
mPopupWindow = new PopupWindow(layout, 300, 370, true);
mPopupWindow.showAtLocation(layout, Gravity.CENTER, 0, 0);
btnClosePopup = (Button) layout.findViewById(R.id.btn_close_popup);
btnClosePopup.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mPopupWindow.dismiss();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}

If i delete XML code which is inside DrawerLayout, then it works fine.

you forgot to add drawerLayout.addDrawerListener(toggle); before toggle.syncState();

You dont have objects in your "imageView" array.
Initialize it with values:
for(int i = 0; i < imageView.lenght; i++) imageView[i] = new ImageView(context);
So you can use then properly.

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;
}

Using simple fragments to switch between activities

I have used fragments
activity_fragment_demo.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

OUTPUT SCREEN: -- > WHEN I CLICK BUtton on lefthand side
Similarly for next button
Now HOW CAN I Merge the thow buttons like below
Using fragments i have used .....
If i click on button once Activity-A1 must display in button
below .....
similarly If i click on button again Activity-A2 must display
below
Then if i click on third time ...... Activity-A1 must display
again
A Boolean nature of single button that repeats its cycle !
How to achieve this !

There are many ways to do this but here is a simple solution.
First change activity_fragment_demo.xml
<LinearLayout 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:orientation="vertical"
tools:context=".FragmentDemo" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:visibility="gone"/>
</FrameLayout>
<LinearLayout
android:id="#+id/simple_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</LinearLayout>
</LinearLayout>
next in FragmentDemo.java just change your onClick method like this:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1:
addFragment(new F1(this), false,
FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
b1.setVisibility(View.GONE);
b2.setVisibility(View.VISIBLE);
break;
case R.id.button2:
addFragment(new F2(this), false,
FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
b2.setVisibility(View.GONE);
b1.setVisibility(View.VISIBLE);
break;
default:
break;
}
}

Your Activity could keep track of the state with a boolean. For example like this:
private boolean state = false;
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
state = !state;
if (state) {
addFragment(new F2(this), false,
FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
} else {
addFragment(new F1(this), false,
FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
}
break;
default:
break;
}
}

Custom action bar items listener

I create custom view for action bar: action_bar_bets.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="right"
android:weightSum="2"
android:orientation="horizontal" >
<ImageButton
android:id="#+id/actionBarProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingRight="10dp"
android:src="#drawable/ic_action_user" />
<ImageButton
android:id="#+id/actionBarBets"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingRight="10dp"
android:src="#drawable/ic_action_betslip" />
</LinearLayout>
here is my menu: action_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/mybetsCount"
android:actionLayout="#layout/action_bar_bets"
android:showAsAction="always"/>
</menu>
I create action bar in code:
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
View view = getLayoutInflater().inflate(R.layout.action_bar_bets, null);
actionBar.setCustomView(view)
I tried set OnClickListener to ImageButtons:
like this:
ImageButton profile = (ImageButton) view.findViewById(R.id.actionBarProfile);
profile.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Profile", Toast.LENGTH_SHORT).show();
}
});
and like this:
actionBar.getCustomView().setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.actionBarProfile:
Toast.makeText(getApplicationContext(), "Profile", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
}
});
But nothing happened
Can you help me to fix this problem?
ADD
Also in this class i have ListNavigation
PackageManager pm = getPackageManager();
String label;
try {
ActivityInfo activityInfo = pm.getActivityInfo(getComponentName(),
0);
label = activityInfo.loadLabel(pm).toString();
} catch (NameNotFoundException e) {
label = null;
e.printStackTrace();
}
String[] navigations = { label, "Sports", "Profile" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
getBaseContext(), R.layout.custom_spinner_title_bar,
android.R.id.text1, navigations);
adapter.setDropDownViewResource(R.layout.custom_spinner_title_bar);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
ActionBar.OnNavigationListener navigationListener = new OnNavigationListener() {
#Override
public boolean onNavigationItemSelected(int itemPosition,
long itemId) {
switch (itemPosition) {
case 1:
Intent intent = new Intent(getApplicationContext(),
MainActivity.class);
startActivity(intent);
break;
case 2:
intent = new Intent(getApplicationContext(),
Activity_profile.class);
startActivity(intent);
break;
default:
break;
}
return false;
}
};
actionBar.setListNavigationCallbacks(adapter, navigationListener);
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.action_bar, menu);
return true;
}

im not sure where you initialize your buttons, but when it is in something like onCreate() then replace
ImageButton profile = (ImageButton) view.findViewById(R.id.actionBarProfile);
with
ImageButton profile = (ImageButton) findViewById(R.id.actionBarProfile);

Try this. This is example with a Switch but it's the same way for other component
getMenuInflater().inflate(R.menu.export, menu);
MenuItem item = menu.findItem(R.id.myswitch);
Switch switchOnActionBar = (Switch)item.getActionView().findViewById(R.id.switchForActionBar);
switchOnActionBar.setOnCheckedChangeListener(this);
SwitchForActionBar is in switch_layout.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:layout_gravity="center_vertical"
android:gravity="center_vertical">
<Switch
android:id="#+id/switchForActionBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="Manuel"
android:textOn="Auto"
android:gravity="center_vertical"
android:thumb="#drawable/switch_thumb"
android:textColor="#color/white"
android:textColorHint="#color/white"
android:background="#android:color/transparent"
android:layout_marginRight="10dp"/>
</RelativeLayout>
And this is the menu layout
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/myswitch"
android:title=""
android:checkable="true"
android:showAsAction="always"
android:actionLayout="#layout/switch_layout"
/>
</menu>

try ontouchlistener for imagebutton :
Change
setOnClickListener(new OnClickListener()
to :
setOnTouchListener(new OnTouchListener()

I found where i has error.
LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.RIGHT | Gravity.CENTER_VERTICAL);
actionBar.setCustomView(view, lp);
and delete this code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.action_bar, menu);
return true;
}
My navigation list overlaps the buttons
Thank you all for the help
