How to convert a Fragment to a Activity Android?

I have a working app using threads in fragments, the thing is I need to change the layout. It's not gonna be a Fragment anymore but a standard Activity.
My big problem is that I don't know exactly where to place what's in "onViewCreated" and "onCreateView" so it's crashing when I call "connect to device" which's placed on "onCreateView". Probably because it's too early or something.
#Nullable
#Override
public View onCreateView(final LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState){
View view;
view = inflater.inflate(R.layout.fragment_home_2, container, false);

//Enable bluetooth and start scanning thread
BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
if (btAdapter != null && !btAdapter.isEnabled()) {
btAdapter.enable();
}

connectedToDevice.setText(getResources().getString(R.string.welcome_to_scopefy));

trying to place at the bottom of "onCreate" it gives me the following error:
PopupWindow $BadTokenException: Unable to add window — token null is not valid

Regarding you error
PopupWindow $BadTokenException: Unable to add window — token null is
not valid
Maybe add that code in the Activity onResume() lifecykle method instead of onCreate if it need to run more then one time
Move the scanningThread, BluetoothAdapter and LocalBroadcastManager LibCore everything to the 'onCreate()' . The 'onCreateView()' should only have the view = inflater.inflate(R.layout.fragment_home_2, container, false);
The onCreate() only initiate stuff hook up local variables views and set clicklisteners. Like all the one-time-stuff. Going from Fragment to Activity is basically almost the same since they have the same lifecykle methods

My app crashes when I return back to my main activity from other activities(StackOverflowError)

My MainActivity contains one mikepenz/MaterialDrawer and one pager view which contains 5 fragments. I am using material drawer to launch other activities but after launching many activities and coming back to my base Main activity the below crash occurs.
I have no clue to find the actual root cause of this issue. Your help will be highly appreciated.

mSelectedmyappOption.setTag("CC");
mSelectedmyappOption.setLabel(app.getResources().getString(R.string.menu_teaching_plan));
mSelectedmyappOption.setPosition(0);
mmyappHorizontalOptionsMenu.setSelectedOption(mSelectedmyappOption, false);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
mTeachingPlanListFragment = new TeachingPlanListFragment();
mTeachingPlanListFragment.intiFragment(schedule);
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_details, mTeachingPlanListFragment)
.commit();
}
},300);
}
}

Finally I have cracked it myself. The problem is I have initialized "View Pager" and "Drawer Menu" from the onResume(). As whenever I come back from other activities "View Pager" and "Drawer Menu" are initialized again which in turn produces StackOverflow exception.

Implement emojis in android keyboard with popupwindow

I've developed a keyboard and now i need to add emojis to it , from other questions i've realized the best way is with popupwindow,
Here's what i've done:
case -102:
LayoutInflater layoutInflater
= (LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.emoji_view, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
popupWindow.showAsDropDown(getWindow().getOwnerActivity().getCurrentFocus(),50, -30);
Unfortunatly this doesn't work , showAsDropDown needs a view as its first var , and if the keyboard is in another app i don't have a view to give him...
Is there a way to fix that ?
or am i going about it all wrong and there is a better way...
all help will be appreciated!

Given that you are using the official SoftKeyBoard implementation as a template for your keyboard:
//Cut some pieces of the code for clarity
case -102:
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.emoji_view, null);
PopupWindow popupWindow = new PopupWindow(popupView, MATCH_PARENT, MATCH_PARENT);
popupWindow.showAsDropDown(mInputView);
Use the view that you have inflated for your keyboard, in the offical SoftKeyBoard and the snippet above it is called mInputView.

hi i have done same things. I have made one custom keyboard in android.

Thanks hope this will help you.It is bit old but you can try it.

you can refer this github link for complete code
EmojiIcon

In windowManager only the last added View can click or do other operators

My code:
public void setAboveButton() {
aboveButton = new TextView(mContext);
ColorDrawable cd = new ColorDrawable(Color.GRAY);
aboveButton.setBackground(cd);
aboveButton.setText("<回游戏");
aboveButton.setGravity(Gravity.CENTER);
aboveButton.setTextSize(25);
aboveButton.setClickable(isClickable());
aboveButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
instance.setVisibility(View.INVISIBLE);
aboveView.setVisibility(View.INVISIBLE);
buttomView.setVisibility(View.INVISIBLE);
aboveButton.setVisibility(View.INVISIBLE);
buttomButton.setVisibility(View.INVISIBLE);
}
});
android.view.WindowManager.LayoutParams viewParams = new android.view.WindowManager.LayoutParams();
viewParams.x = -(dm.widthPixels);
viewParams.y = -(dm.heightPixels);
viewParams.width = dm.widthPixels / 4;
viewParams.height = 120;
instance.mWindowManager.addView(aboveButton, viewParams);
}
public void setBottomButton() {
buttomButton = new TextView(mContext);
ColorDrawable cd = new ColorDrawable(Color.GRAY);
buttomButton.setBackground(cd);
buttomButton.setText("发送");
buttomButton.setGravity(Gravity.CENTER);
buttomButton.setTextSize(25);
buttomButton.setClickable(isClickable());
buttomButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
aboveButton.setVisibility(View.INVISIBLE);
}
});
android.view.WindowManager.LayoutParams viewParams = new android.view.WindowManager.LayoutParams();
viewParams.x = -(dm.widthPixels);
viewParams.y = dm.heightPixels;
viewParams.width = dm.widthPixels / 4;
viewParams.height = 120;
instance.mWindowManager.addView(buttomButton, viewParams);
}
and my MainActivity:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
NoticeBoard.init(MainActivity.this);
NoticeBoard.getInstance().setAboveView();
NoticeBoard.getInstance().setBottomView();
NoticeBoard.getInstance().setBottomButton();
NoticeBoard.getInstance().setAboveButton();
setContentView(NoticeBoard.getInstance());
}
}
Right now, only the last onClick set works. How can I make them work together?
if I change the NoticeBoard.getInstance().setAboveButton() to bottom in the mainActivity,aboveButton's onclick will work,if I change the NoticeBoard.getInstance().setButtomButton() to bottom in mainActivity,bottomButton's onclick will work.
Thanks for your help!

I solve my problem. add flag'WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE' to WindowManager.LayoutParams in every view,and then all view will be worked~

Sliding menu in android,misbehaviour

I am using Sliding menu from library jfeinstein, i have two sliding menu 'menuLeft' 'menuRight' in my activity one from left side and one from right,i have toggle buttons for respective sliding menu,how ever if menuLeft is open and if i slide from right to left in order to close menuLeft ,menuRiht also gets opened,what can be the solution to avoid this misbehaviour
here's my activity which contains SlidingMenu's
public class ChatListActivity extends SherlockActivity {
private SlidingMenu menuLeft;
private SlidingMenu menuRight;
private Button btnSliderLeftToggle;
private Button btnSliderRightToggle;
private ListView lvSliderLeft;
private ListView lvSliderRight;
private int width;

}

I have never faced this issue when i used both Left and Right SlidingMenu but for your problem you can have look at SlidingMenu Issues and you can try this solution for your problem. It may help you.
EDIT :
try this
You will need a patch which calls onOpened and onClosed methods for right menu it may have been included in latest code. Write logs to check method calls.
slidingMenuLeft.setOnOpenedListener(new OnOpenedListener() {
#Override
public void onOpened(int pos) {
slidingMenuRight.setSlidingEnabled(false);
}
});
slidingMenuLeft.setOnClosedListener(new OnClosedListener() {
#Override
public void onClosed() {
slidingMenuRight.setSlidingEnabled(true);
}
});
slidingMenuRight.setOnOpenedListener(new OnOpenedListener() {
#Override
public void onOpened(int pos) {
slidingMenuLeft.setSlidingEnabled(false);
}
});
slidingMenuRight.setOnClosedListener(new OnClosedListener() {
#Override
public void onClosed() {
slidingMenuLeft.setSlidingEnabled(true);
}
});
