Answer 1

You must go to the Android QuickAction widget.

This is an open source GithUb project.

I achieved this behavior using PopUpWindow, here is my code:

// The method that displays the popup.
private void showStatusPopup(final Activity context, Point p) {

   // Inflate the popup_layout.xml
   LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.llStatusChangePopup);
   LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   View layout = layoutInflater.inflate(R.layout.status_popup_layout, null);

   // Creating the PopupWindow
   changeStatusPopUp = new PopupWindow(context);
   changeStatusPopUp.setContentView(layout);
   changeStatusPopUp.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
   changeStatusPopUp.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
   changeStatusPopUp.setFocusable(true);

   // Some offset to align the popup a bit to the left, and a bit down, relative to button position.
   int OFFSET_X = -20;
   int OFFSET_Y = 50;

   //Clear the default translucent background
   changeStatusPopUp.setBackgroundDrawable(new BitmapDrawable());

   // Displaying the popup at the specified location, + offsets.
   changeStatusPopUp.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
}

and this is the layout of PopUp:

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="wrap_content"

    android:text="@string/complete"/>

<ImageView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/devider_popup_task_status_change" 
    android:contentDescription="@drawable/devider_popup_task_status_change"/>

<TextView
    android:id="@+id/tvFailed"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="10dp"
    android:layout_weight="1.0"

    android:layout_marginRight="4dp"
    android:layout_marginBottom="11dp"
    android:text="@string/failed"
    android:textColor="@color/my_black" />
