The

 popupwindow is one of our frequent customers, and it is easy to use.
  wrote the simplest custom Popupwindow, recorded, easy to use later on the above changes can be.

/** * @param * @author LDM * @description Custom Popupwindow * @time 2016/9/29 15:26 * * public class Custompopup extends
  Popupwindow {//contextual private context mcontext;
  Popupwindow Control Click event Callback interface private Ipopuwindowlistener Monclicklistener;
   Popupwindow the button Private button alarm_pop_btn in the layout file; /** * @description Construction method * @author LDM * @time 2016/9/30 9:14 * @param/Public custompopup (Context Mcont

    This.mcontext = Mcontext;
    This.monclicklistener = listener;
    Get layout file View Mcontentview = Layoutinflater.from (Mcontext). Inflate (R.layout.alarm_disopse_pop, NULL);
    Set Layout Setcontentview (Mcontentview);
    Set the width of the window and height setwidth (width);
    SetHeight (height);
    Sets whether to get focus setfocusable (FALSE);
    Set Popupwindow to enter and exit animation effect Setanimationstyle (R.style.popwindow_exit_anim_style); Settouchable (TRUE); The default is true, set to False, all touch events are not responding, and are PopupwindowThe covered Activity section responds to clicks//sets the window clickable, clicking Popupwindow outside the range, Popupwindow will not disappear setoutsidetouchable (false); External can be clicked, set drawable reason can refer to: http://blog.csdn.net/harvic880925/article/details/49278705 setbackgrounddrawable (
    New Bitmapdrawable ());
  Setting the layout interface of the Initui (); /** * Initialization Window list */private void Initui () {//get to button alarm_pop_btn = (button) Getcontentview (). Findviewbyid
    (R.ID.ALARM_POP_BTN); Set button click event Alarm_pop_btn.setonclicklistener (New View.onclicklistener () {@Override public void OnClick (Vie
        W view) {if (null!= monclicklistener) {monclicklistener.dispose ();
  }
      }
    });
    }/** * Display the Window list interface */public void Show (view view) {int[] location = new INT[2];
    View.getlocationonscreen (location);
  Gravity.bottom is set under View, and can be set according to location to POPUPWINDOWJ display position showatlocation (view, gravity.bottom, 0, 0); /** * @param * @author LDM * @description Click event Callback Processing interface * @time 2016/7/29 15: */public interface Ipopuwindowlistener {void Dispose ();

 }
}

Note: Setting the width of the Popupwindow can also be set by Layoutparams, for example:

 Set the height and width of the Popupwindow by Layoutparams
  viewgroup.layoutparams LP = (viewgroup.layoutparams) Mcontentview.getlayoutparams ();
   lp.widht=400;
   Lp.height = 180;
  MCONTENTVIEW.SETLAYOUTPARAMS (LP);
  But the LP that you get directly to this is probably empty, and when we get the layoutparams of a view, it's usually written like this:
  //Addongloballayoutlistener to get view Layoutparams  mcontentview.getviewtreeobserver (). Addongloballayoutlistener (New Viewtreeobserver.ongloballayoutlistener () {
      @Override public
      void Ongloballayout () {
        viewgroup.layoutparams LP = (viewgroup.layoutparams) Mcontentview.getlayoutparams ();
        Lp.height = 180;
        Lp.width = n;
        MCONTENTVIEW.SETLAYOUTPARAMS (LP);
      }
    );

Used in activity:

Private Custompopup Alarmpopup;
....
Initialize Popupwindow here the Popupwindow height
alarmpopup=new custompopup (getactivity () is set through the data 200来. ViewGroup.LayoutParams.MATCH_PARENT, this); Here this means that the current activity implements the Popupwindow Ipopuwindowlistener interface
// Pop-up Popupwindow
 @Override
  protected void Widgetclick (View v) {
    Super.widgetclick (v);
    Switch (V.getid ()) {case
      r.id.popup:
        alarmpopup.show (v);
        break;
    }
  }
  Process Popupwindow button Click Callback
   @Override public
  void Dispose () {
    //todo sth 
    if (alarmpopup.isshowing ()) {
        Alarmpopup.dismiss ()//close Popupwindow
      }
  }

Popupwindow the corresponding layout interface:

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
  android:id=" @+id/pop_ll "
