Close Spinner On Click Outside Of Spinner

I want to close an Android spinner once I click outside of the Spinner. Is that even possible?

Solution 1:

I've had some luck with this, even if it doesn't completely work.

The spinner adapter's get view :

public View getView(int position, View v, ViewGroup parent) {
   if (v == null) {
      LayoutInflatermLayoutInflater= mActivity.getLayoutInflater();
      v = mLayoutInflater.inflate(R.layout.user_row, null);
   }

   ViewtempParent= (View) parent.getParent().getParent().getParent();
   tempParent.setOnTouchListener(newMyOnTouchListener(mActivity));
   mActivity.setOpen(true);

   UsergetUser= mUsers.get(position);
   return v;
}

The ontouch listener :

publicclassMyOnTouchListenerimplementsOnTouchListener{
   private MyActivity mOverall;
   publicMyTouchListener(MyActivity overall) {
      mOverall = overall;
   }

   publicbooleanonTouch(View v, MotionEvent event) {
      if (mOverall.getOpen()) {
         mOverall.getWindow().setContentView(R.layout.main); //reset your activity             screen
         mOverall.initMainLayout(); //reset any code.  most likely what's in your oncreate
      }
      returnfalse;
   }  
}

The on item selected listener :

publicclassMySelectedListenerimplementsOnItemSelectedListener {
   publicvoidonItemSelected(AdapterView<?> parent, View view, int pos,
    long id) {
     setUser(pos); //or whatever you want to do when the item is selected
     setOpen(false);         
  }
  publicvoidonNothingSelected(AdapterView<?> parent) {}
}

The activity

Your activity with the spinner should have a global variable mOpen with get and set methods. This is because the ontouch listener tends to stay on even after the list is closed.

The limitations of this method:

It closes if you touch between the spinner and the options or to the side of the options. Touching above the spinner and below the options still won't close it.

Solution 2:

Try

@OverridepublicvoidonFocusChange(View v, boolean hasFocus) {

if (!hasFocus) v.setVisibility(View.GONE);

}

Solution 3:

I wanted to be able to determine when the spinner menu was displayed, and dismissed as well. After a lot of searching, there wasn't a lot of good solutions. I was able to accomplish this by doing the following:

1. Created a custom spinner class, and override the following method:

   @OverridepublicbooleanperformClick() {
   this.isDropDownMenuShown = true; //Flag to indicate the spinner menu is shownreturnsuper.performClick();
   }
   

2. In my Activity, override the method onWindowFocusChanged(boolean hasFocus). If hasFocus == true && the flag in #1 is set to true, then the spinner has been dismissed (can be either by selection or tapping outside the spinner).

   @OverridepublicvoidonWindowFocusChanged(boolean hasFocus) {
   super.onWindowFocusChanged(hasFocus);
   if (actionBarSpinner.isDropdownShown() && hasFocus) {
       actionBarSpinner.setDropdownShown(false);
       //Do you work here
   }
   

   }

Good luck!
