/** Play popwindow **/TV = (TextView) findViewById (R. id. textView1); view_pop = LayoutInflater. from (MainActivity. this ). inflate (R. layout. pop_menu, null); TV. setOnClickListener (new OnClickListener () {@ Overridepublic void onClick (View arg0) {if (mPopupwinow = null) {// create a new listener = new PopupWindow (view_pop, LayoutParams. WRAP_CONTENT, LayoutParams. WRAP_CONTENT, true); // set the background color of the popwindow to mPopupwinow. setBackgroundDrawable (new ColorDrawable (0x00000000);} // set the position of popwindow to TV: + view in the upper right corner and mPopupwinow below +. showAsDropDown (TV, 0, 0 );}});

TV _cancle); TV _cancle.setOnClickListener (new OnClickListener () {@ Overridepublic void onClick (View arg0) {dialog. dismiss () ;}});/** get the window object and parameter object of the Christmas box to modify the layout settings of the dialog box. You can directly call getWindow (), the Window * object of the Activity, which can be changed in the same way. */Window dialogWindow = dialog. getWindow (); // set the location dialogWindow. setGravity (Gravity. BOTTOM); // set the dialogWindow attribute of the width and height of the dialog. setLayout (LayoutParams. MATCH_PARENT, LayoutParams. WRAP_CONTENT); dialog. show ();}
