   LayoutInflater inflater = LayoutInflater.from(this); 
   View mInflate = inflater.inflate(R.layout.activity_plus, null); 
   iv_dialog_cacle = (ImageView) mInflate.findViewById(R.id.iv_cancel); 
   iv_dialog_cacle.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     dialog.dismiss();

   WindowManager windowManager = getWindowManager(); 
   Display display = windowManager.getDefaultDisplay(); 
   WindowManager.LayoutParams lp= dialog.getWindow().getAttributes(); 
   lp.width = (int)(display.getWidth()); //设置宽度
