   Builder dialog  =   new  AlertDialog.Builder( this );
   LayoutInflater inflater  =  (LayoutInflater)  this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   LinearLayout layout  =  (LinearLayout)inflater.inflate(R.layout.dialogview,  null );
   dialog.setView(layout);
   et_search  =  (EditText)layout.findViewById(R.id.searchC);
   dialog.setPositiveButton( " 查找 " ,  new  DialogInterface.OnClickListener() {
     public   void  onClick(DialogInterface dialog,  int  which) {
     String searchC  =  et_search.getText().toString();
     Intent intent  =   new  Intent();
     Bundle bundle  =   new  Bundle();
     bundle.putString( " search " , searchC);
     intent.putExtras(bundle);
     intent.setClass(ViewResultActivity. this , SearchResult. class );
     ViewResultActivity. this .startActivity(intent);
    }
