	      mSpinnerAdapter = new ArrayAdapter(getActivity(), R.layout.spinner_layout);
	      mSpinnerAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
	      
	      if(null != mTargetArray) {
	          for(Target target: mTargetArray) {
	              mSpinnerAdapter.add(target.getDisplayname());         
	          }
	 
	          mSpinner.setOnItemSelectedListener(new MeasurementTargetOnItemSelectedListener());
	      } else {
	          mSpinnerAdapter.add("没有可供选择的服务器");      
	      }
	      
	      mSpinner.requestFocus();       
	      mSpinner.setAdapter(mSpinnerAdapter);
