Service中:
` 
public class MyJobService extends JobService {
        public static TextView myView;
        @Override
        public boolean onStartJob(JobParameters params) {
                myView = new TextView(this);
                myView.setText("在Service中新建");
                myView.setTextColor(Color.parseColor("#000000"));
                return false;
        }
        @Override
        public boolean onStopJob(JobParameters params) {
                return false;
        }}
`
Activity的onCreate中:
`
    myView = MyJobService.myView;
                    if (myView != null) {
                            ((RelativeLayout)findViewById(R.id.activity_main)).addView(myView);
                    }`
最终的验证结果是可以正常显示的。
