    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button hide=(Button)findViewById(R.id.button1);

        hide.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                 Log.v("ds", "hideSystembar");
                    try {
                        Process proc = Runtime.getRuntime().exec(new String[]{
                                "su","-c","service call activity 79 s16 com.android.systemui"});
                        proc.waitFor();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
            }

对于进程id SystemUI类从79变更为42 ICS被引入时。
下面的代码工作为Android的任何版本，您的应用程序可能运行。

//HIDE TOOLBAR
try{
    //REQUIRES ROOT
    Build.VERSION_CODES vc = new Build.VERSION_CODES();
    Build.VERSION vr = new Build.VERSION();
    String ProcID = "79"; //HONEYCOMB AND OLDER

    //v.RELEASE  //4.0.3
    if(vr.SDK_INT >= vc.ICE_CREAM_SANDWICH){
        ProcID = "42"; //ICS AND NEWER
    }

    //REQUIRES ROOT
    Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity "+ ProcID +" s16 com.android.systemui"}); //WAS 79
    proc.waitFor();

}catch(Exception ex){
    Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
}
