获取终端输出：结果包裹（00000000'....'）

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button hide=(Button)findViewById(R.id.button1);
        Button show=(Button)findViewById(R.id.button2);
        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();
                    }
            }
        });

                // TODO Auto-generated method stub
                  Log.v("f", "showSystembar");
                    try {
                        Process proc = Runtime.getRuntime().exec(new String[]{

                    } catch (Exception e) {
                        e.printStackTrace();
                    }

推荐答案

进程ID为 SystemUI 类从79改为42 ICS被推出的时候。下面的code适用于任何版本的Andr​​oid您的应用程序可能运行在。

The process id for the SystemUI class changed from 79 to 42 when ICS was introduced.The code below works for any version of Android that your app might be running on.

//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();
}
