我有一个
Android Jelly Bean平板电脑已经扎根并且试图运行一个应用程序,其中包含隐藏系统栏的代码,但它没有被隐藏,任何人都可以帮助我解决这个问题.
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();
}
}
});
show.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.v("f","showSystembar");
try {
Process proc = Runtime.getRuntime().exec(new String[]{
"am","startservice","-n","com.android.systemUI/.systemUIService"});
proc.waitFor();
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}
虽然我正在获得许可的祝酒：

解决方法
当引入ICS时,systemUI类的进程ID从79更改为42.下面的代码适用于您的应用可能正在运行的任何Android版本.
//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","service call activity "+ ProcID +" s16 com.android.systemUI"}); //WAS 79
proc.waitFor();
}catch(Exception ex){
Toast.makeText(getApplicationContext(),ex.getMessage(),Toast.LENGTH_LONG).show();
}
