试试这个
View aView = getWindow().getDecorView();
aView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
但我建议您先阅读Link

在您的活动中尝试以下代码:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

你可以使用它
@Override
@SuppressLint(" NewApi&#34) protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
currentApiVersion = android.os.Build.VERSION.SDK_INT;
final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
// This work only for android 4.4+
if(currentApiVersion >= Build.VERSION_CODES.KITKAT)
{
getWindow().getDecorView().setSystemUiVisibility(flags);
// Code below is to handle presses of Volume up or Volume down.
// Without this, after pressing volume buttons, the navigation bar will
// show up and won't hide
final View decorView = getWindow().getDecorView();
decorView
.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener()
{
@Override
public void onSystemUiVisibilityChange(int visibility)
{
if((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0)
{
decorView.setSystemUiVisibility(flags);
}
}
});
}
@SuppressLint("NewApi")
@Override
public void onWindowFocusChanged(boolean hasFocus)
{
super.onWindowFocusChanged(hasFocus);
if(currentApiVersion >= Build.VERSION_CODES.KITKAT && hasFocus)
{
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
