getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {  @Override  public void onSystemUiVisibilityChange(int visibility) {    int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |        //布局位于状态栏下方        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |        //全屏        View.SYSTEM_UI_FLAG_FULLSCREEN |        //隐藏导航栏        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;    if (Build.VERSION.SDK_INT >= 19) {      uiOptions |= 0x00001000;    } else {      uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;    }    getWindow().getDecorView().setSystemUiVisibility(uiOptions);  }});

mDialog.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);mDialog.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {  @Override  public void onSystemUiVisibilityChange(int visibility) {    int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |        //布局位于状态栏下方        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |        //全屏        View.SYSTEM_UI_FLAG_FULLSCREEN |        //隐藏导航栏        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;    if (Build.VERSION.SDK_INT >= 19) {      uiOptions |= 0x00001000;    } else {      uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;    }    mDialog.getWindow().getDecorView().setSystemUiVisibility(uiOptions);  }});要在mDialog.show();之前。
