关于android 沉浸式状态栏

public class BaseActivity extends Activity{
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 // TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
 //setNaviHide(this);
 }
    //完全透明的实现方法，在 onCreate()中调用即可
@SuppressLint("NewApi") 
private void setNaviHide(Activity activity){
    if(VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window window = activity.getWindow();
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(Color.TRANSPARENT);
        window.setNavigationBarColor(Color.TRANSPARENT);
    }

    //去掉状态栏


// getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,WindowManager.LayoutParams. FLAG_FULLSCREEN);
 }
 }
