Android顶部状态栏透明化并释放空间的两种实现方法

if(Build.VERSION.SDK_INT >=19){

  WindowManager.LayoutParams localLayoutParams = mActivity.getWindow().getAttributes();

  localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags);

  if(fmMain !=null) { //fmMain：自定义的顶部导航条

   LinearLayout.LayoutParams  layoutParams = (LinearLayout.LayoutParams) fmMain.getLayoutParams();

   layoutParams.setMargins(0, ChuangChuangApp.STATUSBARHEIGHT,0,0);//STATUSBARHEIGHT状态栏高度

  fmMain.setLayoutParams(layoutParams); //设置顶部margin值

  }

 }

if(Build.VERSION.SDK_INT >=21) {

  View decorView = getWindow().getDecorView();

  fmMain.setBackgroundColor(Color.TRANSPARENT);

  intoption = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

   | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;

  decorView.setSystemUiVisibility(option);

  getWindow().setStatusBarColor(Color.TRANSPARENT);
