直播app原始碼，狀態列和導航欄設定成透明狀態實現的相關程式碼

設定頁面透明，使用主題

註冊activity設定主題

<style name="TranslucentNoActionBarTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowContentTransitions">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsTranslucent">true</item>
  </style>

設定狀態列和導航欄透明

直接呼叫下面方法，傳當前activity即可

public void setNavAndStatusBarTransparent(Activity activity) {
    if (activity == null) {
      return;
    }
    try {
      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window window = activity.getWindow();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
          if (window != null) {
            View decorView = window.getDecorView();
            //兩個 flag 要結合使用，表示讓應用的主體內容佔用系統狀態列的空間
            int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
            decorView.setSystemUiVisibility(option);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.TRANSPARENT);
            //導航欄顏色也可以正常設定
            window.setNavigationBarColor(Color.TRANSPARENT);
          }
        } else {
          if (window != null) {
            WindowManager.LayoutParams attributes = window.getAttributes();
            if (attributes != null) {
              int flagTranslucentStatus = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
              int flagTranslucentNavigation = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
              attributes.flags |= flagTranslucentStatus;
              attributes.flags |= flagTranslucentNavigation;
              window.setAttributes(attributes);
            }
          }
        }
      }
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

設定activity點選事件透傳

注意要在onCreate方法的setContenView前新增如下程式碼

//設定activity點選透傳
 WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
 layoutParams.flags = WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS |
          WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
