• Android沉浸式状态栏背景色以及字体颜色的修改


     在activity中设置透明状态栏 的思路:

           1、让activity的布局全屏 此时布局会和状态栏重叠

           2、让布局最上方预留出和状态栏高度一样的高度,将状态栏的背景色设置为透明

       效果如下:

     

       一般是在setContentView之前设置

    
    
      if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0及以上
                Window window = getWindow();
                window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                        | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
                window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN  //设置为全屏
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        |View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);//状态栏字体颜色设置为黑色这个是Android 6.0才出现的属性   默认是白色
                //需要设置这个 flag 才能调用 setStatusBarColor 来设置状态栏颜色
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                window.setStatusBarColor(Color.TRANSPARENT);//设置为透明色
                window.setNavigationBarColor(Color.TRANSPARENT);
            }else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {//4.4到5.0
                WindowManager.LayoutParams localLayoutParams = getWindow().getAttributes();
                localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags);
            }
             //给标题栏预留出状态栏的高度
            int statusBarHeight = getStatusBarHeight(this);
            mTitleBar.setPadding(0, statusBarHeight, 0, 0);
     /**
         * 获取状态栏高度
         *
         * @param context
         * @return
         */
        private static int getStatusBarHeight(Context context) {
            int result = 0;
            int resourceId = context.getResources().getIdentifier(
                    "status_bar_height", "dimen", "android");
            if (resourceId > 0) {
                result = context.getResources().getDimensionPixelSize(resourceId);
            }
            return result;
        }
