[移动开发]Android activity状态栏和导航栏透明

想实现透明页面，包括状态栏和导航栏都透明，点击事件还可以透传。

设置页面透明，使用主题

注册activity设置主题

 <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>

设置状态栏和导航栏透明

直接调用下面方法，传当前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();
                        //两个 flag 要结合使用，表示让应用的主体内容占用系统状态栏的空间
                        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);
                        //导航栏颜色也可以正常设置
                        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();
        }
    }

设置activity点击事件透传

注意要在onCreate方法的setContenView前添加如下代码

//设置activity点击透传
  WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
  layoutParams.flags = WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS |
                    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
           

完美实现。
