使用:
在App設置主題爲notitle
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:windowActionBar">false</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
然後在Activity的佈局文件中設置背景顏色,或者背景圖片
在java文件中調用
StatusBarUtil.setTransparent(this);
即可設置成功;
同時可以設置狀態欄爲其他顏色
StatusBarUtil.setColorNoTranslucent(this, Color.parseColor("#39b3f4"));
