Android 沉浸式状态栏 一体化状态栏实现

jopen 5年前


苹果上的UI基本上都是这个效果,然而Android机上的顶部状态栏总是和app的主题颜色不搭。还好如今的api19以上的版本,我们也能做出这样的效果。




第一步:

// 需要setContentView之前调用          private void setTranslucentStatus() {    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {     // 透明状态栏     getWindow().addFlags(       WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);     // 透明导航栏     getWindow().addFlags(       WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);                          SystemStatusManager tintManager = new SystemStatusManager(this);     tintManager.setStatusBarTintEnabled(true);                          // 设置状态栏的颜色                           tintManager.setStatusBarTintResource(R.color.theme_color);     getWindow().getDecorView().setFitsSystemWindows(true);    }   }
第二步:

为xml 的根布局添加android:fitsSystemWindows="true" 属性

第三步:SystemStatusManager 源码
