我有一个基本活动,其中包含来自android studio中示例的drawer navigation
。我让statusbar
透明了,我希望菜单在它下滑动,允许它的颜色溢出到透明度中,如下所示:
(注意右边的蓝色)
但默认情况下,它看起来像这样:
蓝色来自主题colorPrimaryDark,但我想动态改变这种颜色,所以我不能依赖主题。有没有办法动态/编程设置颜色?
getWindow().getDecorView().setBackgroundColor(Color.White)
设置状态栏的颜色并使用标志
DRAWS_SYSTEM_BAR_BACKGROUNDS
:
if(android.os.Build.VERSION.SDK_INT> = Build.VERSION_CODES.LOLLIPOP){ window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); window.setStatusBarColor(Color.BLUE); }
(对不起编码块不好,它不想听)
这不会使其透明为第一张图片,而只是纯色。
anyView.getRootView().setBackgroundColor()

在Activity
:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
String dynamicColor = "#99000000";
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); /*You were missing this*/
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.parseColor(dynamicColor));
}
