效果图

这里的处理都是Android5.0以上的。

修改状态栏颜色

Window window = activity.getWindow();
window.setStatusBarColor(Color.MAGENTA);

隐藏状态栏

• 法一

Window window = activity.getWindow();
View decorView = window.getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);

• 法二

Window window = activity.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

半透明状态栏

Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

全透明状态栏实现沉浸式

Window window = activity.getWindow();
/*如果之前是办透明模式，要加这一句需要取消半透明的Flag
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);*/
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE |View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);

修改状态栏字体颜色

• 设置状态栏图标和文字颜色为黑色

Window window = activity.getWindow();
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

• 设置状态栏图标和文字颜色为白色

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN|View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
