沉浸式体验
4.4以上的系统支持实现隐藏状态栏,导航栏实现沉浸式的效果。
单独隐藏状态栏必须在setContextView后调用
int option = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(option);
View.SYSTEM_UI_FLAG_FULLSCREEN, //全屏,状态栏和导航栏不显示
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION, //隐藏导航栏
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN, //全屏,状态栏会盖在布局上
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION,
View.SYSTEM_UI_FLAG_LAYOUT_STABLE,
View.SYSTEM_UI_FLAG_LOW_PROFILE,
View.SYSTEM_UI_FLAG_VISIBLE, //显示状态栏和导航栏
View.SYSTEM_UI_LAYOUT_FLAGS
隐藏状态栏和导航栏
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
View decorView = getWindow().getDecorView();
int option = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
自定义 StatusBarColor
android 4.4以上的系统支持自定义statusBar的颜色也就是我们的状态栏颜色。主要是通过获取activity的 window.setStatusBarColor(color)来设置。使用的时候需要判断版本号4.4以上的系统才能这样做。
