Android Immersive Mode (沉浸模式) 还是 Translucent Bars (透明状态栏)
Immersive Mode (沉浸模式) 还是 Translucent Bars (透明状态栏)
为什么在国内会有很多用户把「透明栏」(Translucent Bars)称作 「沉浸式顶栏」?
完全隐藏 System Bars 的 Immersive Mode, 在大部分时候 Translucent Bars 并不能营造沉浸式体验
当Android系统版本大于19(4.4),就可以开启透明标题栏:
可以将其封装成方法进行调用。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window win = getWindow(); WindowManager.LayoutParams winParams = win.getAttributes();
winParams.flags |= WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
win.setAttributes(winParams); SystemBarTintManager tintManager = new SystemBarTintManager(this);
tintManager.setStatusBarTintEnabled(true);
tintManager.setStatusBarTintColor(Color.TRANSPARENT);
}
注意:
1. 单纯图片背景时,要使得视图xml根视图的,背景图全屏时,需要设置isFitsSystemWindows=false。
2.对于有TopBar的,需要设置根视图的paddingTop:
mRootView.setPadding(0, getStatusBarHeight(mContext), 0, 0);
// 通过反射获取状态栏高度
public static int getStatusBarHeight(Context context) {
try {
Class<?> c = Class.forName("com.android.internal.R$dimen");
Object obj = c.newInstance();
Field field = c.getField("status_bar_height");
int x = Integer.parseInt(field.get(obj).toString()); return context.getResources().getDimensionPixelSize(x);
} catch (Exception e) {
e.printStackTrace();
} return 0;
}
// 沉浸式状态栏
