我搜索了文档,但只找到了这个:
链接。这是用来使酒吧半透明?我想做的是使状态栏完全透明(如下图所示),并使它向后兼容APK<19:
我的styles.xml:
<resources xmlns:tools="http://schemas.android.com/tools">
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:actionBarStyle">@style/ThemeActionBar</item>
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="actionBarStyle">@style/ThemeActionBar</item>
<item name="windowActionBarOverlay">true</item>
</style>
<style name="ThemeActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid">
<item name="android:background"> @null </item>
<!-- Support library compatibility -->
<item name="background">@null</item>
<item name="android:displayOptions"> showHome | useLogo</item>
<item name="displayOptions">showHome|useLogo</item>
</style>
</resources>
我能做的是:
适用于Android KitKat和以上(对于那些想要透明的状态栏和不操作导航栏,因为所有这些答案将透明导航栏太!)
最简单的实现方法:
把这3行代码放在styles.xml (v19) ->中,如果你不知道如何有这个(v19),只需要把它们写在默认的styles.xml中,然后使用alt+enter自动创建它:
<item name="android:windowFullscreen">false</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:fitsSystemWindows">false</item>
现在,转到MainActivity类,把这个方法从类的onCreate中放出来:
public static void setWindowFlag(Activity activity, final int bits, boolean on) {
Window win = activity.getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
然后把这段代码放到Activity的onCreate方法中:
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
//make fully Android Transparent Status bar
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
就是这样!
