状态栏和工具栏重叠

标签: android android-toolbar android-statusbar

看了无数关于如何应用gradient drawable作为Toolbar背景的帖子后,我发现了下面的代码。但是,这会导致两个问题:1)整个活动的背景具有与背景相同的可绘制渐变; 2)如您在布局预览中看到的Toolbarstatus bar重叠。

我猜测可以通过添加另一个布局(例如另一个ConstraintLayout)并将我的偏好颜色用作背景来解决第一个问题,但这会有效吗?

关于第二期,我几乎一无所知。我从未使用过状态栏。这是我正在使用的标志之一吗?我应该以某种方式将整个工具栏限制在状态栏下方吗在它的dp中添加一些top constraint

MainActivity.java,我在setStatusBarGradient()方法之前调用setContentView()

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public static void setStatusBarGradient(Activity activity) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Window window = activity.getWindow();
        Drawable background = activity.getResources().getDrawable(R.drawable.toolbar_gradient);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); // causing the issue
        window.addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        window.setStatusBarColor(activity.getResources().getColor(android.R.color.transparent));
        window.setNavigationBarColor(activity.getResources().getColor(android.R.color.transparent));
        window.setBackgroundDrawable(background);
    }
}

而我的AppTheme风格有这两行:

    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>

我尝试过使用android:fitsSystemWindows="true",但那里没有运气。
