Question

底部导航隐藏在设备按钮的后面，请参见下图：

我不能使用任何scrollview视图或任何其他视图。

请参阅以下我的活动代码：

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"

分隔您的布局

content_layout.xml

<RelativeLayout 
 xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_below="@+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
    android:id="@+id/nav_Frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:layout_above="@+id/bottom_navigation"
    >
</FrameLayout>

<LinearLayout
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="@dimen/_40sdp"
    android:background="@color/white"
    android:layout_alignParentBottom="true"
    >

    <ImageView
        android:id="@+id/iv_home"
        android:layout_width="@dimen/_20sdp"
        android:layout_height="@dimen/_20sdp"
        android:src="@drawable/ic_myaccount"
        android:tint="@color/light_gray"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        />

    <ImageView
        android:id="@+id/iv_notification"
        android:layout_width="@dimen/_20sdp"
        android:layout_height="@dimen/_20sdp"
        android:src="@drawable/ic_myaccount"
        android:tint="@color/light_gray"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        />

    <ImageView
        android:id="@+id/iv_add"
        android:layout_width="@dimen/_20sdp"
        android:layout_height="@dimen/_20sdp"
        android:src="@drawable/ic_myaccount"
        android:tint="@color/light_gray"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        />

    <ImageView
        android:id="@+id/iv_massage"
        android:layout_width="@dimen/_20sdp"
        android:layout_height="@dimen/_20sdp"
        android:src="@drawable/ic_myaccount"
        android:tint="@color/light_gray"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        />

    <ImageView
        android:id="@+id/iv_account"
        android:layout_width="@dimen/_20sdp"
        android:layout_height="@dimen/_20sdp"
        android:src="@drawable/ic_myaccount"
        android:tint="@color/light_gray"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        />

</LinearLayout>

drawer_activity.xml

<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:openDrawer="start"
android:background="#E2DEDE"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="start"

Answer 2

尝试一下

将此添加到您的应用主题中：

<item name="android:windowTranslucentNavigation">false</item>

Answer 3

从扩展您的底部导航

public class BottomNavigationBehavior extends CoordinatorLayout.Behavior<BottomNavigationView> {

public BottomNavigationBehavior() {
    super();
}

public BottomNavigationBehavior(Context context, AttributeSet attrs) {
    super(context, attrs);
}
@Override
public boolean layoutDependsOn(CoordinatorLayout parent, BottomNavigationView child, View dependency) {
    boolean dependsOn = dependency instanceof FrameLayout;
    return dependsOn;
}
@Override
public boolean onStartNestedScroll(CoordinatorLayout coordinatorLayout, BottomNavigationView child, View directTargetChild, View target, int nestedScrollAxes) {
    return nestedScrollAxes == ViewCompat.SCROLL_AXIS_VERTICAL;
}

@Override
public void onNestedPreScroll(CoordinatorLayout coordinatorLayout, BottomNavigationView child, View target, int dx, int dy, int[] consumed) {
    if (dy < 0) {
        showBottomNavigationView(child);
    } else if (dy > 0) {
        hideBottomNavigationView(child);
    }
}

private void hideBottomNavigationView(BottomNavigationView view) {
    view.animate().translationY(view.getHeight());
}

private void showBottomNavigationView(BottomNavigationView view) {
    view.animate().translationY(0);
}

}

Answer 4

我对此进行了搜索，最后我明白了为什么该底部导航显示在底部栏下

我在Java类中的Flag下方删除。

getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

我添加了此标志以将Actionbar和Statusbar混合使用。

因此，我只删除了该标志，它看起来很完美。：）

Answer 5

尝试一下

将此添加到您的活动xml中：根DrawerLayout：

    android:fitsSystemWindows="true"

Answer 6

要在任何活动中实现这一目标

添加样式：

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/white</item>
</style>

将CoordinatorLayout用作活动的XML的根布局
在oncreate()方法中，在使用setcontentview之前

window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE或 View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

底部栏跌至导航栏后面的低处
