Question

ViewPager叠加在fab之上。如何将晶圆厂放在首位？

的xml：

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:clickable="true"
    android:src="@drawable/ic_add"
    android:visibility="visible" />

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:contextClickable="true">

    <android.support.design.widget.TabLayout
        android:id="@+id/personal_tasks_tabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabSelectedTextColor="#deFFFFFF"
        app:tabTextColor="#81ffffff"
        app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/personal_tasks_viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

或许这不是原因？只是没有按下按钮，但当我在上面时，标签会翻过来。

Answer 1

// Create Variable list var variables = new List<Variable> { new Variable { Label = "The variable Label", ValueLabels = new Dictionary<double, string> { {1, "Label for 1"}, {2, "Label for 2"}, }, Name = "avariablename_01", PrintFormat = new OutputFormat(FormatType.F, 8, 2), WriteFormat = new OutputFormat(FormatType.F, 8, 2), Type = DataType.Numeric, Width = 10, MissingValueType = MissingValueType.NoMissingValues }, new Variable { Label = "Another variable", ValueLabels = new Dictionary<double, string> { {1, "this is 1"}, {2, "this is 2"}, }, Name = "avariablename_02", PrintFormat = new OutputFormat(FormatType.F, 8, 2), WriteFormat = new OutputFormat(FormatType.F, 8, 2), Type = DataType.Numeric, Width = 10, MissingValueType = MissingValueType.OneDiscreteMissingValue } }; // Set the one special missing value variables[1].MissingValues[0] = 999; // Default options var options = new SpssOptions(); using (FileStream fileStream = new FileStream("data.sav", FileMode.Create, FileAccess.Write)) { using (var writer = new SpssWriter(fileStream, variables, options)) { // Create and write records var newRecord = writer.CreateRecord(); newRecord[0] = 15d; newRecord[1] = 15.5d; writer.WriteRecord(newRecord); newRecord = writer.CreateRecord(); newRecord[0] = null; newRecord[1] = 200d; writer.WriteRecord(newRecord); writer.EndFile(); } }就像一个超级CoordinatorLayout，所以如果您在顶部放置FrameLayout，然后添加FAB，ViewPager将覆盖ViewPager /叠加上一个视图。你可以尝试将你的FAB移到底部。

<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:contextClickable="true">

<android.support.design.widget.TabLayout
    android:id="@+id/personal_tasks_tabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabSelectedTextColor="#deFFFFFF"
    app:tabTextColor="#81ffffff"
    app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/personal_tasks_viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:clickable="true"
    android:src="@drawable/ic_add"
    android:visibility="visible" />

</android.support.design.widget.CoordinatorLayout>

您还可以尝试将FAB锚定到ViewPager

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    app:layout_anchor="@id/personal_tasks_viewpager"
    app:layout_anchorGravity="bottom|end"
</android.support.design.widget.CoordinatorLayout>

浮动操作按钮和查看寻呼机
