在我的布局中,我有一个FrameLayout
,我打算根据用户输入显示不同的布局。我想在所有这些布局中显示FloatingActionButton
。
为了不在所有这些中重复FloatingActionButton
,我希望将其附加到FrameLayout
。问题是该按钮未在fragment
布局的顶部正确显示。例如,显示的初始fragment
有GridView
,后面有按钮。
activity_main.xml
:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="xeniasis.mymarket.MainActivity">
<include
android:id="@+id/toolbar"
layout="@layout/toolbar" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:orientation="horizontal"
android:weightSum="4">
<LinearLayout
android:id="@+id/categories_layout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingRight="20dp">
<ExpandableListView
android:id="@+id/categories_listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<FrameLayout
android:id="@+id/mainPane"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3">
<android.support.design.widget.FloatingActionButton
android:id="@+id/settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|start"
android:layout_margin="8dp"
android:clickable="true"
android:elevation="5dp"
android:src="@android:drawable/ic_menu_search" />
</FrameLayout>
</LinearLayout>
</LinearLayout>
并以编程方式显示fragment
布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="xeniasis.mymarket.MainActivity">
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipeRefreshContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:paddingTop="@dimen/activity_vertical_margin">
<GridView
android:id="@+id/productsGridview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:numColumns="3"></GridView>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>

在FrameLayout
中,声明另一个Framelayout
并在那里对片段进行充气。它应该工作。
... <LinearLayout>
.....
<FrameLayout
android:id="@+id/mainPane"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3">
<FrameLayout
android:id="@+id/fragment_inflate"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.FloatingActionButton
android:id="@+id/settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|start"
android:layout_margin="8dp"
android:clickable="true"
android:elevation="5dp"
android:src="@android:drawable/ic_menu_search" />
</FrameLayout>

像这样更改,以便FAB和片段不共享相同的FrameLayout:

在framelayout中添加FAB而不使用coordinativelayout
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/framelayout"
android:layout_below="@+id/drawer_toolbar"
android:layout_above="@+id/drawer_foot" >
<android.support.design.widget.FloatingActionButton
android:id="@+id/shareFab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="8dp"
android:clickable="true"
android:elevation="5dp"
android:src="@android:drawable/ic_menu_share" />
</FrameLayout>

找到框架布局并调用此方法,然后以100%的方法传递框架布局
private void addFloatingButton(FrameLayout frameLayout) {
int i20 = 20;
int i50 = 50;
FrameLayout.LayoutParams clFloatingButtonParams = new FrameLayout.LayoutParams(i50, i50);
clFloatingButtonParams.setMargins(0, 0, i20, i20);
clFloatingButtonParams.gravity = Gravity.BOTTOM | Gravity.END;
FloatingActionButton clFloatingActionButton = new FloatingActionButton(getActivity());
clFloatingActionButton.setId(R.id.calander_view_fab);
frameLayout.addView(clFloatingActionButton, clFloatingButtonParams);
}
