可折叠工具栏-使片段页脚在Android中始终可见 [英] Collapsible Toolbar - Make Fragment Footer Always Visible in Android
本文介绍了可折叠工具栏-使片段页脚在Android中始终可见的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在制作一个包含三个片段的ProfilePage的应用-关于|帖子|画廊，我正在使用带有用户图像的可折叠工具栏.我的第二个和第三个片段的页脚应该始终可见，但这就是我得到的:
I am making an app that has a ProfilePage with three fragments - About | Posts | Gallery, and I am using a collapsible toolbar with user's image. My second and third fragment will have a footer that should always be visible, but this is what I get:
当我的图像展开时，页脚消失.我想要的是让我的两个片段始终具有这些页脚，而不取决于折叠或不折叠的工具栏.我的画廊页脚应类似于发布页脚.
When my image is expanded the footer disappears. What I want is for my two fragments to have these footers always visible and not depending on toolbar being collapsed or not. My gallery footer should be similar to post footer.

return view;

推荐答案
我对其中一个应用程序有相同的要求.我只是做了解决方法.
在标签版式中添加所需的版式:
I had the same requirement for my one of apps. I just did workaround.
Add your required layout in tab layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="256dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
contentScrim="?attr/colorPrimary"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="@+id/profile_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:contentDescription="@string/profile_photo"
app:layout_collapseMode="none"/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin">
<ImageView
android:id="@+id/toolbarEdit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:contentDescription="@string/block"
android:paddingEnd="20dp"
android:paddingStart="5dp"
app:srcCompat="@drawable/ic_icon_edit" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.design.widget.TabLayout
android:id="@+id/myProfileTabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:tabContentStart="72dp"
app:tabGravity="fill"
app:tabMode="scrollable" />
<android.support.v4.view.ViewPager
android:id="@+id/myProfileViewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</LinearLayout>
<-- Your required layout -->
<LinearLayout
android:id="@+id/tab123"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:gravity="bottom"
android:orientation="horizontal"
android:visibility="gone"
android:weightSum="4">
<EditText
android:id="@+id/inputMsg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="3"
android:paddingLeft="6dp"
android:paddingRight="6dp" />
<Button
android:id="@+id/btnSend"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="send" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
在标签"活动中添加以下代码:
Add following code in your Tab activity:
TabLayout tabLayout;
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);//add your viewpager to TabLayout
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
LinearLayout l=(LinearLayout) findViewById(R.id.tab123);
final EditText text=(EditText) findViewById(R.id.inputMsg);
Button send=(Button) findViewById(R.id.btnSend);
if (tab.getPosition() == 0) {
l.setVisibility(View.GONE);
System.out.println("About tab");
} else if (tab.getPosition() == 1) {
l.setVisibility(View.VISIBLE);
System.out.println("Posts tab");
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input
// Perform your desired task.
}
});
} else if (tab.getPosition() == 2) {
l.setVisibility(View.VISIBLE);
System.out.println("Gallery tab");
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String msg = null;
msg = text.getText().toString(); //get input
//Perform your desired task.
}
});
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
