Question

这是我的问题：我需要折叠包含一些textfield，button和LinearLayout的所有协调布局;但是当我实现我的代码（下面的代码）时，崩溃不会像我期望的那样。我希望在not collapsed layout上显示所有布局，当用户向下滚动时，折叠工具栏布局应显示一个布局：＆＃34; partenza：...，arrivo：...＆＃34;代替标题。

有什么想法吗？

是的，这是可能的！对于简单的可折叠布局，您可以执行以下操作：

final TextView descriptionText = (TextView) view.findViewById(R.id.detail_description_content);
        final TextView showAll = (TextView) view.findViewById(R.id.detail_read_all);
        showAll.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                showAll.setVisibility(View.INVISIBLE);

                descriptionText.setMaxLines(Integer.MAX_VALUE);
            }
        });

XML：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:id="@+id/detail_description_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <TextView
            android:id="@+id/detail_description_content"
            android:maxLines="5"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
        <TextView
            android:id="@+id/detail_read_all"
            android:clickable="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    </LinearLayout>
</ScrollView>
