在android列表视图中有可能吗?

做一件事。将一个文本视图放在列表视图的正上方,并将文本设置为标题。这将满足您的需要。

您可以在列表视图中添加标题,如下所示:

View headerView = ((LayoutInflater)Activity.this.getSystemService(Activity.this.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.header, null, false);
list.addHeaderView(headerView)
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <include layout="@layout/header" />

   <ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</TableLayout>

对我来说,有效的解决方案是创建一个TableLayout,它有一行标题和一行列表,如下所示:

View headerView = ((LayoutInflater)Activity.this.getSystemService(Activity.this.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.header, null, false);
list.addHeaderView(headerView)
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <include layout="@layout/header" />

   <ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</TableLayout>


请确保ListView的id为@android:id/list。

是的,以下是我所做的:

对于带有
ListActivity
ListFragment
的自定义版面,版面必须包含
ListView
,且
android:id
属性设置为
@android:id/list

1)
main_layout.xml

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    // custom Headers
    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/systolic" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/diastolic" />

        <TextView
            android:id="@+id/textView3"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/date" />
    </LinearLayout>

    // This is important to be exactly like below ,android:id="@android:id/list"

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/linearLayout1" >
    </ListView>

</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/bpSysHolder"
        android:layout_width="fill_parent"

        android:gravity="center"
        android:layout_gravity="center_vertical"
        android:text="TextView" >
    </TextView>

</LinearLayout>

3)
ListActivity

public class HistoryActivity extends ListActivity {
        private SimpleCursorAdapter dbAdapter;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            // this is neccessery for you
            setContentView(R.layout.main_layout);

            dao = new BpDAO(this);

            Cursor bpList = dao.fetchAll_bp();

            String[] from = new String[] { BpDAO.bp_SYS, BpDAO.bp_DIA, BpDAO.bp_DT };
            int[] target = new int[] { R.id.bpSysHolder, R.id.bpDiaHolder,
                    R.id.bpDtHolder };

            // And this for custom row layout for each list row
            dbAdapter = new SimpleCursorAdapter(this, R.layout.custom_list_row,
                    bpList, from, target);

            setListAdapter(dbAdapter);
        }

        @Override
        protected void onDestroy() {
            super.onDestroy();
            dao.close();
        }

        @Override
        public void onListItemClick(ListView l, View view, int position, long id) {
            // TODO something on item click

        }
    }

请使用匹配父项而不是填充父项,因为它在材料设计中已被弃用
