Question

我正在尝试将标题图片放在listView可点击的顶部。

records.xml

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#efefef"
    android:orientation="vertical" >

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

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginTop="95dp"
        android:cacheColorHint="#00000000"
        android:divider="@android:color/black"
        android:dividerHeight="1.0sp"
        android:textColor="#000000" />

</RelativeLayout>

header.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/headerImage"
    android:layout_width="fill_parent"
    android:layout_height="90dp"
    android:background="@drawable/header"
    android:clickable="true"
    android:scaleType="fitXY" >

</RelativeLayout>

活动内部实施

layoutInflator=(LayoutInflater)getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

        CustomAdapter adapter = new CustomAdapter(this, R.layout.list,R.id.imageStatus, data);
        ListView listView=getListView();


        //LayoutInflater inflater = getLayoutInflater();
        //ViewGroup header = (ViewGroup)layoutInflator.inflate(R.layout.header, listView, false);
        //listView.addHeaderView(header, null, false);
        View itemView = layoutInflator.inflate(R.layout.header,listView);
        ImageView txt = (ImageView)itemView.findViewById(R.id.headerImage);
        txt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(PickupList.this,"header has been pressed", 
                        Toast.LENGTH_LONG).show();

            }
        });

        setListAdapter(adapter);

logcat的

Answer 1

请，请不要尝试自己将View放入ListView。在发布之前，使用已注释掉的ListView的内置addHeaderView方法和 PLEASE read the documentation

在文档中，它明确指出最后一个布尔参数确定标题视图是否可点击。在上面的代码中，您将其设置为false。

Answer 2

headerImage是一个相对布局，你可以只使用标准视图类（每个视图都继承自）并仍然使用setOnClickListener方法

    View txt = itemView.findViewById(R.id.headerImage);
    txt.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // use the getContext() method from the v param
            Toast.makeText(v.getContext(),"header has been pressed", 
                    Toast.LENGTH_LONG).show();

        }
    });

无法使ListView标头可点击
