创建上下文菜单及监听

首先在res/menu下创建上下文菜单context_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/file_context_menu_rename"
        android:title="重命名"/>
    <item
        android:id="@+id/file_context_menu_copy"
        android:title="复制"/>
    <item
        android:id="@+id/file_context_menu_detail"
        android:title="详情"/>

</menu>

然后在Activity里注册listView的上下文菜单.

listView.setOnCreateContextMenuListener(this);

下面是上下文菜单的创建和响应.

    /**
     * 创建上下文菜单
     */
    @Override
    public void onCreateContextMenu(ContextMenu menu, View v,
            ContextMenuInfo menuInfo) {
        getMenuInflater().inflate(R.menu.schedule_context_menu, menu);
        super.onCreateContextMenu(menu, v, menuInfo);
    }

    /**
     * 上下文菜单监听
     */
    @Override
    public boolean onContextItemSelected(MenuItem item) {
        AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
                .getMenuInfo(); // info包含了上下文菜单每一项的信息,比如info.position是上下文菜单项的位置
        switch (item.getItemId()) {
        case R.id.file_context_menu_rename:
            // do something
            return true;
        case R.id.file_context_menu_copy:
            // do something
            return true;
        case R.id.file_context_menu_move:
            // do something
            return true;
        default:
            break;
        }
        return super.onContextItemSelected(item);
    }
