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);

    }
