android - 自定义视图从 Button 窃取焦点

Question

这是我用于布局的 xml 文件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/idtop"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="@color/black"
android:orientation="vertical" >

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#00ff00"
    android:gravity="center_horizontal" >

    <TextView
        android:id="@+id/idalarmtime"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingBottom="30dip"
        android:paddingTop="30dip"
        android:textColor="@color/white"
        android:textSize="100sp" />
</RelativeLayout>

<RelativeLayout
    android:id="@+id/lclock"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#ff0000" >

    <Button
        android:id="@+id/idsnooze"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"

        android:background="@color/black"
        android:paddingBottom="30dip"
        android:text="Snooze"
        android:textColor="@color/white" />

    <Button
        android:id="@+id/iddismiss"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"

自定义视图包com.exercise.AndroidAlarmService的代码；

我正在尝试做的事情 -我有一个 id 为“layc”的线性布局。我正在创建一个新视图，并使用 addView 添加到此 LinearLayout 中。此自定义视图是可拖动的。当我拖动它关闭时，将调用一个函数。

问题 -添加新视图时，贪睡和关闭按钮未收到 onTouch / onClick 事件
