如何对自定义的Dialog的View中控件进行监听

//activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <Button         android:id="@+id/dialog_btn1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:text="自定义对话框"        /></LinearLayout>

//dialog_layout.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <LinearLayout        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"         >        <EditText             android:id="@+id/editText"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:hint="请输入内容"            android:layout_weight="1"            />        <Button             android:id="@+id/bt"            android:layout_marginLeft="10dp"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="提交"            />    </LinearLayout>    <ImageView         android:layout_width="match_parent"        android:layout_height="wrap_content"        android:src="@drawable/pic4"        android:layout_marginTop="10dp"        /></LinearLayout>

android:src=”@drawable/pic4” 这里的图片要选自己的图片。
