Question

我正在尝试通过DialogFragment创建一个自定义对话框。我想要一个标题和一个复选框。

我这样做是通过使用自定义标题，如下所示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:paddingTop="5dp" >

    <TextView
        android:id="@+id/textView1"
        style="?android:attr/textAppearanceLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:paddingLeft="15dp"
        android:text="Categories"
        android:textColor="#ffffff"
        android:textSize="22sp" />

    <TextView
        android:id="@+id/all"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="All"
        android:textColor="#ffffff" />

    <CheckBox
        android:id="@+id/checkBox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:paddingRight="10dp"/>

</LinearLayout>

现在我想引用此复选框并向Checkbox添加一个监听器。

我想实现类似的目标

我不确定如何为自定义对话框

添加setCustomTitle布局

Answer 1

现在我想引用此复选框并添加一个监听器复选框。

我假设您使用DialogFragment的{{1}}方法显示对话框，因此您可以使用onCreateDialog方法：

onCreateDialog

标题中带有复选框的自定义对话框
