標題中帶有複選框的自定義對話框

Question

我試圖通過DialogFragment創建一個自定義對話框。 我想要一個標題和一個複選框。

我用一個自定義標題如下

<?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> 

這樣現在我想引用此此複選框並添加一個偵聽的複選框。

我想要實現這樣的

我曾嘗試？

我不知道我們如何可以包括一個setCustomTitle佈局定製對話框

Answer 1

現在我想引用此此複選框和監聽器添加到 複選框。

我假設你展示使用DialogFragment的onCreateDialog方法的對話框，所以在onCreateDialog方法，你會怎麼做：

// inflate the layout title 
View customTitle = inflater.inflate(R.layout.custom_title, null); 
// find the CheckBox and set the listener 
CheckBox ckb = (CheckBox) customTitle.findViewById(R.id.checkBox1); 
ckb.setOnCheckedChangeListener(new ...); 
// set the title view on the dialog etc
