Android 自定义控件

 8     private TextView titleTextView;

10     private View mView;

13 
14     public SubText(Context context) {
15         super(context);
16     }
17 
18     public SubText(Context context, AttributeSet attrs) {
19         super(context, attrs);
20 
21         LayoutInflater layoutInflater = LayoutInflater.from(context);
22         mView = layoutInflater.inflate(R.layout.widget_subtext, this);

29                 if (mClickListener != null)
30                     mClickListener.onClick(SubText.this);
31             }

67     @Override
68     public String toString() {
69         return getTitleText() + "/" + getSubText();

XML layout 布局文件

 1 xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:id="@+id/widget_subtext"
 4     style="@style/form_item"
 5     android:layout_width="fill_parent"
 6     android:layout_height="match_parent"
 7     android:descendantFocusability="blocksDescendants"
 8     android:focusable="true"
 9     android:clickable="true"
10     android:orientation="vertical" >
11 
12     <TextView
13 android:id="@+id/sub_title"
14         style="@style/textLarge"
15         android:layout_width="fill_parent"
16         android:layout_height="0dp"
17         android:layout_weight="0.5"
18         android:ellipsize="end"
19         android:clickable="false"
20         android:focusable="false"
21         android:gravity="bottom|left"
22         android:singleLine="true" />
23 
24     <TextView
25 android:id="@+id/sub_text"
26         style="@style/textMedium"
27         android:layout_width="fill_parent"
28         android:layout_height="0dp"
29         android:layout_weight="0.5"
30         android:clickable="false"
31         android:focusable="false"
32         android:gravity="top|left" />
33 
34 LinearLayout>

在values下定义一个XML文件，一般为 attrs.xml 

 1 xml version="1.0" encoding="utf-8"?>
 2 <resources>
 3     <declare-styleable name="SubText">
 4         <attr name="titleText" format="reference|string">attr>
 5         <attr name="subText" format="reference|string">attr>
 6         <attr name="Oriental">
 7             <enum name="Horizontal" value="1">enum>
 8             <enum name="Vertical" value="0">enum>
 9         attr>
10     declare-styleable>
11 resources>

使用方式

 1 xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     xmlns:ns="http://schemas.android.com/apk/res/net.etmobile"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:orientation="vertical" >
 7 
 8     <net.etmobile.widget.SubText
 9 　　　　 android:id="@+id/pue_wom_inf_id_no"
10         android:layout_width="wrap_content"
11         android:layout_height="wrap_content"
12         ns:subText="xxxxx"
13         ns:titleText="xxxx" />
14 
15     <net.etmobile.widget.SubText
16 　　　　 android:id="@+id/pue_wom_inf_no_id"
17         android:layout_width="wrap_content"
18         android:layout_height="wrap_content"
19         ns:subText="xxxxx"
20         ns:titleText="xxxx" />
21 
22     <net.etmobile.widget.SubText
23 　　　　 android:id="@+id/pue_wom_inf_no1_id"
24         android:layout_width="wrap_content"
25         android:layout_height="wrap_content"
26         ns:subText="xxxxx"
27         ns:titleText="xxxx" />
28 
29 LinearLayout>

注意 xmlns:ns="http://schemas.android.com/apk/res/net.etmobile" 其中 net.etmobile 是你的工程包名，不是widget所在的包名

解决外部不能监听用户单击的问题的方式比较恶心，我一直觉得有其它的方式可以解决这种问题，求高人指点。
