     1 package net.etmobile.widget;
    2
    3 import net.etmobile.R;
    4
    5 public class SubText extends LinearLayout {
    6 private final static String TAG = "SubText";
    7
    8 private TextView titleTextView;
    9 private TextView subTextView;
    10 private View mView;
    11 private OnClickListener mClickListener;
    12
    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);
    23
    24 LinearLayout linear = (LinearLayout)mView.findViewById(R.id.widget_subtext);
    25 linear.setOnClickListener(new OnClickListener() {
    26
    27 public void onClick(View v) {
    28 Log.d(TAG,"LinearLayout click");
    29 if (mClickListener != null)
    30 mClickListener.onClick(SubText.this);
    31 }
    32 });
    33
    34 titleTextView = (TextView) findViewById(R.id.sub_title);
    35 subTextView = (TextView) findViewById(R.id.sub_text);
    36
    37 TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.SubText);
    38 setTitleText(a.getString(R.styleable.SubText_titleText));
    39 setSubText(a.getString(R.styleable.SubText_subText));
    40 a.recycle();
    41 }
    42
    43 public CharSequence getTitleText() {
    44 return titleTextView.getText();
    45 }
    46
    47 public void setTitleText(CharSequence titleTextView) {
    48 this.titleTextView.setText(titleTextView);
    49 }
    50
    51 public CharSequence getSubText() {
    52 return subTextView.getText();
    53 }
    54
    55 public void setSubText(CharSequence subTextView) {
    56 this.subTextView.setText(subTextView);
    57 }
    58
    59 @Override
    60 public void setOnClickListener(OnClickListener l) {
    61 if (!isClickable()) {
    62 setClickable(true);
    63 }
    64 mClickListener = l;
    65 }
    66
    67 @Override
    68 public String toString() {
    69 return getTitleText() + "/" + getSubText();
    70 }
    71 }

    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。
