Android 自定义控件

package net.etmobile.widget;

import net.etmobile.R;

public class SubText extends LinearLayout {
    private final static String TAG = "SubText";

    private TextView titleTextView;
    private TextView subTextView;
    private View mView;
    private OnClickListener mClickListener;
    

    public SubText(Context context) {
        super(context);
    }

    public SubText(Context context, AttributeSet attrs) {
        super(context, attrs);

        LayoutInflater layoutInflater = LayoutInflater.from(context);
        mView = layoutInflater.inflate(R.layout.widget_subtext, this);
        
        LinearLayout linear = (LinearLayout)mView.findViewById(R.id.widget_subtext);
        linear.setOnClickListener(new OnClickListener() {
            
            public void onClick(View v) {
                Log.d(TAG,"LinearLayout click");    
                if (mClickListener != null)
                    mClickListener.onClick(SubText.this);
            }
        });

        titleTextView = (TextView) findViewById(R.id.sub_title);
        subTextView = (TextView) findViewById(R.id.sub_text);
        
        TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.SubText);
        setTitleText(a.getString(R.styleable.SubText_titleText));
        setSubText(a.getString(R.styleable.SubText_subText));
        a.recycle();
    }

    public CharSequence getTitleText() {
        return titleTextView.getText();
    }

    public void setTitleText(CharSequence titleTextView) {
        this.titleTextView.setText(titleTextView);
    }

    public CharSequence getSubText() {
        return subTextView.getText();
    }

    public void setSubText(CharSequence subTextView) {
        this.subTextView.setText(subTextView);
    }

    @Override
    public void setOnClickListener(OnClickListener l) {
        if (!isClickable()) {
            setClickable(true);
        }
        mClickListener = l;
    }

    @Override
    public String toString() {
        return getTitleText() + "/" + getSubText();
    }
}

XML layout 布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/widget_subtext"
    style="@style/form_item"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:descendantFocusability="blocksDescendants"
    android:focusable="true"
    android:clickable="true"
    android:orientation="vertical" >

    <TextView
android:id="@+id/sub_title"
        style="@style/textLarge"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="0.5"
        android:ellipsize="end"
        android:clickable="false"
        android:focusable="false"
        android:gravity="bottom|left"
        android:singleLine="true" />

    <TextView
android:id="@+id/sub_text"
        style="@style/textMedium"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="0.5"
        android:clickable="false"
        android:focusable="false"
        android:gravity="top|left" />

</LinearLayout>

在values下定义一个XML文件，一般为 attrs.xml 

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="SubText">
        <attr name="titleText" format="reference|string"></attr>
        <attr name="subText" format="reference|string"></attr>
        <attr name="Oriental">
            <enum name="Horizontal" value="1"></enum>
            <enum name="Vertical" value="0"></enum>
        </attr>
    </declare-styleable>
</resources>

使用方式

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ns="http://schemas.android.com/apk/res/net.etmobile"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <net.etmobile.widget.SubText
　　　　 android:id="@+id/pue_wom_inf_id_no"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ns:subText="xxxxx"
        ns:titleText="xxxx" />

    <net.etmobile.widget.SubText
　　　　 android:id="@+id/pue_wom_inf_no_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ns:subText="xxxxx"
        ns:titleText="xxxx" />

    <net.etmobile.widget.SubText
　　　　 android:id="@+id/pue_wom_inf_no1_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ns:subText="xxxxx"
        ns:titleText="xxxx" />

</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。
