<?xml version="1.0" encoding="utf-8"?>
<resources><declare-styleable name="MyCompoundView"><attr name="et_hint" format="reference|string"></attr><attr name="bt_text" format="reference|string"></attr></declare-styleable></resources>

1.2>复合控件布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><EditTextandroid:id="@+id/newItem_et"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"/><Buttonandroid:id="@+id/done_bt"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout>

效果为：

package com.demo.cxc.compoundview;import android.content.Context;
import android.content.res.TypedArray;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;/*** Created by CXC on 15/4/12.*/
public class MyCompoundView extends LinearLayout {private EditText newItem_et;private Button done_bt;OnButtonClickListener buttonClickListener;public MyCompoundView(Context context) {super(context);init(null,0);}public MyCompoundView(Context context, AttributeSet attrs) {/*---注意调用的父类构造函数形式，如果使用super(context);在Activity中通过findFragmentById()or findFragmentByTag()时返回Null，进而使用该Fragment时会出现NullPointerException*/super(context,attrs);init(attrs,0);}private void init(AttributeSet attrs, int defStyles) {//使用布局资源填充视图LayoutInflater layoutInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);View view = layoutInflater.inflate(R.layout.compound_view_layout, this, true);//获得对子控件的引用newItem_et = (EditText) view.findViewById(R.id.newItem_et);done_bt = (Button) view.findViewById(R.id.done_bt);//获取设置的各个属性final TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.MyCompoundView, defStyles, 0);String newItem_et_hint = a.getString(R.styleable.MyCompoundView_et_hint);String done_bt_text = a.getString(R.styleable.MyCompoundView_bt_text);//设置属性值newItem_et.setHint(newItem_et_hint);done_bt.setText(done_bt_text);done_bt.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if(buttonClickListener==null){return ;}//调用listenerbuttonClickListener.onButtonClick(newItem_et.getText().toString());newItem_et.setText("");}});}public void setOnButtonClickListener(OnButtonClickListener listener) {this.buttonClickListener = listener;}public interface OnButtonClickListener {public void onButtonClick(String newItemString);}}

2>使用该复合控件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<!--使用该组合控件-->
<!--xmlns:cv="http://schemas.android.com/apk/res/AndroidManifest文件中的package属性值"-->
<com.demo.cxc.compoundview.MyCompoundView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cv="http://schemas.android.com/apk/res/com.demo.cxc.compoundview"
android:id="@+id/new_item"
android:layout_width="match_parent"
android:layout_height="wrap_content"
cv:bt_text="@string/done_bt_text"
cv:et_hint="@string/new_item_et_hint"/>
<TextView
android:id="@+id/show_tv"
android:text="Show Text..."
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>

<resources><string name="app_name">CompoundView</string><string name="action_settings">Settings</string><string name="done_bt_text">Done</string><string name="new_item_et_hint">Please input what you want to do ...</string>
</resources>

2.2>ＭainActivity代码

import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
