接着上一篇，本篇玩一下自定义LinearLayout，直接上代码：

1. attr.xml

2.继承LinearLayout重新定义一个：

package com.test.customviewtest;

import android.content.Context;

import android.content.res.TypedArray;

import android.util.AttributeSet;

import android.widget.EditText;

import android.widget.LinearLayout;

import android.widget.TextView;

public class MyLinearLayout extends LinearLayout {

public MyLinearLayout(Context context, AttributeSet attrs) {

super(context, attrs);

int resouceId = -1;

TypedArray MyTypeArray = context.obtainStyledAttributes(attrs,

R.styleable.MyLinearLayout);

TextView tv = new TextView(context);

EditText et = new EditText(context);

int N = MyTypeArray.getIndexCount();// N=2

for (int i = 0; i < N; i++) {
</
