取得手机的网络信息

在main.xml中：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

<ListView

android:layout_marginLeft="8dp"

android:layout_marginRight="8dp"

android:id="@+id/infolist"

android:layout_width="fill_parent"

android:layout_height="wrap_content" />

</LinearLayout>

在MyTelephoneManagerDemo.java中：

package com.li.telephonemanager;

this.adapter = new ArrayAdapter<String>(this,

this.infolist.setAdapter(this.adapter) ;

}

}

在AndroidManifest.xml中修改权限：
