这里主要用到Android API的TelephonyManager对象(Android.telephony.TelephonyManager)。以下源码就该对象的几个方法展示其用途。具体源码如下：
package com.mobile.allove.wfp;
import java.util.ArrayList;
import android.app.ListActivity;
import android.app.Service;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;
public class TelephonyManagerTest extends ListActivity implements OnClickListener{
private Button showInfoButton;
private TelephonyManager mTelephonyManager;
ArrayList SIMInfo_name=null;//显示要显示的SIM信息的名称
ArrayList SIMInfo_value=null;//显示要显示的SIM信息的名称的值
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.Init();
showInfoButton.setOnClickListener(this);
}
public void Init()
{
showInfoButton=(Button)this.findViewById(R.id.Button01);
mTelephonyManager=(TelephonyManager) this.getSystemService(Service.TELEPHONY_SERVICE);
SIMInfo_name=new ArrayList();
SIMInfo_value=new ArrayList();
//首先显示SIM卡状态
SIMInfo_name.add(this.getResources().getString(R.string.SIM_state));
if(mTelephonyManager.getSimState()==TelephonyManager.SIM_STATE_READY)
{
SIMInfo_value.add(”SIM卡状态良好！”);
}
else if(mTelephonyManager.getSimState()==TelephonyManager.SIM_STATE_ABSENT)
{
SIMInfo_value.add(”SIM卡未插入！”);
}
else
{
SIMInfo_value.add(”SIM卡被锁定或未知的状态！”);
}
//SIM卡供货商代码
SIMInfo_name.add(this.getResources().getString(R.string.SIM_code));
if(mTelephonyManager.getSimSerialNumber().equals(”"))
{
SIMInfo_value.add(”SIM卡供货商代码无法取得”);
}
else
{
SIMInfo_value.add(mTelephonyManager.getSimSerialNumber());
}
//SIM卡供货商名称
SIMInfo_name.add(this.getResources().getString(R.string.SIM_factoryname));
if(mTelephonyManager.getSimOperatorName().equals(”"))
{
SIMInfo_value.add(”SIM卡供货商名称无法取得”);
}
else
{
SIMInfo_value.add(mTelephonyManager.getSimOperatorName());
}
//SIM卡国别
SIMInfo_name.add(this.getResources().getString(R.string.SIM_country));
if(mTelephonyManager.getSimCountryIso().equals(”"))
{
SIMInfo_value.add(”SIM卡国别无法取得”);
}
else
{
SIMInfo_value.add(mTelephonyManager.getSimCountryIso());
}
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId())
{
case R.id.Button01:
this.setListAdapter(new MyAdapter());
break;
}
}
class Holder
{
TextView name_TextView;
TextView value_TextView;
}
class MyAdapter extends BaseAdapter
{
LayoutInflater inflater;
Holder mHolder;
@Override
public int getCount() {
// TODO Auto-generated method stub
return SIMInfo_name.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
inflater=LayoutInflater.from(TelephonyManagerTest.this);
if(convertView==null)
{
convertView=inflater.inflate(R.layout.item_layout,null);
mHolder=new Holder();
mHolder.name_TextView=(TextView)convertView.findViewById(R.id.item_TextView01);
mHolder.value_TextView=(TextView)convertView.findViewById(R.id.item_TextView02);
convertView.setTag(mHolder);
}
else
{
mHolder=(Holder) convertView.getTag();
}
mHolder.name_TextView.setText(SIMInfo_name.get(position));
mHolder.value_TextView.setText(SIMInfo_value.get(position));
return convertView;
}
}
}
注意加读取SIM的权限——android.permission.READ_PHONE_STATE
