android读取sim联系人资料的代码

在获取sim卡联系人前，我们一般会先判断sim卡状态，找到sim卡后再获取它的资料，如下代码我们可以读取sim卡中的联系人的一些信息。

PhoneTest.java

package com.android.test;  

import android.app.Activity;  
import android.content.Context;  
import android.content.Intent;  
import android.database.Cursor;  
import android.net.Uri;  
import android.os.Bundle;  
import android.telephony.TelephonyManager;  
import android.widget.TextView;  

public class PhoneTest extends Activity {  
    private TextView mTextView;  
    protected Cursor mCursor = null;  
    private TelephonyManager mTelephonyManager;  
    private String mString = "";  

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  
        mTextView = (TextView)findViewById(R.id.text);  
        mTextView.setTextSize(20.3f);  
        isSimExist();  
        if(getSimState() == TelephonyManager.SIM_STATE_READY){  
            mString += "    卡存在\n";  
            getSimContacts("content://icc/adn"); //一般用这一条，如果这条不行的话可以试试下面的一条。  
            getSimContacts("content://sim/adn");//此种读法在我们手机里不能读取，所以，还是用上个uri比较好。  
        }  
        mTextView.setText(mString);  
    }  

    private void getSimContacts(String str){  
        Intent intent = new Intent();  
        intent.setData(Uri.parse(str));  
        Uri uri = intent.getData();  
        mCursor = getContentResolver().query(uri, null, null, null, null);  
        if(mCursor == null){  
            mString += "不能从" + str + "读数据\n";  
            return ;  
        }  
        mString += "第一列：" + mCursor.getColumnName(0) + "\n";  
        mString += "第二列：" + mCursor.getColumnName(1) + "\n";  
        mString += "第三列：" + mCursor.getColumnName(2) + "\n";  
        mString += "第四列：" + mCursor.getColumnName(3) + "\n";  
        mString += "列数：" + mCursor.getColumnCount() + "\n";  
        mString += "行数：" + mCursor.getCount() + "\n";  
        if (mCursor != null) {  
            while (mCursor.moveToNext()) {  
                // 取得联系人名字  
                int nameFieldColumnIndex = mCursor.getColumnIndex("name");  
                mString += mCursor.getString(nameFieldColumnIndex)+"    ";  
                // 取得电话号码  
                int numberFieldColumnIndex = mCursor  
                        .getColumnIndex("number");  
                mString += mCursor.getString(numberFieldColumnIndex)+"    ";  
                // 取得邮箱  
                int emailsFieldColumnIndex = mCursor  
                        .getColumnIndex("emails");  
                mString += mCursor.getString(emailsFieldColumnIndex)+"    ";  
                // 取得id  
                int idFieldColumnIndex = mCursor  
                        .getColumnIndex("_id");  
                mString += mCursor.getString(idFieldColumnIndex)+"\n";  
            }  
        }  
        mString += mCursor + "\n";  
        mCursor.close();  
    }  

    private int getSimState(){  
        return mTelephonyManager.getSimState();  
    }  

    private void isSimExist(){  
        mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
