android讀取sim聯系人資料的代碼

在獲取sim卡聯系人前，我們一般會先判斷sim卡狀態，找到sim卡后再獲取它的資料，如下代碼我們可以讀取sim卡中的聯系人的一些信息。

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"); //一般用這一條，如果這條不行的話可以試試下面的一條。  
        getSimContacts("content://sim/adn");//此種讀法在我們手機里不能讀取，所以，還是用上個uri比較好。  
    }  
    mTextView.setText(mString);  
}  

private void getSimContacts(String str){  
    Intent intent = new Intent();  
    intent.setData(Uri.parse(str));

    mCursor = getContentResolver().query(uri, null, null, null, null);  
    if(mCursor == null){  
        mString += "不能從" + str + "讀數據\n";  
        return ;  
    }

            // 取得聯系人名字  
            int nameFieldColumnIndex = mCursor.getColumnIndex("name");  
            mString += mCursor.getString(nameFieldColumnIndex)+"    ";

                    .getColumnIndex("number");

            // 取得郵箱  
            int emailsFieldColumnIndex = mCursor  
                    .getColumnIndex("emails");  
            mString += mCursor.getString(emailsFieldColumnIndex)+"    ";  
            // 取得id

                    .getColumnIndex("_id");  
            mString += mCursor.getString(idFieldColumnIndex)+"\n";  
        }  
    }  
    mString += mCursor + "\n";  
    mCursor.close();
