十九、android中判断sim卡状态和读取联系人资料的方法

在写程序中，有时候可能需要获取sim卡中的一些联系人资料。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);

                 mString = "无卡";  

                 // do something  

                 break;

                 mString = "需要NetworkPIN解锁";  

                 // do something  

   

                 break;  

   

             case TelephonyManager.SIM_STATE_PIN_REQUIRED:  

                 mString = "需要PIN解锁";  

                 // do something  

                 break;  

   

             case TelephonyManager.SIM_STATE_PUK_REQUIRED:

                 // do something  

                 break;  

   

             case TelephonyManager.SIM_STATE_READY:  

                 mString = "良好";  

                 // do something  

                 break;
