在寫程序中，有時候可能需要獲取sim卡中的一些聯系人資料。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。

????? 讀取的代碼如下：

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)); Uri uri = intent.getData(); mCursor = getContentResolver().query(uri, null, null, null, null); if(mCursor == null){ mString += "不能從" + str + "讀數據\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 += "列數：" + mCursor.getColumnCount() + "\n"; mString += "行數：" + mCursor.getCount() + "\n"; if (mCursor != null) { while (mCursor.moveToNext()) { // 取得聯系人名字 int nameFieldColumnIndex = mCursor.getColumnIndex("name"); mString += mCursor.getString(nameFieldColumnIndex)+" "; // 取得電話號碼 int numberFieldColumnIndex = mCursor .getColumnIndex("number"); mString += mCursor.getString(numberFieldColumnIndex)+" "; // 取得郵箱 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); int simState = mTelephonyManager.getSimState(); switch (simState) { case TelephonyManager.SIM_STATE_ABSENT: mString = "無卡"; // do something break; case TelephonyManager.SIM_STATE_NETWORK_LOCKED: mString = "需要NetworkPIN解鎖"; // do something break; case TelephonyManager.SIM_STATE_PIN_REQUIRED: mString = "需要PIN解鎖"; // do something break; case TelephonyManager.SIM_STATE_PUK_REQUIRED: mString = "需要PUN解鎖"; // do something break; case TelephonyManager.SIM_STATE_READY: mString = "良好"; // do something break; case TelephonyManager.SIM_STATE_UNKNOWN: mString = "未知狀態"; // do something break; } mTextView.setText(mString); } }

?

main.xml布局文件如下： <?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" > <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </ScrollView> </LinearLayout>

同時還要在AndroidManefist.xml中添加讀sim卡的權限，如下：

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.test" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".PhoneTest" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission> </manifest>

?

以后一定會用到。。
