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。
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); int simState = mTelephonyManager.getSimState(); switch (simState) { case TelephonyManager.SIM_STATE_ABSENT: mString = "无卡"; // do something break; case TelephonyManager.SIM_STATE_NETWORK_LOCKED: 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: mString = "需要PUN解锁"; // do something break; case TelephonyManager.SIM_STATE_READY: mString = "良好"; // do something break; case TelephonyManager.SIM_STATE_UNKNOWN: mString = "未知状态"; // do something break; } mTextView.setText(mString); } }
