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 .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);
}
}
