android – 联系人选择器,检索姓氏,名字,电话号码

现在,我可以检索电话号码并将editText的文本设置为该号码.但是,当我尝试获取姓氏或名字时,它不起作用.请注意我评论的内容.

继承我的代码：

import android.app.Activity;
import android.content.Intent;
import android.database.cursor;
import android.net.Uri;
import android.os.bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.view.View;
import android.widget.button;
import android.widget.EditText;

public class main extends Activity {

    private static final int CONTACT_PICKER_RESULT = 1001; 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.main);
        Button getContacts = (Button)findViewById(R.id.getContacts);
        getContacts.setOnClickListener(new View.onClickListener() {

            @Override
            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
                startActivityForResult(i,CONTACT_PICKER_RESULT);

            }
        });
    }
    protected void onActivityResult(int reqCode,int resultCode,Intent data) {
        super.onActivityResult(reqCode,resultCode,data);
        if(resultCode == RESULT_OK) {

                    int numberIdx = cursor.getcolumnIndex(Phone.DATA);  

                    if(cursor.moveToFirst()) {
                        number = cursor.getString(numberIdX);
                        //lastName = cursor.getString(cursor.getcolumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_Name));
                    } else {
