我需要检索具有 <=7 个字符的联系人 ID，并在前面添加两个 0 并更新联系人列表。我怎样才能做到这一点

public class MainActivity extends Activity {

    public static final int PICK_CONTACT    = 1;
    Uri uri;
    TextView txt_contacts;
    Cursor c = null;
    MainActivity context;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        context=this;


        getContactList();


        // this opens the activity. note the  Intent.ACTION_GET_CONTENT
        // and the intent.setType
        ((Button)findViewById(R.id.btn_contacts)).setOnClickListener( new OnClickListener() {
            @Override
            public void onClick(View v) {
                // user BoD suggests using Intent.ACTION_PICK instead of .ACTION_GET_CONTENT to avoid the chooser
                Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
                // BoD con't: CONTENT_TYPE instead of CONTENT_ITEM_TYPE
                intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
                startActivityForResult(intent, 1);  
                txt_contacts =(TextView)findViewById(R.id.txt_contacts);


            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (data != null) {
            uri = data.getData();

            if (uri != null) {

你可能想看看这个： How to get contacts from native phonebook in android

对于您的情况，您只需将 SELECTION 查询语句更改为：

Uri contactUri = ContactsContract.Contacts.CONTENT_URI;
String[] PROJECTION = new String[] {
    ContactsContract.Contacts._ID,
    ContactsContract.Contacts.DISPLAY_NAME,
};
String SELECTION = "LENGTH(" + ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + ")<='4'";
Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, SELECTION, null, null);
