我想从电话联系人应用程序中获取所有联系人并插入到本地 sqlite 数据库中。但问题是android接触光标需要时间来迭代......
代码:
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}
插入数据库:
long mStartTime = System.currentTimeMillis();
int batch = 50;
try {
SQLiteDatabase db = this.getWritableDatabase();
// InsertHelper insertHelper = new InsertHelper(db,
// TABLE_USER_INFO);
// String insertSql =
// "INSERT INTO UserInfo (firstname,lastname,userid,serveruserid,phonenumber,emailaddress,street,state,city,country) VALUES (?,?,?,?,?,?,?,?,?,?) ";
// SQLiteStatement sqLiteStatement = db.compileStatement(insertSql);
if (cursor != null) {
if (cursor.moveToFirst()) {
for (int i = 0; i < cursor.getCount() / batch
+ (((cursor.getCount() % batch) > 0) ? 1 : 0); i++) {
mStartTime = System.currentTimeMillis();
StringBuilder sqlBuilder = new StringBuilder();
db.beginTransaction();
sqlBuilder
.append("INSERT INTO UserInfo (firstname,lastname,userid,serveruserid,phonenumber,emailaddress,street,state,city,country) ");
for (int j = 0; j < batch; j++) {
String name = cursor
.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

插入需要4分钟....
请建议迭代光标的有效方法。
