Android Retrofit + ProgressDialog在获取大数据时冻结
我创建了一个有100k +记录的api。我已经完成了我的工作，每个请求获得数万个记录块。
根据逻辑部分如果我得到 flag = true 它将再次发送请求。
CODE：
创建ProgressDialog：
/**
* First Sync Progressbar
*/
progressDialog = new ProgressDialog(NavigationActivity.this);
progressDialog.setTitle("Please wait...");
progressDialog.setMessage("Synchronizing...");
progressDialog.setCancelable(false);
首次同步功能：
private void doFirstSync(final String authToken) {
try {
runOnUiThread(new Runnable() {
@Override
public void run() {
if (progressDialog != null && !progressDialog.isShowing())
progressDialog.show();
}
});
Cursor tableCursor = getContentResolver().query(KOOPSContentProvider.CONTENT_URI_TABLES, null, null, null, null);
JSONArray array = new JSONArray();
if (tableCursor != null) {
JSONObject object = new JSONObject();
if (tableCursor.getCount() > 0) {
while (tableCursor.moveToNext()) {
object.put(TTables.TABLE_NAME,
tableCursor.getString(tableCursor.getColumnIndex(TABLE_NAME)));
object.put(TTables.TABLE_UTP,
tableCursor.isNull(tableCursor.getColumnIndex(TABLE_UTP)) ? ""
: tableCursor.getString(tableCursor.getColumnIndex(TABLE_UTP)));
object.put(TTables.TABLE_LAST_ID,
tableCursor.isNull(tableCursor.getColumnIndex(TABLE_LAST_ID)) ? ""
: tableCursor.getString(tableCursor.getColumnIndex(TABLE_LAST_ID)));
array.put(object);
object = new JSONObject();
}
}
Log.d(TAG, "Array of Table : " + array.toString());
tableCursor.close();
}
firstSyncCall = retrofitInterfaces.firstSync(authToken, array.toString(), KOOPS.getDeviceId(getApplicationContext()));
firstSyncCall.enqueue(new MyCallback<FirstSync>(NavigationActivity.this) {
@Override
public void onSuccess(final FirstSync firstSync) {
boolean isSendAgain = firstSync.getFlag();

问题：
- 在加载/获取/插入数据时冻结ProgerssBar。
- 使用ContentProvider *进行批量插入是否有其他最佳方法，因为插入10000条记录也需要150秒？
