this DetailActivity already have extra data from the previous activity, but i need to pass extra data "idm" to Kuisioner Activity. can anyone teach me how to do that? please this is really important to me :(
Declare String MhsID as class level member field like,
public class DetailActivity extends Activity {
private String MhsID = null;
Now in showInfo get Intent data like,
public void showInfo(){
....
Intent intent = getIntent();
MhsID = intent.getStringExtra("idm");
....
And pass values of MhsID to Kuisioner Activity using putExtra() via Intent as you did in previous activity
btnKuis.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent kuis = new Intent(DetailActivity.this, Kuisioner.class);
kuis.putExtra("idm",MhsID);
startActivity(kuis);
}
});
And get String idm in Kuisioner Activity same as this activity.
in DetailActivity.java:
Intent kuis = new Intent(DetailActivity.this, Kuisioner.class);
kuis.putExta("Key_hossam", "value"); // just add this line
startActivity(kuis);
in Kuisioner.java:
inside the onCreate method just write these lines
Intent intent= getIntent();
Bundle b = intent.getExtras();
if(b!=null)
{
String value =(String) b.get("Key_hossam");
}
}
It is all explained HERE.
Just add this line of code:
intent.putExtra(name, value);
So starting new Kuisioner activity should look like this:
String value = "Example value"
Intent kuis = new Intent(DetailActivity.this, Kuisioner.class);
kuis.putExtra("idm", value);
startActivity(kuis);
If you are working with too many variables, and want to pass data among activities, I suggest make your Activity-variables static , and use with class name, no more maintaining variables.
Note : I assume you are using Fragments, you may come back to activities again n again.

Here is the problem, you execute your network calls when the button is clicked, and new intent is directly started without waiting for network call's response, so it will not work for the first time.
Solution is to chain the operation in the Submit button's onClick validation stuff.
To chain the operations, extract this code block like this,
public void goToNextActivity(){
nameee = name.getText().toString().trim();
if (TextUtils.isEmpty(name.getText().toString())) {
return;
}
ad = addresssss.getText().toString();
if (TextUtils.isEmpty(addresssss.getText().toString())) {
return;
}
ad1 = address1111.getText().toString();
if (TextUtils.isEmpty(address1111.getText().toString())) {
return;
}
ci = city.getText().toString();
if (TextUtils.isEmpty(city.getText().toString())) {
return;
}
sta = state.getText().toString();
if (TextUtils.isEmpty(state.getText().toString())) {
return;
}
cou = country.getText().toString();
if (TextUtils.isEmpty(country.getText().toString())) {
return;
}
pos = postalcode.getText().toString();
if (TextUtils.isEmpty(postalcode.getText().toString())) {
return;
}
land = landmark.getText().toString().trim();
if (TextUtils.isEmpty(landmark.getText().toString())) {
return;
}
nameeee=mobiles.getText().toString().trim();
if (TextUtils.isEmpty(mobiles.getText().toString())) {
return;
}
else {
Intent intent = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intent);
}
}
then call this method from asynctask's protected void onPostExecute(String result).
#Override
protected void onPostExecute(String result) {
try {
object = new JSONObject(result);
ggg = object.getString("customer_id");
Log.d("customer",ggg);
SharedPreferences.Editor editt = sharedPreferences.edit();
editt.putString("CUSTOMER_ID", ggg);
editt.apply();
//**after all needed data is persisted to preferences.**
goToNextActivity();
} catch (JSONException e) {
e.printStackTrace();
}
}
Hope this help.
I have just started Android and i am working on Simple Login Page,where user can use their email and password to login with some conditions while login. When user login as a "store owner",his name and email is shown on the next page (i.e on the Fragment class) which is working fine but whenever user login as a "public user",his name and email is not showing on the next page.
Note: I am using webservices and SharedPreferences to fetch and save data.

try this to set Shared Pref

You have to use a bundle and a serializable object to pass.:
From the activity:
Fragment fragment = new YourFragment();
Bundle bundle = new Bundle();
bundle.putSerializable(ARGUMENT_KEY, objectSerializable);
fragment.setArguments(bundle); showFragment(fragment)
On the fragment:
Bundle bundle = this.getArguments();
if (bundle != null) {
Object neededObject = bundle.getSerializable(ser_key)
}
Override newInstance() method in your fragment like this.
public static YourFragment newInstance(Bundle bundle) {
ActivityFeedListFragment fragment = new ActivityFeedListFragment();
fragment.setArguments(bundle);
return fragment;
}
And pass bundle object.
I have android app for login, when user gives login details that data have to pass in multiple activities.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username=(EditText)findViewById(R.id.user_name);
passwrd=(EditText)findViewById(R.id.Pass_word);
login=(Button)findViewById(R.id.Login);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email = username.getText().toString();
String password = passwrd.getText().toString();
new Mytask().execute(email, password);
}
});
}
I want to pass email and password to multiple activities..
I just tried Bundle.
I stored email value as "name".
And i just passed the value to another activity(Below code).

String name = b.getString("name");
new Mytask().execute(name,Text);
}
});

Email has passed as "name"(bundle).
"name" value passed as params[0] to my php file.
But params[0] not passed to my php file.
Could you please help me with this. Thank you.
You should probably use SharedPreferences instead of Bundle.
Save data like this:
SharedPreferences sPref;
sPref = getPreferences(MODE_PRIVATE);
Editor ed = sPref.edit();
ed.putString("email", etText.getText().toString());
ed.putString("password", etText.getText().toString());
ed.commit();
And get it in your activities like this:
sPref = getPreferences(MODE_PRIVATE);
String email = sPref.getString("email", "");
String password = sPref.getString("password", "");
etText.setText(savedText);
And I also recommend you to use it in separate thread.
In my project , to access the webservice am using http class which is not working properly and my project stops.
Can someone tell me an alternate way for accessing the webservice instead of using http.
Thank you in advance

You can do this way:
AsyncTask for Web service:
private class AsyncCaller extends AsyncTask<Void, Void, Void>
{
ProgressDialog pdLoading = new ProgressDialog(AsyncExample.this);
#Override
protected void onPreExecute() {
super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("Loading...");
pdLoading.show();
}
#Override
protected Void doInBackground(Void... params) {
String serverGETResponse = getJsonDataStringFormat("Your_Url", "GET", "", "LOGIN_ACTIVITY");
String serverPOSTResponse = getJsonDataStringFormat("Your_Url", "POST", "YOUR_JSON_STRING", "LOGIN_ACTIVITY");
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
//this method will be running on UI thread
pdLoading.dismiss();
}
}
Now Get Response from server in Background thread:
public static String getJsonDataStringFormat(String url, String method,String jObjStr, String tag) {
InputStream is = null;
String Root_Response = null;
HttpResponse httpResponse;
HttpParams httpParameters = new BasicHttpParams();
DefaultHttpClient httpClient;
HttpConnectionParams.setConnectionTimeout(httpParameters,connectionTimeOut);
HttpConnectionParams.setSoTimeout(httpParameters, socketTimeOut);
try {
httpClient = new DefaultHttpClient(httpParameters);
url = url.replace(" ", "%20");
if (method == "POST") {
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new StringEntity(jObjStr));
httpResponse = httpClient.execute(httpPost);
is = httpResponse.getEntity().getContent();
} else if (method == "GET") {
HttpGet httpGet = new HttpGet(new URI(url));
httpResponse = httpClient.execute(httpGet);
is = httpResponse.getEntity().getContent();
}
Root_Response = convertStreamToString(is);
Log.i(tag, Root_Response);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}catch (URISyntaxException e) {
e.printStackTrace();
}
return Root_Response;
}
Convert Server's Response to String:
public static String convertStreamToString(InputStream inputStream)
throws IOException {
if (inputStream != null) {
StringBuilder sb = new StringBuilder();
String line;
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(inputStream, "UTF-8"));
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
} finally {
inputStream.close();
}
return sb.toString();
} else {
return "";
}
}
Hope it will help you.
call the method server_conn() inside AsyncTask , and pass the url
private class AsyncTaskTest extends AsyncTask<String, Void, Void>
{
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected Void doInBackground(String... strings) {
server_conn(strings[0]);
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
}
}
and call the asynctastk using below syntax
new AsyncTaskTest().execute(url);
You are facing NetworkOnMainThread exception all you have to do is add this code :
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.detectAll()
.penaltyLog()
.build();
StrictMode.setThreadPolicy(policy);
For more details you can check developer site.
I want to return a value from AsyncTask and I want to compare with the value contents and at the and if they match I want to send the value where I take it from AsyncTasnk to the other intent. I hope I explained it properly.
and this is the code :
public class MainActivity extends Activity {
Button ButtonClick;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView txt = (TextView) findViewById(R.id.textView1);
ButtonClick = (Button) findViewById(R.id.qrReader);
ButtonClick.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(
"com.google.zxing.client.android.SCAN");
startActivityForResult(intent, 0);
MainActivity.this.runOnUiThread(new Runnable() {
public void run() {
GetProduts GP = new GetProduts();
txt.setText(GP.execute().toString());
}
});
// Intent i = new Intent(MainActivity.this,IndexActivity.class);
// startActivity(i);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
final String contents = intent.getStringExtra("SCAN_RESULT");
//I want to compare this value
}
} else if (resultCode == RESULT_CANCELED) {
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public class GetProduts extends AsyncTask<ArrayList<Product>, Void, ArrayList<Product>> {
Product p;
final ArrayList<Product> productIdList = new ArrayList<Product>();
#Override
protected ArrayList<Product> doInBackground(ArrayList<Product>... params) {
HttpClient httpclient = new DefaultHttpClient();
GeneralConstans GC = new GeneralConstans();
// Products will be stated in memory
HttpPost httpget = new HttpPost(GC.UrlProducts);
HttpResponse response;
String result = null;
try {
HttpContext ctx = new BasicHttpContext();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
httpget.setEntity(new UrlEncodedFormEntity(nameValuePairs,
"UTF-8"));
response = httpclient.execute(httpget, ctx);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
result = EntityUtils.toString(resEntity);
JSONArray arr = new JSONArray(result);
Gson gson = new Gson();
if (arr.length() > 0) {
for (int j = 0; j < arr.length(); j++) {
p = gson.fromJson(arr.getString(j), Product.class);
productIdList.add(p);
}
}
return productIdList;
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (SocketException e) {
/*
* if (checkAbortStatus(e.getMessage()) == true) {
* handler.sendEmptyMessage(0); }
*/
} catch (IOException e) {
/*
* if (checkAbortStatus(e.getMessage()) == true) {
* handler.sendEmptyMessage(0); }
*/
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(ArrayList<Product> result) {
super.onPostExecute(result);
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
}
}
Declare contents under Button ButtonClick; as:
String contents = "";
In onActivityResult(), replace:
final String contents = intent.getStringExtra("SCAN_RESULT");
with:
contents = intent.getStringExtra("SCAN_RESULT");
result in onPostExecute(ArrayList<Product> result) is productIdList. Change your onPostExecute() to:
#Override
protected void onPostExecute(ArrayList<Product> result) {
super.onPostExecute(result);
if (result != null) {
for (int i = 0; i < result.size(); i++) {
if(result.get(i).toString().equals(contents) {
// Do something
}
}
}
}
Also, the following doesn't look correct:
public void run() {
GetProduts GP = new GetProduts();
txt.setText(GP.execute().toString());
}
Instead try this:
public void run() {
new GetProduts().execute();
}
And declare txt as TextView txt; under Button ButtonClick;. Now, add the following line to your onPostExecute():
txt.setText(....); // Replace .... with whatever you are trying to set.
Edit 1:
To start another activity:
if(result.get(i).toString().equals(contents) {
// Change "OtherActivity" to the name of the activity you want to start
Intent newIntent = new Intent(MainActivity.this, OtherActivity.class);
newIntent.putExtra("My_Extra", result.get(i).toString());
startActivity(newIntent);
}
To retrieve this String in the other activity:
String extraString = getIntent().getStringExtra("My_Extra");
