Interface:-
I want to make a toast message, if user did not choose any subject, it will toast message "Please choose subject". There is no error, the issue was I dont know where to put the coding to display the toast message when needed.
Coding:-
#Override
public void onClick(View v) {
final MediaPlayer mediaPlayer = MediaPlayer.create(FilterTuitionCentreActivity.this, R.raw.soundeffect1);
if (v == filterButton) {
mediaPlayer.start();
filterBtnFlag = true;
if(spLocation.getSelectedItem() == null){
return;
}
/*if(!(spSubject.getSelectedItem().toString().equalsIgnoreCase("Subject")
|| spSubject.getSelectedItem().toString().equalsIgnoreCase("Choose Subject"))){
Toast.makeText(FilterTuitionCentreActivity.this, "Please choose subject.", Toast.LENGTH_SHORT).show();
}*/
else {
loadFilteredInstitutesList("Advertisement");
}
}
}
You need a move that validation logic up and return without go further if any validation fails.
#Override
public void onClick(View v) {
//add your spinner validity checking here
if(!(spSubject.getSelectedItem().toString().equalsIgnoreCase("Subject")
||
spSubject.getSelectedItem().toString().equalsIgnoreCase("Choose Subject"))){
Toast.makeText(FilterTuitionCentreActivity.this, "Please choose subject.", Toast.LENGTH_SHORT).show();
return;
}
final MediaPlayer mediaPlayer = MediaPlayer.create(FilterTuitionCentreActivity.
this, R.raw.soundeffect1);
if (v == filterButton) {
mediaPlayer.start();
filterBtnFlag = true;
if(spLocation.getSelectedItem() == null){
return;
}
loadFilteredInstitutesList("Advertisement");
}
}

i send userid from login.java to next activity but in other activity it doesnt receive that userid first time.at first time it display null but at other places it show/print userid correctely
if i restart app userid will be perfect and app will work fine
i dont know why it is happen at first time
code in other activity
Intent iin = getIntent();
Bundle b = iin.getExtras();
if (b != null) {
u_id = (String) b.get("userid");//first time it shows null but after restart it get correct value
Log.v(TAG, "userlogged in" + u_id);
}
because you sending null first time change below in your onpost method
Intent i = new Intent(getApplicationContext(), UserLogedIn.class);
i.putExtra("user", shareduid);
Log.v(TAG, "" + userid);
startActivity(i);
in above shareduid is null first time you setting by shared preference so just put below
Intent i = new Intent(getApplicationContext(), UserLogedIn.class);
i.putExtra("user", userid);
Log.v(TAG, "" + userid);
startActivity(i);
check with this and let me know also i think check with key if you putextra with 'user' key you have to access with the same 'user' key
When I click on button in my program without entering data it shows both errors parallely (I have Highlighted in below prog). here i need to get only one error at a time i mean when it is null it has show appropriate one.vice versa..
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(v==findViewById(R.id.button1)) {
et1 = (EditText) findViewById(R.id.editText1);
if(et1.getText()!=null ) {
try {
radius = Double.valueOf(et1.getText().toString());
}
catch (Exception e) {
Toast.makeText(getApplicationContext(), "Please enter correct value", Toast.LENGTH_SHORT).show();
}
}
if(radius==0.0) {
Toast.makeText(getApplicationContext(), "Value cannot be 0", Toast.LENGTH_SHORT).show();
}
try {
output = (double) Math.round(Math.PI * radius * radius);
String s = Double.toString(output);
tv1.setText(s);
}
catch (Exception e) {
Toast.makeText(getApplicationContext(), "Please enter correct value", Toast.LENGTH_SHORT).show();
}
}
}
});
do not make things more complicated as they actually are. You can be sure that a correct value was entered without any try/catch blocks. Possible approach:
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
Pattern p = Pattern.compile("([0-9]*)");
if (et1.getText().toString().trim().length() > 0) {
Matcher m = p.matcher(et1.getText().toString().trim());
if (m.matches()) {
radius = Double.valueOf(et1.getText().toString());
output = (double) Math.round(Math.PI * radius
* radius);
tv1.setText(Double.toString(output));
} else
Toast.makeText(getApplicationContext(),
"incorrect value", Toast.LENGTH_SHORT)
.show();
} else
Toast.makeText(getApplicationContext(),
"input is empty", Toast.LENGTH_SHORT).show();
break;
default:
}
}
});
In the above code you check if there was any text entered. The second if checks whether the input is numeric using a java regex. When both requirements are met you can be sure the output is calculated correctly.
BTW, using switch-case is a better approach for click listeners
I am new to android. I want to show progress dialog when user click on login button. I tried this but the dialog is not showing
btn_logIn.setOnClickListener(new OnClickListener() {

}); //end of anonymous class

if (dialog == null) {

}
dialog.setMessage("Please Wait. Your authentication is in progress");
dialog.setButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which)
dialog.dismiss();
}
}); //end of anonymous class
dialog.show();
} //end of showProgressDialog()
private void getUserCredentials() {
EditText txt_userName = (EditText) findViewById(R.id.txt_userName);
String userName = txt_userName.getText().toString();
EditText txt_password = (EditText) findViewById(R.id.txt_password);
String password = txt_password.getText().toString();
if (userName != null && !userName.trim().equals("") && password != null && !password.trim().equals("")) {
showProgressDialog();
callWebService(userName, password);
}
} //end of getUserCredentials()

}
} //end of callWebServide()
Am i doing anything wrong. When i click on login button and service is not running then it shows message that Service is not connected, Please make sure your server is running", but the dialog isn't showing...Why? My logic is when user click on login button and fields have values then start showing progress dialog and if anything happens like when result come or server is not running or if any exception happen , then i remove the dialog and show the appropriate message, but dialog isn't showing...Why? What i am doing wrong? Please help..
Thanks
Try this,
Change your getUserCredentials() like this,
private void getUserCredentials() {
EditText txt_userName = (EditText) findViewById(R.id.txt_userName);
String userName = txt_userName.getText().toString();
EditText txt_password = (EditText) findViewById(R.id.txt_password);
String password = txt_password.getText().toString();
if (userName != null && !userName.trim().equals("") && password != null && !password.trim().equals("")) {
showProgressDialog();
Thread t=new Thread(new Runnable() {
public void run() {
callWebService(userName, password);
}
}); t.start();
}
}
And your callWebService method like this,
private void callWebService(String userName, String password) {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("userName", userName);
....
Object result = envelope.getResponse();
if (result.equals("true")) {
dialog.dismiss();
Toast.makeText(this, result.toString(), Toast.LENGTH_SHORT).show();
} else {
ActivityName.this.runOnUiThread(new Runnable() {
public void run() {
dialog.dismiss();
Toast.makeText(this, result.toString(), Toast.LENGTH_SHORT).show();
}
});
}
} catch (SocketTimeoutException e) {
ActivityName.this.runOnUiThread(new Runnable() {
public void run() {
dialog.dismiss();
Toast.makeText(this, "Service is not connected, Please make sure your server is running", Toast.LENGTH_LONG).show();
}
});
} catch(Exception e) {
e.printStackTrace();
ActivityName.this.runOnUiThread(new Runnable() {
public void run() {
dialog.dismiss();
Toast.makeText(this, "Unable to connect, please try again later. Thank you", Toast.LENGTH_LONG).show();
}
});
}
}
Update 1
To answer your questions from your comments,
1)Yes Async Task is more efficient. It has its own methods to do the same task what I have described here.
AsyncTask has the following methods,
i)onPreExecute()-which can be used to start your Dialog
ii)doInBackground()-which acts as the background thread.
iii)onPostExecute()-which gets called at the end where you can dismiss the dialog.
The reason why I didn't mention is that, there are possibilities that you might have to change your working code's structure to adapt to Async task.
2)runonUiThread- as the name indicates, anything inside this will be considered as it is running in the main UI thread. So basically to update the screen you have to use this. There are also other methods available, like Handlers which can also do the same task.
Use AsyncTask for it when ever task started at that time initialise your widget and then call your webservice from run method and close your progress bar on stop method.
I have a activity am using a boolean condition to check some thing .if the boolean condition Satisfy i need to Go to The next Page. But When The condition Satisfy the Device get crash With NullPointerException Am giving The Code Below
The Boolean Condition
boolean check()
{
boolean matches=false;
int falseFlag=0;
if(cc.length==picarray.length)
{
for (int i=0;i<cc.length;i++)
{
if(cc[i].equals(picarray[i]))
{
//---The Database Value Stored in Array is modified---
xmin=X[i]-25;
xmax=X[i]+25;
ymin=Y[i]-25;
ymax=Y[i]+25;
//---Check Whether The Selected Password Is Inside The Array Values---
if(xmin<realx[i]&&realx[i]<xmax)
{
System.out.println("TRUE");
}
else
{
falseFlag++;
System.out.println("FALSE");
}
if(ymin<realy[i]&&realy[i]<ymax)
{
System.out.println("TRUE");
}
else
{
falseFlag++;
System.out.println("FALSE");
}
}
else
{
falseFlag++;
}
}
}
else
{
falseFlag++;
}
if(falseFlag==0)
{
matches=true;
}
System.out.println("Authentication returns "+matches);
return matches;
}
in button click
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(check())
{
Intent sa=new Intent(Test.class,Test2.class);
startActivity(sa);
System.out.println("U R AUTHENTICATED");
}
else
{
System.out.println("INVALID USER");
Toast.makeText(getApplicationContext(), "INVALID USER", Toast.LENGTH_LONG).show();
}
}
});
try this,
Intent sa=new Intent(getApplicationContext(),Test2.class);
basically intent needs context and not a class...
i doub't this (Intent sa=new Intent(Test.class,Test2.class);) will compile
The first argument is a Context so when you create the intent, it should be:
Intent sa=new Intent(Test.this,Test2.class);
instead of
Intent sa=new Intent(Test.class,Test2.class);
This should also work:
Intent sa=new Intent(v.getContext(),Test2.class);
Intent sa=new Intent(Test.class,Test2.class);
The first parameter should be Test.this(Context), is it not throwing a Compile-time error ??
