LayoutInflater inflater = getActivity().getLayoutInflater();
View layout = inflater.inflate(R.layout.dialog_set_mobile,(ViewGroup) view.findViewById(R.id.dialog_mobile));
new AlertDialog.Builder(getActivity()).setTitle("Please Input Contact Information").setIcon(
android.R.drawable.ic_dialog_dialer).setView(

}
This is my button code
mButtonCheckout = (Button) view.findViewById(R.id.checkout_pay);

you have two way
1 : Instead on mobile use this
Toast.makeText(getContext(),inputMobile.getText().toString(), Toast.LENGTH_SHORT).show();
2 : Create global string variable mobile like this
first create global mobile number above on onCreateView()
public String mobileNumber;
then in you button click in dialog init mobileNumber
try{
long number = Long.valueOf(inputMobile.getText().toString());
SPManipulation.getInstance(getActivity()).setMobile(inputMobile.getText().toString());
mTextMobile.setText(inputMobile.getText().toString());
FirebaseAuth mAuth = FirebaseAuth.getInstance();
String userID = mAuth.getCurrentUser().getUid();
mobileNumber = inputMobile.getText().toString();//THIS LINE CHANGED
DatabaseReference mynum = database.getReference().child(userID).child("number");
mynum.setValue(mobile);
}catch (Exception e){
Toast.makeText(getActivity(), "Please Input Correct Phone Number!", Toast.LENGTH_SHORT).show();
}
Now you can use mobileNumber anywhere like in button
mButtonCheckout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getContext(),mobileNumber, Toast.LENGTH_SHORT).show();
}
});

declare a String variable to store the value of the EditText
String mobileNumber = inputMobile.getText().toString();
Create your Toast inside the OnClickListener.
Toast.makeText(getContext, mobileNumber,Toast.LENGTH_LONG).show();

How check my edit text input value is equals to the array value

I want to check whether my edit text value is equal to the array value
String[] zipcode = {"123","456"} toast success if match else failed.
Here is my code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText et_zipcode = (EditText) findViewById(R.id.etzipcode);
Button bt_submit = (Button) findViewById(R.id.btsave);
bt_submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String[] zipcodes = {"123","456"};
if (et_zipcode.getText().equals(zipcodes)){
Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
}else {
Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
}
}
});
}
}

Try this code it might help you
String edittext = et_zipcode.getText();
for(int i = 0; i<zipcodes.size(); i++){
if(edittext .equals(zipcodes.get(i).toString)){
Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
}
}

Use this condition for checking if edit text contains zip codes:
if(Arrays.asList(zip).contains(et_zipcode.getText().toString()))

button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean isSuccess = true;
String[] zipcodes = {"123", "456"};
for (int i = 0; i < zipcodes.length; i++) {
if (et_zipcode.getText().toString().equals(zipcodes[i])) {
isSuccess = false;
Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
}
}
if (isSuccess) {
Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
}
}
});

String[] zipcodes = {"123","456"};
boolean contains = Arrays.asList(zipcodes ).contains(et_zipcode.getText());
if (contains)
{Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();}
else {Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();}

**try this one**
bt_submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String[] zipcodes = {"123","456"};
String entertext = et_zipcode.getText().toString();
boolean result= Arrays.asList(zipcodes).contains(entertext);
System.out.println(result);
if(result==true ){
System.out.println("matched");
}else {
System.out.println(" not matched"); }
}
});
}

getText().toString() not working, returns empty

I'm trying to save userName but the saved text file always returns , 6. How can I get it to show whatever value of userName entered into EditText, and the rest? for example Don, 6. I have read you have to use getText() but that isn't returning anything in the saved file.
However, if I replace 6 with an intent to receive score from previous activity, this works! like this...
Bundle extras = getIntent().getExtras();
int score = extras.getInt("Score");
So this becomes...
public void addListenerToEndButton() {
quit = (Button) findViewById(R.id.endBtn);
userName = (EditText) findViewById(R.id.userName);
Bundle extras = getIntent().getExtras();
int score = extras.getInt("score");
quit.setOnClickListener(new View.OnClickListener() {
String strName = userName.getText().toString();
#Override
public void onClick(View v) {
saveProgress(strName + ", " + score, "results.txt");
finish();
System.exit(0);
}
});
}
But it still returns empty, whatever score is. For example , 4.
I've read this post that suggests it should be inside onClickListener which it is:
EditText getText().toString() not working
This is my saveProgress class:
public void saveProgress(String contents, String fileName) {
try {
File fp = new File(this.getFilesDir(), fileName);
FileWriter out = new FileWriter(fp);
out.append(contents);
out.append("\n\r");
out.close();
}
catch (IOException e) {
Log.d("Me","file error:" + e);
}
}

Change your onClick() method with the following:
public void addListenerToEndButton() {
quit = (Button) findViewById(R.id.endBtn);
userName = (EditText) findViewById(R.id.userName);
Bundle extras = getIntent().getExtras();
int score = extras.getInt("score");
quit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String strName = userName.getText().toString();
saveProgress(strName + ", " + score, "results.txt");
finish();
System.exit(0);
}
});
}
Calls, initializations, operations, exc, should go inside the onClick method of the listener. The onClick is fired only when the button is clicked, everything outside the onClick but inside the Listener is called on Listener initialization

I guess you understood 'inside onClickListener' wrong. What you are doing atm is that you read strName when you create the listener, but I guess you want to read it when quit is clicked.
So just move the line into the function and the value will be correct.
public void addListenerToEndButton() {
quit = (Button) findViewById(R.id.endBtn);
userName = (EditText) findViewById(R.id.userName);
quit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String strName = userName.getText().toString();
saveProgress(strName + ", " + 6, "results.txt");
finish();
System.exit(0);
}
});
}

Unable to hide button from Listview in Custom Dialog Android

In first activity i have button(Named btIndividual) inside listview from that one custom dialog layout opens. In that custom dialog i have one text and edittext field inside listview and one save Button for posting data to server. Now i want that after posting data to server the button named btIndividual in first activity will go invisible.
Custom Adapter for first activity:
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ProductChoosed productChoosed = productChoosedAr.get(position);
convertView = View.inflate(SolutionActivity.this, R.layout.custom_solution_row, null);
ImageView categoryImageView = (ImageView) convertView.findViewById(R.id.categoryImageView);
TextView categoryNameTextView = (TextView) convertView.findViewById(R.id.categoryNameTextView);
productsListTextView = (TextView) convertView.findViewById(R.id.productsListTextView);
btIndividual = (Button) convertView.findViewById(R.id.btIndividual);
String catgoryImage = "";
String isTradeProduct = productChoosed.isTradeProduct;
if(isTradeProduct.equals("0")){
btIndividual.setVisibility(View.VISIBLE);
productsListTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showTradDialog(position, productChoosedAr.get(position));
}
});
}else{
btIndividual.setVisibility(View.GONE);
}
btIndividual.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showIndividualTradDialog(position,productChoosedAr.get(position));
individual_productChoosedAr.clear();
myList.clear();
idIndividual = "";
mIndCount =1;
checkHideButton = position ;
checkButtonPosition = position;
idIndividual = productChoosedAr.get(position).categoryId;
GetIndividualProducts getIndividualProducts = new GetIndividualProducts();
getIndividualProducts.execute();
showDialog();
Toast toast = Toast.makeText(getApplicationContext(),"Loading...",Toast.LENGTH_LONG);
toast.show();
}
});
Custom Dialog layout :
private void showDialog(){
dialog1 = new Dialog(this);
final Dialog tradDialog = new Dialog(this, android.R.style.Theme_Light_NoTitleBar);
View view = getLayoutInflater().inflate(R.layout.trad_dialog_layout_individual, null);
tradDialog.setCanceledOnTouchOutside(false);
lv = (ListView) view.findViewById(R.id.productsListView);
RelativeLayout saveBtnLayout = (RelativeLayout) view.findViewById(R.id.saveBtnLayout);
// Change MyActivity.this and myListOfItems to your own values
clad = new CustomListAdapterDialog(SolutionActivity.this, individual_productChoosedAr);
lv.setAdapter(clad);
clad.notifyDataSetChanged();
mCount = lv.getChildCount();
saveBtnLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int getChildCount1 = lv.getChildCount();
System.out.print(getChildCount1);
for (int i = 0; i < myList.size(); i++) {
// v = lv.getChildAt(i);
// etPrice = (EditText) v.findViewById(R.id.etPrice);
if(myList.get(i).toString().equals("")){
ProductPrice = "NULL";
}else {
ProductPrice = myList.get(i).toString();
}
// if(ProductPrice.equals("")){
// ProductPrice = "NULL";
// }
productPriceAr.add(ProductPrice);
}
Toast toast = Toast.makeText(getApplicationContext(),"Please wait...",Toast.LENGTH_LONG);
toast.show();
SendIndividualDatatoServer sendIndividualData = new SendIndividualDatatoServer();
sendIndividualData.execute();
}
});
//lv.setOnItemClickListener(........);
dialog1.setContentView(view);
dialog1.show();
}
AsyncTask class for posting data from where i want to disable btIndividual button:
protected void onPostExecute(Void paramVoid) {
super.onPostExecute(paramVoid);
try {
String typeId = "", messageReceived = "";
JSONObject localJSONObject = new JSONObject(this.sendDataResponse);
typeId = localJSONObject.getString("type_id");
messageReceived = localJSONObject.getString("msg");
if (typeId.equals("1")) {
//if i reached here i want to disable that button
// if(checkHideButton == checkButtonPosition){
// btIndividual.setVisibility(View.GONE);
// customSelectedProductsAdapter.notifyDataSetChanged();
// customSelectedProductsAdapter.notifyDataSetInvalidated();
// }
Toast toast = Toast.makeText(SolutionActivity.this,"Individual Data Posted",Toast.LENGTH_LONG);
toast.show();
dialog1.dismiss();
customSelectedProductsAdapter.notifyDataSetChanged();
productPriceAr.clear();
individual_productChoosedAr.clear();
} else
Toast.makeText(SolutionActivity.this, messageReceived, Toast.LENGTH_SHORT).show();
btIndividual.setVisibility(View.VISIBLE);
} catch (Exception localException) {
localException.printStackTrace();
Toast.makeText(SolutionActivity.this, "Network Error Occured", Toast.LENGTH_SHORT).show();
}

I guess the problem is here:
} else
Toast.makeText(SolutionActivity.this, messageReceived, Toast.LENGTH_SHORT).show();
btIndividual.setVisibility(View.VISIBLE);
You set the button visible even if your condition below is true.
I suggest to modify the code something like this:
protected void onPostExecute(Void paramVoid) {
super.onPostExecute(paramVoid);
try {
//1. By default button is visible
btIndividual.setVisibility(View.VISIBLE);
String typeId = "", messageReceived = "";
JSONObject localJSONObject = new JSONObject(this.sendDataResponse);
typeId = localJSONObject.getString("type_id");
messageReceived = localJSONObject.getString("msg");
if (typeId.equals("1")) {
if(checkHideButton == checkButtonPosition){
//2. if condition is true - hide the button
btIndividual.setVisibility(View.GONE);
customSelectedProductsAdapter.notifyDataSetChanged();
customSelectedProductsAdapter.notifyDataSetInvalidated();
}
Toast toast = Toast.makeText(SolutionActivity.this,"Individual Data Posted",Toast.LENGTH_LONG);
toast.show();
dialog1.dismiss();
customSelectedProductsAdapter.notifyDataSetChanged();
productPriceAr.clear();
individual_productChoosedAr.clear();
} else
Toast.makeText(SolutionActivity.this, messageReceived, Toast.LENGTH_SHORT).show();
//3. it is not needed
//btIndividual.setVisibility(View.VISIBLE);
} catch (Exception localException) {
localException.printStackTrace();
Toast.makeText(SolutionActivity.this, "Network Error Occured", Toast.LENGTH_SHORT).show();
}

Your code is right, only missing this is { } braces in the else condition, try out as following,
if (tpeapinemptycheck.trim().equals("")||
(otheraccountemptycheck.trim().equals("")) ||(amountemptycheck.trim().equals("")))
{
Toast.makeText(getApplicationContext(), "Please Enter
Correct Information", Toast.LENGTH_LONG).show();
}
else
{ // add this
showProgress();
submitPEA();
} // add this
Just because you haven't added those { } braces, your control was going into submitPEA() method.

Try like this
edit_text.getText().toString().trim().equals("");

Create a String variable say x;
Now if et is your EditText field use this:
x = et.getText().toString();
if the EditText field has any text in it it would be passed to the string x.
Now to check if the string x is not null or contains nothing use
if(x.matches(""))
{
//your code here
}
else
{
//the counter action you'll take
}
this way you can check that the entry you are about to enter in the database won't be empty.
Happy coding.
