Parsing user input in edittext field of the type date and check for correct date format

I am working on an Android app and processing user input from an edittext field. I want to check if the user entered a correct date format; however, for reasons that I don´t understand, I need to convert the type of the edittext type date to a string and then convert it back to a float number, to check against a regular expression and that is not working correctly.
The editactivity.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Actually, why do I need to read the input in an input type of date, cast it to an integer and check if this integer value has the right format? Isn`t there any other, better way? I just want to check that the users does not enter more than 6 digits and that these digits have the right format.
Any hints or help would be appreciated, thanks!

I just want to check that the users does not enter more than 6 digits and that these digits have the right format.
Lets say, required format is dd-mm-yy
Use regex - \d{2}-\d{2}-\d{2}
For example,
if (inputSTR.matches("\\d{2}-\\d{2}-\\d{2}")) {
// input matches to required pattern
} else {
// Show error msg
}

First, Tim Biegeleisen’s comment that you should use a date picker rather than an EditText is probably well worth considering.
Anyway, if you get your date as a string, the recommended way of validating it is to try to parse it into a date and see if you succeed — not through a regular expression. And you certainly shouldn’t try to parse it as an integer, that is bound to fail. My code would go something like:
String ss = date.getText().toString();
if (ss.isEmpty()) {
// tell the user to enter something
} else {
try {
LocalDate.parse(ss);
// tell the user the format is right
} catch (DateTimeParseException dtpe) {
// tell the user that this is not a valid date
}
}
I am assuming that your date should be in the format yyyy-MM-dd. This is the default parse format for LocalDate, so it’s rather straightforward if you know about exceptions and try/catch constructs. If you require a different format, you will need to specify it through a DateTimeFormatter.
The advantage over the regex approach is it gives you much better validation. ^\\d{4}-\\d{2}-\\d{2}$ will accept 2017-29-11 and 2017-11-92 as dates, where the parsing approach will catch if the month is not 1 through 12 or the day-of-month is not within the number of days in that month.
Now you are at it, if you need to keep your date (likely since you asked the user to enter it), keep it as a LocalDate object rather than a string. This will prepare your app for doing all sorts of operations on the date. Whenever you need a string, just use LocalDate.toString(). Or use a DateTimeFormatter if you want the string as for example “Sunday November 19, 2017” or even in German or some other language.
I am using java.time, the modern Java date and time API also known as JSR-310. Unfortunately this doesn’t come with most Android devices yet. The solution is the ThreeTenABP, the backport of JSR-310 to Android. I encourage you to get this and start coding.

EditText cursor visible even if the EditText is not editable

I need to introduce data in an EditText but i want to use an virtual keyboard, not the android keyboard. If I use setKeyListener(null) the cursor is invisible even after using setCursorVisible(true).
Is it possible to make an EditText where even if it isn't editable the cursor is visible ?
EDIT 2 :
I found an partial method to do that, but it's not working when i'm double taping the EditText.
I made an setOnClickListner() and an setOnLongClickListner() method for the EditText. In this methods I hide the Soft Input from the Window, also i use setTextIsSelectable(false). My only problem is that when I double tap the EditText the soft input keyboard shows and I dont know how to hide it, I tried to use android:windowSoftInputMode="stateAlwaysHidden" in manifest, but it doesn't work either.
EDIT :
Here is the code that I'm using at this moment for my base converter calculator.
public class MainActivity extends AppCompatActivity {
EditText number;
EditText base;
boolean baseB = false;
String numberS = "0";
String baseS = "10";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_main);
//make the EditText for number and base not editable
number = (EditText) findViewById(R.id.number);
number.setKeyListener(null);
base = (EditText) findViewById(R.id.base);
base.setKeyListener(null);
//... more code here (changing fonts for each EditText and changing status bar color
}
// I have a function for each button all are the same
public void onClickBaseChange(View v) {
if (baseB) {
baseB = false;
// i use toasts at this moment to know when i'm on number or base field
Toast.makeText(this, "Number", Toast.LENGTH_SHORT).show();
} else {
baseB = true;
Toast.makeText(this, "Base", Toast.LENGTH_SHORT).show();
}
}
public void onClickB0(View v) {
if (numberS.length() > 0 && !numberS.equals("0") && !baseB) {
numberS += "0";
number = (EditText) findViewById(R.id.number);
number.setText(numberS, TextView.BufferType.EDITABLE);
number.setSelection(numberS.length());
} else {
if (Integer.valueOf(baseS) >= 1) {
baseS += "0";
base = (EditText) findViewById(R.id.base);
base.setText(baseS, TextView.BufferType.EDITABLE);
}
}
}
public void onClickB1(View v) {
if (numberS.equals("0")) {
numberS = "1";
} else {
numberS += "1";
}
number = (EditText) findViewById(R.id.number);
number.setText(numberS, TextView.BufferType.EDITABLE);
number.requestFocus();
number.setSelection(numberS.length());
}

In your xml you can give like this,
<[package name].KeypadlessKeypad
android:id="#+id/dialnumbertv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#00000000"
android:cursorVisible="false"
android:ellipsize="start"
android:gravity="center"
android:inputType="phone"
android:singleLine="true"
android:textIsSelectable="true"
android:textSize="30sp"
android:textStyle="italic"
android:visibility="visible"/>
And in your fragment you can implement like this,
public void onViewCreated(final View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mDialNumbertv = view.findViewById(R.id.dialnumbertv);
mDialNumbertv.setCursorVisible(false);
mDialNumbertv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!isDigitsEmpty()) {
mDialNumbertv.setCursorVisible(true);
}
}
});
mDialNumbertv.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
if (isDigitsEmpty()) {
mDialNumbertv.setCursorVisible(false);
}
// updateDeleteButton();
}
});
mDialNumbertv.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
// Ref https://android.googlesource.com/platform/packages/apps/Contacts/+/39948dc7e34dc2041b801058dada28fedb80c388/src/com/android/contacts/dialpad/DialpadFragment.java
// Right now EditText does not show the "paste" option when cursor is not visible.
// To show that, make the cursor visible, and return false, letting the EditText
// show the option by itself.
mDialNumbertv.setCursorVisible(true);
return false;
}
});
mDialNumbertv.setOnEditTextActionListener(
new KeypadlessKeypad.OnEditTextActionListener() {
#Override
public void onPaste() {
// If some content pasted on mDialNumbertv
// we need to run some search on Contact and Price
String mobileNumber = mDialNumbertv.getText().toString();
if (TextUtils.isEmpty(mobileNumber)) {
return;
}
// updateContactName(mobileNumber);
}
});
}
private KeypadlessKeypad mDialNumbertv;
private boolean isDigitsEmpty() {
return mDialNumbertv.length() == 0;
}
private void setClickedDigit(final String digitToSet) {
if (!TextUtils.isEmpty(digitToSet)) {
char digit = digitToSet.charAt(0);
String mobileNumber = mDialNumbertv.getText() + digitToSet;
mDialNumbertv.getText().insert(mDialNumbertv.getSelectionStart(), digitToSet);
// If the cursor is at the end of the text we hide it.
final int length = mDialNumbertv.length();
if (length == mDialNumbertv.getSelectionStart() && length == mDialNumbertv.getSelectionEnd()) {
mDialNumbertv.setCursorVisible(false);
}
}
}

I wanted the same behavior which I achieved as follows -
Make a custom class that will override 2 methods of AppCompatEditText.
class CustomEditText(context: Context?, attrs: AttributeSet) : AppCompatEditText(context, attrs) {
override fun onCheckIsTextEditor(): Boolean {
return true
}
override fun isTextSelectable(): Boolean {
return true
}
}
In the XML file, create EditText using this custom view.
<com.ui.custom.CustomEditText
android:id="#+id/et_email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="none"
android:focusable="true"
android:gravity="center"
android:focusableInTouchMode="true"/>
Now, just add onFocusChangeListener and set editText.setKeyListener = null.
binding.etEmail.onFocusChangeListener = OnFocusChangeListener { v, hasFocus ->
if (hasFocus) {
binding.etEmail.keyListener = null
}
}
You can add the same on onTouch if that is the requirement.
The main issue here is that onCheckIsTextEditor() of View class always returns false, which leads to cursor never blinking or being visible even if setCursorVisible(true) was called in code.
I hope it helps.

You can use edittext.setselection(0)
or
maybe you can request focus using requestfocus()

Android app - Inputting integers from buttons depending on number of presses

I'm writing a calculator app for android using android studio. I want to used 4 buttons for inputting values and functions. However the way I am currently doing it takes the input from the text written on the button. So for my button 1/2/3 when this is pressed 1/2/3 is passed to the textView.
Below is my MainActivity:
package com.example.myfirstapp;
import android.media.MediaPlayer;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.MediaController;
import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
private int[] operatorButtons = {R.id.operators};
private int[] numericButtons = {R.id.onetwothree, R.id.fourfivesix, R.id.seveneightninezero};
private boolean lastNumeric, stateError;
private TextView txtScreen;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Find the TextView
this.txtScreen = (TextView) findViewById(R.id.txtScreen);
// Find and set OnClickListener to numeric buttons
setNumericOnClickListener();
// Find and set OnClickListener to operator buttons, equal button and decimal point button
setOperatorOnClickListener();
}
private void setNumericOnClickListener() {
// Create a common OnClickListener
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
// Just append/set the text of clicked button
Button button = (Button) v;
if (stateError) {
// If current state is Error, replace the error message
txtScreen.setText(button.getText());
stateError = false;
} else {
// If not, already there is a valid expression so append to it
txtScreen.append(button.getText());
}
// Set the flag
lastNumeric = true;
}
};
// Assign the listener to all the numeric buttons
for (int id : numericButtons) {
findViewById(id).setOnClickListener(listener);
}
}
private void setOperatorOnClickListener() {
// Create a common OnClickListener for operators
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
// If the current state is Error do not append the operator
// If the last input is number only, append the operator
if (lastNumeric && !stateError) {
Button button = (Button) v;
txtScreen.append(button.getText());
lastNumeric = false;
}
}
};
// Assign the listener to all the operator buttons
for (int id : operatorButtons) {
findViewById(id).setOnClickListener(listener);
}
// Equal button
/*findViewById(R.id.btnEqual).setOnClickListener(new View.OnClickListener() {

Will it be possible for me to get the input of 1, 2 or 3 from my first button for example? So on 1 press you get 1, 2 press gives 2 etc.
Any suggestions/ ideas on how I can move forward with this are greatly appreciated.
Kind Regards,
Ben

You could use a timer or delay variable to detect single, double or triple taps. This post may be of interest. If the time interval is not a factor, you could just keep track of the last pressed button and if the same button is being pressed again, update the text accordingly.
If you follow approach one, the code for the click listener for button onetwothree may be something like this (I commented out setNumericOnClickListener() and setOperatorOnClickListener(); in mainActivity onCreate and added the following):
Button onetwothree = (Button) findViewById(R.id.onetwothree);
onetwothree.setOnTouchListener(new View.OnTouchListener() {
Handler handler = new Handler();
int numberOfTaps = 0;
long lastTapTimeMs = 0;
long touchDownMs = 0;
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
touchDownMs = System.currentTimeMillis();
break;
case MotionEvent.ACTION_UP:
handler.removeCallbacksAndMessages(null);
if ((System.currentTimeMillis() - touchDownMs) > ViewConfiguration.getTapTimeout()) {
//it was not a tap
numberOfTaps = 0;
lastTapTimeMs = 0;
break;
}
if (numberOfTaps > 0
&& (System.currentTimeMillis() - lastTapTimeMs) < ViewConfiguration.getDoubleTapTimeout()) {
numberOfTaps += 1;
} else {
numberOfTaps = 1;
}
lastTapTimeMs = System.currentTimeMillis();
if (numberOfTaps == 1) {
handler.postDelayed(new Runnable() {
#Override
public void run() {
if (txtScreen.getText().toString() == "") {
txtScreen.setText("1");
} else txtScreen.append("1");
}
}, ViewConfiguration.getDoubleTapTimeout());
}else if (numberOfTaps == 2) {
handler.postDelayed(new Runnable() {
#Override
public void run() {
if (txtScreen.getText().toString() == "") {
txtScreen.setText("2");
} else txtScreen.append("2");
}
}, ViewConfiguration.getDoubleTapTimeout());
} else if (numberOfTaps == 3) {
if (txtScreen.getText().toString() == "") {
txtScreen.setText("3");
} else txtScreen.append("3");
}
}
return true;
}
});

You can take all numbers when doing some operation
(Button) plusBtn = (Button) findViewById(R.id.plusBtn);
plusBtn.setOnClickListener(new OnClickListener(){
#Override
public voidonClick(View v){
number1 = Integer.parseInt(txtScreen.getText().toString());
});
Where number1 is global int. But I don't know how it can help you and if it is a good approach. You could find a better solution, just remember how to parse the String from your TextView to Integer for your calculation.

how to know the check box value of a particular row of a listview

hey how can i know that the below checkbox when clicked is from which row of the list.
is there any way of knowing that. Every time yo is returning false which is its default value.
checkBox.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v ;
callBlockOptions callBlockOptions = (callBlockOptions) cb.getTag();
callBlockOptions.setChecked( cb.isChecked() );
String yo;
if(callBlockOptions.getPosition()=="0")
{
callBlockOptions.setAllCalls();
}
if(callBlockOptions.getAllCalls() ==true)
yo="true";
else
yo="false";
Toast.makeText(getContext(), callBlockOptions.getPosition(), Toast.LENGTH_LONG).show();
}
});
}

After seeing your code, one thing you might want to try is setting listeners for the individual children within the ListView. You could do something like this:
ListView listView = (ListView)findViewById(R.id.listView);
int count = listView.getChildCount();
for (int x = 0; x < count; x++)
{
Class<? extends View> c = listView.getChildAt(x).getClass();
if (c == CheckBox.class)
{
CheckBox checkBox = (CheckBox)(listView.getChildAt(x));
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener(){
#Override
public void onCheckedChanged(CompoundButton compoutButton, boolean isChecked) {
// TODO Auto-generated method stub
callBlockOptions.isChecked = isChecked;
}
});
}
else if (c == TextView.class)
{
TextView textView = (TextView)(listView.getChildAt(x));
textView.setOnEditorActionListener(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView tView, int arg1, KeyEvent arg2) {
// TODO Auto-generated method stub
callBlockOptions.name = tView.getText().toString();
return true;
}
});
}
You probably want your other class to be like this:
public class callBlockOptions {
public static String name;
public static Boolean isChecked;
}
Then you can get and set name and isChecked like this:
callBlockOptions.isChecked = false;
Boolean boolVal = callBlockOptions.isChecked;

EditText array FocusChange

I have 80 EditText fields (cube[i]) and want to read what is in inside the text fields when the text field loses focus.
I can detect when any of the EditTexts (cube) loses focus but I cannot detect exactly which one, Im trying to find which cube is focused on.
the line "EditText cube = (EditText) v.getClass();" is giving me an error
Maybe I can use the View v?
for (int i = 0; i < cube.length; i++) {
cube[i].setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
EditText cube = (EditText) v.getClass();
String s = cube.getText().toString();
//cubecolor();
}
}
});
}
}
Any help is appreciated.

while creating set some tag to the editText like this (pseudo code)
EditText edit = new EditText(context);
edit.setTag(Integer.valueOf(i)); // i is within the for loop;
Now during the onFocus get the tag
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
EditText cube = (EditText) v;
Integer tag = (Integer)cube.getTag();
//code to sort out which cube based on tag
String s = cube.getText().toString();
//cubecolor();
}
}

This worked, Thanks Dante.
for (int i = 0; i < cube.length; i++) {
cube[i].setTag(Integer.valueOf(i)); // give cubes tags
}
for (int i = 0; i < cube.length; i++) {
cube[i].setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
Integer tag = (Integer) v.getTag();
String s = cube[tag].getText().toString();
Log(TAG, " Content" + s);
revert_cubecolor(tag);
}
}
});
}
