I have an application where user inputs text into EditText field. After user clicks OK (in keyboard input mode), a correct value is in the EditText (lets say "Smile").
if (answers.get(counter).getText().equals(opponentAnswers.get(counter)))
But this if statement fails, because the same EditText has the values that were suggested by T9 option, when user was inputing his answer (for example values of EditText would be "Smile Smiling Smiled"), while it should only have a value "Smile".
Any ideas how to solve this issue?
That's really weird. These are kind of guesses, but this is what I'd try next if I were you:
A. Instead of doing an equals against getText(), try doing a toString on getText(), so:
if (answers.get(counter).getText().toString().equals(opponentAnswers.get(counter)))
B. If that doesn't work then you could try adding a TextWatcher using addTextChangedListener on the EditText, and getting the value from that. Calling toString() on the editable returned in afterTextChanged might give you the value you want.
private class SearchTextWatcher implements 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) {
//Get the text the user sees
String textShownToUser = s.toString();
}
}
Hope this helps! Best of luck!

I have a simple EditText, which inputs only numbers.
I want to show 0(zero) even if user presses backspace.
Now zero is getting deleted.
Moreover, I need to remove this default zero, when user starts entering values.
How do i achieve it?
You should use android:hint="0" or in more complex way..
You should use TextWatcher and override the below three methods. THer you can get the text in the arguments as CharSequence in the beforeTextChanged and onTextChanged methods and in afterTextChanged you have Editable from where you can get the data in the EditText. Write in the desired function as per your logic and it should work like a charm.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(final CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
}
});
It sounds like you want:
<EditText
android:hint="0" />
Hi I am learning Android programming and have run into an issue that I couldn't get a clear answer to through researching.
I have a TextView which serves as a label for my EditText. I have a method which checks if the EditText is an empty String. If the string is empty I want to be able to get a reference to the TextView that corresponds to that EditText in order to make a toast saying something like "please enter a value for ".
I've looked into getLabelFor/setLabelFor but is there a way to do this in the layout XML?
What is best practice for this type of functionality.
You're describing a functionally that is build in to EditText. There is a special field you can define in xml called hint, which is the recommended way to label an EditText rather than a nearby TextView. Additionally, EditText has a method called setError() (link). If the user attempts to hit a submit button, for example, you can check to see if the EditText is empty and if so, call setError().
I wonder if the following is the thing that you need
TextWatcher inputTextWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after){
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (s.toString().equals("")) {
textView.setText("please enter a value for ..");
} else {
textView.setText("<the textedit is not empty>");
}
}
public void afterTextChanged(Editable s) {
}
};
editText.addTextChangedListener(inputTextWatcher);
I have 3 widgets on my screen, Text View, Edit Text and a Button. What ever I insert in my edit text, when I click the button, the text view gets the string from the edit text. Now, what I want to do is that, if I have already inserted the character "\" or "," or what ever character I want, it will not be inputted anymore. It's like, you can only put that character once in the edit text. Do you guys have any idea about it?
Well what I am thinking is that, I have to search from the edit view then validate it. But I don't know what code to use. Could somebody please help me? Thank you!
Use Android TextWatcher on EditText.
There are delegates which returns the charsequence that is entered
onTextChanged
afterTextChanged
beforeTextChanged
Fill the entered character in set everytime. If size is not incrementing that means a duplicate.
then avoid adding of that character in edittext
I think you need to add a TextChangedListener to your editText.
et.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void afterTextChanged(Editable s) {
}
});
I need to control pressed buttons, before they goes to my EditText widget. It's should work like filter.
For example: I need that user could fill EditText only with digits 1,2,3,4,5 other symbols must be ignored. So the part of buttons on virtual keyboard should be disabled or I need to catch last pressed symbol, analyze it and disable for EditText.
Who knows the way how to solve this problem?
Thanks..
statusEdt.addTextChangedListener(new TextWatcher(){
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {
//do stuff
charTxt.setText(statusEdt.getText().length() + "/140");
}
});
I used this TextChangedListener(TextWatcher) to keep a count of how many characters had been typed into an EditText for a Twitter client I made. You could probably use a listener like this. You'll want to override beforeTextChanged or onTextChanged. These methods will pass you whatever CharSequence has been typed. You can check what was typed in and if it is not valid input you can remove it by calling setText() and passing in whatever has been typed so far minus the invalid characters.
What you probably need is an InputFilter.
For example to allow only digits, sign and decimal point:
editText.setFilters(DigistKeyListener.getInstance(true, true));
I have three editboxes which has retrict to enter only one numeric digit on each box.when i enter the value of first box the focus should be moved from 1st box to 2nd.After entering value to 2nd box.,its focus should automatically moved to 2nd to 3rd like that i need to do.Could anybody help me regarding this?
You can use requestFocus() API to shift the focus from the code,
Keep listening for the text, using textWatcher, once specified limit is reached, call EditTextreference.requestFocus() to shift the focus.
This code moves focus from one EditText to another when EditText length greater than 1.
EditText et1,et2;
et1 = (EditText)findViewById(R.id.id1);
et2 = (EditText)findViewById(R.id.id2);
et1.addTextChangedListener(new TextWatcher()
{
public void afterTextChanged(Editable s)
{
// Abstract Method of TextWatcher Interface.
}
public void beforeTextChanged(CharSequence s,
int start, int count, int after)
{
// Abstract Method of TextWatcher Interface.
}
public void onTextChanged(CharSequence s,
int start, int before, int count)
{
Integer textlength = et1.getText().length();
if(textlength>=1){ //If text length greater than 1 move to next EditText
et2.requestFocus();
}
}
});
