How to disable a button for the user, until editText is active?

I want to make it impossible for the user to click on a button until he does not 'get out of' or clicks away from an EditText.
Like, the button will be there, but when the user goes to enter text in an EditText, it will be grayed out, and will be clickable again only when the user leaves the editText.
I hope my question is clear. How can I do this?

Your button behaviour depends on the focus of the editext so you can use
mEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
mButton.setEnabled(false)
} else {
mButton.setEnabled(true)
}
}
});
the if is extended, consider that you can solve in just one line
mButton.setEnabled(!hasFocus)

Set OnFocusChangeListener on your EditText:
editView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
button.setEnabled(!hasFocus);
}
});

Use setOnFocusChangeListener and override the onFocusChange. Then, use the button.setEnabled

EditText onFocus doesn't work properly

I have an EditText which I adjust the position on screen of when the user clicks it (when it gains focus). However, the method is not working properly. My code:
etHashtag.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
Log.d("EditText", "has focus");
originalHashtagPos = etHashtag.getY();
etHashtag.setY(targetH / 2);
}else {
Log.d("EditText", "no focus");
etHashtag.setY(originalHashtagPos);
}
}
});
The log shows that the focus is gained when the user clicks the EditText, and it loses focus when the user clicks outside the view. However, the Y position is not moved everytime. It only works in about 50% of the times. Thought this would be simple?

Simple edit text?

I am getting the users information from an edit text. I do have a listener that gets their entered information after clicking submit, but I want to also get the entered info after clicking back or clicking somewhere else:
For example, if the users clicks on the black space, I want to get the text they entered. If they type "hello", and click back rather than "enter", I still want to get the text hello. If, however, they don't type anything, I don't care about their input. How can I achieve this?
Thanks,

First add these as a class variables
private String inputText;
private EditText yourEditText;
Get the instance of your EditText View
yourEditText = (EditText)findViewById(R.id.your_editText);
When a button is clicked, you can get the content of the EditText field like this
Button mButton = (Button)findViewById(R.id.m_button);
mButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
inputText = yourEditText.getText().toString();
}
});
If a user press the Back button, you can get the input if any like this
#Override
public void onBackPressed() {
inputText = yourEditText.getText().toString();
super.onBackPressed();
}
Then check if there is any value assigned to your String variable
if(inputText.equals("") || inputText == null){
// there is no value
}else{
// there is value entered.
}
To extend my solution for clicking some where else
add a class variable
private boolean isEditTextHasFocus;
then create a focus listener which will check if the Edittext has focus
private View.OnFocusChangeListener focusListener = new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus){
isEditTextHasFocus = true;
} else {
isEditTextHasFocus = false;
}
}
}
Add this line in onCreate(Bundle savedInstanceState) method
yourEditText.setOnFocusChangeListener(focusListener);
Then override to onTouchEvent(MotionEvent event) listener and access the Edittext input when the key up action is called
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
if(!isEditTextHasFocus){
inputText = yourEditText.getText().toString();
}
}
return true;
}
I hope this will give you a further idea to find your unique solution.

Overriding what happens when the back button is pressed is bad practice and is unnecessary for what you want to do.
You need to use a special listener called onFocusChangedListener. This function is called anytime an element gains or loses focus. In this case for your editText it will be called whenever someone clicks on it or away. Pressing the back button or leaving the editText in any way will call this function. In the following code I check if
if(!username.hasFocus())
which makes it so the value is only saved when focus from the editText is lost rather than everytime focus is changed.
You haven't added any of your own code so I am just going to use obvious placeholder variables in my code example.
Edittext username = (EditText findViewById(R.id.YOUR_EDITTEXTS_ID);
String previousValue = ""; // to keep track of value change
String usernameValue = "";
username.setOnFocusChangeListener(new View.OnFocusChangeListener(
{
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (username.hasFocus()){
//take note of value for comparison when clicking away
previousValue = username.getText().toString();
} else if (!username.hasFocus()){
// check if value has changed
if (!previousValue.equals(username.getText().toString()){
usernameValue = username.getText().toString();
}
}
}
});

How to clear android textedit field

I am traing to clear textedit field when it is focused. I know about hint option, but I wanna clear textedit everytime when user actives it, also if is filled by user (now user have to clear field manualy everytime he wants change value).
I load fragments in my app so there are a lot of edittext fields which I wanna clear on focus, so is there universal method to do this, or I have to do it to all fields severally?
Should I create another java file to this method or put inside onCreate?

You need to add an onClickListener and set the textfield to an empty string when clicked. You need to add the listener for each textfield but you can reuse the same listener because the functionality is the same. You can set the listener on onCreate, that's fine.

You should you OnFocusChangeListener as is shown in code below:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
((EditText)v).setText("");
}
}
});

Simply set an View.OnFocusChangeListener with the method setOnFocusChangeListener(View.OnFocusChangeListener l).
In the callback onFocusChange(View v, boolean hasFocus) you can do the following:
if (hasFocus && v instanceof EditText) {
((EditText) v).setText("");
}

TextView editable onLongClick -- But one small issue when BACK button pressed

I have been search SO for days and have finally compiled enough answers to accomplish what I wanted. First off, it seems to be an often asked question but not really answered (at least not the way I was looking for it). I thought I would share my findings but I also have one small issue left that I would like to ask for help with. Here goes:
I have a TextView which displays a score. It starts at 0 and at an onClick event the score increments and updates the TextView (score is tracked as a byte - valScore).
onLongClick: This was the challenge. I want the user to be able to do a LongClick to correct/change the score. I first found a solution that utilized another layout.xml file with just an EditText element and the OK and CANCEL buttons. This was very cumbersome to change the score as it involved the LongClick, then the dialog opens, then you had to click on the EditText element to open the keyboard, then you enter the value, click DONE and then click OK. I shortened it by figuring out how to open the software keyboard automatically when the dialog opened. However, you still had to click DONE and then OK. I didn't like this action so I continued searching.
Days later I came up with a bit of code and then more and with a lot of playing/hacking around I came up with the following solution:
// set the onLongClickListener for tvScoreHome
tvScoreHome.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
tvScoreHome.setInputType( InputType.TYPE_CLASS_NUMBER );
tvScoreHome.setFocusable(true);
tvScoreHome.setFocusableInTouchMode( true );
tvScoreHome.requestFocus();
InputMethodManager imm = (InputMethodManager) context.getSystemService(Service.INPUT_METHOD_SERVICE);
imm.showSoftInput(tvScoreHome, InputMethodManager.SHOW_FORCED);
tvScoreHome.setText("");
tvScoreHome.setOnEditorActionListener( new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
valScoreHome = Byte.valueOf( tvScoreHome.getText().toString() );
// This part will hide the keyboard after input
InputMethodManager imm = (InputMethodManager) context.getSystemService(Service.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
tvScoreHome.setFocusable( false );
tvScoreHome.setFocusableInTouchMode( false );
tvScoreHome.setText( Byte.toString(valScoreHome) );
return true;
}
return false;
}
});
return true;
}
});
This works EXACTLY how I want. User performs LongClick the keyboard opens, the user enters the new value and clicks DONE. The TextView is updated and it works great!
The problem arises if the user changes their mind and hits the BACK button on the device. The keyboard closes (GOOD), but then the focus remains on the TextView instead of removing the focus like I do if the DONE button is pressed. So if you cancel out of a change every click after that results in the keyboard opening again instead of just incrementing the score -- until you actually type a value into the keyboard and click DONE (then the regular behavior takes over again. I need to setFocusableInTouchMode to FALSE if the BACK button is pressed.
The other issue is that the setText() method is executed even if the BACK button is pressed if a different value has been typed in. Even though valScoreHome isn't updated the TextView changes. On the next increment it goes to the correct number again, but the setText() should not execute if the BACK button is pressed.
Can someone help me figure this out please?

Both issues can be handled by subclassing TextView.
The back button press that closes the keyboard is handled by overriding onKeyPreIme.
To avoid updating the text when the user closes the keyboard, the score value is saved in the variable mScore, but only if the TextView is currently not focusable. That means, the TextView "remembers" the current value of the score, that was not entered by the user. When the user closes the the keyboard, the text is set back to the saved value.
public class ScoreTextView extends TextView {
private CharSequence mScore;
public ScoreTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public void setText(CharSequence text, BufferType type) {
if (!isFocusable()) {
mScore = text;
}
super.setText(text, type);
}
#Override
public boolean onKeyPreIme(int keyCode, KeyEvent event) {
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
setFocusable(false);
setFocusableInTouchMode(false);
setText(mScore);
}
return super.onKeyPreIme(keyCode, event);
}
}
