I have a number of EditText elements in my page along with two buttons. I want the user to touch on any one EditText field and click any button to insert a certain value into that very EditText field they touched. Giving input using the keypad is not allowed. Please help me to do this.
You can use View.OnFocusChangeListener to detect if any view (edittext) gained or lost focus.
for (EditText view : editList){
view.setOnFocusChangeListener(focusListener);
}
....
private OnFocusChangeListener focusListener = new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus){
focusedView = v;
} else {
focusedView = null;
}
}
}
This goes in your activity or fragment or wherever you have the EditTexts. The .... is just saying that you can put it anywhere else in the class. And obviously you would need to create an array with them in it, thus the editList.
This works for me. It returns a boolean.
myEditText.hasFocus()
One thing that you can do is declare a global variable evalue which will tell you which is the last selected EditText by using onTouchListener and then based on the value of evalue, you can set the text value to the edittext by button click. hope you understood.
the code for it can be as follow:
EditText e1,e2;
Button b1,b2;
String evalue;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
e1=(EditText)findViewById(R.id.editText1);
e2=(EditText)findViewById(R.id.editText2);
b1=(Button)findViewById(R.id.button1);
b2=(Button)findViewById(R.id.button2);
e1.setOnTouchListener(new View.OnTouchListener()
{
public boolean onTouch(View arg0, MotionEvent arg1)
{
evalue="1";
return false;
}
});
e2.setOnTouchListener(new View.OnTouchListener()
{
public boolean onTouch(View arg0, MotionEvent arg1)
{
evalue="2";
return false;
}
});
b1.setOnClickListener(new View.OnClickListener()
{
public void onClick(View arg0) {
if(evalue=="1")
{
e1.setText("yes");
}
if(evalue=="2")
{
e2.setText("yes");
}
}
});
b2.setOnClickListener(new View.OnClickListener()
{
public void onClick(View arg0) {
if(evalue=="1")
{
e1.setText("No");
}
if(evalue=="2")
{
e2.setText("No");
}
}
});
}
Its a logical coding.. not upto the mark.. if you find a better one. then use it. thank you.
This worked for me.
e1 = (EditText) findViewById(R.id.editText1);
e1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View arg0, boolean hasfocus) {
if (hasfocus) {
Log.e("TAG", "e1 focused")
} else {
Log.e("TAG", "e1 not focused")
}
}
});
With Java 8 lambdas:
EditText editTextTo = findViewById(R.id.editTextTo);
editTextTo.setOnFocusChangeListener((view, b) -> {
if (view.isFocused()) {
// Do whatever you want when the EditText is focused
// Example:
editTextFrom.setText("Focused!");
}
});
Note that the view inside the lambda function is actually an instance of an EditText.
Have your Fragment implement OnTouchListener & OnFocusChangeListener:
public class AttributesFragment extends Fragment
implements OnTouchListener, OnFocusChangeListener {
Then implement using:
#Override
public boolean onTouch(View view, MotionEvent event) {
if (view instanceof EditText) {
view.setOnFocusChangeListener(this); // User touched edittext
}
return false;
}
#Override
public void onFocusChange(View v, boolean hasFocus) {
}
Don't forget to set your listener after creating your EditText
editText.setOnTouchListener(this);
This way if an EditText box is focused by default but user has not changed the field it will not fire the onFocusChange event.
Simple Coding:
if(EditText1.isFocused()){
//EditText1 is focused
}else if(EditText2.isFocused()){
//EditText2 is focused
}
This worked for me using Java 8 (lambdas):
EditText myEditText = findViewById(R.id.editText);
myEditText.setOnFocusChangeListener((view, hasFocus) -> {
if(hasFocus){
Log.e("TAG", "myEditext has focus")
}else{
Log.e("TAG", "myEditext has no focus")
}
});
In your activity or fragment implement OnFocusChangeListener.
edittextNeme= (EditText) findViewById(R.id.edittextNeme);
edittextNeme.setOnFocusChangeListener(this);
You will have to check which view changed focus by getting the view id with view.getId() and handle accordingly.
#Override
public void onFocusChange(View view, boolean hasfocus) {
switch(view.getId()){
case R.id.edittextNeme:
//Do something
break;
...etc
}
}
val currentFocusView = activity.currentFocus
if (currentFocusView is EditText){
currentFocusView.appendText("Has Focus!")
}

I realized that the UI elements listeners are called from top down order...
(OnTouch -> OnFocusChange -> OnClick.)
So i had a setOnFocusChangeListener in the following way:
editTextPhoneNumber.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
clearIfNotMatch((EditText) v, new Integer[]{12, 13});
}
}
});
This method checks if the field was inserted correctly, if it is wrong the content of this field is deleted.
In the setOnClickListener method that where I perform the field validation it is not taking the final value of the field ... it's like it was still filled!!!
buttonRegister.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//buttonRegister.requestFocus();
startValidation();
if (validation.isValid()) {
showsNewDialog();
}
}
});
If i click on another edittext before clicking the button the validation works.
If I click directly on the button I cannot validate correctly
Code of startValidation:
private void startValidation() {
validation= new AwesomeValidation(ValidationStyle.BASIC);
validation.addValidation(editTextNumberOfSections, new FieldRequired(), getString(R.string.validation_field_required));
validation.addValidation(editTextPhoneNumber, new FieldRequired(), getString(R.string.validation_field_required));
}
Please help me!
I have two EditText widgets(editText1 and editText2) both has values populated by a button and the cursor is focussed on editText1. I have the listeners on both editText as shown in the code snippet below. With the cursor on editText1, it takes two clicks/touch to clear editText2. How can I clear editText2 with a single click/touch?
tipPercent.setOnClickListener(new EditText.OnClickListener(){
public void onClick(View view){
try{
tipPercent.setText("");
}
splitTip.setOnClickListener(new EditText.OnClickListener(){
public void onClick(View view){
try{
splitTip.setText("");
}
Screenshot of the EditText and click event
try this..
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
//clear the edittext
} else {
//set the value when hasFocus is not
}
}
});
Try this:
tipPercent.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
splitTip.setText("");
}
}
});
splitTip.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
tipPercent.setText("");
}
}
});
If i understand your question
you need to clear editText2 when its focus? then you need to use setOnFocusChangeListener when editText get focus or lost focus you may clear editText
editText2.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
//clear editText when editext get focus
Toast.makeText(getApplicationContext(), "Got the focus", Toast.LENGTH_LONG).show();
} else {
//clear editText when editext lost focus
Toast.makeText(getApplicationContext(), "Lost the focus", Toast.LENGTH_LONG).show();
}
}
});
Try this //Kotlin
private fun editTextClear(currentET: EditText, targetET: EditText) {
currentET.setFocusableInTouchMode(true)
currentET.setFocusable(true)
targetET.clearComposingText()
targetET.setFocusable(false)
}
//Now call this method onClick()
first_et.setOnClickListener {
editTextClear(first_et, second_et)
}
second_et.setOnClickListener {
editTextClear(second_et, first_et)
}
If you try to set focusable="false" for second_et you can single click on second_et from first time only to empty first_et
Hope this solves your problem
Try This:
/*EditText1*/
tipPercent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tipPercent.setText("");
}
});
/*EditText2*/
splitTip.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
splitTip.setText("");
}
});
onFocusListener will work as this will allow you to clear the text in one click, as onClickListener is not made for this kind of purpose
Hope it helps
I have Two EditTexts. I want On First EditTexts click clear the second and on second edittext click clear the first one. So I have tried OnClickListener and OnTouchListener. But it is not working properly.
et_email.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_mobile.setText("");
et_mobile.setFocusableInTouchMode(true);
et_mobile.setFocusable(true);
et_mobile.requestFocus();
}
return true; // return is important...
} else
return false;
}
});
et_mobile.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_email.setText("");
et_mobile.setFocusableInTouchMode(true);
et_mobile.setFocusable(true);
et_mobile.requestFocus();
}
return true; // return is important...
}
else
return false;
}
});
But the problem is Focus is not setting on first touch and while clicking and unable to clear EditText.
First add this to your Edittext layouts:
android:focusableInTouchMode="false"
Without this line, the EditText will react to touch-mode, and only listen to your onClick() the second time you click your EditText bar.
This will disable touch-mode for EditText, and fire onClick() in first time
focusableInTouchMode
Note: boolean that controls whether a view can take focus while in touch mode. If this is true for a view, that view can gain focus when clicked on, and can keep focus if another view is clicked on that doesn't have this attribute set to true.
than do as follows:
EditText1
EditText et_email = (EditText) findViewById(R.id.yourEditText1);
et_email.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do this
et_mobile.setText("");
//or this
et_mobile.getText().clear();
}
});
EditText2
EditText et_mobile = (EditText) findViewById(R.id.yourEditText2);
et_mobile.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do this
et_email.setText("");
//or this
et_email.getText().clear();
}
});
This should help u out.
you are clearing the first one one touching the first one, change your variable names in first listener like this
if (!(et_email.getText().toString().equalsIgnoreCase("") && et_mobile.getText().toString().equalsIgnoreCase(""))) {
if (MotionEvent.ACTION_UP == event.getAction()) {
et_mobile.setText("");
et_email.setFocusableInTouchMode(true);
et_email.setFocusable(true);
et_email.requestFocus();
}
return true; // return is important...
} else
I hope this code helps you (it works for me)
edit1 = (EditText) findViewById(R.id.edit1);
edit2 = (EditText) findViewById(R.id.edit2);
edit1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
edit2.setText("");
}
});
edit2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
edit1.setText("");
}
});
I have a vertical scrolling layout with multiple EditText and Spinner controls.
Problem is when i choose any spinner option after selection the screen scrolls back to the last EditText is was editing before this spinner. The Focus remains with the last EditText i was editing. Is there a way i can keep focus with the current selected spinner.
I am looking for a solution that can be implemented on all spinners from layout XML or some generic method to apply to all spinners.
Here's my solution.
mSpinner.setFocusableInTouchMode(true);
mSpinner.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
if (mSpinner.getWindowToken() != null) {
mSpinner.performClick();
}
}
}
});
Use this to avoid EditText Focus :
scrollView = (ScrollView) findViewById(R.id.scrollView_id);
scrollView.setOnTouchListener(new OnTouchListener() {
// to solve foocus problem on scrolling
public boolean onTouch(View v, MotionEvent event) {
if (myEditText.hasFocus()) {
myEditText.clearFocus();
}
if (myEditText1.hasFocus()) {
myEditText1.clearFocus();
}
return false;
}
});
I solved the problem with the help of Ryderz answer. here is the code :
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
scrollView = (ScrollView) findViewById(R.id.sv_main);
scrollView.setOnTouchListener(new OnTouchListener() {
// to solve focus problem on scrolling
public boolean onTouch(View v, MotionEvent event) {
IBinder windowToken = null;
if (myEditText1.hasFocus()) {
myEditText1.clearFocus();
windowToken = myEditText1.getWindowToken();
}
if (myEditText2.hasFocus()) {
myEditText2.clearFocus();
windowToken = myEditText2.getWindowToken();
}
if (myEditText3.hasFocus()) {
myEditText3.clearFocus();
windowToken = myEditText3.getWindowToken();
}
if (windowToken != null) {
imm.hideSoftInputFromWindow(windowToken, 0);
}
scrollView.requestFocusFromTouch();
return false;
}
});
Then I set the android:focusable="true" for my textViews so that on scroll when focus is removed from editText then the Textviews can be picked for focus. In that way the user doesn't see any focused control on screen.
I had the same problem like you and I've resolved with this solution.
I've redefined OnItemSelectedListener and when the spinner changes the value, I take the focus and after that, I release again.
This is my class CustomOnItemSelectedListener:
public class CustomOnItemSelectedListener implements AdapterView.OnItemSelectedListener{
private Spinner mSpinner;
private int iCurrentSelection;
public CustomOnItemSelectedListener(Spinner s){
mSpinner = s;
iCurrentSelection = mSpinner.getSelectedItemPosition();
}
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
if (iCurrentSelection != arg2) {
mSpinner.setFocusableInTouchMode(true);
mSpinner.requestFocus();
mSpinner.setFocusableInTouchMode(false);
mSpinner.clearFocus();
}
iCurrentSelection = arg2;
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
//No hace falta hacer nada
}
}
In my code I do this
Spinner spinner = (Spinner) rootView.findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(new CustomOnItemSelectedListener(spinner));
If you want to keep focus, don't do "clearFocus()".
I am trying to capture when an edittext field which is disabled gets pressed.
(I only want to change it, I dont want text inserted into it).
I assigned an onClickListener to it but it is not called.. Any suggestions ?
Is there any other event I can listen to ?
final EditText field = column.get(i);
field.setEnabled(false);
field.setClickable(true);
field.setFocusable(false);
field.setFocusableInTouchMode(false);
field.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
((EditText)v).setText("a");
}
});
Thanks !
You cant pass a click-event when a View is disabled.
Therefore, try changing:
field.setEnabled(false);
To:
field.setEnabled(true);
final EditText field = column.get(i);
field.setCursorVisible(false);
field.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
field.setText("something");
field.clearFocus();
}
}
});
