I have a form for member registration in my android app, I have applied the animation effect on fields which are required (some EditText views in this case) if those fields are not filled the effect should occur then like this :
mEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View arg0, boolean arg1) {
// TODO Auto-generated method stub
if (mEditText.getText.equals("")) {
mEditText.setAnimation(MyAnimation.animate());}
and MyAnimation.animate() is like :
public class MyAnimation {
public static Animation animate(){
TranslateAnimation mAnimate = new TranslateAnimation(0, 5, 0, 0);
mAnimate.setInterpolator(new CycleInterpolator(50));
mAnimate.setDuration(600);
return mAnimate;
}
}
but the problem is it occurs when the mEditText gains the focus, and my need is this should occur on focus leave if mEditText is empty.
Implement setOnFocusChangeListener and check there's a boolean parameter for hasFocus. When this is false, you've lost focus to another control.
EditText txtEdit= (EditText) findViewById(R.id.edittxt);
txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus)
{
//do job here owhen Edittext lose focus
if (mEditText.getText().equals("")) {
mEditText.setAnimation(MyAnimation.animate());}
}
}
});

I have two EditTexts in an activity. I am trying to implement it so that when one EditText is focused, the second one looks like it is focused too (the underline must be bold as it is when EditText is focused).
I am trying to change underline like this when focus changes:
editText1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
// here editText2 must have not state
} else {
// here editText2 must have not state
}
}
});
But how can I make the underline bold on another text without it actually receiving focus?
Try this
editText1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
editText2.setTypeface(Typeface.NORMAL);
} else {
editText2.setTypeface(Typeface.DEFAULT_BOLD);
}
}
});
I have three different Edit Text with restriction of entering only numeric values, thus tapping on any one of the Edit Text opens NUMERIC KEYBOARD.
I tried to implement setOnFocusChangeListener for all Edit Text which ensures that when user tap anywhere outside any of the Edit Text hide the keyboard.
editText1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
hideKeyboard(v);
}
}
});
editText2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
hideKeyboard(v);
}
}
});
editText3.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
hideKeyboard(v);
}
}
});
And here is the implementation of 'hideKeyBoard'
public void hideKeyboard(View view) {
InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
This works fine, however, when I change focus from one EditText to another EditText, keyboard hides. This behaviour might be frustrating for user.
How can I deal with it and avoid unnecessary hiding of keyboard.
P.S I need to ensure that keyboard is numeric not alphabetical in any case.
Thank you MarianoZorrila for correcting me on my approach to the problem.Here are the changes I performed to solve this problem.
Gave an Id to my Relative Layout
<RelativeLayout
...
...
android:id="#+id/parent">
Modifications to Java File
View parent = findViewById(R.id.parent);
parent.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if(hasFocus){
hideKeyboard(view);
}
}
});
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 have several EditText fields which I want to save to the SQLiteDatabase with setOnFocusChangeListener. Do I have to set an onFocusChangeListener on each one individually, or is there a catch-all of some sort? (getActivity().findViewByID because this is a fragment)
final TextView txtName = (TextView)getActivity().findViewById(R.id.clientHeader);
final TextView txtCompany = (TextView)getActivity().findViewById(R.id.txtContactCompany);
final TextView txtPosition = (TextView)getActivity().findViewById(R.id.txtContactPosition);
txtName.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
saveThisItem(txtClientID.getText().toString(), "name", txtName.getText().toString());
}
}
});
txtCompany.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
saveThisItem(txtClientID.getText().toString(), "company", txtCompany.getText().toString());
}
}
});
txtPosition.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
saveThisItem(txtClientID.getText().toString(), "position", txtPosition.getText().toString());
}
}
});
Like... is there some way to have a ArrayList < EditText > of EditText Views, assign a pointer (sorry, not sure how) to the existing editTexts and set the onFocusChangeListener to the whole arraylist? Or, even, iterate through the ArrayList and set the onFocusChangeListener to each member?
Or a way to detect ANY onFocusChangeListener events, and just save all data to the database, regardless of what EditText the even occurred on?
Well, you could have your activity implement OnFocusChangeListener. That way, all your changes will be on that one metho,d but you will have to check which view changed focus by getting the view id with v.getId() and handle accordingly.
#Override
public void onFocusChange(View v, boolean hasFocus) {
switch(v.getId()){
case r.id.editText1:
break;
...etc
}
}
There's plenty of ways you could make this simpler. For one, how about abstracting this into a method and calling it for each TextView you want to add the event for:
private void setOnFocusChangeListener(TextView textView, String name){
textView.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
saveThisItem(txtClientID.getText(), name,
textView.getText());
}
}
});
}
Then you can call this method for each of your TextView instances:
setOnFocusChangeListener(txtName, "name");
setOnFocusChangeListener(txtCompany, "company");
setOnFocusChangeListener(txtPosition, "position");
My suggestion would be to use a custom EditText to handle this for you:
public class SaveEditText extends EditText implements View.OnFocusChangeListener {
private String mDataKey;
private String mClient;
public SaveEditText (Context context) {
super(context);
setOnFocusChangeListener(this);
}
public SaveEditText (Context context, AttributeSet attrs) {
super(context, attrs);
setOnFocusChangeListener(this);
}
public void setDataKey (String dataKey) {
mDataKey = dataKey;
}
public void setClient (String client) {
mClient = client;
}
#Override
public void onFocusChange (View v, boolean hasFocus) {
saveThisItem(mClient, mDataKey, getText().toString());
}
}
You might decide to handle the client and data keys differently, but the idea is that you use a custom base class that will handle it automatically.
Or even simpler
OnFocusChangeListener listener;
listener = new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
//Do something
}
};
textbox1. setOnFocusChangeListener(listener);
textbox2. setOnFocusChangeListener(listener);
textbox3. setOnFocusChangeListener(listener);
Since onFocusChange(View v, boolean hasFocus) has the parameter View you can use that to tell which view called it
I have this application where field 1 is edittext and field 2 is textfield.
I want to add date into textview depending on the data entered in edittext field. That is after entering the data in edittext field and when i move to next edittext field the textview of 1st edittext field must be updated.
I know about add textchangedlistener but if it is the solution how am i supposed to implement it.
EDIT : I tried setonfocuschanged but it din work
k1_e.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View arg0, boolean arg1) {
// TODO Auto-generated method stub
if((v_k1>=5.63)&&(v_k1<=11.25)){
k1_m.setText("mm");
}else if((v_k1>=30)&&(v_k1<=60)){
k1_m.setText("D");
}
}
});
k2_e.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if((v_k2>=5.63)&&(v_k2<=11.25)){
k2_m.setText("mm");
}else if((v_k2>=30)&&(v_k1<=60)){
k2_m.setText("D");
}
}
});
edit 2 :
and details here
dr=Float.parseFloat(dr_e.getText().toString());
k1=Float.parseFloat(k1_e.getText().toString());
k2=Float.parseFloat(k2_e.getText().toString());
al=Float.parseFloat(al_e.getText().toString());
al_const=Float.parseFloat(alconst_e.getText().toString());
v_k1=Float.valueOf(k1);
v_k2=Float.valueOf(k2);
EDIT 3 :
I get data into edittext fields using
if(dr_e.getText().toString().length()==0|k1_e.getText().toString().length()==0|k2_e.getText().toString().length()==0|al_e.getText().toString().length()==0|alconst_e.getText().toString().length()==0){
flag=1;
}else{
dr=Float.parseFloat(dr_e.getText().toString());
al=Float.parseFloat(al_e.getText().toString());
al_const=Float.parseFloat(alconst_e.getText().toString());
}
Try this
you can use onFocusChangeListener on youredittext
k1_e.setOnFocusChangeListener(new View.OnFocusChangeListener() {
public void onFocusChange(View arg0, boolean arg1) {
String data=k1_e.getText().toString().trim();
if(data.length!=0)
{
k1=Float.parseFloat(data);
v_k1=Float.valueOf(k1);
if((v_k2>=5.63)&&(v_k2<=11.25)){
k2_m.setText("mm");
}else if((v_k2>=30)&&(v_k1<=60)){
k2_m.setText("D");
}
}
}
});
