Android EditText doesn't reappear at the same place

I'm working on a Credit / Debit card form on Android.
What I'm trying to achieve:
I have an EditText field called CardNumber where the user is supposed to type in his / her card number. Upon receiving all the digits of the card number, two additional EditText fields, ExpiryDate & CVV slide out. If the user erases any of the digits in the CardNumber field, bot the ExpiryDate & the CVV fields should disappear or slide in & remove the text written on them.
When the user types in the CardNumber again & enters all the digits required, both ExpiryDate & CVV should appear again in the same place they appeared before.
But this is what I'm getting
They are not appearing in the same place. How do I achieve this & how do I remove the text from both ExpiryDate & CVV upon their disappearance.
This is what I have done so far

What am I missing?
Thank you for your time!!

You probably don't want to translate the EditText, because that's why it's placed lower on the screen than wanted.
If you anyways want to use a translate animation you have to use View.INVISIBLE instead of View.GONE, otherwise the initial getHeight() will return 0. You also need to translate to 0 for s.length()==19 and to -expiryDate.getHeight() for s.length()<19
if(s.length()==19)
{
//MAKING EXPIRY DATE VISIBLE & PUTTING FOCUS ON IT
expiryDate.setVisibility(View.VISIBLE);
expiryDate.requestFocus();
//SLIDE OUT ANIMATION (FADE IN --> FADE OUT)
expiryDate.setAlpha(0.0f);//(INVISIBLE)
expiryDate.animate().translationY(0).alpha(1.0f);//(VISIBLE)
//MAKING CVV VISIBLE
CVV.setVisibility(View.VISIBLE);
//SLIDE OUT ANIMATION (FADE IN --> FADE OUT)
CVV.setAlpha(0.0f); //(INVISIBLE)
CVV.animate().translationY(0).alpha(1.0f); //(VISIBLE)
}
else if(s.length()<19 && expiryDate.getVisibility() == View.VISIBLE)
{
//DISAPPEARING THE EXPIRY DATE 7 CVV
expiryDate.setVisibility(View.INVISIBLE);
CVV.setVisibility(View.INVISIBLE);
//CLEARING THE FOCUS
expiryDate.clearFocus();
//SLIDE IN ANIMATION (FADE OUT --> FADE IN)
expiryDate.animate().translationY(-expiryDate.getHeight()).alpha(0.0f);
CVV.animate().translationY(-CVV.getHeight()).alpha(0.0f);
}
Additionally you would want to translate the views up in your init method like this
expiryDate.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
#Override
public boolean onPreDraw() {
expiryDate.animate().translationY(-expiryDate.getHeight());
expiryDate.getViewTreeObserver().removeOnPreDrawListener(this);
return true;
}
});

Try using View.INVISIBLE instead of View.GONE.
View.GONE This view is invisible, and it doesn't take any space for layout purposes.
View.INVISIBLE This view is invisible, but it still takes up space for
layout purposes.
Also update the view XMLs from android:visibility="gone" to android:visibility="invisible" and see if it works.

You are getting height from Editext.getHeight(). When the view is not drawn it returns zero. So Second time you get some xx value. So only second time your slideout animation will happen.
If slide out animation is not your preference use animatelayoutchanges= true for view group. It will animate some standard animations. That will better.
Or you can get height from onPredrawListener.

OnClick Not Firing?

I'm new to android and having trouble getting some simple things going!
Here is some basic code:
MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Lets go ahead and set our buttons up.
ServerButton = (Button)this.findViewById(R.id.ServerButton);
ClientButton = (Button)this.findViewById(R.id.ClientButton);
BTServer = new BluetoothServerService(this, mHandler);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void ServerButtonClick(View v){
Log.d("BLUETOOTH MAIN ACTIVITY", "It got here");
BTServer.start();
}
private final Handler mHandler = new Handler(){
#Override
public void handleMessage(Message msg){
switch (msg.what){
case HANDLER_CHANGE_SERVER_STATUS:
switch(msg.arg1){
case SERVER_STATUS_OFF:
CURRENT_SERVER_STATUS = SERVER_STATUS_OFF;
//We should probably add some logging, and the change to the button
break;
case SERVER_STATUS_ON:
CURRENT_SERVER_STATUS = SERVER_STATUS_ON;
//Again lets add some logging, etc.
break;
case SERVER_STATUS_ON_CONNECTED:
CURRENT_SERVER_STATUS = SERVER_STATUS_ON_CONNECTED;
//Again lets add some logging, etc.
break;
}
}
return;
}
};
My XML Looks like this:
<Button
android:id="#+id/ServerButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="146dp"
android:layout_marginLeft="64dp"
android:text="Connect to Server" />
<Button
android:id="#+id/ClientButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="28dp"
android:text="Start Server"
android:onClick="ServerButtonClick"/>
In my logs, I see the logs saying it creates the BTServer object, but I can't get any logs to show up when I click the button.
Any suggestions?
Thanks!

define a click action for ClientButton inside onCreate method
ClientButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
}
});
also for ServerButton define a click action like the above as
ServerButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
}
});

For me, I find it's best to have your Activity implement android.view.View.OnClickListener, then set your Button's onClickListener to your Activity.
Here's an example Activity class:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Home extends Activity implements OnClickListener
{
#Override
public void onCreate (Bundle savedInstanceState)
{
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_main);
Button serverButton = (Button)this.findViewById (R.id.ServerButton);
serverButton.setOnClickListener (this);
Button clientButton = (Button)this.findViewById (R.id.ClientButton);
clientButton.setOnClickListener (this);
}
#Override
public void onClick(View button)
{
int buttonId = button.getId ();
if (buttonId == R.id.ServerButton)
{
// Do server stuff.
}
if (buttonId == R.id.ClientButton)
{
// Do client stuff.
}
}
}

In Android when you define the android:onClick="someMethod" attribute it only implements the OnClickListener for you.
So it is your responsibility to define the onCLickListener Method and call your ServerButtonClick method from that.
Add this method in your Activity OnCreate Method. It would work.
ServerButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
ServerButtonClick();
}
});
Also, android:onClick method works only if API level > 4 onwards. so if you're targeting Minimum SDK version < 1.6 please do not use it

android app crashing and list view not showing

CheckBoxPreference not ticking when selected in PreferencesActivity

When I click the "Settings" page, my CheckBoxPreference shows exactly how I want it to at this stage, however when I select it, the state does not change (i.e. from Unchecked to Checked).
It seems to be retaining the value of false (default) and still running onPreferenceChanged with false as the value passed. I am running code inside my onPreferenceChangedListener that is dependent on the value of the preference that is changed. As it stands I only have one preference in here.
activity_preferences.xml:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceScreen>
<CheckBoxPreference
android:summaryOn="true"
android:summaryOff="false"
android:key="isReg"
android:title="Receive Push Messages"
android:selectable="true"
android:enabled="true"
android:persistent="true" />
</PreferenceScreen>
</PreferenceScreen>
PrefsActivity.java:
import android.os.Bundle;
import android.preference.CheckBoxPreference;
import android.preference.Preference;
import android.preference.Preference.OnPreferenceChangeListener;
import android.preference.PreferenceActivity;
import com.google.android.gcm.GCMRegistrar;
public class PrefsActivity extends PreferenceActivity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.activity_preferences);
Preference isReg = (Preference) findPreference("isReg");
isReg.setOnPreferenceChangeListener(new OnPreferenceChangeListener(){
public boolean onPreferenceChange(Preference pref, Object arg1) {
boolean isReg = getSharedPreferences("PREFERENCE", MODE_PRIVATE).getBoolean("isReg", false);
if (isReg){
ServerUtilities.register(getApplicationContext(), GCMRegistrar.getRegistrationId(getApplicationContext()));
}
else {
ServerUtilities.unregister(getApplicationContext(), GCMRegistrar.getRegistrationId(getApplicationContext()));
}
return isReg;
}
});
}
}

You are using the wrong preference widget as per in the code sample,
Preference isReg = (Preference) findPreference("isReg");
It should have been CheckBoxPreference as in
CheckBoxPreference isReg = (CheckBoxPreference) findPreference("isReg");
Edit
One thing I noticed, you're not handling the preference activity properly...consider this code, always, call the preference's commit method in order to save it!
public class PrefsActivity extends PreferenceActivity implements
OnSharedPreferenceChangeListener{
CheckBoxPreference isReg;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.activity_preferences);
PreferenceManager.setDefaultValues(this,R.xml.activity_preferences, false);
isReg = (CheckBoxPreference)findPreference("isReg");
if (isReg != null){
isReg.setOnPreferenceChangeListener(new OnPreferenceChangeListener(){
#Override
public boolean onPreferenceChange(Preference preference,
Object newValue) {
boolean blnIsReg = Boolean.getBoolean(newValue.toString());
Editor e = _prefs.edit();
e.putBoolean("isReg", blnIsReg);
e.commit();
return true;
}
});
}
}
}
#Override
public void onStart(){
super.onStart();
_prefs = PreferenceManager.getDefaultSharedPreferences(this);
}
The listener that is implemented must be in this fashion, which is how the changes are effective:
#Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
Log.d(TAG, "onSharedPreferenceChanged; key = " + key);
}
By incorporating the listener, the logcat will show that the preference's key is indeed being changed, i.e. "isReg".

Update the values from the shared preferences in onResume()
method

SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(PrefsActivity.this);
boolean isReg = prefs.getBoolean("isReg", false);
Hope Try This it will help You

EditText on demand widget

I'd like to have a TextView display text, and when you click/longclick on it, a textbox should "show up" and allow editing of said text. When you're done editing (onkey enter i suppose) it should revert back to a textview with the updated text...
I'm wondering if it's feasable to implement such a widget or should I hack a workaround? Tips and suggestions are very welcome.
If you need further idea of what I mean, just go to your e.g. (windows) skype profile and see for yourself.
EDIT:
Clarification: I'm specifically asking for a widget or such which is a textview until clicked on, then transforms to an edittext containing the same text; once done editing it transforms back to a textview representing the new changed text. Thats what i mean by "edittext on demand widget".
But I'm hoping to get something better than
public class Widget {
TextView text;
EditText edit;
String textToRepresent;
//...
}

You have a few different options here.
First you will have to register an onClick or onLongClick to the TextView that you want to make interactive. Just make sure that the user knows it's clickable
Then have your onClick function start a DialogFragment. I like to create show functions. Note that you can use the support libraries here to make your app backwards compatible.
private void showDialog() {
MyDialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "dialog");
}
The DialogFragment is pretty straight forward. In your onCreateView you'll inflate the View that you'll want to display to the user. You can alternatively wrap it with a simple AlertDialogBuilder if you don't want to go custom.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.your_dialog_layout);
mTitleEditText = (TextView) view.findViewById(R.id.title);
mTitleEditText.setOnClickListener(this);
return view;
}
After your findViewByIds set your onClickListeners.
The last thing you have to take care of is getting data back into your original TextView.
You can do this by creating a public method in your Activity that you can call from inside of your DialogFragment. Something like this
#Override
public void onClick(View v) {
int clickedId = v.getId();
if (clickedId == mDoneButton.getId()) {
MyActivity activity = (MyActivity)getActivity();
mTitle = mTitleEditText.getText().toString();
activity.setText(mTitle);
dismiss();
}
}
I would recommend using a DialogFragment because it will handle your life cycle nicely.
However, another option would be to create a new Activity themed to be a dialog
<activity android:theme="#android:style/Theme.Dialog" />
Then you can startActivityForResult to display your dialog and then capture your results in onActivityResult

Here is my solution. I just give you the basic one. Create a TextView in front of EditText and two Button OK,Cancel (You can change to ImageButton like Skype). Change the visiblity of two view. The code is so simple without comment. You can add some null checking according your logic.
public class CompoundTextView extends RelativeLayout implements OnClickListener {
private EditText edt;
private TextView txt;
RelativeLayout layout;
public SkypeTextView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
#Override
protected void onFinishInflate() {
super.onFinishInflate();
edt = (EditText) findViewById(R.id.edt);
txt = (TextView) findViewById(R.id.txt_name);
layout = (RelativeLayout) findViewById(R.id.layout);
Button ok = (Button) findViewById(R.id.ok_btn);
Button cancel = (Button) findViewById(R.id.cancel_btn);
ok.setOnClickListener(this);
cancel.setOnClickListener(this);
txt.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.ok_btn:
String editString = edt.getText().toString();
txt.setText(editString);
layout.setVisibility(View.INVISIBLE);
txt.setVisibility(View.VISIBLE);
break;
case R.id.cancel_btn:
layout.setVisibility(View.INVISIBLE);
txt.setVisibility(View.VISIBLE);
break;
case R.id.txt_name:
txt.setVisibility(View.INVISIBLE);
layout.setVisibility(View.VISIBLE);
break;
}
}
}
Create a XML skypetextview. You can customize font and background to make it's prettier.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/txt_name"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:textColor="#FFFFFF"
android:textSize="14sp"
android:background="#ff0000" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible"
android:id="#+id/layout" >
<EditText
android:id="#+id/edt"
android:layout_width="270dp"
android:layout_height="100dp" />
<Button
android:id="#+id/ok_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/edt"
android:text="OK" />
<Button
android:id="#+id/cancel_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/ok_btn"
android:layout_toRightOf="#id/edt"
android:text="Cancel" />
</RelativeLayout>
</RelativeLayout>
add (or include) this view to the layout you want.
Example :
public class TestActivity extends Activity {
SkypeTextView test;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater inflate = getLayoutInflater();
test = (SkypeTextView ) inflate.inflate(R.layout.compound_text_view,
null);
setContentView(test);
}
PS: i forgot. You should add some underline format for your textview in order to make user notice it clickable

Let a EditText change its background based on its state(Editable or Frozen). Set a background selector that does this.
Use this selector xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="#android:drawable/edit_text"/>
<item android:drawable="#android:drawable/screen_background_light_transparent"/>
</selector>

Like I said on thursday... Yul was pretty close but not quite close. He did have a general same idea but (theoretically) rushed into code too early ;)
The TextBoxOnDemand code supplied below is production-ready. The idea is similar to what I wanted to avoid in the OP and what Yul suggested, but with optimal implementation (using a ViewSwitcher instead of a RelativeLayout for instance)
I gathered the resources needed for this in the following articles:
Creating custom view from xml
Declaring a custom android UI element using XML
Defining custom attrs
How to pass custom component parameters in java and xml
http://kevindion.com/2011/01/custom-xml-attributes-for-android-widgets/
and decided to post them here because the official Google "training" docs are useless and are either obsolete (deprecated) or do not cover what I needed. I hope you don't mind me claiming my own bounty, but this is the solution I wanted (and expected, ergo the bounty).
I guess the code will have to do ;)

I'm still working out some focus-related issues but this works as intended. When I use onFocuslistener 1, you can't focus from one TextBox to the other; when the textbox itself is focusable, I can focus from one to the other just fine, but I cannot inter-focus thru children and thus can't focus on the edittext to type.
the XML file:

EDIT: I've debugged the focus issues. It turns out that giving focus to children is difficult unless you call
setDescendantFocusability(FOCUS_AFTER_DESCENDANTS);
Which kinda remedies the issue but still doesn't solve it. After some while of playing around with the onFocusChange() listener still trying to get the perfect behaviour, I threw in the towel and put in added two focus guards. I realized I cannot track the loss of focus only on my container (due to it never receiving focus) but I might as well track the idea of wanting to move away from the edit field... So i went the dirty route and added two invisible bar-like views to sandwitch the edittext in between. Once they got the focus, I could hide the component and ensure they transition properly.
And there it is, now it works as it should. Thanks to all who participated.
EDIT3: final polished version, i dumped the custom tags because they simply don't work reliably enough. Lesson to be learned: if there is an android tag for something, don't bother cloning it.
