Onclick event not working in android

Onclick event not working in android - android

I have written a code to enter some text using button click events in android. It is not working at all. Not giving any error or exception,i am not getting where it is all going wrong.
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//select_btn = (Button) findViewById(R.id.ok);
//home_btn = (Button) findViewById(R.id.home);
et = (EditText) findViewById(R.id.entry);
et.setText("", TextView.BufferType.EDITABLE );
b = new Bundle();
for (int i = 0; i < mybtn.length; i++) {
String btnid = "btn" + i;
int resid = getResources().getIdentifier(btnid, "id",
getPackageName());
mybtn[i] = (Button) findViewById(resid);
mybtn[i].setOnClickListener(this);
}
//tts.speak("hello wolrd",TextToSpeech.QUEUE_FLUSH,null);
et.setText("hello man", TextView.BufferType.EDITABLE );
}
public void onClick(View v)
{
//while(tts.isSpeaking());
et.setText("hello android", TextView.BufferType.EDITABLE );
String s=null;
s = ((Button)v).getText().toString().trim();
//tts.speak("hello google",TextToSpeech.QUEUE_FLUSH,null);
}

In your code you are passing the activity into the setOnClickListener() method by mybtn[i].setOnClickListener(this) where this is a reference to your activity. The setOnClickListener() expects as a parameter a View.OnClickListener interface. That is any object that implements the View.OnClickListener Interface. There are two ways that you might do this.
1) Create an anonymous object e.g.
mybtn[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
... your code here
}
});
the new OnClickListener() creates an anonymous object, it is anonymous because we do not store a reference to it.
2) Pass in an object that implements the View.OnClickListener(). If you wanted to pass in your activity object to setOnClickListener() you would have to have it declare that it implements View.OnClickListener() and additionally Override the public void onClick(View v) method e.g.
public class YourActvivity extends Activity implements View.OnClickListener {
onCreate() {
}
....etc
//implement the View.OnClickListener interface
#Override
public void on Click(View v) {
...your code here
}
because you have an array of buttons and calling setOnClickListener(this) where this is your activity this one method will be called for each of your buttons, so if you want each button to do something different you would have to compare the view id that was the source of the click event with the button id in your xml, otherwise all buttons will behave in exactly the same way when clicked.
to find out which button was clicked you can check like this
switch(v.getId()) {
case R.id.btn0:
...do button 0 stuff;
break;
case R.id.btn1:
...do button 1 stuff;
break;
...etc
}
the view that is passed into the onClick() callback is the view that the click event originated from and is referenced here simply as v onClick(View v). This second method will work for any object (Class) that declares and implements View.OnClickListener.

*UPDATE*
Oh sorry...
I think you have a problem with your listener registration, try this instead :
b=findViewById(R.id.btnid);
b.setOnClickListener(this);
b.setOnClickListener(new OnClickListener(){
public void onClick(View view) {
et.setText("hello android", TextView.BufferType.EDITABLE );
String s=null;
s = ((Button)v).getText().toString().trim();
}
});

In the layout add:
android:onClick="onClick"
to the Button on which you want to handle click...

You are reading the text of the clicked button to a string variable, but not using it.
This should be more like what you are trying to achieve:
public void onClick(View v)
{
// et.setText("hello android", TextView.BufferType.EDITABLE );
String s=null;
s = ((Button)v).getText().toString().trim();
et.setText(s, TextView.BufferType.EDITABLE );
}

Make sure your activity is like below
public class MyActivity extends Activity implements OnClickListener
{
Button b;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//select_btn = (Button) findViewById(R.id.ok);
//home_btn = (Button) findViewById(R.id.home);
et = (EditText) findViewById(R.id.entry);
et.setText("", TextView.BufferType.EDITABLE );
b=findViewById(R.id.btnid);
b.setOnClickListener(this);
b = new Bundle();
for (int i = 0; i < mybtn.length; i++) {
String btnid = "btn" + i;
int resid = getResources().getIdentifier(btnid, "id",
getPackageName());
mybtn[i] = (Button) findViewById(resid);
mybtn[i].setOnClickListener(this);
}
//tts.speak("hello wolrd",TextToSpeech.QUEUE_FLUSH,null);
et.setText("hello man", TextView.BufferType.EDITABLE );
}
public void onClick(View v)
{
if(v.equals(b))
{
//while(tts.isSpeaking());
et.setText("hello android", TextView.BufferType.EDITABLE );
String s=null;
s = ((Button)v).getText().toString().trim();
//tts.speak("hello google",TextToSpeech.QUEUE_FLUSH,null);
}
}
}

try this
{
............
int[] mybtn = new int[] {R.id.btn1,......R.id.btn11};
for(int i=0; i<mybtn.length; i++) {
Button b = (Button) findViewById(mybtn[i]);
b.setOnClickListener(this);
}

In
onCreate()
method you should have to mention
et.setOnClickListener(this);
Then override the
onClick(View v)
{
//Your code here
}
This will work!

Buttons Overlap

I made a stopwatch using chronometer with four buttons but when i use the visibility modes to make stop and pause button appear they overlap.... Pls explain why...Below is the code.....
Assume the layout file with buttons in relative layout...
public class StopWatchFragment extends Fragment {
Chronometer chronometer;
Button startStopWatch;
Button stopStopWatch;
Button resetStopWatch;
Button pauseStopWatch;
Button resumeStopWatch;
private long lastPause;
//RelativeLayout relativeLayout;
private int check = 0;
public StopWatchFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.stopwatch_layout,container,false);
chronometer = (Chronometer) rootView.findViewById(R.id.stopwatch);
startStopWatch = (Button) rootView.findViewById(R.id.startStopWatch);
stopStopWatch = (Button) rootView.findViewById(R.id.stopStopWatch);
resetStopWatch = (Button) rootView.findViewById(R.id.resetStopWatch);
pauseStopWatch = (Button) rootView.findViewById(R.id.pauseStopWatch);
resumeStopWatch = (Button) rootView.findViewById(R.id.resumeStopWatch);
relativeLayout = (RelativeLayout) rootView.findViewById(R.id.parentRelativeLayout);
pauseStopWatch.setVisibility(View.GONE);
//final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(relativeLayout.getLayoutParams());
startStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.start();
startStopWatch.setVisibility(View.GONE);
pauseStopWatch.setVisibility(View.VISIBLE);
if(check == 1){
resumeStopWatch.setClickable(true);
}
else{
resumeStopWatch.setClickable(false);
}
//params.setMargins(16,16,16,16);
//pauseStopWatch.setLayoutParams(params);
}
});
pauseStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
check = 1;
lastPause = SystemClock.elapsedRealtime();
chronometer.stop();
}
});
resumeStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(chronometer.getBase() + SystemClock.elapsedRealtime() - lastPause);
chronometer.start();
resumeStopWatch.setClickable(false);
}
});
stopStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.stop();
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
resumeStopWatch.setClickable(false);
}
});
resetStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.stop();
resumeStopWatch.setClickable(false);
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
}
});
return rootView;
}
}
This is the layout file pls refer for this....

This is the way buttons work when click on start button

You are hiding the button, but you are still listening with the OnClickListener. Try adding:
pauseStopWatch.setOnClickListener(null);
Then, when you make your button visible:
pauseStopWatch.setOnClickListener(whatever);

Try this layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:id="#+id/parentRelativeLayout"

<Chronometer
android:layout_centerInParent="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="30sp"
android:textAlignment="center"
android:id="#+id/stopwatch"
android:layout_margin="16dp"/>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/stopwatch">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<LinearLayout
android:gravity="center"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<Button
android:id="#+id/startStopWatch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start"
android:background="#drawable/buttonshape"
android:textSize="24sp" />
<Button
android:visibility="gone"
android:id="#+id/pauseStopWatch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Pause"
android:background="#drawable/buttonshape"
android:textSize="24sp" />
<Button
android:id="#+id/stopStopWatch"
android:layout_marginTop="16dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/startStopWatch"
android:background="#drawable/buttonshape"
android:text="Stop"
android:textSize="24sp"/>
</LinearLayout>
<LinearLayout
android:gravity="center"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<Button
android:id="#+id/resetStopWatch"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/buttonshape"
android:text="Reset"
android:textSize="24sp" />
<Button
android:id="#+id/resumeStopWatch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/buttonshape"
android:text="Resume"
android:textSize="24sp"
android:layout_marginTop="16dp"
android:layout_alignParentRight="true"
android:layout_below="#id/resetStopWatch"/>
</LinearLayout>
</LinearLayout>
In the above, the pause button will be set to Gone. You make it visible later when user clicks start button

how to make Relative layout onclick work?

I have a Relative layout as:
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
I want my relative layout to perform onCLickListener but does not work.
I am able to do the setonclicklistener but it works only with the textview part and not for the image.
btniPay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//for ipay
}
});
This works for the text part only but not for the image. Any idea what I might be missing.

Alternatively, you can add android:clickable="false" in your button xml attribute.
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/i_pay"
android:textAllCaps="false"
android:clickable="false"
android:textColor="#ffffff" />
</RelativeLayout>

may be you can find some good example thats use with imageview and buttons but the easy way i did it by using adding TextView instead of images and buttons.
<RelativeLayout
android:id="#+id/layout1"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:clickable="true"
android:gravity="right">
<TextView
android:id="#+id/englishheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/urduheading1"
android:text="English text"
android:textColor="#ffffff"
android:textSize="15sp" />
<TextView
android:id="#+id/urduheading1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="15dp"
android:text="urdu text1"
android:textColor="#ffffff"
android:textSize="16sp" />
<View
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_alignParentBottom="true"
android:layout_marginTop="8dp"
android:background="#ffffff" />
</RelativeLayout>
Here is java code to perform onClick.
RelativeLayout layout1 = (RelativeLayout) view.findViewById(R.id.layout1);
layout1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do something
}
});

see my code easily run change your code:
.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<RelativeLayout
android:id="#+id/iPay_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="· Use iPay"
android:textColor="#686A86"
android:textSize="18sp" />
<Button
android:id="#+id/btn"
android:layout_width="50dp"
android:layout_height="35dp"
android:layout_alignParentRight="true"
android:background="#drawable/ic_launcher"
android:textAllCaps="false"
android:textColor="#ffffff" />
</RelativeLayout>
</RelativeLayout>
.java file
public class MainActivity extends Activity {
TextView tv;
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView) findViewById(R.id.tv);
btn = (Button) findViewById(R.id.btn);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "text", Toast.LENGTH_SHORT).show();
}
});
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "button", Toast.LENGTH_SHORT).show();
}
});
}
}

Just mark android:clickable="true" in your RelativeLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_id"
android:clickable="true">
Using ButterKnife lib make bind here:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_xml_name);
ButterKnife.bind(this);
}
#OnClick(R.id.activity_id)
void onActivityClick() {
// do smth ...
}

Default pin lock screen layout

I want to provide lock screen, so every time user opens my app, he will be forced to enter pin. So I am looking for Android's default pin lock layout (as shown on image), which should work from Android 4.0. Can you tell me where to find layout of this or how to implement it properly?

I git below project from github and little changed it to provide a GUI like your image :
https://github.com/chinloong/Android-PinView
so create a project and in mainActivity insert this codes:
public class PinEntryView extends Activity {
String userEntered;
String userPin="8888";
final int PIN_LENGTH = 4;
boolean keyPadLockedFlag = false;
Context appContext;
TextView titleView;
TextView pinBox0;
TextView pinBox1;
TextView pinBox2;
TextView pinBox3;
TextView statusView;
Button button0;
Button button1;
Button button2;
Button button3;
Button button4;
Button button5;
Button button6;
Button button7;
Button button8;
Button button9;
Button button10;
Button buttonExit;
Button buttonDelete;
EditText passwordInput;
ImageView backSpace;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
appContext = this;
userEntered = "";
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main_layout);
//Typeface xpressive=Typeface.createFromAsset(getAssets(), "fonts/XpressiveBold.ttf");
statusView = (TextView) findViewById(R.id.statusview);
passwordInput = (EditText) findViewById(R.id.editText);
backSpace = (ImageView) findViewById(R.id.imageView);
buttonExit = (Button) findViewById(R.id.buttonExit);
backSpace.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
passwordInput.setText(passwordInput.getText().toString().substring(0,passwordInput.getText().toString().length()-2));
}
});
buttonExit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Exit app
Intent i = new Intent();
i.setAction(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
appContext.startActivity(i);
finish();
}
}
);
//buttonExit.setTypeface(xpressive);
buttonDelete = (Button) findViewById(R.id.buttonDeleteBack);
buttonDelete.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (keyPadLockedFlag == true)
{

note : userPin variable is your password and you can change it.
in below bock in activity class you should insert your code that you want execute if user enter correnct password (e.g start a new activity )
if (userEntered.equals(userPin))
{
statusView.setTextColor(Color.GREEN);
statusView.setText("Correct");
Log.v("PinView", "Correct PIN");
finish();
}
Note: add below line to main activity node in mainfist.xml file
android:theme="#android:style/Theme.NoTitleBar"
so your Activity node must be like :
<activity
android:name="com.example.MainActivity"
android:theme="#android:style/Theme.NoTitleBar"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

I clicked on my clear button and it doesn't work

THANK YOU FOR ALL OF YOUR HELP!! I NEED TO READ A TUTORIAL. :)
I know it's probably elementary and as you can tell I'm a newbie. I compared my code to others and don't see anything wrong. Thanks! When I click the clear Button after entering data, my edit fields are not cleared.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button clear = (Button)findViewById(R.id.btn_clear);
clear.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
EditText potsize = (EditText) findViewById(R.id.et_pot_size);
EditText tocall = (EditText) findViewById(R.id.et_to_call);
EditText bepercent = (EditText) findViewById(R.id.et_be_per);
potsize.setText("");
tocall.setText("");
bepercent.setText("");
TextView potoddscalc = (TextView)findViewById(R.id.tv_pot_odds_calc);
potoddscalc.setText("5");
}
});

Try this instead. I believe your problem may be arising from creating new EditTexts and TextView objects every time you click the clear button. In the below code, the EditTexts and TextView are declared only once ,in the OnCreate method. Also, getText().clear() is the "official" way of clearing the text from an EditText (not that it really makes a visual difference).
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button clear = (Button)findViewById(R.id.btn_clear);
EditText potsize = (EditText) findViewById(R.id.et_pot_size);
EditText tocall = (EditText) findViewById(R.id.et_to_call);
EditText bepercent = (EditText) findViewById(R.id.et_be_per);
TextView potoddscalc = (TextView)findViewById(R.id.tv_pot_odds_calc);
clear.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
potsize.getText().clear();
tocall.getText().clear();
bepercent.getText().clear();
potoddscalc.setText("5");
}
});
}

// try this way

SqlLiteExample.java :
public class SqlLiteExample extends Activity implements OnClickListener, OnCheckedChangeListener {
Button sqlUpdate, sqlView;
EditText etName,etAge,etContact;
RadioGroup rdgrp;
RadioButton selectedRadioButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sqlliteexample);
sqlUpdate = (Button) findViewById(R.id.savebutton);
etName = (EditText) findViewById(R.id.editName);
etAge = (EditText) findViewById(R.id.editAge);
etContact = (EditText) findViewById(R.id.editContact);
rdgrp.setOnCheckedChangeListener(this);
sqlView = (Button) findViewById(R.id.viewbutton);
sqlView.setOnClickListener(this);
sqlUpdate.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.savebutton:
boolean didWork = true;
try{
String name = etName.getText().toString();
String age = etAge.getText().toString();
String contact = etContact.getText().toString();
MyDB entry = new MyDB(SqlLiteExample.this);
entry.open();
entry.createEntry(name,age,contact);
entry.close();
}catch(Exception e){
didWork = false;
String error = e.toString();
Dialog d = new Dialog(this);
d.setTitle("Error");
TextView tv = new TextView(this);
tv.setText(error);
d.setContentView(tv);
d.show();
}finally{
if(didWork){
Dialog d = new Dialog(this);
d.setTitle("Updated");
TextView tv = new TextView(this);
tv.setText("Success");
d.setContentView(tv);
d.show();
}
}
break;
case R.id.viewbutton:
Intent i = new Intent("com.bysakiralam.mydatabase.DISPLAYRECORDS");
startActivity(i);
break;
}
}
#Override
public void onCheckedChanged(RadioGroup arg0, int arg1) {
// TODO Auto-generated method stub
switch(arg1){
case R.id.malebutton:
break;
case R.id.femalebutton:
break;
}
} }

There is no need to override onCheckedChanged() use following in your on savebutton click
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= (RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();
and now use radiovalue to store in database
Edit: forget (
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();

try this
myRadioGrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(myRadioGrp.getCheckedRadioButtonId())).getText().toString();

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Onclick event not working in android - android

In the layout add: android:onClick="onClick" to the Button on which you want to handle click...

try this { ............ int[] mybtn = new int[] {R.id.btn1,......R.id.btn11}; for(int i=0; i<mybtn.length; i++) { Button b = (Button) findViewById(mybtn[i]); b.setOnClickListener(this); }

In onCreate() method you should have to mention et.setOnClickListener(this); Then override the onClick(View v) { //Your code here } This will work!
