How to design this component in Android

How to design a component in Android such as, for instance in the below image, when click on the "Select a session" button, a form filled in will appear below, and if you click again, such form will disappear?
I have just able to pop up a dialog when clicking on the component, however, what I want is to let the component appear right below the component like showing in the image.
Below is the link of how such a component looks like.
All of your links, tutorials or advice are welcome!

From the comments i got that you want to display a popup when an item is clicked but on that position.
Following code example will help. When you click on text View, it will show a popup at position where we have text View in the view
Hoping that will help.
textView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN){
// textView.setText("Touch coordinates : " +
// String.valueOf(event.getX()) + "x" + String.valueOf(event.getY()));
showDialog(event.getX(),event.getY());
}
return true;
}
});
}
public void showDialog(float x, float y)
{
Dialog dialog;
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
dialog = builder.create();
dialog.setTitle("my dialog");
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams wmlp = dialog.getWindow().getAttributes();
//wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = (int) x; //x position
wmlp.y = (int) y; //y position
dialog.show();
}
What i got, the popup is in the middle because the text View is also in the middle

How to dismiss a pop_up window when clicking outside?

I want to know how to close a pop_up window once the user clicks outside it, I had a look at PopupWindow - Dismiss when clicked outside but without any luck, and I tried that code:
pw.setBackgroundDrawable(null);
pw.setOutsideTouchable(true);
pw.setTouchInterceptor(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_OUTSIDE)
{
pw.dismiss();
return true;
}
return false;
}
});

Try this out.Hope it works :)
solution 1:
popupWindow.setFocusable(true);
popupWindow.update();
If this dont work.Then you can try this out.
solution 2:
You can use dialog.setCanceledOnTouchOutside(true); which will close the dialog if you touch outside of the dialog.
Something like,
Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true);
Or if your Dialog in non-model then,
1 - Set the flag-FLAG_NOT_TOUCH_MODAL for your dialog's window attribute
Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
2 - Add another flag to windows properties,, FLAG_WATCH_OUTSIDE_TOUCH - this one is for dialog to receive touch event outside its visible region.
3 - Override onTouchEvent() of dialog and check for action type. if the action type is 'MotionEvent.ACTION_OUTSIDE' means, user is interacting outside the dialog region. So in this case, you can dimiss your dialog or decide what you wanted to perform. view plainprint?
public boolean onTouchEvent(MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
System.out.println("TOuch outside the dialog ******************** ");
this.dismiss();
}
return false;
}

Ok so fixed in the end.
First made the main layout which the popup sits on a relative layout. Then placed a full screen blank layout on top which I made invisible and transparent.
Then show when the popup is shown, set the full screen panel visible with setVisibility(View.VISIBLE); and hide when popup is hidden with setVisibility(View.GONE);
Also need to return true from an on touch listener for the layout with (To stop touch events passing back to the main layout):
blocker.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
And give the popup window the properties:
setTouchable(true);
setOutsideTouchable(false);
Cheers

you should'nt set the BackgroundDrawable to null, because that kills the OnTouchListener ;
you should replace pw.setBackgroundDrawable(null); by pw.setBackgroundDrawable(new BitmapDrawable())

Better use a dialog Fragment for the same. It is made for the popup functionality and closes by default on pressing outside the dialog Fragment or using the hard back button.

Display and Hide alternatively a dialog on touching anywhere on screen in android

I am developing a small app wherein a dialog must popup when the user touches anywhere on the screen and if the dialog is already being displayed then on clicking anywhere outside the dialog box it must disappear. Someone plz give suggestions as to how to go about doing this.

This is possibly duplicate of link
if you want to hide dialog box after touch event then
Dialog dialog = new Dialog(context);
dialog.setCanceledOnTouchOutside(true);
and by overriding the onTouch listener as
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
dialog.dismiss();
}
return false;
}

How to dismiss the dialog with click on outside of the dialog?

I have implemented a custom dialog for my application. I want to implement that when the user clicks outside the dialog, the dialog will be dismissed.
What do I have to do for this?

You can use dialog.setCanceledOnTouchOutside(true); which will close the dialog if you touch outside of the dialog.
Something like,
Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true);
Or if your Dialog in non-model then,
1 - Set the flag-FLAG_NOT_TOUCH_MODAL for your dialog's window attribute
Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
2 - Add another flag to windows properties,, FLAG_WATCH_OUTSIDE_TOUCH - this one is for dialog to receive touch event outside its visible region.
3 - Override onTouchEvent() of dialog and check for action type. if the action type is
'MotionEvent.ACTION_OUTSIDE' means, user is interacting outside the dialog region. So in this case, you can dimiss your dialog or decide what you wanted to perform.
view plainprint?
public boolean onTouchEvent(MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
System.out.println("TOuch outside the dialog ******************** ");
this.dismiss();
}
return false;
}
For more info look at How to dismiss a custom dialog based on touch points? and
How to dismiss your non-modal dialog, when touched outside dialog region

Simply use
dialog.setCanceledOnTouchOutside(true);

You can use this implementation of onTouchEvent. It prevent from reacting underneath activity to the touch event (as mentioned howettl).
#Override
public boolean onTouchEvent ( MotionEvent event ) {
// I only care if the event is an UP action
if ( event.getAction () == MotionEvent.ACTION_UP ) {
// create a rect for storing the window rect
Rect r = new Rect ( 0, 0, 0, 0 );
// retrieve the windows rect
this.getWindow ().getDecorView ().getHitRect ( r );
// check if the event position is inside the window rect
boolean intersects = r.contains ( (int) event.getX (), (int) event.getY () );
// if the event is not inside then we can close the activity
if ( !intersects ) {
// close the activity
this.finish ();
// notify that we consumed this event
return true;
}
}
// let the system handle the event
return super.onTouchEvent ( event );
}
Source: http://blog.twimager.com/2010/08/closing-activity-by-touching-outside.html

Or, if you're customizing the dialog using a theme defined in your style xml, put this line in your theme:
<item name="android:windowCloseOnTouchOutside">true</item>

This method should completely avoid activities below the grey area retrieving click events.
Remove this line if you have it:
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
Put this on your activity created
getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
then override the touch event with this
#Override
public boolean onTouchEvent(MotionEvent ev)
{
if(MotionEvent.ACTION_DOWN == ev.getAction())
{
Rect dialogBounds = new Rect();
getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
// You have clicked the grey area
displayYourDialog();
return false; // stop activity closing
}
}
// Touch events inside are fine.
return super.onTouchEvent(ev);
}

dialog.setCanceledOnTouchOutside(true);
to close dialog on touch outside.
And if you don't want to close on touch outside, use the code below:
dialog.setCanceledOnTouchOutside(false);

You can try this :-
AlterDialog alterdialog;
alertDialog.setCanceledOnTouchOutside(true);
or
alertDialog.setCancelable(true);
And if you have a AlterDialog.Builder Then you can try this:-
alertDialogBuilder.setCancelable(true);

This code is use for when use click on dialogbox that time hidesoftinput and when user click outer side of dialogbox that time both softinput and dialogbox are close.
dialog = new Dialog(act) {
#Override
public boolean onTouchEvent(MotionEvent event) {
// Tap anywhere to close dialog.
Rect dialogBounds = new Rect();
getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) event.getX(),
(int) event.getY())) {
// You have clicked the grey area
InputMethodManager inputMethodManager = (InputMethodManager) act
.getSystemService(act.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(dialog
.getCurrentFocus().getWindowToken(), 0);
dialog.dismiss();
// stop activity closing
} else {
InputMethodManager inputMethodManager = (InputMethodManager) act
.getSystemService(act.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(dialog
.getCurrentFocus().getWindowToken(), 0);
}
return true;
}
};

Another solution, this code was taken from android source code of Window
You should just add these Two methods to your dialog source code.
#Override
public boolean onTouchEvent(MotionEvent event) {
if (isShowing() && (event.getAction() == MotionEvent.ACTION_DOWN
&& isOutOfBounds(getContext(), event) && getWindow().peekDecorView() != null)) {
hide();
}
return false;
}
private boolean isOutOfBounds(Context context, MotionEvent event) {
final int x = (int) event.getX();
final int y = (int) event.getY();
final int slop = ViewConfiguration.get(context).getScaledWindowTouchSlop();
final View decorView = getWindow().getDecorView();
return (x < -slop) || (y < -slop)
|| (x > (decorView.getWidth()+slop))
|| (y > (decorView.getHeight()+slop));
}
This solution doesnt have this problem :
This works great except that the activity underneath also reacts to the touch event. Is there some way to prevent this? – howettl

Following has worked for me:
myDialog.setCanceledOnTouchOutside(true);

Call dialog.setCancelable(false); from your activity/fragment.

You can make a background occupying all the screen size transparent and listen to the onClick event to dismiss it.

I tried some answers still I faced a problem like when I press outside the dialog dialog was hiding but a dimmed view was showing, and pressing again would go to the parent activity. But actually I wanted to go the parent activity after first click.
So what I did was
dialog.setOnCancelListener(this);
and changed my activity to implement DialogInterface.OnCancelListener with
#Override
public void onCancel(DialogInterface dialog) {
finish();
}
And boom, it worked.

Here is the code
dialog.getWindow().getDecorView().setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent ev) {
if(MotionEvent.ACTION_DOWN == ev.getAction())
{
Rect dialogBounds = new Rect();
dialog. getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
// You have clicked the grey area
UiUtils.hideKeyboard2(getActivity());
return false; // stop activity closing
}
}
getActivity().dispatchTouchEvent(ev);
return false;
}
});
Try this one . you can hide the keyboard when you touch outside

Android: Close dialog window on touch

I'd like to close a dialog window in my android app by simply touching the screen.. is this possible? If so, how?
I've looked into setting some "onClickEven" on the dialog, but it doesnt exist.
How would this be possible?

You can use dialog.setCanceledOnTouchOutside(true); which will close the dialog if you touch u=outside the dialog.

If your dialog contains any view try to get the touch events in that view and dismiss your dialog when user touch on that view. For example if your dialog has any Image then your code should be like this.
Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.mylayout);
//create a layout with imageview
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

Dialog dialog = new Dialog(context)
{
public boolean dispatchTouchEvent(MotionEvent event)
{
dialog.dismiss();
return false;
}
};
And you are done!

You can extend Dialog class and override dispatchTouchEvent() method.
EDIT: Also you can implement Window.Callback interface and set it as dialog's window callback using dialog.getWindow().setCallback(). This implementation should call corresponding dialog's methods or handle events in its own way.

If someone still searching for a solution to dismiss a Dialog by
onTouch Event, here is a snippet of code:
public void onClick(View v) {
AlertDialog dialog = new AlertDialog(MyActivity.this){
#Override
public boolean dispatchTouchEvent(MotionEvent event)
{
dismiss();
return false;
}
};
dialog.setIcon(R.drawable.MyIcon);
dialog.setTitle("MyTitle");
dialog.setMessage("MyMessage");
dialog.setCanceledOnTouchOutside(true);
dialog.show();
}
