我怎么知道，有多少个EditText用户添加？

Question

I inflate an EditText and I setId(i++) | static int i = 0;

and this is the code :

 buttonAdd.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View arg0) {




            LayoutInflater layoutInflater =
                    (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            final View addOne = layoutInflater.inflate(R.layout.row, null);
            final EditText textOut = (EditText)addOne.findViewById(R.id.textout);
            Button buttonRemove = (Button)addOne.findViewById(R.id.remove);
            buttonRemove.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    ((LinearLayout) addOne.getParent()).removeView(addOne);


                }
            });

            container.addView(addOne);
                textOut.setId(i++);  }});

so, if I add an EditText, the Id will be 0 and if I add another EditText, the Id will be 1 .. etc

so, the user can select how many EditText he want, right ?

if the user add 3 EditText for example

How can my code knows ?

for example, if I want sum all the values of EditText, and the user add 3 EditTixt

I will do this

( EditText one = (EditText)findViewById(0) ) + ( EditText dodo  =  (EditText)findViewById(1) ) + ( EditText dodo = (EditText)findViewById(2) )

But, if I don't know how many EditTixt the user will add ! what can I do ?

thank you.

Answer 1

int count = 0;
int childcount = container.getChildCount();
for (int i=0; i < childcount; i++){
      View v = container.getChildAt(i);
      if(view.getTag.equals("edittext"){
       count ++;
     }

}

and change this line in your code

final View addOne = layoutInflater.inflate(R.layout.row, null);
  addOne.setTag("edittext");

count return you total edittext added by user

Answer 2

take look on this code it will count edit text for you in your layout container

first you need to making changed in your code like this and it worked with me fine :

 final ViewGroup addOne = (ViewGroup) layoutInflater.inflate(R.layout.test, null);

int count = 0 ; 
    for (int i = 0; i < addOne .getChildCount(); i++) {

        if(addOne .getChildAt(i).getClass().getSimpleName().equals("EditText"))
            count ++ ;
    }
