如何在android上为多个复选框动态添加动作？

Question

In my project rows are added dynamically to the table depending on selected items from database. This table contains a column with checkbox

How can I set action for each checkbox that are added dynamically ? The table looks like this

  column1 column2 column3 id1 data1 checkbox1 id2 data2 checkbox2 . . . . . .idn datan checkboxn 

Then I want to set action for all selected checkbox and the no of checkbox not defined that changes on every activity..

  CheckBox  check[i]= new CheckBox(this); 

    check[i].setOnClickListener(new OnClickListener()
    {
        public void onClick(View v)
        {
            //code
        }
    });

Is it possible to use this logic?

Answer 1

What you can do is:

1. As you create each checkbox, give it a unique tag by using setTag(Object tag) method.

2. Set the same OnClickListener for each checkbox.

3. Inside onClick(View v) method, get the tag by using v.getTag() . This way you will know which checkbox was clicked.

Answer 2

I would say yes.

FrameLayout yourlayout = (FrameLayout) findViewById(R.id.container);
    CheckBox[] check = new CheckBox[10];
    check[0] = new CheckBox(this);

    yourlayout.addView(check[0]);

    check[0].setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            Toast.makeText(getApplicationContext(), "Hi, this is working fine", Toast.LENGTH_SHORT).show();
        }
    });

I don't know what kind of layout you are using, but this example works for me.

Edit: as said above, setting a tag is a nice way to know what checkbox was pressed.
