如何在表格中使用动态创建的复选框

Question

my code above creates a table with checkboxes and textviews inside. the count and the values comes from a MySQL database over php-json. It works all fine. Problem: In the onClickSenden function, I want to check step by step every created checkbox unchecked or checked and do some code depending on.

Its not possible to setId(i), coz "i" is an Iterator and not int.

can u help me?

    public void onClickSenden (View view) {


    }


}

Answer 1

CheckBox cb = new CheckBox(this);
cb.setOnClickListener(this);

Set checkbox id or a tag while creating it.

cb.setTag(someIdentifier);

then use the method

@Override 
public void onClick(View v) {
                 if (v.getTag.equals(someIdentifier)){
                    //do stuff here
                  }    
                }
