setOnClickListeners for dynamic created Checkboxes

I'm facing a problem while trying to create Checkboxes Dynamic in my application. The design works fine, and I'm able to create as many Checkboxes as i want. The Checkboxes are put into a TableRow together with a TextView so that the text is at left side of the checkbox. But my problem is, that in my activity i can get the "status" of the checkbox, whether it's checked or not. I use the inflater to create my Checkboxes. The xml for the checkboxes:

<TableRow xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/TableRow" android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView android:paddingLeft="20dip" android:id="@+id/tv_effect" android:gravity="left" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:textColor="#000" android:textSize="18dip" android:layout_width="wrap_content"></TextView>
<CheckBox android:id="@+id/cb_effect" android:layout_height="wrap_content" android:text="" android:layout_gravity="right" android:layout_width="wrap_content"></CheckBox>

The function i call to create a new tablerow containing a textview and a checkbox:

    public void layoutMakeSpeakerEffect(String effectName,int effectNumber)
{
    LayoutInflater linflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View myViewSp = linflater.inflate(R.layout.speaker_settings, null);

    final TextView tv_effect = (TextView) myViewSp.findViewById(R.id.tv_effect);
    tv_effect.setId(effectNumber);
    tv_effect.setText(effectName);

    final CheckBox cb_effect = (CheckBox) myViewSp.findViewById(R.id.cb_effect);
    cb_effect.setId(effectNumber);
    cb_effect.setText("");

    cb_effect.setOnClickListener(new OnClickListener() {
          @Override
          public void onClick(View v) { 
              if(cb_effect.isChecked())
              {
                  Toast toast = Toast.makeText(getApplicationContext(), ""+tv_effect.getText()+": ON", Toast.LENGTH_SHORT);
                  toast.show();
              }
              else
              {
                  Toast toast = Toast.makeText(getApplicationContext(), ""+tv_effect.getText()+": OFF", Toast.LENGTH_SHORT);
                  toast.show(); 
              }
          }
    });

    tl_speakerSettings.addView(myViewSp);   
}

And as mentioned, the design works fine. But how am I able to outside this function to get the "status" off the checkbox? And i also need a function that could clear the checkboxes status, and another function that could enable and disable the checkboxes?

I can't seem to figure this problem out by myself.

My only idea, is to make something that checks the "cb_effects" ID and afterwards checks the status of the desired checkbox.

You can make use of a global integer array that will contain as many elements as there are rows in table. Set the value of the element to 1 if checkbox is checked and 0 for unchecked. By finding which element is having 1 you can fing which of the checkboxes are checked. Hope this works for you.

Use setOnCheckedChangeListener instead. It will fire the onCheckedChanged(CompoundButton buttonView, boolean isChecked) method, where you can now the state of the checkbox reading the isChecked variable.
