How to make a new checkbox appear on clicking button in Android

问题

How can I create a new checkbox every time I click a button and how do I hide a check box?

Also, why doesn't checkbox.setVisibility(View.Gone); work the same way textview.setVisibility(View.Gone) worked?

回答1:

LinearLayout my_layout = (LinearLayout)findViewById(R.id.my_layout);
button.setOnClickListener(new onClickListener(){
     void onClick(){
          CheckBox checkBox = new CheckBox(this);
          checkBox.setText(Str_Array[i]);
          my_layout.addView(checkBox);
    }
});

回答2:

Create the checkbox in the layout and set visibility to View.GONE, and when you need set visibility to View.VISIBLE to show the checkbox
