如何从复选框隐藏和取消隐藏框

Question

I'm a student of android developer. I need to make a project and I've ran into a problem. basically the problem is that i need to make the box of a checkBox disappear and only after pushing a specific button, the box will appear and be clickable. from my searches i've found that when i write:

myCheckBox.setButtonDrawable(new ColorDrawable(Color.TRANSPARENT));

it will disappear and it's good but couldn't find the way to make it appear after that.. thanks a lot. :)

Answer 1

You can achieve that my making the view disappear either by using

myCheckBox.setVisibility(View.GONE);
             (OR)
myCheckBox.setVisibility(View.INVISIBLE);

And again you can make it to appear by

myCheckBox.setVisibility(View.VISIBLE);

Hope this is helpful:)

Answer 2

You need to use

yourCheckBox.setVisibility(View.GONE);

to make that visible again,

yourCheckBox.setVisibility(View.VISIBLE);

Answer 3

You can get the currently assigned drawable with getButtonDrawable() and store it in a field, for example:

class Foo {
  private Drawable oldDrawable;
  private CheckBox myCheckBox;

  public void hideCheckbox() {
    oldDrawable = myCheckBox.getButtonDrawable();
    myCheckBox.setButtonDrawable(new ColorDrawable(Color.TRANSPARENT));
  }

  public void showCheckbox() {
    myCheckBox.setButtonDrawable(oldDrawable);
  }
}
