Is there a way to disable all the items in a specific layout programmatically?

I have A game to which I recently added a global high score functionality which made a lot of people upset so I want to add the option of disabling it. What I did was this: in my settings activity view, I added the following:

<!-- High Score Tracking -->
 <LinearLayout android:layout_weight="40"
  android:layout_width="fill_parent" android:layout_height="wrap_content"
  android:orientation="vertical" android:padding="5dip">
  <LinearLayout android:layout_width="fill_parent"
   android:layout_height="wrap_content">
   <CheckBox android:text="@string/EnableHighscoreCBText"
    android:id="@+id/EnableHighscoreCB" android:layout_width="fill_parent"
    android:layout_height="wrap_content">
   </CheckBox>
  </LinearLayout>
  <!-- High score specific settings -->
  <LinearLayout android:layout_width="fill_parent"
   android:layout_height="wrap_content" android:orientation="horizontal"
   android:weightSum="100" android:padding="5dip">
   <CheckBox android:text="@string/EnableShareScoresCBText"
    android:id="@+id/EnableShareScoresCB" android:layout_width="fill_parent"
    android:layout_height="wrap_content">
   </CheckBox>

   <TextView android:id="@+id/DefaultPlayerNameTv"
    android:layout_width="wrap_content" android:layout_weight="30"
    android:layout_height="wrap_content" android:text="@string/pDefName"
    android:textSize="18sp">
   </TextView>
   <EditText android:id="@+id/PlayerNameEt"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:text="@string/pNameDefVal" android:layout_weight="70"
    android:textSize="18sp" android:maxLength="20">
   </EditText>
  </LinearLayout>
 </LinearLayout>

What I want to do is to disable the entire "High score specific settings" layout when the user unchecks the enable high score tracking check box. I tried disabling it by setting the setEnabled to false, but that didn't work at all. Should I be using a viewgroup or something? Is there a refresh method I should run to ap开发者_Go百科ply the change?

Add a View.OnClickListener to your CheckBox then pass the View you want to be disabled into the following function...

private void enableDisableView(View view, boolean enabled) {
    view.setEnabled(enabled);

    if ( view instanceof ViewGroup ) {
        ViewGroup group = (ViewGroup)view;

        for ( int idx = 0 ; idx < group.getChildCount() ; idx++ ) {
            enableDisableView(group.getChildAt(idx), enabled);
        }
    }
}

Just control the visiblity parameter for the Layout via setVisibility(). You can switch it between three values: visible, invisible and gone (see the documentation).

I think in your case the most senseful would be to switch between visible and gone.

Apparently the correct way to do it is by using preferences... I'm reading about it now, but I think that's what people should use if they are trying to implement something like that check out the following links for more information on this:
