How to Disable All Views Inside the Layout

How can I disable all views inside the layout?

Another way is to call setEnabled() on each child (for example if you want to do some extra check on child before disabling)

LinearLayout layout = (LinearLayout) findViewById(R.id.my_layout);
for (int i = 0; i < layout.getChildCount(); i++) {
    View child = layout.getChildAt(i);
    child.setEnabled(false);
}

Disabling all child views inside the layout

Because your layouts are so heavily nested, you need to recursively disable the views. Instead of using your method, try something like this:

private static void disable(ViewGroup layout) {
    layout.setEnabled(false);
    for (int i = 0; i < layout.getChildCount(); i++) {
        View child = layout.getChildAt(i);
        if (child instanceof ViewGroup) {
            disable((ViewGroup) child);
        } else {
            child.setEnabled(false);
        }
    }
}

then call:

disable(content_view);

How to disable all content inside linear layout in android?

You need to do as follows:

LinearLayout myLayout = (LinearLayout) findViewById(R.id.linearLayout1);
for ( int i = 0; i < myLayout.getChildCount();  i++ ){
    View view = myLayout.getChildAt(i);
    view.setEnabled(false); // Or whatever you want to do with the view.
 }

Then create an alert Dialog and then

myLayout.setOnclickListener(new OnClickListener(){

   onClick(){
     dialog.show();
   }
});

Disable all edittext inside linear layout

Where ll is your linearlayout:

    LinearLayout ll = (LinearLayout) findViewById(R.id.myLLid);
    for (View view : ll.getTouchables()){
        if (view instanceof EditText){
            EditText editText = (EditText) view;
            editText.setEnabled(false);
            editText.setFocusable(false);
            editText.setFocusableInTouchMode(false);
        }
    }

How to disable all click events of a layout?

I would create a ViewGroup with all the views that you want to enable/disable at the same time and call setClickable(true/false) to enable/disable clicking.

Disable all items inside linear layout including items inside nested linear layouts

Try this recursive function:

public void disableAllViews(View v){
    v.setEnabled(false);
    if(v instanceof ViewGroup){

    for (int i = 0; i < ((ViewGroup)v).getChildCount();  i++) {
        View view = ((ViewGroup)v).getChildAt(i);
        disableAllViews(view);
    }
    }
}

And call it as

LinearLayout myLayout
    = (LinearLayout)v.findViewById(R.id.addEditSection1);
disableAllViews(myLayout);

How to hide all elements in a Layout in Android at once?

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/imageView3"
        android:layout_alignParentRight="true"

                        Log.d("TAG", "setSingleTapListener");

                        sCounter++;
                        if (sCounter % 2 == 0) {
                            mRlTopOverlayBar.setVisibility(View.GONE);
                            mRlBottomOverlayBar.setVisibility(View.GONE);

Remove all items inside linearlayout

Why you wrote linearLayout.getParent()?

You should call this directly on LinearLayout:

linearLayout.removeAllViews();
