Question

Im hiding a button from within a handler (This is after i have made it Visible in another state of the app). The handler receives a message from a running thread and then updates the GUI.

The problem is that nearby (not all) buttons and textviews are also dissappearing from the screen.. Im using Relative Layout.

Layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget54"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<Button
    android:id="@+id/btnFold"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:text="Fold" 
    android:visibility="invisible"/ >

<Button
    android:id="@+id/btnRaise"
    android:layout_width="wrap_content"

<TextView
    android:id="@+id/txtChipAmount"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

    android:layout_toLeftOf="@+id/btnCall"
    android:layout_toRightOf="@+id/txtHand1"
    android:text="103360" />

Does anyone know what could be causing the problem?

btnFold = (Button)findViewById(R.id.btnFold);
btnFold.setVisibility(View.GONE);

Answer 1

Now that I see your full xml – when you set a View to GONE, views that are set relative to it (layout_toLeftOf, layout_above) are put in the top left (or wherever their other constraints put them, e.g. a view that is toLeftOf and aligned parent bottom will go to the bottom left of screen now (it has nothing to be toLeftOf and is on bottom). I’d recommend setting View.INVISIBLE if you just want to hide a View, not View.GONE unless you have a specific reason for that?
