ok, this should be super simple but it is proving difficult.
In my original layout xml I have 2 buttons that I want to take up
equal space in a LinearLayout
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="10px" android:paddingRight="10px" >
<LinearLayout
android:id="@+id/story_video_layout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:id="@+id/story_video"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Play Video"
/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:id="@+id/story_share"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Share This Story"/>
</LinearLayout>
</LinearLayout>
This works fine...
Now at runtime in the activity there are cases where I want to hide
the first button (share_video) and have the other button centered and
its width set to wrap_content.
I can hide the first button just fine by using the following code,
View videoLayout = findViewById(R.id.story_video_layout);
videoLayout.setVisibility(View.GONE);
cool...
But no matter what I do, I cannot get the second button to center.
When I make the following call just to change the layout of the button
to wrap content I get exceptions being thrown and it crashes.
View storyBtn = findViewById(R.id.story_share);
LayoutParams params = new LayoutParams
(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
storyBtn.setLayoutParams(params);
1. why is it crashing?
2. what is the correct way to get the button to center in the layout
correctly?
Thank you so much for your help...
