Fragment not showing up and breaks other buttons on Layout
- by Devin Crane
I'm learning how to use Fragments, and trying to add a fragment tag_button.xml at runtime to a FrameLayout tagFragmentContainer deep within another layout, deepLayout.xml. I get no errors, but the fragment doesn't show up.
When I make its container visible, I can see a small sliver of layout between the other elements already existing, but then it disappears after onCreateView(), and all the remaining buttons are broken, which is even more confusing to me.
tag_button.xml is just a regular layout file with some text and a button.
tagFragmentContainer, within a LinearLayout in the middle of a large layout file, deepLayout.xml:
<LinearLayout
android:id="@+id/tagButtonsLayout"
android:layout_marginBottom="10dip"
android:visibility="gone"
style="@style/Form">
<FrameLayout
android:id="@+id/tagFragmentContainer"
android:layout_marginBottom="10dip"
style="@style/Form">
</FrameLayout>
</LinearLayout>
In deepLayoutActivity, I make visible tagButtonsLayout and start TagButtonActivity:
final LinearLayout anotherlm = (LinearLayout) findViewById(R.id.tagButtonsLayout);
anotherlm.setVisibility(View.VISIBLE);
Intent i = new Intent (this, TagButtonActivity.class);
startActivity(i);
TagButtonActivity is as follows:
public class TagButtonActivity extends FragmentActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.action_expense);
if (savedInstanceState != null)
return;
TagButtonFragment firstFragment = new TagButtonFragment();
getSupportFragmentManager().beginTransaction().add(R.id.tagFragmentContainer,
firstFragment, "tagOne").commit();
}
}
TagButtonFragment:
public class TagButtonFragment extends Fragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState)
{
// Inflate the layout for this fragment
return inflater.inflate(R.layout.tag_button, container, false);
}
}
tag_button.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="@style/Form">
<TextView
android:id="@+id/tag_button_header"
style="@style/FieldHeader"
android:text="example text"/>
<RelativeLayout
android:id="@+id/tag_button_block"
android:layout_width="match_parent"
android:layout_marginLeft="2dip"
android:layout_marginTop="3dip"
android:layout_marginBottom="3dip"
android:layout_marginRight="2dip"
android:layout_height="43dip"
android:clickable="true"
android:background="@drawable/row_spinner_selector">
<ImageView
android:id="@+id/question_arrow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="@drawable/arrow_right"/>
<TextView
android:id="@+id/tag_question_text"
android:layout_toLeftOf="@id/question_arrow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_centerVertical="true"
android:textColor="@android:color/black"
android:singleLine="true"
android:ellipsize="end"
android:textSize="15sp"
android:text="@string/not_selected"/>
</RelativeLayout>
</LinearLayout>
I would certainly appreciate any help in figuring this out from someone who knows fragments better than me!
Thanks!
