I am trying to change the layout width of two cardview element between MATCH_PARENT and 0dp. When I simulate the scenario via xml changes, it is correct, however, when I do it programmatically, it is not rendering as expected.
xml
<LinearLayout
android:id="@+id/lDates"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="@dimen/card_margins"
android:layout_marginEnd="@dimen/card_margins"
android:layout_below="@id/lnrButtons"
android:orientation="horizontal">
<android.support.v7.widget.CardView
android:id="@+id/cardSectionA"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:cardElevation="0dp"
android:layout_marginEnd="@dimen/card_margins"
android:layout_marginBottom="@dimen/card_margins"
app:cardCornerRadius="4dp"
android:layout_weight="1">
<TextView
android:id="@+id/textLabelA"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="@string/sample_value"/>
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView
android:id="@+id/cardSectionB"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:cardElevation="0dp"
android:layout_marginEnd="@dimen/card_margins"
android:layout_marginBottom="@dimen/card_margins"
app:cardCornerRadius="4dp"
android:layout_weight="1">
<TextView
android:id="@+id/textLabelB"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/sample_value"/>
</android.support.v7.widget.CardView>
</LinearLayout>
java
//as-is scenario; cardSectionA and cardSectionB should be shown
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
cardSectionA.getLayoutParams().width,
LinearLayout.LayoutParams.WRAP_CONTENT
);
cardSectionA.setLayoutParams(params);
cardSectionB.setLayoutParams(params);
//should only show cardSectionA scenario
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
cardSectionA.setLayoutParams(params);
Thanks a lot.
Figured it out. To behave as expected, the margin and layout weight must also be set.
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
int margin = 10;
params.setMargins(margin, margin, margin, margin);
params.weight = 1;
cardSectionA.setLayoutParams(params);
