I want to set the height of my Gridview programmatically in my application.
Is there any way to implement that?
I just want to change the gridview height in two particularcases from the code.
EDIT:
<fragment
android:id="@+id/mygridview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dip"
class="com.myapp.android.MyGridViewClass" />
MyGridViewClass extends Fragment where Gridview is populated.
<GridView
android:id="@+id/mygridview_container"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dip"
android:columnWidth="90dp"
android:gravity="center_vertical|center_horizontal"
android:horizontalSpacing="1dp"
android:numColumns="3"
android:scrollbars="vertical"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="5dp" />
In myGridViewClass onViewCreated
, I am inflating the gridview using the code,
gridView = (GridView)getView().findViewById( R.id.mygridview_container);
gridAdapter = new MyCustomAdapter(context, list);
gridView.setAdapter(gridAdapter);
Whenever the view is created I have to check the number of items in the gridview and set the height accordingly.
When I tried setting the layoutParams() for gridview, I got this exception.
android.view.InflateException: Binary XML file line #89: Error inflating class fragment
Where line 89 corresponds to this line in the fragment class="com.myapp.android.MyGridViewClass"
Use this, as you want to retain the current layoutParams
:
ViewGroup.LayoutParams layoutParams = yourGridview.getLayoutParams();
layoutParams.height = 50; //this is in pixels
yourGridview.setLayoutParams(layoutParams);
Edit: If you want to input the height as dp
instead of pixels, translate the dp
amount to pixels:
public static int convertDpToPixels(float dp, Context context){
Resources resources = context.getResources();
return (int) TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP,
dp,
resources.getDisplayMetrics()
);
}
