Android inflate view using an existing view object
I have a custom view that I would like to create from a resource template. My custom view constructor accepts additional parameters that are set as additional info for the custom view.
Problem is when I inflate the view I get a view object that is not subclassed from from custom view since the inflate method is static and returns a generic new view instead of an instance of my custom view.
Would I am looking for is a way to inflate the view by passing it my custom view object reference.
public class MLBalloonOverlayView extends View { MiscInfo mMiscInfo; public MLBalloonOverlayView(Context context, MiscInfo miscInfo) { super(context); mMiscInfo = miscInfo; } public View create(final int resource, final OverlayItem item, MapView mapView, final int markerID) { ViewGroup viewGroup = null; View balloon = View.inflate(getContext(), resource, viewGroup); // I want to return this object so later I can use its mMiscInfo //return this; return balloon; } }
将它膨胀在你的物体上。
public View create(final int resource, final OverlayItem item,
MapView mapView, final int markerID) {
LayoutInflater.from(getContext()).inflate(resource, this, true);
return this;
}
After looking at code at https://github.com/galex/android-mapviewballoons I was able to update my code accordingly. The idea being you create a layout from the resource and then you add the inflated view to the instance of a class that extends a layout (as Marcos suggested above).
public class MLBalloonOverlayView extends FrameLayout {
public MLBalloonOverlayView(Context context, final OverlayItem overlayItem) {
super(context);
mOverlayItem = overlayItem;
}
public void create(final int resource, MapView mapView, final int markerID) {
// inflate resource into this object
TableLayout layout = new TableLayout(getContext());
LayoutInflater.from(getContext()).inflate(resource, layout);
TableLayout.LayoutParams params = new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.NO_GRAVITY;
this.addView(layout, params);
}
}
