Hello!
I try to populate a Gallery dynamically with some values put it in
TextViews.
I cannot manage to do that. The code is quite complex.
In main java class i get the Gallery and i set it to a custom adapter.
this.galleryView.setAdapter(new
GalleryAdapter(getApplicationContext(), values));
where values is a ArrayList<String> with names to be put in TextViews
in Gallery.
In GalleryAdapter i have something like this
public View getView(int position, View view, ViewGroup parent) {
View v = null;
if (view == null) {
v =
LayoutInflater.from(this.context).inflate(R.layout.gallery_item,
parent, false);
} else {
v = view;
}
LinearLayout galleryLinearLayout = (LinearLayout)
v.findViewById(R.id.galleryItemLinearLayout);
for (String val : this.values) {
TextView textview = new TextView(this.context);
textview.setText(val);
textview.setTextSize(TypedValue.COMPLEX_UNIT_SP, 30);
textview.setPadding(30, 5, 30, 5);
textview.setTextColor(Color.WHITE);
galleryLinearLayout.addView(textview);
}
return v;
}
and gallery_item xml file is like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/galleryItemLinearLayout">
</LinearLayout>
</LinearLayout>
The behavior is not the expected one. Is not displays all values and
also the scroll acts strange
Can someone tell me what i do wrong or the guide me to a better
example.
Thanks
