Nel nostro layoutIn nostro layout, possiamo includere uno ScrollView con un LinearLayout verticale (o con un po 'di lavoro di un RelativeLayout). In questi:
<TextView
android:id="@+id/txtvw_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="@string/str_more"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/txtvw_detail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/txtvw_tituloEntreTodos"
android:text="@string/str_details"
android:textAppearance="?android:attr/textAppearanceMedium" />
Infine la nostra attività
view = inflater.inflate(R.layout.f_entretodos, container, false);
info = (TextView) view.findViewById(R.id.txtvw_header);
fullinfo = (TextView) view.findViewById(R.id.txtvw_detail);
info.setText(Html.fromHtml(getString(R.string.str_more)));
fullinfo.setText(Html.fromHtml(getString(R.string.str_detail)));
fullinfo.setVisibility(View.GONE);
info.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (fullinfo.isShown()){
fullinfo.setVisibility(View.GONE);
info.setText(Html.fromHtml(getString(R.string.str_more)));
}else{
fullinfo.setVisibility(View.VISIBLE);
info.setText(Html.fromHtml(getString(R.string.str_less)));
}
}
});

Sì , questo aiuta un po ', poiché implementa ciò che sto cercando, ma speravo fosse una soluzione più semplice di un layout personalizzato ... –
