Concerning Android's built-in Java GUI system and the XML config
stuff, I was more going to use the API like the following. Basically
I am going to issue an HTTP POST, receive back a JSON "form", and
dynamically compose the screen. Then when the user does something
(i.e. clicks a button) I will communicate back to the server the event
that occurred. You could almost think of it as a lightweight browser
that allows you to use native Android UI Widgets. Do you know if
anybody else has already gone before me and developed something like
this?
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
// nvps.add(new BasicNameValuePair("screen", "login"));
String result =
connect("http://red.rpg-xml.com/oru11web/orudroid2";, nvps);
try {
JSONObject json = new JSONObject(result);
JSONArray topElems = json.names();
for (int i1 = 0; i1 < topElems.length(); i1++) {
if (topElems.getString(i1).equals(TYP_FORM)) {
JSONObject form =
json.getJSONObject("FORM");
// Create form
sv = new ScrollView(this);
LinearLayout ll = new
LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);
JSONArray fldLst =
form.getJSONArray(TYP_FLDLST);
for (int i2 = 0; i2 < fldLst.length();
i2++) {
JSONObject fld =
fldLst.getJSONObject(i2);
if
(fld.get(TYP).equals(TYP_BTN)) {
UIButton b = new
UIButton(this);
b.setText(fld.getString(VALUE));
b.setOnClickListener(new OnClickListener() {
@Override
public void
onClick(View v) {
processEvent(v);
}
});
b.setAction(fld.getString(ACTION));
ll.addView(b);
} else if
(fld.get(TYP).equals(TYP_TXTFLD)) {
EditText et = new
EditText(this);
et.setText(fld.getString(VALUE));
ll.addView(et);
} else if
(fld.get(TYP).equals(TYP_LBL)) {
TextView tv = new
TextView(this);
tv.setText(fld.getString(VALUE));
ll.addView(tv);
}
}
this.setContentView(sv);
} else {
// Not implemented.
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
