My Android Application cant able to display XML parsed data into ListView.. Its displaying Toast message only.
Help me, Your help would be appreciated.
My Code Is : .java
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ll = (LinearLayout) findViewById(R.id.layout);
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if(ni.isAvailable())
{
if(!(ni.isConnected()))
{
Toast.makeText(getApplicationContext(), "No WIFI Connected...", Toast.LENGTH_LONG).show();
}
}
else
{
/*ni = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if(ni.isAvailable())
{
if(ni.isConnected())
{
}
}*/
b = (Button) findViewById(R.id.button1);
//intent = new Intent(getApplicationContext(), display.class);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ed1 = (EditText) findViewById(R.id.what);
ed2 = (EditText) findViewById(R.id.where);
String what = ed1.getText().toString();
String where = ed2.getText().toString();
if(what.equals("") || where.equals(""))
{
Toast.makeText(getApplicationContext(), "Please, Enter Some Missing Value.", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(),"Wait... Searching.....", Toast.LENGTH_LONG).show();
try {
URL text = new URL("My_URL");
XmlPullParserFactory xppf=XmlPullParserFactory.newInstance();
XmlPullParser xpp=xppf.newPullParser();
xpp.setInput(text.openStream(),null);
int pe =xpp.getEventType();
boolean status=false;
while(pe!=XmlPullParser.END_DOCUMENT)
{
switch(pe)
{
case XmlPullParser.START_TAG:
String tag=xpp.getName();
if(tag.equals("status"))
{
status=true;
}
if(tag.equals("name"))
{
nameTag=true;
}
if(tag.equals("formatted_address"))
{
addTag=true;
}
break;
case XmlPullParser.TEXT:
String value;
if(status==true)
{
value=xpp.getText();
if(value.equals("ZERO_RESULTS"))
{
Toast.makeText(getApplicationContext(), "No Results Found for "+ed1.getText().toString(), Toast.LENGTH_LONG).show();
}
}
if(nameTag==true)
{
value=xpp.getText();
newName.add(value);
}
if(addTag==true)
{
value=xpp.getText();
newAdd.add(value);
}
break;
case XmlPullParser.END_TAG:
String txt=xpp.getName();
if(txt.equals("name"))
{
nameTag=false;
}
if(txt.equals("formatted_address"))
{
addTag=false;
}
break;
}//end switch
pe=xpp.next();
}//end while
//ArrayList to String[] for name
String name[] = new String[newName.size()];
name = newName.toArray(name);
//ArrayList to String[] for Address
String add[] = new String[newAdd.size()];
add = newAdd.toArray(add);
Intent i = new Intent(getApplicationContext(), List.class);
i.putExtra("nameTag", name);
i.putExtra("addTag", add);
startActivity(i);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();

XML file:
<?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" android:id="@+id/linear">
<ListView
android:layout_height="wrap_content"
android:id="@+id/listview1"
android:layout_width="fill_parent"/>
</LinearLayout>
when I was learning parsing xml and displaying it in ListView this tutorial helped me a lot, take a look:
