How To Implement Nested Xml Structure Into 2 Listviews?

I am trying to parse an XML file with the following structure: .......

Solution 1:

Create a data object Group.

publicclassGroup {
privateString id;
privateString name;
privateString description;
privateArrayList<String> actions;
publicStringgetId() {
    return id;
}
publicvoidsetId(String id) {
    this.id = id;
}
publicStringgetName() {
    return name;
}
publicvoidsetName(String name) {
    this.name = name;
}
publicStringgetDescription() {
    return description;
}
publicvoidsetDescription(String description) {
    this.description = description;
}
publicArrayList<String> getActions() {
    return actions;
}
publicvoidsetActions(ArrayList<String> actions) {
    this.actions = actions;
}
}

Your activity code will look something like this.

publicclassMainActivityextendsActivityimplementsOnItemClickListener {

private ArrayList<Group> groups;
private ListView list;
private MyAdapter adapter;
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    list = (ListView)findViewById(R.id.my_list);
    list.setAdapter(adapter = newMyAdapter());
    list.setOnItemClickListener(this);
    parseXML();
}


privatevoidparseXML(){
    // TODO: CODE TO PARSE XML
    adapter.notifyDataSetChanged();
}
@OverridepublicbooleanonCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    returntrue;
}


publicclassMyAdapterextendsBaseAdapter{

    @OverridepublicintgetCount() {
        // TODO Auto-generated method stubreturn groups.size();
    }

    @Overridepublic Object getItem(int arg0) {
        // TODO Auto-generated method stubreturn groups.get(0);
    }

    @OverridepubliclonggetItemId(int position) {
        // TODO Auto-generated method stubreturn position;
    }

    @Overridepublic View getView(int position, View convertView, ViewGroup parent) {
        // TODO: Create row view here.// USE groups to create list herereturnnull;
    }

}


@OverridepublicvoidonItemClick(AdapterView<?> listView, View rowView, int position, long column) {
    // TODO Auto-generated method stubGroupclickedGroup= groups.get(position);
    Intentintent=newIntent(this, SecondActivity.class);
    Bundlebundle=newBundle();
    bundle.putStringArrayList("ACTIONS", clickedGroup.getActions());
    intent.putExtra("BUNDLE", bundle);
    startActivity(intent);
}

}

Your second activity will look something like this

publicclassSecondActivityextendsActivity {

private ArrayList<String> actions;
private ListView list;
private ActionAdapter adapter;
@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);

    Intentintent= getIntent();
    Bundlebundle= intent.getBundleExtra("BUNDLE");
    actions = bundle.getStringArrayList("ACTIONS");

    list = (ListView)findViewById(R.id.my_list2);
    list.setAdapter(adapter = newActionAdapter());
}



@OverridepublicbooleanonCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    returntrue;
}


publicclassActionAdapterextendsBaseAdapter{

    @OverridepublicintgetCount() {
        // TODO Auto-generated method stubreturn actions.size();
    }

    @Overridepublic Object getItem(int arg0) {
        // TODO Auto-generated method stubreturn actions.get(0);
    }

    @OverridepubliclonggetItemId(int position) {
        // TODO Auto-generated method stubreturn position;
    }

    @Overridepublic View getView(int position, View convertView, ViewGroup parent) {
        // TODO: Create row view here.// USE actions to create list herereturnnull;
    }

}

}
