我想在ExpandableList中将不同的子项添加到不同的子项中。
我的MainActivity.java : -
public class MainActivity extends AppCompatActivity {
//private static String TAG = MainActivity.class.getSimpleName();
private Toolbar mToolbar;
ExpandableListAdapter listAdapter;
ExpandableListView expListView;
List<String> listDataHeader;
int arraylistvalue = 0;
ArrayList<String> arraylist1,arraylist2,arraylist3,arrayList4,arrayList5;
int cnt = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
arraylist1 = new ArrayList<String>();
arraylist2 = new ArrayList<String>();
arraylist3 = new ArrayList<String>();
arrayList4 = new ArrayList<String>();
arrayList5 = new ArrayList<String>();
new ProductsAsynTask().execute("http://opencart.codeniques.com/shopping/?route=feed/web_api/menu&key=test123$");
}
public class ProductsAsynTask extends AsyncTask<String,Void,Void>{
ProgressDialog dialog;
protected void onPreExecute(){
super.onPreExecute();
Log.d("In onPreExceute","");
dialog = new ProgressDialog(MainActivity.this);
dialog.setMessage("Loading, Please wait");
dialog.setTitle("Connecting server");
dialog.show();
dialog.setCancelable(false);
}
protected Void doInBackground(String... param){
try{
Log.d("In doInBackground","");
HttpClient client= new DefaultHttpClient();
HttpPost post = new HttpPost(param[0]);
HttpResponse response = client.execute(post);
int status = response.getStatusLine().getStatusCode();
if(status == 200){
Log.d("Status",""+status);
HttpEntity entity = response.getEntity();
String data = EntityUtils.toString(entity);
JSONObject jsonObject = new JSONObject(data);
JSONArray jArray = jsonObject.getJSONArray("categories");
for(int i = 0;i < jArray.length();i++){
cnt++;
Log.d("value of array",jArray.length()+"");
Log.d("Value of i",""+i);
JSONObject jsonObject1 = jArray.getJSONObject(i);
arraylist1.add(jsonObject1.getString("name"));
//data1 = jsonObject1.getString("name");
// Log.d("hello ",data1);
JSONArray jsonArray = jsonObject1.getJSONArray("children");
// JSONObject jsonObject2 = jsonObject1.getJSONObject("children");
for(int j=0;j<jsonArray.length();j++){
JSONObject jsonObject2 = jsonArray.getJSONObject(j);
arraylist2.add(jsonObject2.getString("name"));
// data2 = jsonObject2.getString("name");
JSONArray jsonArray1 = jsonObject2.getJSONArray("children_lv3");
for(int k=0;k<jsonArray1.length();k++){
JSONObject jsonObject3 = jsonArray1.getJSONObject(k);
arraylist3.add(jsonObject3.getString("name"));
arrayList4.add(jsonObject3.getString("href"));
/* data3 = jsonObject3.getString("name");
data4 = jsonObject3.getString("href"); */
}
arrayList5.add(jsonObject2.getString("href"));
// data5 = jsonObject2.getString("href");
}
}
}
}catch(IOException e){
Log.e("Error IOException :",e.getMessage());
}catch (JSONException e){
Log.e("Error JSONException",e.getMessage());
}
return null;
}
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
dialog.dismiss();
expListView = (ExpandableListView) findViewById(R.id.lvExp);
expListView.setAdapter(new ParentLevel());

我的activity.xml在这里: -
<android.support.v4.widget.DrawerLayout

我也想在工具栏下面的抽屉。我是android开发的新手请帮助我提前谢谢
