解决方案
如果ListView项不止一个视图点击监听，那么必须实现，而不是列表项单击监听器适配器getView每个视图自定义数据点击监听器（）：
@覆盖
公共查看getView（最终诠释的立场，观点convertView，ViewGroup中父）{
ViewHolder持有人;
如果（convertView == NULL）{
持有人=新ViewHolder（）;
convertView = LayoutInflater.from（上下文）.inflate（R.layout.list_item_interestrecv，NULL）;
holder.btnAccept =（按钮）convertView.findViewById（R.id.btnAccept）;
holder.btnDecline =（按钮）convertView.findViewById（R.id.btnDecline）;
convertView.setTag（保持器）;
}其他{
支架=（ViewHolder）convertView.getTag（）;
}
holder.btnAccept.setOnClickListener（新View.OnClickListener（）{
@覆盖
公共无效的onClick（视图v）{
意向意图=新的意图（getApplicationContext（），InterestDetails.class）;
intent.putExtra（received_detail_id，listData.get（位置）获得（INTEREST_RECEIVEUSER_ID））;
startActivity（意向）;
}
}）;
holder.btnDecline.setOnClickListener（新View.OnClickListener（）{
@覆盖
公共无效的onClick（视图v）{
意向意图=新的意图（getApplicationContext（），InterestDetails.class）;
intent.putExtra（received_detail_id，listData.get（位置）获得（INTEREST_RECEIVEUSER_ID））;

}
}）;
返回convertView;
}
类ViewHolder {
按钮btnAccept;
按钮btnDecline;
}
I am creating one example where I am passing id from one activity to another,in my first activity I have Listview,after click on any item it should redirect to next page,in my other activities same code is working but for this activity after cliking on list,its not intent..
public class InterestAccept extends ListActivity{
private ProgressDialog pDialog;
JSONArray interestreceived=null;
private ListView l;
private ArrayList<HashMap<String,String>> aList;
private static String INTEREST_RECEIVE_URL = "";
private static final String INTEREST_RECEIVE="interestreceived";
private static final String INTEREST_RECEIVEUSER_ID="received_detail_id";
private static final String INTEREST_RECEIVE_NAME="name";
private static final String INTEREST_RECEIVE_PROFILE="profile_id";
private static final String INTEREST_RECEIVE_IMAGE="image";
private static final String INTEREST_RECEIVE_CAST="cast";
private static final String INTEREST_RECEIVE_AGE="age";
private static final String INTEREST_RECEIVE_LOCATION="location";
private CustomAdapterReceive adapter;
private TextView nointrecive;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.list_view);
nointrecive=(TextView)findViewById(R.id.no_intrecv);
String strtexts = getIntent().getStringExtra("id");
System.out.println("<<<<<<<< id : " + strtexts);
INTEREST_RECEIVE_URL = "xxxxxxxx"+strtexts;
//listview=(ListView)findViewById(R.id.list);
//ListView listview = this.getListView();
ListView listview = (ListView)findViewById(android.R.id.list);
new LoadAlbums().execute();
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(getApplicationContext(), InterestDetails.class);
intent.putExtra("received_detail_id", aList.get(position).get(INTEREST_RECEIVEUSER_ID));
startActivity(intent);
}
class LoadAlbums extends AsyncTask<String, String, ArrayList<HashMap<String,String>>> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(InterestAccept.this);
pDialog.setMessage("Loading...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected ArrayList<HashMap<String,String>> doInBackground(String... args) {
ServiceHandler sh = new ServiceHandler();
// Making a request to url and getting response
ArrayList<HashMap<String,String>> data = new ArrayList<HashMap<String, String>>();
String jsonStr = sh.makeServiceCall(INTEREST_RECEIVE_URL, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
interestreceived = jsonObj.getJSONArray(INTEREST_RECEIVE);
// looping through All Contacts
for (int i = 0; i < interestreceived.length(); i++) {
JSONObject c = interestreceived.getJSONObject(i);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(INTEREST_RECEIVEUSER_ID, c.getString(INTEREST_RECEIVEUSER_ID));
map.put(INTEREST_RECEIVE_NAME,c.getString(INTEREST_RECEIVE_NAME));
map.put(INTEREST_RECEIVE_PROFILE, c.getString(INTEREST_RECEIVE_PROFILE));
map.put(INTEREST_RECEIVE_IMAGE, c.getString(INTEREST_RECEIVE_IMAGE));
//map.put(INTEREST_RECEIVE_CAST, c.getString(INTEREST_RECEIVE_CAST));
map.put(INTEREST_RECEIVE_AGE, c.getString(INTEREST_RECEIVE_AGE)+" years");
map.put(INTEREST_RECEIVE_LOCATION, c.getString(INTEREST_RECEIVE_LOCATION));
// adding HashList to ArrayList
data.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return data;
}
protected void onPostExecute(ArrayList<HashMap<String,String>> result) {
super.onPostExecute(result);
if(interestreceived == null || interestreceived.length() == 0){
// Toast.makeText(getApplicationContext(), "No response", Toast.LENGTH_SHORT).show();
nointrecive.setText(" No Interest Receive ");
}
else
{
nointrecive.setVisibility(View.INVISIBLE);
}
// dismiss the dialog after getting all albums
if (pDialog.isShowing())
pDialog.dismiss();
// updating UI from Background Thread
if(aList == null){
aList = new ArrayList<HashMap<String, String>>();
aList.addAll(result);
adapter = new CustomAdapterReceive(getBaseContext(), result);
setListAdapter(adapter);
}else{
aList.addAll(result);
adapter.notifyDataSetChanged();
}
}
}
}
解决方案
If ListView item more then one view click listener then have to implement each view custom data click listener in adapter getView() instead of list item click listener :
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.list_item_interestrecv, null);
holder.btnAccept = (Button) convertView.findViewById(R.id.btnAccept);
holder.btnDecline = (Button) convertView.findViewById(R.id.btnDecline);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.btnAccept.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), InterestDetails.class);
intent.putExtra("received_detail_id", listData.get(position).get(INTEREST_RECEIVEUSER_ID));
startActivity(intent);
}
});
holder.btnDecline.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), InterestDetails.class);
intent.putExtra("received_detail_id", listData.get(position).get(INTEREST_RECEIVEUSER_ID));
startActivity(intent);
}
});
return convertView;
}
class ViewHolder{
Button btnAccept;
Button btnDecline;
}
