javascript - 从 ListView 调用 (OnitemClick)

Question

我想尝试从 ListView 进行调用(将“Toast”更改为直接调用 ListView)。

希望大家帮帮我。

ContactListActiviy.java

        filterList = new ArrayList<ContactItemInterface>();
        contactList = ExampleDataSource.getSampleContactList();

        ExampleContactAdapter adapter = new ExampleContactAdapter(this, R.layout.example_contact_item, contactList);

        listview = (ExampleContactListView) this.findViewById(R.id.listview);
        listview.setFastScrollEnabled(true);
        listview.setAdapter(adapter);

        // use this to process individual clicks

                    Toast.makeText(ContactListActivity.this, "User image is clicked ( " + searchList.get(position).getItemForIndex()  + ")", Toast.LENGTH_SHORT).show();

        //My Trial to Add Call

                //Intent callIntent = new Intent(Intent.ACTION_CALL);
                //callIntent.setData(Uri.parse(phone_no));
                //callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
                //startActivity(callIntent);
            //}
       // });

        //END Trial


        searchBox = (EditText) findViewById(R.id.input_search_query);
        searchBox.addTextChangedListener(this);
    }

    @Override
    public void afterTextChanged(Editable s) {


        searchString = searchBox.getText().toString().trim().toUpperCase();

        if(curSearchTask!=null && curSearchTask.getStatus() != AsyncTask.Status.FINISHED)
        {
            try{
                curSearchTask.cancel(true);
            }
            catch(Exception e){
                Log.i(TAG, "Fail to cancel running search task");
            }

        }
        curSearchTask = new SearchListTask();
        curSearchTask.execute(searchString); // put it in a task so that ui is not freeze
    }


    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // do nothing
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // do nothing
    }

    private class SearchListTask extends AsyncTask<String, Void, String> {



        @Override
        protected String doInBackground(String... params) {
            filterList.clear();

            String keyword = params[0];

            inSearchMode = (keyword.length() > 0);

            if (inSearchMode) {
                // get all the items matching this
                for (ContactItemInterface item : contactList) {
                    ExampleContactItem contact = (ExampleContactItem)item;

                    if ((contact.getNama().toUpperCase().indexOf(keyword) > -1) ) {
                        filterList.add(item);
                    }

                }


            } 
            return null;
        }

        protected void onPostExecute(String result) {

            synchronized(searchLock)
            {

                if(inSearchMode){

                    ExampleContactAdapter adapter = new ExampleContactAdapter(ContactListActivity.this, R.layout.example_contact_item, filterList);
                    adapter.setInSearchMode(true);
                    listview.setInSearchMode(true);
                    listview.setAdapter(adapter);
                }
                else{
                    ExampleContactAdapter adapter = new ExampleContactAdapter(ContactListActivity.this, R.layout.example_contact_item, contactList);
                    adapter.setInSearchMode(false);
                    listview.setInSearchMode(false);
                    listview.setAdapter(adapter);
                }
            }

        }
    }


}

ExampleDataSource.java(顺便说一句，我使用的是“ArrayList”)

package com.ngohung.example.models;

import java.util.ArrayList;
import java.util.List;

import com.ngohung.widget.ContactItemInterface;

public class ExampleDataSource {

    public static List<ContactItemInterface> getSampleContactList(){
         List<ContactItemInterface>  list = new  ArrayList<ContactItemInterface> ();

         list.add(new ExampleContactItem("Polda SULTRA" , "3195040" ,"Sentral PABX jl haluoleo 1" ) );
         list.add(new ExampleContactItem("Polda SULTRA" ,"3195041" , "Sentral PABX jl haluoleo 1") );
         list.add(new ExampleContactItem("Polda SULTRA" ,"3195042" , "Sentral PABX jl haluoleo 1" ) );
         list.add(new ExampleContactItem("Direktorat diklat" , "3190549" , "Sentral PABX jl haluoleo 1") );
         list.add(new ExampleContactItem("Direktorat intelkam" , "3190041", "Jl mayjen di panjaitan 1" ) );
         list.add(new ExampleContactItem("Direktorat samapta" ,"3005114",  "Jl mayjen di panjaitan") );
         list.add(new ExampleContactItem("Direktorat lantas" , "3006112" , "Jl mayjen di panjaitan" ) );
         list.add(new ExampleContactItem("Direktorat pol air" , "3007604", "Jl mayjen di panjaitan" ) );

         return list;
    }


}

添加<uses-permission android:name="android.permission.CALL_PHONE" />对您的 AndroidManifest 文件的许可。

然后在您的列表项点击监听器中启动一个 Activity :

Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:43..." ));
startActivity(intent);

---

更新:

只需在您的项目点击中添加以上代码:

    @Override
    public void onItemClick(AdapterView parent, View v, int position, long id) {
        List<ContactItemInterface> searchList = inSearchMode ? filterList : contactList ;

        float lastTouchX = listview.getScroller().getLastTouchDownEventX();
        if(lastTouchX < 45 && lastTouchX > -1){
            Toast.makeText(ContactListActivity.this, "User image is clicked ( " + searchList.get(position).getItemForIndex()  + ")", Toast.LENGTH_SHORT).show();
        } else
            Toast.makeText(ContactListActivity.this, "Nomor: " + searchList.get(position).getItemForIndex() , Toast.LENGTH_SHORT).show();

            Intent intent = new Intent(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:xxx" ));// replcae "xxx" with the desired number
            startActivity(intent);
        }
   }
