这是来自contactHandlerDatabase类
public List<Contact> displayAllContact(){
//display all the contact in repertoire
List<Contact> AllContactList= new ArrayList<Contact>();//create the arraylist of contact
SQLiteDatabase db=this.getWritableDatabase();//in writable mode
Cursor cursor=db.rawQuery(SELECT_ALL_QUERY+TABLE_NAME,null);
if(cursor.moveToFirst()){
do{//capture data of all columns in each row
Contact contact=new Contact();
contact.setContactName(cursor.getString(0));
contact.setContactSurname(cursor.getString(1));
contact.setContactTel(Integer.parseInt(cursor.getString(2)));
contact.setContactEmail(cursor.getString(3));
AllContactList.add(contact);//add all column data to list
}while (cursor.moveToNext());
}//end if
return AllContactList;
}
这是来自CallHistory类
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
List<Contact> AllContactList;
switch (requestCode){
case REQ_CODE_SPEECH_INPUT:{
if ((resultCode == RESULT_OK) && (data != null)) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
AllContactList=db.displayAllContact();
**enter code here**
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,R.layout.activity_repertoire,R.id.lblCallHistory,AllContactList);
}//end if
else{
convertToSpeech("Discours incoherent");
}//end else
}//end case
break;
}//end switch
}//end of onActivityResult method
我不知道如何在ArrayAdapter中实现AllContactList，因为它正在请求List作为参数。请帮助
