Issue
I'm using an AutoCompleteTextView to suggest user some words from my sqlite db as they type the input string to search.
I try to make the suggestion look friendly by using simple_list_item_2, here's my code:
package com.suit.kamus;
import android.app.Activity;
import android.database.Cursor;
import android.database.MatrixCursor;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Button;
import android.widget.SimpleCursorAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.AdapterView.OnItemClickListener;
public class SuitAuto extends Activity implements TextWatcher{
AutoCompleteTextView auto; TextView result;
Button search; Button add; Spinner chooser;
String input; static String selection; String main;
String[] options = {"en to ina", "ina to en"};
SimpleCursorAdapter simple;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
auto = (AutoCompleteTextView)findViewById(R.id.auto);
auto.addTextChangedListener(this);
result = (TextView)findViewById(R.id.result);
chooser = (Spinner)findViewById(R.id.chooser);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, options);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
chooser.setAdapter(adapter);
KamusDbAdapter dbHelper = new KamusDbAdapter(getApplicationContext());
dbHelper.open();
String status = dbHelper.getstatedb();
selection = status;
dbHelper.close();
if (selection.equalsIgnoreCase("en")){
chooser.setSelection(0);
} else {chooser.setSelection(1);}
Log.d("statelang", selection);
add = (Button)findViewById(R.id.add);
add.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
startAdding(main);
}
});
chooser.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
if (chooser.getSelectedItemId() == 0){
selection = "en";
select();
updateDb();
}else{
selection = "ina";
select();
updateDb();
}
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
auto.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
main = auto.getText().toString();
//Log.v("CURSOR",finish);
result.setText("");
auto.setText("");
}
});
}
public void startAdding(String dWord) {
// TODO Auto-generated method stub
KamusDbAdapter adding = new KamusDbAdapter(getApplicationContext());
adding.open();
adding.Favorite(dWord);
adding.close();
}
protected void updateDb() {
// TODO Auto-generated method stub
KamusDbAdapter save = new KamusDbAdapter(getApplicationContext());
save.open();
save.updatestatedb(selection);
save.close();
}
public static String select() {
// TODO Auto-generated method stub
Log.v("STRING",selection);
return selection;
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
input = auto.getText().toString();
KamusDbAdapter x = new KamusDbAdapter(getApplicationContext());
x.open();
Cursor cur = x.getCall(input, selection);
//getCall is in KamusDbAdapter class, it used to return result cursor from sqlite db
//i use rawQuery "SELECT * FROM en_to_ina WHERE word LIKE 'input%'"
x.close();
String[] displayFields = new String[] {"word", "meaning"};
int[] displayViews = new int[] { android.R.id.text1,android.R.id.text2 };
simple = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_2, cur,displayFields, displayViews);
auto.setAdapter(simple);
}
}
I got a problem with retrieving the string from clicked item. It is in:
auto.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
main = auto.getText().toString();
//Log.v("CURSOR",finish);
result.setText("");
auto.setText("");
}
});
I need both strings from word and meaning fields. Any response would be great...
Solution
You need to use http://developer.android.com/reference/android/widget/CursorAdapter.html#getItem(int).
Cursor cursor = (Cursor) simple.getItem(position);
// retrieve the data from the cursor
