android - 自动完成机器人

Question

我如何获得自动完成选择的对象的绝对位置。当我使用 arg2 检索自动完成下拉列表中的相对位置。我想要所选对象在我的原始列表中的位置。

我的代码:

        AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_friends);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, friendsListNameOrder);
        textView.setAdapter(adapter);

        textView.setOnItemClickListener(new OnItemClickListener() {

        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            friendsListNameOrder.get(arg2);

            }

可能没有你希望的那么优雅:

    final String[] COUNTRIES = new String[] { "Belgium", "France", "Italy",
            "Germany", "Spain" };

    final AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.AutoCompleteTextView01);
    final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            R.layout.log_item, COUNTRIES);

    textView.setAdapter(adapter);

    textView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            String s = ((TextView) arg1).getText().toString();
            Log.e("Test", s + " position: "
                    + getArrayIndex(COUNTRIES, s));
        }
    });

其中 getArrayIndex 是:

public final int getArrayIndex(String[] myArray, String myObject) {
    int ArraySize = Array.getLength(myArray);// get the size of the array
    for (int i = 0; i < ArraySize; i++) {
        if (myArray[i].equals(myObject)) {
            return (i);
        }
    }
    return (-1);// didn't find what I was looking for
}
