嗨，我制作了一个 android 应用程序，其中我将所有地址簿联系人加载到列表中，并在其上方放置了一个编辑文本，如果我输入任何字母，那么它应该给我列表中与该字母相关的所有值，我尝试过下面，但它不工作
我的代码如下：
AutocompliteMain.java
package com.example.autocomplite;

import android.widget.AdapterView.OnItemSelectedListener;
public class AutocompleteMain extends Activity implements OnItemClickListener,
OnItemSelectedListener {
// Initialize variables
int PICK_CONTACT = 1200;
AutoCompleteTextView textView = null;
private ArrayAdapter<String> adapter;
// Store contacts values in these arraylist
public static ArrayList<String> phoneValueArr = new ArrayList<String>();

String toNumberValue = "";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.autocomplete_main);
final Button Send = (Button) findViewById(R.id.Send);
// Initialize AutoCompleteTextView values
textView = (AutoCompleteTextView) findViewById(R.id.toNumber);
// Create adapter
adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line,
new ArrayList<String>());
textView.setThreshold(1);
// Set adapter to AutoCompleteTextView
textView.setAdapter(adapter);
textView.setOnItemClickListener(this);
// Read contact data and add data to ArrayAdapter
// ArrayAdapter used by AutoCompleteTextView
readContactData();
/********** Button Click pass textView object ***********/
Send.setOnClickListener(BtnAction(textView));
}
private OnClickListener BtnAction(final AutoCompleteTextView toNumber) {
return new OnClickListener() {
public void onClick(View v) {
String NameSel = "";
NameSel = toNumber.getText().toString();
final String ToNumber = toNumberValue;
if (ToNumber.length() == 0) {

"Please fill phone number", Toast.LENGTH_SHORT)
.show();
} else {

.getString(cur
