Android 带过滤的自动完成文本视图

我正在开发一个应用程序，当我在

TextField

中输入文本时，它会给出保存在联系人列表中的匹配结果。但是，当我在

文本字段中输入任何内容时，它会给出电话簿中保存的所有号码，而且当我单击搜索号码时，它不会在
文本字段中输入

我的java代码

  LocalAdapter adapter = new LocalAdapter(this, MyActivity.phoneBook);
  AutoCompleteTextView textView = (AutoCompleteTextView) myView.findViewById(R.id.editText);
  textView.setAdapter(adapter);
  return myView;}

您的onclick侦听器似乎不工作，请检查此PassableOnClick侦听器。在这一行中，myRow.setOnClickListener（新的PassableOnClickListener（myfrag，position））；这是“联系人”选项卡，工作正常。您的onclick侦听器似乎不工作。请检查此PassableOnClick侦听器。在这一行中，myRow.setOnClickListener（新的PassableOnClickListener（myfrag，position））；这是“联系人”选项卡，工作正常
