Create an array of String or get it from any function and create an ArrayAdapter of String then let the adapter to set the list for you .
创建一个字符串数组或从任何函数中获取它并创建一个字符串数组适配器，然后让适配器为您设置列表。
String[] array={"first","second item" ,"third item"};
AutoCompleteTextView textView;
ArrayAdapter<String> adapter;
textView = (AutoCompleteTextView) findViewById(R.id.et_search);
adapter = new ArrayAdapter<String>(PlayListActivity.this,
android.R.layout.simple_list_item_1, array);
textView.setAdapter(adapter);
