创建一个 String 数组或从任何函数获取它并创建一个 String ArrayAdapter 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);

创建一个项目AutoCompleteTextView
并将代码粘贴到所需位置 -
主要的.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<AutoCompleteTextView android:id="@+id/myautocomplete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:completionThreshold="1"
/>
</LinearLayout>
AutoCompleteTextview.java
public class AndroidAutoCompleteTextView extends Activity implements TextWatcher{
AutoCompleteTextView myAutoComplete;
String item[]={
"January", "February", "March", "April",
"May", "June", "July", "August",
"September", "October", "November", "December"
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myAutoComplete = (AutoCompleteTextView)findViewById(R.id.myautocomplete);
myAutoComplete.addTextChangedListener(this);
myAutoComplete.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, item));
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
}
只需使用此示例。并且,弄清楚他们如何将适配器设置为AutoComplete TextView
希望这对您有所帮助。
