在java文档中预先设置好需要提示的字串,默认设置是输入两个字符的时候提醒,但是可以在java文件里面使用setThreshold() 方法实现更改提醒是输入的字符数,但是提醒的文字需要预先匹配
附上代码:
xml文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools= "http://schemas.android.com/tools"
android:layout_width= "match_parent"
android:layout_height= "match_parent"
android:orientation= "vertical"
tools:context= ".MainActivity" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="hello" />
<AutoCompleteTextView
android:id="@+id/autocomplete"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</AutoCompleteTextView >
</LinearLayout>
java文件:
package com.just;
import android.os.Bundle;
import android.app.Activity;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
public class MainActivity extends Activity {
private static final String[] autostr = new String[] { "a" , "abc" , "abcd" ,
"abcde", "abcdef" };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout. activity_main);
ArrayAdapter<?> adapter = new ArrayAdapter<Object>(this,
android.R.layout. simple_dropdown_item_1line, autostr );
AutoCompleteTextView myautoview = (AutoCompleteTextView) findViewById(R.id.autocomplete );
myautoview.setThreshold(3);
myautoview.setAdapter(adapter);
}
}
ps:在使用新窗口的同时一定要是用adapter来实现
