Android27_AutoCompleteTextView

 

一、创建AutoCompleteTextView

       1.在布局文件中声明一个AutoCompleteTextView

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="text" />
<AutoCompleteTextView android:id="@+id/actv"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"/> 

       2.定义提示条目的样式,创建布局文件:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:textSize="16sp"
    android:textColor="#000">
</TextView>

         3.创建一个ArrayAdapter,用来提供数据:

autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.actv);
List<String> list = new ArrayList<String>();
list.add("allotory");
list.add("bauble");
list.add("baobo");
list.add("album");
list.add("alow");
list.add("array");

        4.AutoCompleteTextView设置数据

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,R.layout.item ,list);
        autoCompleteTextView.setAdapter(arrayAdapter);

 完整代码:

Main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="5dp">
<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="text" />
<AutoCompleteTextView android:id="@+id/actv"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"/>
</LinearLayout>

 Item.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:textSize="16sp"
    android:textColor="#000">
</TextView>

 AutoCompleteTextViewActivity.java

package com.android.activity;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
public class AutoCompleteTextViewActivity extends Activity {
	private AutoCompleteTextView autoCompleteTextView = null;
	@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        autoCompleteTextView = 
			(AutoCompleteTextView)findViewById(R.id.actv);
        List<String> list = new ArrayList<String>();
        list.add("allotory");
        list.add("bauble");
        list.add("baobo");
        list.add("album");
        list.add("alow");
        list.add("array");
        ArrayAdapter<String> arrayAdapter = 
			new ArrayAdapter<String>(this,R.layout.item ,list);
        autoCompleteTextView.setAdapter(arrayAdapter);
    }
}
