android学习笔记五——AutoCompleteTextView

AutocompleteTextview

==>

使用比较容易，只需要为其设置一个Adapter，该Adapter封装其需要预设的文本内容。

如下所示实例：

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".IndexActivity" >

    <AutoCompleteTextView
        android:id="@+id/autoText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:completionHint="请选择你喜欢的书籍"
        android:dropDownHorizontalOffset="20dp"
        android:completionThreshold="1"
        />

</RelativeLayout>

　　

package com.example.myautocompletetextview;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class IndexActivity extends Activity
{
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.index);

		Log.i("swg", "autocompletetextview");

		String[] books =
		{ "孙悟空大战红孩儿", "小兵张嘎", "三毛流浪记", "鲁宾逊漂流记", "android高级编辑" };

		ArrayAdapter<String> temp = new ArrayAdapter<String>(this,
				android.R.layout.simple_dropdown_item_1line, books);

		AutoCompleteTextView txtView = (AutoCompleteTextView) this
				.findViewById(R.id.autoText);
		// 设置Adapter
		txtView.setAdapter(temp);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu)
	{
		getMenuInflater().inflate(R.menu.index, menu);
		return true;
	}

}
