Android 控件：AutoCompleteTextView，MultiAutoCompleteTextView ，TimePicker ，DatePicker，Spinner 的简单使用

* 代码太easy了，就不说废话了，直接一个xml，一个Activity完事。

* AutoCompleteTextView：自动匹配的编辑框；

* MultiAutoCompleteTextView 自动匹配的编辑框，可匹配多个；

* TimePicker 时间选择器;

* DatePicker 日期选择器；

* Spinner 下拉框；

xml如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <AutoCompleteTextView
        android:id="@+id/atv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:completionThreshold="2"
        android:hint="haha" />

    <MultiAutoCompleteTextView
        android:id="@+id/matv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:completionThreshold="3"
        android:hint="duck" />

    <TimePicker
        android:id="@+id/timePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <DatePicker
        android:id="@+id/datePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

Activity如下：

package com.example.duckeatcake;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.DatePickerDialog.OnDateSetListener;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.MultiAutoCompleteTextView;
import android.widget.MultiAutoCompleteTextView.CommaTokenizer;
import android.widget.Spinner;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;
import android.widget.Toast;

public class CatActivity extends Activity {

	private AutoCompleteTextView atv;
	private MultiAutoCompleteTextView matv;
	private TimePicker timePicker;
        private DatePicker datePicker;
        private Spinner spinner;
        private int year;
	private int month;
	private int day;
	private int hour;
	private int minute;
	private int second;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.cat);
		atv = (AutoCompleteTextView) findViewById(R.id.atv);

		String[] objects = new String[] { "be fucked by cat", "cat fuck me",
				"duct", "duck", "duck fuck you", "duck fuck me",
				"be fucked by duck", "be fuck" };
		ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_1, objects);
		atv.setAdapter(adapter);

		matv = (MultiAutoCompleteTextView) findViewById(R.id.matv);
		matv.setAdapter(adapter);
		matv.setTokenizer(new CommaTokenizer());

		Calendar calendar = Calendar.getInstance();
		year = calendar.get(Calendar.YEAR);
		month = calendar.get(Calendar.MONTH) + 1;
		day = calendar.get(Calendar.DAY_OF_MONTH);
		hour = calendar.get(Calendar.HOUR_OF_DAY);
		minute = calendar.get(Calendar.MINUTE);
		second = calendar.get(Calendar.SECOND);

		setTitle("Date: " + year + "-" + month + "-" + day + " " + hour + ":"
				+ minute + ":" + second);
		// 时间选择器
		timePicker = (TimePicker) findViewById(R.id.timePicker);
		timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {

			@Override
			public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
				setTitle("Date: " + year + "-" + month + "-" + day + " "
						+ hourOfDay + ":" + minute);

			}
		});
		datePicker = (DatePicker) findViewById(R.id.datePicker);
		datePicker.init(year, calendar.get(Calendar.MONTH), day,
				new OnDateChangedListener() {

					@Override
					public void onDateChanged(DatePicker view, int year,
							int monthOfYear, int dayOfMonth) {
						setTitle("Date: " + year + "-" + (monthOfYear + 1)
								+ "-" + dayOfMonth + " ");

					}
				});
		datePicker.setVisibility(View.GONE);//
		// 日期选择器对话框
		new DatePickerDialog(this, new OnDateSetListener() {

			@Override
			public void onDateSet(DatePicker view, int year, int monthOfYear,
					int dayOfMonth) {
				setTitle("####Date: " + year + "-" + monthOfYear + "-"
						+ dayOfMonth);
			}
		}, year, month, day).show();

		spinner = (Spinner) findViewById(R.id.spinner);

		final String[] datas = new String[] { "北京", "上海", "广州", "深圳" };
		final ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,
				android.R.layout.simple_list_item_1, datas);
		spinner.setAdapter(adapter2);
		spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
			@Override
			public void onItemSelected(AdapterView<?> parent, View view,
					int position, long id) {
				String text = "我在" + adapter2.getItem(position) + "卖淫";
				Toast.makeText(getApplicationContext(), text,
						Toast.LENGTH_SHORT).show();
				atv.setText(text);
			}
			@Override
			public void onNothingSelected(AdapterView<?> parent) {
			}
		});
	}
}

运行效果ok.
