各种监听事件
1.按钮 Button
（1）点击监听
btn_1.setOnClickListener(new View.OnClickListener() {
（2）长按监听
btn_1.setOnLongClickListener(new View.OnLongClickListener() {
2.单选框 RadioGroup
radio_gp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
3.复选框 CheckBox（普通内部类）
cb_fuxuan1.setOnCheckedChangeListener(new checkboxcheckedlistener());
cb_fuxuan2.setOnCheckedChangeListener(new checkboxcheckedlistener());
private class checkboxcheckedlistener implements CompoundButton.OnCheckedChangeListener
{
4.上下文菜单 ContextMenu（需要长按才能触发）
changan_menu.setOnCreateContextMenuListener(this);
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
//获取值
public boolean onContextItemSelected(MenuItem item) {
item.getItemId()
5.进度条 SeekBar（可拖动）
sbr_td.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
6.开关 开关按钮：ToggleButton 推拉开关 Switch
tb.setOnCheckedChangeListener(new anniucheckedlistener());
private class anniucheckedlistener implements CompoundButton.OnCheckedChangeListener{
7.对话框 方法链构造 new AlertDialog.Builder(this)
单选对话框
final String[] yanse = {"红","黄","绿","蓝","白"};
.setSingleChoiceItems(yanse, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
多选对话框
final String[] yanse = {"红","黄","绿","蓝","白"};
final boolean[] bl = {true,true,false,false,false};
.setMultiChoiceItems(yanse, bl, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
自定义对话框 加载器 getLayoutInflater() setview
LayoutInflater layoutInflater = getLayoutInflater();
8.进度条 ProgressDialog
旋转进度条
final ProgressDialog pd = new ProgressDialog(this);
水平进度条
ProgressDialog pd = new ProgressDialog(this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
9.日期对话框
Calendar cl = Calendar.getInstance();
DatePickerDialog datePickerDialog = new DatePickerDialog(this,监听, cl.get(Calendar.YEAR),cl.get(Calendar.MONTH),cl.get(Calendar.DAY_OF_MONTH));
datePickerDialog.show();
监听 = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
}
}
10.时间对话框
//获取当前日期
//单例模式，设计模式的一种 静态方法
Calendar cl = Calendar.getInstance();
TimePickerDialog timePickerDialog = new TimePickerDialog(this,监听,cl.get(Calendar.HOUR),cl.get(Calendar.MINUTE),true);
timePickerDialog.show();
监听 = new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
}
}
11.ListView
(1)ArrayAdapter
//构造适配器
ArrayAdapter adapter = new ArrayAdapter(this,R.layout.listview_layout,list);
//设置适配器
listview_1.setAdapter(adapter);
//监听事件
listview_1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
(2)SimpleAdapter
SimpleAdapter simpleAdapter = new SimpleAdapter(this,im,R.layout.simple_layout,str,viewid);
simple_1.setAdapter(simpleAdapter);
simple_1.setOnItemClickListener();
(3)BaseAdapter
12.自动提示文本框
AutoCompleteTextView autv_1 = (AutoCompleteTextView)findViewById(R.id.atv_1);
13下拉列表
Spinner sper_1 = (Spinner)findViewById(R.id.sper_1);
sper_1.setAdapter(adapter);
sper_1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
14.消息提示
Resources res = Activitywenben.this.getResources();
//1.获取状态栏消息管理器
NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
//2.构建消息 用Builder构建 方法链调用
Notification nt = new Notification.Builder(this)
//3.交给管理器发出消息
manager.notify(0,nt);
