Android——監聽事件總結

各類監聽事件

1.按鈕 Button
（1）點擊監聽
btn_1.setOnClickListener(new View.OnClickListener() {

（2）長按監聽
btn_1.setOnLongClickListener(new View.OnLongClickListener() {

2.單選框 RadioGroup
radio_gp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

3.複選框 CheckBox（普通內部類）
cb_fuxuan1.setOnCheckedChangeListener(new checkboxcheckedlistener());
cb_fuxuan2.setOnCheckedChangeListener(new checkboxcheckedlistener());

private class checkboxcheckedlistener implements CompoundButton.OnCheckedChangeListener
{

4.上下文菜單 ContextMenu（須要長按才能觸發）

changan_menu.setOnCreateContextMenuListener(this);
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
//獲取值
public boolean onContextItemSelected(MenuItem item) {
item.getItemId()

5.進度條 SeekBar（可拖動）

sbr_td.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

6.開關 開關按鈕：ToggleButton 推拉開關 Switch

tb.setOnCheckedChangeListener(new anniucheckedlistener());
private class anniucheckedlistener implements CompoundButton.OnCheckedChangeListener{

 

7.對話框 方法鏈構造 new AlertDialog.Builder(this)

 

單選對話框
final String[] yanse = {"紅","黃","綠","藍","白"};

 

.setSingleChoiceItems(yanse, 0, new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

 

多選對話框
final String[] yanse = {"紅","黃","綠","藍","白"};
final boolean[] bl = {true,true,false,false,false};

 

.setMultiChoiceItems(yanse, bl, new DialogInterface.OnMultiChoiceClickListener() {

public void onClick(DialogInterface dialog, int which, boolean isChecked) {

 

自定義對話框 加載器 getLayoutInflater() setview

 

LayoutInflater layoutInflater = getLayoutInflater();

 

8.進度條 ProgressDialog

 

旋轉進度條
final ProgressDialog pd = new ProgressDialog(this);

 

水平進度條
ProgressDialog pd = new ProgressDialog(this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

 

9.日期對話框
Calendar cl = Calendar.getInstance();

 

DatePickerDialog datePickerDialog = new DatePickerDialog(this,監聽, cl.get(Calendar.YEAR),cl.get(Calendar.MONTH),cl.get(Calendar.DAY_OF_MONTH));

 

datePickerDialog.show();

 

監聽 = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
}
}
10.時間對話框

//獲取當前日期
//單例模式，設計模式的一種 靜態方法
Calendar cl = Calendar.getInstance();

 

TimePickerDialog timePickerDialog = new TimePickerDialog(this,監聽,cl.get(Calendar.HOUR),cl.get(Calendar.MINUTE),true);

 

timePickerDialog.show();

 

監聽 = new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

 

}
}
11.ListView

 

(1)ArrayAdapter

 

//構造適配器
ArrayAdapter adapter = new ArrayAdapter(this,R.layout.listview_layout,list);

 

//設置適配器
listview_1.setAdapter(adapter);

 

//監聽事件
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.自動提示文本框
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.獲取狀態欄消息管理器
NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
//2.構建消息 用Builder構建 方法鏈調用
Notification nt = new Notification.Builder(this)
//3.交給管理器發出消息
manager.notify(0,nt);
