概述
TimePickerDialog与DatePickerDialog： 用于调整时间的控件。自定义dialog： 可以自定义显示的界面布局和内容。
PopupWindow的常用方法有：
setWidth()、setHight()、setFocusable()、setContentView()、showAsDropDown()、setBackgroundDrawable()。
Notification:
有新、老两种方法。NotificationManager用于管理Notification。
老方法：
Notification.XXX：常用属性有：icon用于设置图片，tickerText用于设置提示内容，flags用于设置标志。
新方法jdk1.6后
Buider(活动名，this)；
setTicker()：设置提示标题，setContentView()：设置自定义界面，setAutoCancel()：是否能通过点击外部取消界面，setShowWhen()：设置显示时间。
内容
DatePickerDialog与TimePickerDialog
private Calendar mCalendar;//全局变量
private void datePickerDialog() {
mCalendar = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(DialogActivity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
mCalendar.set(year,monthOfYear,dayOfMonth);
SimpleDateFormat format = new SimpleDateFormat("yyyy年MM月dd日");
Toast.makeText(getApplicationContext(),format.format(mCalendar.getTime()),Toast.LENGTH_SHORT).show();
}
},mCalendar.get(Calendar.YEAR),mCalendar.get(Calendar.MONTH),mCalendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}private void timePickerDialog() {
mCalendar = Calendar.getInstance();
TimePickerDialog dialog = new TimePickerDialog(DialogActivity.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mCalendar.set(Calendar.HOUR,hourOfDay);
mCalendar.set(Calendar.MINUTE,minute);
SimpleDateFormat format = new SimpleDateFormat("yyyy年MM月dd日HH：mm");
Toast.makeText(getApplicationContext(),format.format(mCalendar.getTime()),Toast.LENGTH_SHORT).show();
}
},mCalendar.get(Calendar.HOUR),mCalendar.get(Calendar.MINUTE),true);
dialog.show();
}结果演示：
自定义Dialog
public void customDialog(){
mDialog = new Dialog(DialogActivity.this,R.style.DialogNoTitle);
LayoutInflater inflater = getLayoutInflater();
final View dialogView = inflater.inflate(R.layout.layout_custom_dialog, null);
TextView textViewContent = (TextView)dialogView.findViewById(R.id.text_dialog_content);
Button button_cancel = (Button)dialogView.findViewById(R.id.button_cancle);
Button button_ok = (Button)dialogView.findViewById(R.id.button_ok);
textViewContent.setText("重新设定的内容");
button_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mDialog.dismiss();
}
});
button_ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "您选择了ok", Toast.LENGTH_SHORT).show();
mDialog.dismiss();
}
});
//mDialog.setTitle("我是标题");
// mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.setContentView(dialogView);
mDialog.show();
}Dialog的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"

PopupWindow
private PopupWindow mPopupWindow;//设定为全局变量
private void showPopupWindow(){
mPopupWindow = new PopupWindow(DialogActivity.this);
View popView = getLayoutInflater().inflate(R.layout.layout_popup_window,null);
mPopupWindow.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
mPopupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
mPopupWindow.setContentView(popView);
mPopupWindow.setOutsideTouchable(true);
mPopupWindow.setFocusable(false);
mPopupWindow.showAsDropDown(dialogButton2);
}popupWindow的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/dialog_bg">
<TextView
android:id="@+id/text1_popup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:text="文本1"/>
<TextView
android:id="@+id/text2_popup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="文本2"
android:layout_margin="20dp"/>
<TextView
android:id="@+id/text3_popup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:text="文本3"/>
</LinearLayout>点击后退便能推迟PopupWindow，需要加一段代码
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(keyCode==KeyEvent.KEYCODE_BACK) {
if(mPopupWindow!=null&&mPopupWindow.isShowing()){
mPopupWindow.dismiss();
return true;
}
}
return super.onKeyDown(keyCode, event);
}结果演示：
