自定义的AlterDialog

1.自定义ALterDialog需要自定义布局，并且通过getLayoutInflater找到该布局，添加一个自定义的View，然后就填写内容

 public void showDialogZidingyi() {
        mDialog = new Dialog(MainActivity.this, R.style.NoTitleNobackground);
        LayoutInflater inflater = getLayoutInflater();
        View dialogView = inflater.inflate(R.layout.dialog_zidingyi, null);
        TextView textViewTitle = (TextView) dialogView.findViewById(R.id.textview_title);
        textViewTitle.setText("这是新的标题");
        TextView textViewMessage = (TextView) dialogView.findViewById(R.id.textview_message);
        textViewMessage.setText("这是新的内容");
        Button buttonCancle = (Button) dialogView.findViewById(R.id.button_cancle);
        buttonCancle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mDialog.dismiss();
            }
        });
        Button buttonOK = (Button) dialogView.findViewById(R.id.button_ok);
        buttonOK.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "点击确定", Toast.LENGTH_SHORT).show();
                mDialog.dismiss();
            }
        });
//                mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        mDialog.setContentView(dialogView);
        mDialog.show();
    }
<?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_background">
    <TextView
        android:id="@+id/textview_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="DialogTitle"
        style="@style/MyTextView"
        />
    <TextView
        android:id="@+id/textview_message"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:text="Message"
        android:gravity="center"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <Button
            android:id="@+id/button_cancle"
            android:layout_width="0dip"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="Cancle"
            android:background="@drawable/btn_left_background"/>
        <Button
            android:id="@+id/button_ok"
            android:layout_width="0dip"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="OK"
            android:background="@drawable/btn_right_background"/>
    </LinearLayout>
</LinearLayout>

DatePickerDialog比较简单代码如下：

public void showDatePickerDialog() {
        mCalendar= Calendar.getInstance();
        DatePickerDialog dialog=new DatePickerDialog(MainActivity.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(), "造型成了" + format.format(mCalendar.getTime()), Toast.LENGTH_SHORT).show();
            }
        },mCalendar.get(Calendar.YEAR),mCalendar.get(Calendar.MONTH),mCalendar.get(Calendar.DAY_OF_MONTH));
        dialog.show();
    }

TimePickerDialog也比较简单代码如下：

public void showTimePickerDialog() {
        mCalendar= Calendar.getInstance();
        TimePickerDialog dialog=new TimePickerDialog(MainActivity.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(), "选择的时间是" + format.format(mCalendar.getTime()), Toast.LENGTH_SHORT).show();
            }
        },mCalendar.get(Calendar.HOUR),mCalendar.get(Calendar.MINUTE),true);
        dialog.show();
    }

PopupWindows需要自定义一个Layout其代码如下：

mPopupWindow=new PopupWindow(MainActivity.this);
                View popView=getLayoutInflater().inflate(R.layout.popupwindow_layout,null);
                mPopupWindow.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
                mPopupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
                mPopupWindow.setContentView(popView);
                mPopupWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.dialog_background));
                mPopupWindow.setFocusable(false);
                mPopupWindow.setOutsideTouchable(true);
                mPopupWindow.showAsDropDown(mButton8);
<?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">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:gravity="center"
        android:text="ONE"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:gravity="center"
        android:text="TWO"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:gravity="center"
        android:text="THREE"/>

</LinearLayout>

Notification就是手机上的通知

1.一种比较简单的通知：其代码如下：

 public void notification1() {
        Notification notification=new Notification();
        notification.icon= R.mipmap.ic_launcher;//设置图标
        notification.tickerText="有一条消息";//设置状态栏文本
        notification.flags=Notification.FLAG_AUTO_CANCEL;//设置为可以取消
        Intent intent=new Intent(getApplicationContext(),MainActivityNotification.class);//设置PendingIntent事件
        PendingIntent pend=PendingIntent.getActivity(getApplicationContext(),1,intent,PendingIntent.FLAG_ONE_SHOT);//设置PendingIntent使用方式
        notification.setLatestEventInfo(getApplicationContext(),"标题","内容",pend);//设置PendingIntent的显示内容
        notification.when=System.currentTimeMillis();//设置触发时间
        mNotificationManager.notify(1,notification);//通知管理器将通知添加
    }

2.另一种通知的写法：

 Intent intent=new Intent(getApplicationContext(),MainActivityNotification.class);//设置PendingIntent事件
                PendingIntent pend=PendingIntent.getActivity(getApplicationContext(),1,intent,PendingIntent.FLAG_ONE_SHOT);//设置PendingIntent使用方式
                Notification notification=new Notification.Builder(MainActivityNotification.this).setSmallIcon(R.mipmap.ic_launcher).setTicker("有一条消息").
                        setContentTitle("标题").setContentText("文本").setContentInfo("内容").setContentIntent(pend).setWhen(System.currentTimeMillis()).
                        setAutoCancel(true).build();
                mNotificationManager.notify(2,notification);
