编码实现软件通知

构建新的xml

package cn.itcast.codeui;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.LinearLayout;import android.widget.TextView;public class MainActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        LinearLayout linearLayout = new LinearLayout(this);        linearLayout.setOrientation(LinearLayout.VERTICAL);                TextView textView = new TextView(this);        textView.setText(R.string.hello);        ViewGroup.LayoutParams textViewParams = new ViewGroup.LayoutParams(        ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);        linearLayout.addView(textView, textViewParams);        View partView = getPartUI();  //该部分是固定的 上面是动态的        linearLayout.addView(partView);                ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(        ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);        setContentView(linearLayout, layoutParams);    }        private View getPartUI(){    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);    return inflater.inflate(R.layout.part, null); //由界面文件生成一个view对象，要不要挂一个父类元素    }}

part.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="vertical" >    <EditText        android:layout_width="fill_parent"        android:layout_height="wrap_content"       />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"           android:text="添加"             /></LinearLayout>

通知

string.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="hello">Hello World, MainActivity!</string>    <string name="app_name">发送通知</string>    <string name="shorttitle">概要</string>    <string name="title">标题</string>    <string name="content">内容</string>    <string name="button">发送</string></resources>

layout.xml

MainActivity.java

package cn.itcast.notification;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.widget.EditText;public class MainActivity extends Activity {    private EditText shorttitleText;    private EditText titleText;    private EditText contentText;        @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                shorttitleText = (EditText) this.findViewById(R.id.shorttitle);        titleText = (EditText) this.findViewById(R.id.title);        contentText = (EditText) this.findViewById(R.id.content);    }        public void send(View v){    String tickerText = shorttitleText.getText().toString();    String title = titleText.getText().toString();    String content = contentText.getText().toString();    int icon = android.R.drawable.stat_notify_chat;    Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());    Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:194949494"));    PendingIntent pendingIntent = PendingIntent.getActivity(this, 10, intent, 0);    notification.setLatestEventInfo(this, title, content, pendingIntent); // pengingIntent 指点击通知时候打开那个应用    notification.defaults = Notification.DEFAULT_SOUND;//声音    notification.flags = Notification.FLAG_AUTO_CANCEL; //通知被点击则取消显示        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);    manager.notify(100, notification);//100是id 自定义唯一    }}
