Android開發之自訂Notification（原始碼分享）

    Android的自訂notification選項我覺得限制還是挺多的，，官方API告訴我們它依然必須得設定icon,tittle,text三個選項，除此之外，還一定要設定pengdingintent，不少網友還反映 builder.setContent(remoteViews)後面一定要緊跟著builder.setContentIntent(pendingIntent)，要不然會報錯誤：android.app.RemoteServiceException: Bad notification posted from package。

   MainActivity代碼

package com.example.f04_notification;import android.os.Bundle;import android.app.Activity;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.support.v4.app.NotificationCompat;import android.view.View;import android.widget.Button;import android.widget.RemoteViews;public class MainActivity extends Activity {private NotificationManager manager;private Button button;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        button=(Button)this.findViewById(R.id.button1);        //擷取系統服務        manager=(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);        button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubNotificationCompat.Builder builder=new NotificationCompat.Builder(MainActivity.this);RemoteViews remoteViews=new RemoteViews(getPackageName(), R.layout.notifiaction);//因為android api的限制，自訂通知仍需要set small icon,setContentTittle,setContentTextbuilder.setSmallIcon(R.drawable.ic_launcher);builder.setContentText("hello world!");builder.setContentTitle("Android");//以上內容仍必須設定一遍remoteViews.setTextViewText(R.id.textView1, "通知來了");remoteViews.setImageViewResource(R.id.imageView1, R.drawable.ic_launcher);Intent intent=new Intent(MainActivity.this,MainActivity.class);//pendingintent的flag分為四個FLAG_CANCEL_CURRENT,FLAG_NO_CREATE,FLAG_ONE_SHOT,FLAG_UPDATE_CURRENTPendingIntent pendingIntent=PendingIntent.getActivity(MainActivity.this, 1, intent, PendingIntent.FLAG_ONE_SHOT);builder.setContent(remoteViews);builder.setContentIntent(pendingIntent);manager.notify((int)System.currentTimeMillis(), builder.build());}});    }    }

布局xml檔案

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <ImageView        android:id="@+id/imageView1"        android:contentDescription="@string/hello_world"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:layout_marginLeft="27dp"        android:layout_marginTop="33dp"        android:src="@drawable/ic_launcher" />    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignBottom="@+id/imageView1"        android:layout_marginLeft="76dp"        android:layout_toRightOf="@+id/imageView1"        android:text="@string/hello_world" /></RelativeLayout>
