本文实例讲述了Android实现为Notification加上一个进度条的方法。分享给大家供大家参考，具体如下：

package com.notification; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Intent; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.RemoteViews; import android.widget.Toast; public class nofificationActivity extends Activity implements OnClickListener { private static final int NOTIFICATION_ID = 0x12; private Notification notification = null; private NotificationManager manager = null; public Handler handler; private int _progress = 0; private Thread thread = null; private boolean isStop = false; // 当界面处理停止的状态 时，设置让进度条取消 @Override protected void onPause() { // TODO Auto-generated method stub isStop = false; manager.cancel(NOTIFICATION_ID); super.onPause(); } /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btn = (Button) findViewById(R.id.Button01); btn.setOnClickListener(this); notification = new Notification(R.drawable.icon, "带进条的提醒", System .currentTimeMillis()); notification.icon = R.drawable.icon; // 通过RemoteViews 设置notification中View 的属性 notification.contentView = new RemoteViews(getApplication() .getPackageName(), R.layout.custom_dialog); notification.contentView.setProgressBar(R.id.pb, 100, 0, false); notification.contentView.setTextViewText(R.id.tv, "进度" + _progress + "%"); // 通过PendingIntetn // 设置要跳往的Activity，这里也可以设置发送一个服务或者广播， // 不过在这里的操作都必须是用户点击notification之后才触发的 notification.contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, remoteView.class), 0); // 获得一个NotificationManger 对象，此对象可以对notification做统一管理，只需要知道ID manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); } @Override public void onClick(View v) { // TODO Auto-generated method stub isStop = true; manager.notify(NOTIFICATION_ID, notification); thread = new Thread(new Runnable() { @Override public void run() { Thread.currentThread(); // TODO Auto-generated method stub while (isStop) { _progress += 10; Message msg = handler.obtainMessage(); msg.arg1 = _progress; msg.sendToTarget(); try { Thread.sleep(500); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); thread.start(); handler = new Handler() { @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub notification.contentView.setProgressBar(R.id.pb, 100, msg.arg1, false); notification.contentView.setTextViewText(R.id.tv, "进度" + msg.arg1 + "%"); manager.notify(NOTIFICATION_ID, notification); if (msg.arg1 == 100) { _progress = 0; manager.cancel(NOTIFICATION_ID); isStop = false; Toast.makeText(nofificationActivity.this, "下载完毕", 1000) .show(); } super.handleMessage(msg); } }; } }

希望本文所述对大家Android程序设计有所帮助。
