本文介绍了一个简单的Android应用示例，展示了如何通过按钮触发通知，并实现通知点击后的页面跳转功能。应用中包含了通知的创建、显示及取消操作，并通过PendingIntent实现了通知点击后的新Activity启动。

先是布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="us.mifeng.xiaoxituisong.MainActivity" >

    <Button 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="出来"
        android:id="@+id/queren"
        />
	<Button 
	    android:layout_width="match_parent"
	    android:layout_height="wrap_content"
	    android:id="@+id/quxiao"
	    android:text="取消"
	    
	    
	    />
</LinearLayout>

然后是mainacitvity

package us.mifeng.xiaoxituisong;

import android.annotation.SuppressLint;
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.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {
	private int i = 0;
	private Button queren,quxiao;
	private NotificationManager manager;
	private Notification nf = null;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		queren = (Button) findViewById(R.id.queren);
		quxiao = (Button) findViewById(R.id.quxiao);
	
		queren.setOnClickListener(this);
		quxiao.setOnClickListener(this);
		manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		int in = v.getId();
		switch (v.getId()) {
		case R.id.queren:
			i++;
			initView();
			manager.notify(i,nf);
			break;

		default:
			manager.cancel(i);//点击取消消息
			break;
		}
	}

	@SuppressLint("NewApi")
	private void initView() {
		Notification.Builder builder = new Notification.Builder(this);
		builder.setSmallIcon(R.drawable.ic_launcher);
		builder.setTicker("外报,外报 ,外报");//设置通知大图标
		builder.setContentText("xxx嫖娼被捕,xxx嫖娼被捕,xxx嫖娼被捕");//设置内容
		builder.setContentTitle("人名日报");//设置标题
		builder.setAutoCancel(true);
		Intent intent = new Intent(this,NewActivity.class);
		intent.putExtra("i","xxx嫖娼被捕,xxx嫖娼被捕,xxx嫖娼被捕"+i);
		//创建一个
		PendingIntent pend = PendingIntent.getActivity(this, 1, intent,PendingIntent.FLAG_CANCEL_CURRENT);
		builder.setContentIntent(pend);
		nf = builder.build();
	}
}

然后就是要跳转页面的内容

package us.mifeng.xiaoxituisong;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.widget.TextView;

public class NewActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		TextView tv = new TextView(this);
		Intent intent = this.getIntent();
		String string = intent.getStringExtra("i");
		tv.setText(string);
		tv.setTextSize(30);
		tv.setTextColor(Color.parseColor("#FF6600"));
		setContentView(tv);
	}
}
