Android多个通知和多个意图 [英] Android Multiple Notifications and with multiple intents

问题描述

我有一个相当简单的应用程序，它接受用户的输入，然后将其设置为通知。用户可以创建他/她喜欢的任意数量的通知。我希望用户单击该通知并进入名为 ResultActivity 的新活动。 ResultActivity 依次从通知意图中读取 putExtras 并将其显示给用户。下面的代码允许我做几乎我想做的一切，除非按下通知，我收到上次创建的通知的 putExtra 。

I have a fairly simple app that takes the input from a user and then sets it as a notification. The user can create as many notifications as he/she likes. I want the user to click the notification and get taken to a new activity called ResultActivity. ResultActivity in turn reads in the putExtras from the notifications intent and shows it to the user. The code below allows me to do almost everything I wanted, except anytime a notification is pressed, I receive the putExtra of the last created notification.

Intent notificationIntent = new Intent(ctx, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx, i,notificationIntent,PendingIntent.FLAG_CANCEL_CURRENT);

NotificationManager nm = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

Resources res = ctx.getResources();
NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
builder.setContentIntent(contentIntent)
    .setSmallIcon(R.drawable.ic_launcher)
    .setLargeIcon(BitmapFactory.decodeResource(res,R.drawable.ic_launcher))
    .setTicker("Remember to " + text.getText())
    .setWhen(System.currentTimeMillis()).setAutoCancel(true)
    .setContentTitle(text.getText());

// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, ResultActivity.class);
String pass = text.getText().toString();

resultIntent.putExtra("title", pass);
resultIntent.putExtra("uid", i);

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

new Uri.Builder().scheme("data").appendQueryParameter("text", "my text").build();
builder.setContentIntent(resultPendingIntent);

Notification n = builder.build();
n.flags = Notification.FLAG_NO_CLEAR;
nm.notify(i++, n);
text.setText(null);

输入Two

现在你有两个通知。一个说一个，一个说两个。如果您单击通知两个，它会将您带到显示两个的屏幕。完美！

Now you have two notifications. One that says "One" and one that says "Two". If you click on the notification "Two" it takes you to a screen that says "Two". Perfect!

如果点击通知One，它会转到一个显示Two的屏幕。 BROKEN！

If you click on the notification "One" it takes you to a screen that says "Two". BROKEN!

public class ResultActivity extends Activity {
    String title = null;
    TextView text;

    int i=0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        text = (TextView) findViewById(R.id.textView1);



        title = getIntent().getStringExtra("title");
         i = getIntent().getIntExtra("uid", 0);


        text.setText(title);

    }

推荐答案

你创建混合的多个意图。我清理了代码（但没有测试它）

You create multiple intents that are mixed. I cleaned up the code (but did not test it)

    NotificationManager nm = (NotificationManager) ctx
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Resources res = ctx.getResources();

    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, ResultActivity.class);
    String pass = text.getText().toString();
    resultIntent.setData(new Uri.Builder().scheme("data")
            .appendQueryParameter("text", "my text").build());
    resultIntent.putExtra("title", pass);
    resultIntent.putExtra("uid", i);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(ResultActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
            PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
    builder.setSmallIcon(R.drawable.ic_launcher)
            .setLargeIcon(
                    BitmapFactory.decodeResource(res,
                            R.drawable.ic_launcher))
            .setTicker("Remember to " + text.getText())
            .setWhen(System.currentTimeMillis()).setAutoCancel(true)
            .setContentTitle(text.getText())
            .setContentIntent(resultPendingIntent);

    Notification n = builder.build();
    n.flags = Notification.FLAG_NO_CLEAR;
    nm.notify(i++, n);

    text.setText(null);
