Launch Activity

Let’s start this activity by creating a notification with reply option.

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.RemoteInput;
import android.support.v4.app.TaskStackBuilder;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class LaunchActivity extends AppCompatActivity {
    // Key for the string that's delivered in the action's intent.
    private static final String KEY_TEXT_REPLY = "key_text_reply";

    // mRequestCode allows you to update the notification later on.
    int mRequestCode = 1000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_launch);

        // Create the RemoteInput specifying this key
        String replyLabel = getString(R.string.reply_label);
        RemoteInput remoteInput = new RemoteInput.Builder(KEY_TEXT_REPLY)
                .setLabel(replyLabel)
                .build();

        Intent resultIntent = new Intent(this, NotificationActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(NotificationActivity.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
                );

        // Add to your action, enabling Direct Reply for it
        NotificationCompat.Action action =
                new NotificationCompat.Action.Builder(R.drawable.ic_stat_social_notifications_on, replyLabel, resultPendingIntent)
                        .addRemoteInput(remoteInput)
                        .setAllowGeneratedReplies(true)
                        .build();

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .addAction(action)
                        .setAutoCancel(true)
                        .setSmallIcon(R.drawable.ic_stat_social_notifications_on)
                        .setContentTitle("DevDeeds Says")
                        .setContentText("Do you like my tutorials ?");

        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        //Show it
        mNotificationManager.notify(mRequestCode, mBuilder.build());
    }
}

Notification Activity

This is the opening/resulting activity when you give reply to the notification. Here we update the created notification with “Thank you” message. Updation is performed based on the request code, which is 1000.

From Intent we will get entered message by key key_text_reply

import android.app.NotificationManager;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.RemoteInput;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

public class NotificationActivity extends AppCompatActivity {

    // Key for the string that's delivered in the action's intent.
    private static final String KEY_TEXT_REPLY = "key_text_reply";

    // mRequestCode allows you to update the notification.
    int mRequestCode = 1000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notification);

        TextView textView = (TextView) findViewById(R.id.replyMessage);
        textView.setText(getMessageText(getIntent()));

        String returnMessage = "Thank you";

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_stat_toggle_check_box)
                        .setContentText(returnMessage);

        NotificationManager mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        //update notification
        mNotificationManager.notify(mRequestCode, mBuilder.build());
    }

    private CharSequence getMessageText(Intent intent) {
        Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);
        if (remoteInput != null) {
            return remoteInput.getCharSequence(KEY_TEXT_REPLY);
        }
        return null;
    }
}


Result

devdeeds_notification_reply_in_action
