Question

我正在尝试在我的应用中实施Android直接回复通知。 我已成功在Android N模拟器中成功实施。但它不适用于Marshmallow设备。当我点击通知中的操作按钮时，回复edittext没有显示在Android N以下的设备中。我知道这个功能可以在Android N之前的设备中使用，因为它可以在WhatsApp中使用。

我的问题是如何让它在Android N之前的设备中运行？我在这里分享我的代码。任何帮助都会很棒。感谢。

MainActivity

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.RemoteInput;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends AppCompatActivity {

// Key for the string that's delivered in the action's intent.
public static final String KEY_TEXT_REPLY = "key_text_reply";
private static final int notificationID = 1234;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);




    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

        startNotif();
        }
    });
}

private void startNotif() {

    Intent intent = new Intent(this, NotificationReciever.class);
// use System.currentTimeMillis() to have a unique ID for the pending intent
    final PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

    String replyLabel = "Reply";
    RemoteInput remoteInput = new RemoteInput.Builder(KEY_TEXT_REPLY)
            .setLabel(replyLabel)
            .build();

    // Create the reply action and add the remote input.
    Notification.Action action =
            new Notification.Action.Builder(R.drawable.ic_send,
                    "Action", pIntent)
                    .addRemoteInput(remoteInput)
                    .build();

    // Build the notification and add the action.
    Notification newMessageNotification =
            new Notification.Builder(MainActivity.this)
                    .setSmallIcon(R.drawable.ic_remove_circle_black_48dp)
                    .setContentTitle("Title")
                    .setContentText("Content")
                    .addAction(action).build();

// Issue the notification.
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(notificationID, newMessageNotification);
    }
}

NotificationReciever

import android.app.Activity;
import android.app.RemoteInput;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

/**

 */
public class NotificationReciever extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Toast.makeText(this,getMessageText(getIntent()),Toast.LENGTH_SHORT).show();
    }

    private CharSequence getMessageText(Intent intent) {
        Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);
        if (remoteInput != null) {
            return remoteInput.getCharSequence(MainActivity.KEY_TEXT_REPLY);
        }
        Toast.makeText(this,"Remoteinput is null",Toast.LENGTH_SHORT).show();

        return null;
    }
}

Answer 1

在文档中，它告诉您不要使用广播接收器或服务用于低于N的api。因此，您必须启动一个符合您想要的活动并将其包装在待处理的意图中。

if (isDirectReplySupported) {
  return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);
}
return PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

Answer 2

实现此功能非常简单，首先制作一个广播接收器，像往常一样创建一个动作按钮＆amp;与pendingintent联系。

然后将该意图连接到推送通知对象＆amp;通知。

在broadcastreceiver处理阅读文本部分＆amp;更新为通知。
