问题描述
当尝试单击FCM生成的通知时，我试图从启动器活动中打开一个活动.即使执行了上面编写的log语句，startActivity函数也不执行任何操作.以下是一些相关的文件/功能，请说明为什么ConversationDetailActivity无法启动:
I am trying to open an activity from the launcher activity when an FCM-generated notification gets clicked. The startActivity function does nothing even when the log statement written above gets executed. Following are some relevant files/functions, please tell why is the ConversationDetailActivity not starting:
从LoginActivity启动另一个活动的功能
void handleNotificationClick()
{
if (getIntent().getExtras() != null)
{
for (String key : getIntent().getExtras().keySet())
{
Object value = getIntent().getExtras().get(key);
System.out.println("----- pushNotif Key: " + key + " Value: " + value);
}
Intent intent;
if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_CATEGORY).equals(Master.KEY_PUSH_NOTIFICATION_CONVERSATION))
{
intent = new Intent(LoginActivity.this, ConversationDetailActivity.class);
}
else
{
intent = new Intent(LoginActivity.this, ApprovalDetailActivity.class);
if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_APPROVAL_TYPE).equals("I"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS);
else if(getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_APPROVAL_TYPE).equals("A"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS);
else
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED);
intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false);
}
intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , getIntent().getStringExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID));
intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true);
intent.putExtra(Master.KEY_POSITION, 0);
System.out.println("----- starting new activity from handleNotificationClick");
LoginActivity.this.startActivity(intent);
LoginActivity.this.finish();
}
}
从中生成通知的sendNotification函数
private void sendNotification(String messageBody)
{
Intent intent;
System.out.println("----message body: " + messageBody);
if(notificationBundle.getCategory().equalsIgnoreCase(Master.KEY_PUSH_NOTIFICATION_CONVERSATION))
{
intent = new Intent(this, ConversationDetailActivity.class);
}
else
{
intent = new Intent(this, ApprovalDetailActivity.class);
if(notificationBundle.getApprovalType().equals("I"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_VERIFICATIONS);
else if(notificationBundle.getApprovalType().equals("A"))
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_APPROVALS);
else
intent.putExtra(Master.KEY_WHICH_APPROVAL, Master.KEY_COMPLETED);
intent.putExtra(Master.KEY_IS_FROM_CONVERSATION, false);
}
intent.putExtra(Master.KEY_PUSH_NOTIFICATION_POST_ID , notificationBundle.getPostID());
intent.putExtra(Master.KEY_IS_FROM_PUSH_NOTIFICATION, true);
intent.putExtra(Master.KEY_POSITION, 0);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.mnet_icon)
.setContentTitle(getString(R.string.app_name))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
int random = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
notificationManager.notify(random, notificationBuilder.build());
}

推荐答案
在清单中，定义要打开的类，像这样
In your manifest, define your class which you want to open like this
<activity
android:name=".activities.ApprovalDetailActivity"
android:exported="true"
android:screenOrientation="portrait"
android:theme="@style/MyMaterialTheme"
android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
