Java 当我点击推送通知时，特定活动不会'；t打开（需要真正的帮助）

通知时未打开特定活动当应用程序处于后台/未运行时单击

只有在打开应用程序并执行通知单击时，通知单击才会启动指定的活动。如果应用程序处于后台/未运行且执行了通知单击，则应用程序的MainActivity将打开。简言之，这就像应用程序在活动堆栈之后正常打开，而不是在PendingEvent中打开指定的活动

不幸的是，我在这个论坛上看到了类似于这个问题的解决方案

MyApplication

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        OneSignal.startInit(this).setNotificationOpenedHandler(new ExampleOpenHandler())
                .autoPromptLocation(true).init();

    }

    private class ExampleOpenHandler implements OneSignal.NotificationOpenedHandler {

        @Override
        public void notificationOpened(OSNotificationOpenResult result) {

            JSONObject data=result.notification.payload.additionalData;

            Intent intent = new Intent(getApplicationContext(),SecondActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);

            try{

                intent.putExtra("datam",data.getString("1"));
            }catch (JSONException e) {
                e.printStackTrace();

            }
            startActivity(intent);
        }
    }
}

第二活动

public class SecondActivity extends AppCompatActivity {

    TextView dataview;
    String getdata;

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

        getdata = getIntent().getExtras().getString("datam");

        dataview = (TextView) findViewById(R.id.dataview);
        dataview.setText(getdata);
    }
}

要启动包含活动后堆栈的活动，需要创建TaskStackBuilder实例并调用addNextEntWithParentStack（），将要启动的活动的意图传递给它
