Question

我正在尝试将此代码

import android.app.Dialog;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.Uri;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

/**
 * AppRater is a simple helper for Android developers, which helps getting
 * engaged users to vote the app. It requires a certain number of launches
 * and days installed before the rating dialog appears.
 * 
 * Adjust APP_TITLE and APP_PNAME to your needs. You should also tweak
 * DAYS_UNTIL_PROMPT and LAUNCHES_UNTIL_PROMPT.
 * 
 * To test it and to tweak the dialog appearence, you can call
 * `AppRater.showRateDialog(this, null)` from your Activity.
 * 
 * Normal use is to invoke `AppRater.app_launched(this)` each time your 
 * activity is invoked (eg. from within the onCreate method).

我在这里找到了

https://github.com/metachris/android-apprater/blob/master/AppRater.java

根据指南

在这里找到 https://github.com/metachris/android-apprater/blob/master/README.md

我尝试使用

AppRater.showRateDialog(this, null)

在我的应用程序的主要活动中，将显示评级我的应用程序的警告对话框

然而，如果我试过

AppRater.app_launched(this)

即使我已经改变了

，也没有任何反应

private final static int DAYS_UNTIL_PROMPT = 1; private final static int LAUNCHES_UNTIL_PROMPT = 3;

我尝试启动应用程序三次，甚至等待一天仍然没有警报，我应该做什么，以便在启动3次应用程序启动后或一天后显示警报< / p>

给我评价，提示用户，android警报不显示
