Question

我不知道这个问题是否被提出，但我找不到。我希望警报对话框显示每10次或更多次启动应用程序。

 AlertDialog.Builder a_builder = new AlertDialog.Builder(MainActivity.this);
 a_builder.setMessage("Please take time and rate our application")
 .setCancelable(false)
 .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
                    Uri uri = Uri.parse("market://details?id=" + getApplicationContext().getPackageName());
                    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);

                    goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY |
                            Intent.FLAG_ACTIVITY_NEW_DOCUMENT |
                            Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
                    try {
                        startActivity(goToMarket);
                    } catch (ActivityNotFoundException e) {
                        startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse("http://play.google.com/store/apps/details?id=" + getApplicationContext().getPackageName())));
                    }

                }
            }).setNegativeButton("Not Now",new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            }) ;
    AlertDialog alert = a_builder.create();
    alert.setTitle("Rate Us !");
    alert.show();

Answer 1

设置sharedPreferences并每次按存储在其中的值递增计数。当值达到计数时，只需显示警报并重置共享偏好。

      int count=0;
int prefcount;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            count++;
            SharedPreferences pref= PreferenceManager.getDefaultSharedPreferences(this);
            SharedPreferences.Editor edit=pref.edit();
            edit.putInt("Count",count);
            edit.commit();
            prefcount=pref.getInt("Count",-1);
            if(prefcount>10){
                //show dialog
            }


        }
}
Hope this will help you.

您可以在共享首选项中存储一个整数值，以计算您的应用启动次数您可以在启动活动的OnCreate（）方法或作为应用程序入口点的任何其他活动中增加值（例如来自通知）。
您应该在每次显示对话框后重置该值这是一小段代码 -

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0);
int appLaunchCount = pref.getInt("appLaunchCount",-1);
    if(appLaunchCount==10){
        // code to show dialog
        // reset
        appLaunchCount=0;
    } else {
        // increment count
        appLaunchCount = appLaunchCount+1;
    }
    SharedPreferences.Editor editor = pref.edit();
    editor.putInt("appLaunchCount", appLaunchCount);
    editor.apply();

您可以在SharedPreferences中存储开放计数

在oncreate活动上添加计数器。

SharedPreferences prefs = getSharedPreferences("user_count", MODE_PRIVATE);
SharedPreferences.Editor editor1 = getSharedPreferences("user_count", MODE_PRIVATE).edit();
int restoredCount = prefs.getInt("name", 0);



 if (restoredCount == 10) {
            editor1.putInt("name", 0);
            editor1.commit();

           // Here Show Alert Dialog.  

        }

//获取计数器值

UPDATE `wp_buddypress_dev`.`wp_usermeta` 
SET `meta_value` = REPLACE(`meta_value`, 'a:1:{s:10:"subscriber";b:1;}') 
WHERE `meta_value` = 'a:1:{s:10:"a:1:{s:10:"subscriber";b:1;}";';

我希望这个例子可以帮到你。
