我正在尝试使用代码向用户显示我的应用评分
然而,一旦用户对应用程序进行了评级,就不应该再次显示
怎么做呢
此外,我们可以跟踪用户是否对我们的应用进行了评分,是否有针对此功能的google api,分析是否有助于跟踪应用的评分
public class AppRater {
private final static String APP_TITLE = "App Name";// App Name
private final static String APP_PNAME = "com.example.name";// Package Name
private final static int DAYS_UNTIL_PROMPT = 3;//Min number of days
private final static int LAUNCHES_UNTIL_PROMPT = 3;//Min number of launches
public static void app_launched(Context mContext) {
SharedPreferences prefs = mContext.getSharedPreferences("apprater", 0);
if (prefs.getBoolean("dontshowagain", false)) { return ; }
SharedPreferences.Editor editor = prefs.edit();
// Increment launch counter
long launch_count = prefs.getLong("launch_count", 0) + 1;
editor.putLong("launch_count", launch_count);
// Get date of first launch
Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0);
if (date_firstLaunch == 0) {
date_firstLaunch = System.currentTimeMillis();
editor.putLong("date_firstlaunch", date_firstLaunch);
}
// Wait at least n days before opening
if (launch_count >= LAUNCHES_UNTIL_PROMPT) {
if (System.currentTimeMillis() >= date_firstLaunch +
(DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) {
showRateDialog(mContext, editor);
}
}
editor.commit();
}
public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) {
final Dialog dialog = new Dialog(mContext);
dialog.setTitle("Rate " + APP_TITLE);
LinearLayout ll = new LinearLayout(mContext);
ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(mContext);
tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
tv.setWidth(240);
tv.setPadding(4, 0, 4, 10);
ll.addView(tv);
Button b1 = new Button(mContext);
b1.setText("Rate " + APP_TITLE);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
dialog.dismiss();
}
});
ll.addView(b1);
Button b2 = new Button(mContext);
b2.setText("Remind me later");
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
}
});
ll.addView(b2);
Button b3 = new Button(mContext);
b3.setText("No, thanks");
b3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (editor != null) {
editor.putBoolean("dontshowagain", true);
editor.commit();
}
dialog.dismiss();
}
});
ll.addView(b3);
dialog.setContentView(ll);
dialog.show();
}
}

此外,我们可以跟踪用户是否评价了我们的应用,是否有任何谷歌 对于此功能的api,分析可以帮助跟踪评级 一个应用程序
=>目前还没有这样的官方API!
并且SharedPreference不会有用,因为没有任何此类API可用,您可以使用它来跟踪用户是否已经评级!

您需要使用共享偏好Shared Preferences
每当用户评价您的应用时,您将布尔变量设置为true并在显示评级应用对话框之前进行检查(如果用户已经对其进行了评级)如果您的布尔变量为假,则可以要求用户对应用进行评级,否则用户已经为您的应用评分,共享偏好设置是存储数据的应用级变量,即使您关闭应用,只有当您从设备中删除应用或清除Android中的应用下的数据时,这些变量才会被销毁。
