Question

我目前正在Android中开发一个应用程序我想为用户提供一些功能来评估当前的应用程序。它们将是一个按钮，它会点击它会询问是否用户想要评价应用程序？如果是，将在设备上进行市场应用以评估申请（市场应该显示这个应用程序。）或者它将打开浏览器，这将加载市场＆amp;显示此应用程序。之前任何人都使用过这种功能。请提供一些帮助。

谢谢。

Answer 1

我总是使用像这样的方法：

private void launchMarket() {
    Uri uri = Uri.parse("market://details?id=" + getPackageName());
    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
    try {
        startActivity(goToMarket);
    } catch (ActivityNotFoundException e) {
        Toast.makeText(this, R.string.couldnt_launch_market, Toast.LENGTH_LONG).show();
    }
}

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();        
}}

现在将课程集成到您的活动中 - ＆gt;

AppRater.app_launched(this);

Answer 3

这是一个简单的解决方案：

最终字符串appPackageName =“ com.name.app”;

private void launchMyMarket() {
    Uri uri = Uri.parse("market://details?id=" + getPackageName());
    Intent myAppLinkToMarket = new Intent(Intent.ACTION_VIEW, uri);
    try {
        startActivity(myAppLinkToMarket);
    } catch (ActivityNotFoundException e) {
        Toast.makeText(this, " unable to find source market app! try again", Toast.LENGTH_LONG).show();
    }
}

Answer 4

如果您的手机上有多个市场应用程序，则此处的答案不会直接将您带到Playstore。相反，它将显示一个选择器对话框。

要直接打开Playstore，请使用以下方法：

private fun rateUs() {
    val uri = Uri.parse("https://play.google.com/store/apps/details?id=" + activity?.packageName.toString() + "")
    val intent = Intent(Intent.ACTION_VIEW, uri)
    startActivity(intent)
}

使用应用程序对其进行评级
