私はアンドロイドアプリを開発しています。一部のデータが から取得され、アプリFirebaseDatabaseの に表示されています。RecyclerView
RecyclerViewが入っていますcards。すべてのカードに、画像とテキストが表示されます。カードには「共有」ボタンがあり、クリックするdynamic-linkと生成され、誰とでも共有されます。共有された動的リンクをクリックすると、アプリが開き、共有ボタンがクリックされたのと同じカードにあった画像が表示されますが、テキストは常に最後に保存されたデータが表示されます。あなたが私の主張を理解したことを願っています。
これが私が生成している方法ですdynamic-link：
Button btnShare = (Button) holder.itemView.findViewById(R.id.btn_share);
btnShare.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Uri BASE_URL = Uri.parse("http://www.appwebsite.com/");
holder.APP_URI = BASE_URL.buildUpon().path(imageUIDh).build();
packageName = holder.itemView.getContext().getPackageName();
deepLinkTS = Uri.parse("https://u9p25.app.goo.gl/?link="+holder.APP_URI+"&apn="+packageName+"&amv="+16+"&ad="+0);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Please help this needy: " + deepLinkTS.toString() + "\n-shared through app.");
holder.itemView.getContext().startActivity(Intent.createChooser(intent, "Share via..."));
}
});
の方法で処理dynamic-linkするonCreate()方法は次のMainActivity.classとおりです。
boolean autoLaunchDeepLink = false;
AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, MainActivity.this, autoLaunchDeepLink)
.setResultCallback(
new ResultCallback<AppInviteInvitationResult>() {
@Override
public void onResult(@NonNull AppInviteInvitationResult result) {
if (result.getStatus().isSuccess()) {
// Extract deep link from Intent
Intent intent = result.getInvitationIntent();
final String deepLink = AppInviteReferral.getDeepLink(intent);
// Handle the deep link. For example, open the linked
// content, or apply promotional credit to the user's
// account.
final ProgressDialog openingSharedRequest = new ProgressDialog(MainActivity.this);
openingSharedRequest.setMessage("Opening shared help-request...");
openingSharedRequest.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
Intent helpRequestIntent = new Intent(MainActivity.this, HelpRequestThroughDeepLink.class);
helpRequestIntent.putExtra("deepLink", deepLink);
// helpRequestIntent.putExtra("deepLinkTS", HelpRequest.deepLinkTS.toString());
// helpRequestIntent.putExtra("APP_URI", HelpRequest.ViewHolder.APP_URI.toString());
helpRequestIntent.putExtra("postedFrom", postedFromS);
// new AlertDialog.Builder(MainActivity.this)
// .setMessage(deepLink)
// .setPositiveButton("OK", null)
// .create()
// .show();
startActivity(helpRequestIntent);
openingSharedRequest.dismiss();
}
}, 1200);
// [START_EXCLUDE]
// Display deep link in the UI
// ((TextView) findViewById(R.id.link_view_receive)).setText(deepLink);
// [END_EXCLUDE]
} else {
// Log.d(TAG, "getInvitation: no deep link found.");
// Toast.makeText(getBaseContext(), "Some error occurred", Toast.LENGTH_SHORT).show();
}
}
});
// [END get_deep_link]
からのコードは次のHelpRequestThroughDeepLink.javaとおりです。

どうすればこれを達成できるか教えてください。
