android - 应用程序图标在 Android 的 Intent 选择器中不可见

Question

我正在打开一个 Intent 选择器来发送一个 url

Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Text to send");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, "Complete Action using.."));

问题是应用程序的图像不可见。请参阅随附的屏幕截图。

stackoverflow 上有很多关于此问题的问题。我用于在 intentChooser 中显示带有图标的列表的代码如下 -

public void onShareClick(View v) {
        Resources resources = getResources();

        Intent emailIntent = new Intent();
        emailIntent.setAction(Intent.ACTION_SEND);
        // Native email client doesn't currently support HTML, but it doesn't hurt to try in case they fix it
        emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_native)));
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));
        emailIntent.setType("message/rfc822");

        PackageManager pm = getPackageManager();
        Intent sendIntent = new Intent(Intent.ACTION_SEND);     
        sendIntent.setType("text/plain");


        Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));

        List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
        List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();        
        for (int i = 0; i < resInfo.size(); i++) {
            // Extract the label, append it, and repackage it in a LabeledIntent
            ResolveInfo ri = resInfo.get(i);
            String packageName = ri.activityInfo.packageName;
            if(packageName.contains("android.email")) {
                emailIntent.setPackage(packageName);
            } else if(packageName.contains("twitter") || packageName.contains("facebook") || packageName.contains("mms") || packageName.contains("android.gm")) {
                Intent intent = new Intent();
                intent.setComponent(new ComponentName(packageName, ri.activityInfo.name));
                intent.setAction(Intent.ACTION_SEND);
                intent.setType("text/plain");
                if(packageName.contains("twitter")) {
                    intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_twitter));
                } else if(packageName.contains("facebook")) {
                    // Warning: Facebook IGNORES our text. They say "These fields are intended for users to express themselves. Pre-filling these fields erodes the authenticity of the user voice."
                    // One workaround is to use the Facebook SDK to post, but that doesn't allow the user to choose how they want to share. We can also make a custom landing page, and the link
                    // will show the <meta content ="..."> text from that page with our link in Facebook.
                    intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_facebook));
                } else if(packageName.contains("mms")) {
                    intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.share_sms));
                } else if(packageName.contains("android.gm")) {
                    intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(resources.getString(R.string.share_email_gmail)));
                    intent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.share_email_subject));               
                    intent.setType("message/rfc822");
                }

                intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
            }
        }

        // convert intentList to array
        LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);

        openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
        startActivity(openInChooser);       
    }

希望对你有帮助。
