Android how can I pick image from camera or gallery at the same time with one Intent

Question

Here's a implementation I found in a app named Pawoo. I can choose take photo or pick a image from system built-in gallery or third-party gallery at the same time.

I wonder how to achieve it with just one Intent. Because it seems not implements by third-party library.

Answer 1

I already know how to achieve it. Inspired by Intent to choose between the camera or the gallery in Android

The answer of qustion is not just one Intent. Simply, in my question screentshot, there's 3 actions, that's means 3 Intents. The key method is Intent.createChooser()

Here's my complete code:

public void click(View view) {
        File file = getExternalFilesDir(Environment.DIRECTORY_DCIM);
        Uri cameraOutputUri = Uri.fromFile(file);
        Intent intent = getPickIntent(cameraOutputUri);
        startActivityForResult(intent, -1);
    }

    private Intent getPickIntent(Uri cameraOutputUri) {
        final List<Intent> intents = new ArrayList<Intent>();

        if (true) {
            intents.add(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI));
        }

        if (true) {
            setCameraIntents(intents, cameraOutputUri);
        }

        if (intents.isEmpty()) return null;
        Intent result = Intent.createChooser(intents.remove(0), null);
        if (!intents.isEmpty()) {
            result.putExtra(Intent.EXTRA_INITIAL_INTENTS, intents.toArray(new Parcelable[] {}));
        }
        return result;


    }

    private void setCameraIntents(List<Intent> cameraIntents, Uri output) {
        final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        final PackageManager packageManager = getPackageManager();
        final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
        for (ResolveInfo res : listCam) {
            final String packageName = res.activityInfo.packageName;
            final Intent intent = new Intent(captureIntent);
            intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            intent.setPackage(packageName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, output);
            cameraIntents.add(intent);
        }
    }

Here's the my demo:

It's not one Intent. This dialog is a bottom sheet.
