如何从图库中获取多张图片，并在选择后显示在LinearLayout中

// 请求权限
private static final int REQUEST_CODE_GALLERY = 100;
private static final int REQUEST_CODE_PERMISSION = 200;

private void requestPermissions() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, REQUEST_CODE_PERMISSION);
    } else {
        openGallery();
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == REQUEST_CODE_PERMISSION) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            openGallery();
        } else {
            Toast.makeText(this, "Permission denied", Toast.LENGTH_SHORT).show();
        }
    }
}

// 打开图库
private void openGallery() {
    Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    intent.setType("image/*");
    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    startActivityForResult(Intent.createChooser(intent, "Select Images"), REQUEST_CODE_GALLERY);
}

// 处理选择结果
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_GALLERY && resultCode == RESULT_OK && data != null) {
        if (data.getClipData() != null) {
            int count = data.getClipData().getItemCount();
            for (int i = 0; i < count; i++) {
                Uri imageUri = data.getClipData().getItemAt(i).getUri();
                addImageToLayout(imageUri);
            }
        } else if (data.getData() != null) {
            Uri imageUri = data.getData();
            addImageToLayout(imageUri);
        }
    }
}

// 显示图片
private void addImageToLayout(Uri imageUri) {
    ImageView imageView = new ImageView(this);
    try {
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
        imageView.setImageBitmap(bitmap);
    } catch (IOException e) {
        e.printStackTrace();
    }
    LinearLayout linearLayout = findViewById(R.id.linearLayout);
    linearLayout.addView(imageView);
}
