我有 2 个按钮:

  1. 1个按钮我可以拍照
  2. 在另一个按钮上,我可以从图库中选择图片。

问题是当我拍照时它正在显示它,但是当我拍摄另一张照片时它正在替换当前图片,但我想要的是图片彼此下方。例如,我从图库中选择 1 张图片并拍摄 2 张​​图片,我想查看 3 张图片,但找不到合适的解决方案。

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button btnCamera = findViewById(R.id.btnCamera);
    imageView = (ImageView)findViewById(R.id.imageView);
    btnTakeImg = (Button)findViewById(R.id.btnTakeImg);

    // Open camera and take picture
    btnCamera.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, 0);
        }
    });

    // Pick image from gallery
    btnTakeImg.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openGallery();
        }
    });
}

private void openGallery() {
    Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
    startActivityForResult(gallery, PICK_IMAGE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
        imageUri = data.getData();
        imageView.setImageURI(imageUri);
    }
    if(resultCode == RESULT_OK && requestCode == 0) {
        Bitmap bitmap = (Bitmap)data.getExtras().get("data");
        imageView.setImageBitmap(bitmap);
    }
}
