如何捕获 3 张图像并在 3 diff imageview 中显示

Question

我有 3 个 Imageview。我只想在 android 中捕获 3 个图像并分别显示在 3 个 imageview 中。

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.imageView = (ImageView)this.findViewById(R.id.imageView1);
        this.imageView1 = (ImageView)this.findViewById(R.id.imageView2);
        this.imageView2 = (ImageView)this.findViewById(R.id.imageView3);

        Button photoButton = (Button) this.findViewById(R.id.button1);
        Button photoButton1 = (Button) this.findViewById(R.id.button2);
        Button photoButton2 = (Button) this.findViewById(R.id.button3);

        photoButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }
        });
    }

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
            Bitmap photo = (Bitmap) data.getExtras().get("data");
            imageView.setImageBitmap(photo);
        }
    }

}

这是我的代码，但我无法在三个 diff 图像视图上设置图像 我的想法是在三个按钮上打开相机并在各自的图像视图上显示图像

为每个图像使用不同的请求代码：

photoButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, 1);
        }
    });
photoButton1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, 2);
        }
    });

在 Activity 结果集中根据结果设置不同的图像视图：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1 && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        imageView.setImageBitmap(photo);
    }
    if (requestCode == 2 && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        imageView1.setImageBitmap(photo);
    }


}
