Question

我的Activity上有三个imageView。在每个ImageView中，我想上传另一张图片。如果用户单击图标（image1 / image2 / image3），则会打开galery，以便用户可以选择图片将其上载到imageView上。在我的代码中，我只有一个imageView工作。

所以我的问题。如何修改onActivityResult方法以检查哪个imageView是clickt，并在其上调用setImageBitmapMethod？

这是我的代码

image1 = (ImageView)findViewById(R.id.image_three_1);
    image2 = (ImageView)findViewById(R.id.image_three_2);
    image3 = (ImageView)findViewById(R.id.image_three_3);

    image1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE);

        }
    });

    image2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE);
        }
    });

    image3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE);
        }
    });

}

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

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {


        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();


        image1.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

}

感谢小费tuteja。我制作了三个不同的结果变量（RESULT_LOAD_IMAGE1 / RESULT_LOAD_IMAGE2 / RESULT_LOAD_IMAGE3）然后我在右边的RESULT_LOAD_IMAGE1变量上设置了右图像。

这里有适合我的代码

private static final int RESULT_LOAD_IMAGE1 = 1;
private static final int RESULT_LOAD_IMAGE2 = 2;
private static final int RESULT_LOAD_IMAGE3 = 3;

protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_layout_for_three);

    //load titles from string.xml
    navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

    //load icons from string.xml
    navMenuIcons = getResources().obtainTypedArray(R.array.nav_drawer_icons);

    set(navMenuTitles, navMenuIcons);

    image1 = (ImageView)findViewById(R.id.image_three_1);
    image2 = (ImageView)findViewById(R.id.image_three_2);
    image3 = (ImageView)findViewById(R.id.image_three_3);

    image1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE1);


        }
    });

    image2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE2);
        }
    });

    image3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMAGE3);
        }
    });

}

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


    if (requestCode == RESULT_LOAD_IMAGE1 && resultCode == RESULT_OK && null != data) {


        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        image1.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

    if (requestCode == RESULT_LOAD_IMAGE2 && resultCode == RESULT_OK && null != data) {


        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        image2.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

    if (requestCode == RESULT_LOAD_IMAGE3 && resultCode == RESULT_OK && null != data) {


        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        image3.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

}
