android - 从 android studio 的图库中选择一张图片？

Question

有人可以告诉我问题是什么，它不起作用，所以请快速帮助我真正需要:

 imagePick.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent, "Select Contact Image"),1);
        }
    });


  public void onActivityResult(int reqCode, int resCode, Intent data)
{
    if(resCode==RESULT_OK)
    {
        if(reqCode==1) {
            imageURI=data.getData();
            iv.setImageURI(data.getData());

        }
    }
}

这对我有用。

private final static int SELECT_PHOTO = 12345;

 imagePick.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
            photoPickerIntent.setType("image/*");
            startActivityForResult(photoPickerIntent, SELECT_PHOTO);
        }
    });    

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

        // Here we need to check if the activity that was triggers was the Image Gallery.
        // If it is the requestCode will match the LOAD_IMAGE_RESULTS value.
        // If the resultCode is RESULT_OK and there is some data we know that an image was picked.
        if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK && data != null) {
            // Let's read picked image data - its URI
            Uri pickedImage = data.getData();
            // Let's read picked image path using content resolver
            String[] filePath = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
            cursor.moveToFirst();
            String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inPreferredConfig = Bitmap.Config.ARGB_8888;
            Bitmap bitmap = BitmapFactory.decodeFile(imagePath, options);
            imageView.setImageBitmap(bitmap);

             // Do something with the bitmap


            // At the end remember to close the cursor or you will end with the RuntimeException!
            cursor.close();
        }
    }
