我有下面的鳕鱼:

Gallery gallery = (Gallery) findViewById(R.id.gallery1);
    selectedImage=(ImageView)findViewById(R.id.imageView1);
    gallery.setSpacing(1);
    gallery.setAdapter(new ImageAdapter(this));
     // clicklistener for Gallery
    gallery.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            // show the selected Image
            selectedImage.setImageResource(mImageIds[position]);
            // resize the selected Image

        }
    });

我很困惑如何设置selectedImage的大小,以便它们可以出现在相同大小的xml文件中。请帮助我!!以及如何在xml文件中设置其他图像的大小,以便它也具有相同的大小。谢谢

使用它:

selectedImage.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 0f));

selectedImage.setLayoutParams(new LinearLayout.LayoutParams(100dp, 100dp, 0f));
