小编Max*_*Max的帖子

我在Android的编程新和我,说我的应用程序运行的内存,这所示例我从一本书上抄,它正在与小图片的分辨率,但一个错误,当我加了几张照片具有更大的分辨率出来出现内存错误,可能是我做错了或者只是不知道我还应该使用图像,如果有人知道我应该改变什么,以便这个错误不再出现,请求帮助.谢谢期待!

};  
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final ImageView iv=(ImageView) findViewById(R.id.image1);

    Gallery gallery=(Gallery) findViewById(R.id.gallery);
    gallery.setAdapter(new ImageAdapter(this));
  gallery.setOnItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> parent, View v, int position, long id){
            Toast.makeText(getBaseContext(), "pic"+(position+1)+" selected", Toast.LENGTH_SHORT).show();

            //display the image selected
            try{iv.setScaleType(ImageView.ScaleType.FIT_CENTER);
              iv.setImageResource(imageIDs[position]);}catch(OutOfMemoryError e){
                     iv.setImageBitmap(null);
                }
        }
    });
