android - 无法在ImageView中显示高分辨率图片

我正在制作一个想要显示高分辨率图片For.eg（1920 X 1200）的图库的应用程序。当我用高分辨率图片设置items.add(new Item("Red", R.drawable.wall1));时，它崩溃了。如何做到这一点。
请高手帮帮我。提前致谢。

 public class ImageGalleryActivity extends Activity {
    String strCategoryName = null;
    GridView gridView;
    Utils utils;
    private int columnWidth;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_image_gallery);

        Intent intent;
        intent = getIntent();
        if (intent != null) {
            strCategoryName = intent.getStringExtra("category");
        }



        gridView = (GridView) findViewById(R.id.gridView_cards);
            gridView.setAdapter(new MyAdapter(this));
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.image_gallery, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    public MyAdapter(Context context) {
        inflater = LayoutInflater.from(context);

        items.add(new Item("Red",       R.drawable.wall1));
        items.add(new Item("Magenta",   R.drawable.img10));

        }

        picture = (ImageView)v.getTag(R.id.picture);

最佳答案

添加此方法

public Bitmap decodeImage(int resourceId) {
        try {
            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeResource(getResources(), resourceId, o);
            // The new size we want to scale to
            final int REQUIRED_SIZE = 100; // you are free to modify size as your requirement

            // Find the correct scale value. It should be the power of 2.
            int scale = 1;
            while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >= REQUIRED_SIZE)
                scale *= 2;

            // Decode with inSampleSize
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize = scale;
            return BitmapFactory.decodeResource(getResources(), resourceId, o2);
        } catch (Throwable e) {
            e.printStackTrace();
        }
        return null;

    }

从适配器调用

picture.setImageBitmap((decodeImage(item.drawableId));

相反，这条线

 picture.setImageResource(item.drawableId);
