显示ImageView的大图 [英] Display big image in ImageView

问题描述

如果我选择的大画面，如<一个href=\"http://www.google.ru/imgres?imgurl=http://www.lakeshore$p$pserve.wisc.edu/photo-gallery/bigwoods/lg/Big%2520Woods%2520Aerial,%2520Cronon,%2520DSC_8790.jpg&imgrefurl=http://www.lakeshore$p$pserve.wisc.edu/visit/bigwoods.htm&h=2000&w=3008&sz=1574&tbnid=bUYyrcldF3GAxM%3a&tbnh=93&tbnw=140&zoom=1&usg=__-V3U-FJCCA-NOTpk-Tzk4psH_68=&docid=GhTYWqNlIbdBnM&sa=X&ei=gHqFUfigHcWk4gSthoGoCQ&ved=0CEIQ9QEwBA&dur=279\"相对=nofollow>它是从画廊，并尝试在ImageView的显示它的ImageView的将不显示。

If I choose the big picture such as it is from Gallery and try display it in ImageView, the ImageView will not display it.

public class ColorViewerActivity extends Activity {

    // SKIP OTHER METHODS

    private static final int SELECT_PHOTO_REQUEST = 100;

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.open_image:
            selectImage();
            break;
        }
        return true;
    }

    private void selectImage() {
        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
        photoPickerIntent.setType("image/*");
        startActivityForResult(photoPickerIntent, SELECT_PHOTO_REQUEST);
    }

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

        switch(requestCode) { 
        case SELECT_PHOTO_REQUEST:
            if (resultCode == RESULT_OK) {
                Uri imageUri = imageReturnedIntent.getData();
                ImageView imageView = (ImageView) findViewById(R.id.imageView);
                imageView.setImageURI(imageUri);
            }
        }
    }
}

为什么？由于图片太大？

Why?? Because the image is too big?

对不起，我的英语水平。

Sorry for my English.

感谢

java.lang.OutofMemoryError：位图的大小超过VM预算
