我有一个默认高度和宽度的图像视图,图像存储在数据库中,我想根据Imageview高度宽度缩放图像.因为我不希望它给出默认值,因为当我改变它的高度和宽度时我也必须在代码中更改它.
我试图获得ImageView的高度和宽度,但在两种情况下都返回0.
int height = ((ImageView) v.findViewById(R.id.img_ItemView)).getHeight();

即使它有默认的高度和宽度,这也会返回0
我正在尝试获取 ImageView bot 的高度和宽度,它返回 0
public class FullScreenImage extends FragmentActivity {
ImageView full_view;

int height;
@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.full_screen);
full_view = (ImageView)findViewById(R.id.full_view);
Bundle bundle=getIntent().getExtras();
byte[] image= bundle.getByteArray("image");
width = full_view.getWidth();
height = full_view.getHeight();
Bitmap theImage = BitmapFactory.decodeByteArray(image, 0, image.length);
Bitmap resized = Bitmap.createScaledBitmap(theImage,width , height, true);
full_view.setImageBitmap(resized);
}
