ImageView宽高的设置与获取



获取ImageView的宽高：
    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.newscar); 
    Log.i("MainActivity", "宽度："+String.valueOf(bitmap.getWidth())); 
    Log.i("MainActivity", "高度："+String.valueOf(bitmap.getHeight()));

设置ImageView的宽高：
ImageView imageView = (ImageView)findViewById(R.id.imageView); 
    //设置图片资源
    imageView.setImageResource(R.drawable.newscar); 

    //设置图片宽高
    LayoutParams params = imageView.getLayoutParams(); 
    params.height=200; 
    params.width =100; 
    imageView.setLayoutParams(params);
