Android载入图片时Out of Memory
嗯，这个经典的问题也被我遇上了，修改代码如下： imageView = (ImageView) findViewById(R.id.imageview); InputStream is = this.getResources().openRawResource(R.raw.idcard); BitmapFactory.Options option = new BitmapFactory.Options(); options.inJustDecodeBounds = true; //先设为只取图片的宽高不实际载入图片 Bitmap btp = BitmapFactory.decodeStream(is, null, options); int imageWidth = options.outWidth; int imageHeight = options.outHeight; DisplayMetrics dm = getReources().getDisplayMetrics(); //获取屏幕的分辨率 int screenHeight = dm.heightPixels; int screenWidth = dm.widthPixels; double heightRate = Math.ceil( (double)imageHeight / (double)screenHeight ); double widthRate = Math.ceil( (dobule)imageWidth / (double)screenWidth ); int shrinkRate = 0; if (heightRate > widthRate) {shrinkRate = (int) heightRate;} else { shrinkRate = (int) widthRate; } if (shrinkRate % 2 == 1 ) {shrinkRate += 1;} //缩放比例需为2的倍数 options.inJustDecodeBounds= false; //重新设置参数为不获取宽高 options.imSampleSize = shrinkRate; //设置载入图片时的缩放比例 btp...
