Android 在一个活动中从gallary加载两个图像时,内存不足问题位图
我正在开发一个相框应用程序。用户可以在一帧内从gallary中选择两个图像。但每当我从gallary设置任何一个图像,然后选择其他图像应用程序崩溃时,在日志中就会显示内存不足的错误消息。 如何删除此错误Android 在一个活动中从gallary加载两个图像时,内存不足问题位图,android,bitmap,Android,Bitmap,我正在开发一个相框应用程序。用户可以在一帧内从gallary中选择两个图像。但每当我从gallary设置任何一个图像,然后选择其他图像应用程序崩溃时,在日志中就会显示内存不足的错误消息。 如何删除此错误 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCod

请帮助我嗨,请尝试下面的代码,希望它能帮助你
public static Bitmap decodeFile(File file, int width, int height)
{
try
{
//Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(file), null, o);
int scale = 1;
//The new size we want to scale to
final int REQUIRED_WIDTH = width;
final int REQUIRED_HIGHT = height;
//Find the correct scale value. It should be the power of 2.
while (o.outWidth / scale / 2 >= REQUIRED_WIDTH && o.outHeight / scale / 2 >= REQUIRED_HIGHT)
{
scale *= 2;
}
//Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(file), null, o2);
}
catch (FileNotFoundException e)
{
}
return null;
}
请使用。它满足您的要求,这可能会帮助您:使用或加载图像。它将使您的应用程序平滑,并且不会出现内存不足的问题。但我还有一个问题,我正在imageviw上的touch listener上实现。因此,rotate在此条件下不工作。请查看此url:->。它符合你的要求,你想要的
