在功能方面，我们可以打开相机并拍照，但当我们尝试保存时，它仍处于相同的状态 我遇到了这个问题。
您是否在活动的属性中使用了android:launchMode=“singleInstance”？以下是将图像保存到外部目录的功能
public static String saveImageInExternalCacheDir(Context context, Bitmap bitmap, String myfileName) {
String fileName = myfileName.replace(' ', '_') + getCurrentDate().toString().replace(' ', '_').replace(":", "_");
String filePath = (context.getExternalCacheDir()).toString() + "/" + fileName + ".jpg";
try {
FileOutputStream fos = new FileOutputStream(new File(filePath));
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fos);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
return filePath;
}
一旦检查了这一点，你就会明白了……不，我在舱单上没有。是否应添加或删除android:launchMode=“singleInstance”？是否应删除以使onActivityResult正常工作
public static String saveImageInExternalCacheDir(Context context, Bitmap bitmap, String myfileName) {
String fileName = myfileName.replace(' ', '_') + getCurrentDate().toString().replace(' ', '_').replace(":", "_");
String filePath = (context.getExternalCacheDir()).toString() + "/" + fileName + ".jpg";
try {
FileOutputStream fos = new FileOutputStream(new File(filePath));
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fos);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
return filePath;
}
