Android 将相机图像的路径保存到SQLite表中并检索它

我正在尝试从当前活动切换到相机活动以拍摄照片，在那里我希望将捕获图像的路径保存到SQLite表中，以便检索路径并在任何活动中显示图片

1-如何保存图像的路径

2-如何从其路径显示图像

以下是我如何称之为相机活动： “我还是有同样的问题……有什么建议吗？”

在活动的

onActivityResult（）

要显示此图像，只需使用intent

// Here imagePath is from database
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(imagePath), "image/*");
startActivity(intent);

请检查新发布的代码。不幸的是，拍照后应用程序崩溃。

// store this string in database..
String imagePath = data.getData().toString();

// Here imagePath is from database
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(imagePath), "image/*");
startActivity(intent);
