在将其保存到应用程序之前检索捕获的图像

Question

刚接触Android，我想知道如何检索从相机中捕获的图像（我的应用程序通过意图调用它）。

Answer 1

请试试这个

String path =   "File path";
File file = new File(path);
Uri outputFileUri = Uri.fromFile( file );
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri );
startActivityForResult( intent, 0 );

Answer 2

answer from Sandy是正确的，但我想添加更多内容，我试图在他的回答中进行编辑，但不能这样发布

String path =   "File path"; 
File file = new File(path); 
Uri outputFileUri = Uri.fromFile( file ); 
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); 
intent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri ); 
startActivityForResult( intent, 101 ); 

您可以在onActivityResult()方法中查看上面指定的路径中拍摄的新图像，也不要忘记放置if() condition to check the resultCode is Ok or not。像这样，

if (requestCode == 101 && resultCode == Activity.RESULT_OK) { 
  //get Image back from the path like BitmapFactory.decodeFile(path);            
}
