显示图库中的图片时，应用程序崩溃
When displaying a picture from the gallery, the application breaks down
对不起我的英语。
应用程序运行正常。将文件附加到 imageview，然后将其发送到服务器。
现在，在选择图片（文件）后，应用程序将其显示在图像视图中，所有方法都正确运行并结束。
但是应用程序将我抛到上一个片段，日志中没有任何错误。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == Activity.RESULT_OK && requestCode == 100){
if(getPath(data.getData()) != null){
Uri fileUri = data.getData();
file = new File(getPath(fileUri));
String mimetype = getActivity().getContentResolver().getType(fileUri);
Log.d("mylog","name " + file.getName() + " type " + mimetype);
imageV.setVisibility(View.VISIBLE);
imageV.setImageResource(R.drawable.icons8highpriority96);
if(mimetype.equals("image/jpeg")){ imageV.setImageURI(fileUri);}
if(mimetype.equals("image/png")){ imageV.setImageURI(fileUri);}
if(mimetype.equals("application/pdf")){ imageV.setImageResource(R.drawable.icons8pdf80);}
if(mimetype.equals("text/html")){ imageV.setImageResource(R.drawable.icons8doc80);}
textFileName.setText(file.getName());
textFileName.setVisibility(View.VISIBLE);
}else {
imageV.setVisibility(View.VISIBLE);
textFileName.setVisibility(View.VISIBLE);
textFileName.setText("Выберите файл из определенного раздела! ");}
}
}
我附上一些让我困惑的日志 -

用 try 和 cath 包装你写在 onActivityResult 中的代码并打印异常
我建议你逐行调试你的代码，我认为有些东西是空的。有时在不同的 sdk 中，get Path(file Uri) 是不同的
你可以按照这个结构。用你的变量和方法替换变量和方法。希望它能帮助你。请评论任何查询。
