我是 android 开发的新手。在我的应用程序中，我有一个显示在 ListView 中的联系人类。对于我的联系人，我有一张从图库中获得的图像，图像 uri 存储在数据库中。在我最后Post

我的问题由此 post 得到解决

我将 uses-permission android:name="android.permission.MANAGE_DOCUMENTS" 添加到 list 文件，但我仍然遇到错误。我有一个显示联系信息的 ListView 。我的联系人适配器

package com.example.sayres.myapplication7.mvp.view.adapter;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.example.sayres.myapplication7.R;
import com.example.sayres.myapplication7.entity.Contact;

import java.io.IOException;
import java.util.List;


public class ContactAdapter extends ArrayAdapter<Contact> {
private Bitmap bm;
private Context context;
private List<Contact> contacts;

public ContactAdapter(Context context, List<Contact> contacts) {
    super(context, 0, contacts);
    this.context = context;
    this.contacts = contacts;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View rootView = View.inflate(getContext(), R.layout.item_contact_list, null);

    /**
     * get reference from item_contact_list Layout
     */
    ImageView imageViewAvatar = (ImageView) rootView.findViewById(R.id.imageView_avatar);
    TextView textViewName = (TextView) rootView.findViewById(R.id.textView_name);
    TextView textViewFamily = (TextView) rootView.findViewById(R.id.textView_family);

    Contact contact = contacts.get(position);

    if (contact.getImageSrc() =="") {
        Log.d("===>", "getImageSrc() == null");
        imageViewAvatar.setImageResource(R.mipmap.ic_launcher);
    } else {

        try {
            bm = MediaStore.Images.Media.getBitmap(context.getContentResolver(), Uri.parse(contact.getImageSrc()));
            imageViewAvatar.setImageBitmap(bm);

        } catch (IOException e) {
            e.printStackTrace();
        }



    }
    Log.d("===>", "getView from DB: " + Uri.parse(contact.getImageSrc()));
    Log.d("===>", "getView: " + contact.getImageSrc());
    textViewName.setText(contact.getName());
    textViewFamily.setText(contact.getFamily());

    return rootView;

}

此错误针对此行:bm = MediaStore.Images.Media.getBitmap(context.getContentResolver(), Uri.parse(contact.getImageSrc()));

错误是什么？我该如何解决？

编辑:

这是我的联系人类:

package com.example.sayres.myapplication7.entity;

import java.io.Serializable;

public class Contact implements Serializable{
private int _id;
private String name, lastName, phoneNumber,imageSrc;

public Contact(int _id, String name, String family, String phoneNumber, String imageSrc) {
    this._id = _id;
    this.name = name;
    this.lastName = family;
    this.phoneNumber = phoneNumber;
    this.imageSrc = imageSrc;
}

public int get_id() {
    return _id;
}

public Contact set_id(int _id) {
    this._id = _id;
    return this;
}

public String getName() {
    return name;
}

public Contact setName(String name) {
    this.name = name;
    return this;
}

public String getFamily() {
    return lastName;
}

public Contact setFamily(String lastName) {
    this.lastName = lastName;
    return this;
}

public String getPhonNumber() {
    return phoneNumber;
}

public Contact setPhonNumber(String phonNumber) {
    this.phoneNumber = phonNumber;
    return this;
}

public String getImageSrc() {
    return imageSrc;
}

public Contact setImageSrc(String imageSrc) {
    this.imageSrc = imageSrc;
    return this;
}
}

最佳答案

当您从另一个应用程序获取 Uri 时，you have temporary rights to the content identified by that Uri .

如果您通过 ACTION_OPEN_DOCUMENT 获得了 Uri，您可以尝试使用 takePersistableUriPermission() 来获得对该内容的持久访问。您已经有了这方面的代码。

但是，如果您通过 ACTION_GET_CONTENT 获得了 Uri，则无法获得对内容的长期访问权。您必须立即使用内容(即，当您的进程仍在运行时)。您唯一真正的选择是将内容复制到您控制的某个文件中。您可以通过 ContentResolver 和 openInputStream() 获取由 Uri 标识的内容的 InputStream，并且您然后可以使用标准 Java I/O 从该流复制到某个文件。然后，继续使用该文件。
