如何将图像从路径加载到图像视图中？

Question

我在 SQLite 数据库中存储图像路径（来自图库的图像），现在加载到图像视图中...并使用此代码：

File imgFile = new File(cursor.getString(cursor.getColumnIndex("pic")));
                if (imgFile.exists()) {
                    IMG_USER.setImageBitmap(BitmapFactory.decodeFile(cursor.getString(cursor.getColumnIndex("pic"))));
                } else { Toast.makeText(this, "عکس پیدا نشد", Toast.LENGTH_LONG); }

和错误：

E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: /storage/emulated/0/DCIM/Camera/IMG_20161230_224205.jpg (Permission denied)

Answer 1

您需要访问权限，将此代码添加到 android 清单中

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

或者试试这个

Exception 'open failed: EACCES (Permission denied)' on Android
