BitmapFactory：无法解码流：java.io.FileNotFoundException：

Question

我有一个arraylist存储从Firebase存储下载的所有Uri。

我将此列表传递给我的CustomAdapter，以便在ViewPager中显示所有图像，但由于以下错误而无法执行此操作：

BitmapFactory：无法解码流：java.io.FileNotFoundException：

MainActivity：

@Override
public Object instantiateItem(ViewGroup container, int position) {
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v =  inflater.inflate(R.layout.swipe,container,false);
    ImageView img = (ImageView) v.findViewById(R.id.imageView);
    Bitmap bitmap = BitmapFactory.decodeFile(list.get(position).getPath());
    img.setImageBitmap(bitmap);
    container.addView(v);
    return v;
}

CustomAdapter：

function Start-Exe
{
    param
    ( [string]$exePath, [string]$args1 )

    $returnVal = $false
    $pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = $exePath
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $args1
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    $p.WaitForExit()
    $stdout = $p.StandardOutput.ReadToEnd()
    $stderr = $p.StandardError.ReadToEnd()
    $exitCode = $p.ExitCode
    #OutputFile can be some log file, or just use write-host to pump to console
    #$stdout | Add-Content $global:OutputFile
    #$stderr | Add-Content $global:OutputFile

    return $exitCode
}
