Question

我正在使用以下函数从Bitmap获取Uri：

Uri GetImjUriFrmBitmapFnc(Bitmap SrcBitmapPsgVal)
{
    ByteArrayOutputStream BytAryOptVaj = new ByteArrayOutputStream();
    SrcBitmapPsgVal.compress(Bitmap.CompressFormat.PNG, 100, BytAryOptVaj);

    String ImjPthVar = MediaStore.Images.Media.insertImage(getContentResolver(), SrcBitmapPsgVal, "TmpTtl", null);
    Uri ImjBitmapUriVar = Uri.parse(ImjPthVar);
    return ImjBitmapUriVar;
}

我正在使用以下函数从Uri获取Bitmap：

Bitmap GetImjBitmapFrmImjUriFnc(Uri ImjUriPsgVaj, boolean WanDelImjPsgVab)
{
    Bitmap OptImjBitmapVar;
    try
    {
        OptImjBitmapVar = MediaStore.Images.Media.getBitmap(this.getContentResolver(), ImjUriPsgVaj);
        if(WanDelImjPsgVab) FylDelImjUsgUriFnc(ImjUriPsgVaj);
    }
    catch (IOException ErrVar)
    {
        ErrVar.printStackTrace();
        return null;
    }
    return OptImjBitmapVar;
}

void FylDelImjUsgUriFnc(Uri FylUriPsgVal)
{
    getContentResolver().delete(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            MediaStore.Images.ImageColumns.DATA + "=?",
            new String[]{FylUriPsgVal.getPath()});
}

boolean FylDelFnc(Uri FylUriPsgVal)
{
    File DelFylVaj = new File(FylUriPsgVal.getPath());
    if (DelFylVaj.exists()) return DelFylVaj.delete();
    else return false;
}

我尝试使用方法

删除创建的Uri

FylDelImjUsgUriFnc(Uri FylUriPsgVal) <br>
FylDelFnc(Uri FylUriPsgVal)

但它不起作用......

请告诉我如何删除已创建的Uri ...
