新建uri.mjava

public static String getRealPath(Context context, Uri uri)

{

String imagePath = null;

// 如果是document类型的Uri,则通过document id处理

if ("com.android.providers.media.documents".equals(uri.getAuthority()))

 

{

}

 

else if ("com.android.providers.downloads.documents".equals(uri.getAuthority()))

{

// file类型直接获取图片路径

imagePath = uri.getPath();

}

return imagePath;

}

 

public String getImagePath(Context context, Uri uri, String selection)

{

String path = null;

// 通过Uri和selection来获取真实的图片路径

Cursor cursor = context.getContentResolver().query(uri, null, selection, null, null);
