相关文章：Android手机读取相册图片，根据URI获取图片路径

从图库获取的Uri：content://media/external/images/media/20782

Uri uri = data.getData();

获取图片的本地路径：/storage/emulated/0/DCIM/Camera/IMG_20181106_142017.jpg

获取方法，将上述的URI传入：

path = getRealFilePath(HnUiUtils.getContext(), uri); //拿到图片

public static String getRealFilePath(final Context context, final Uri uri) {

if (null == uri)

return null;

final String scheme = uri.getScheme();

String data = null;

if (scheme == null)

data = uri.getPath();

else if (ContentResolver.SCHEME_FILE.equals(scheme)) {

data = uri.getPath();

} else if (ContentResolver.SCHEME_CONTENT.equals(scheme)) {

Cursor cursor = context.getContentResolver().query(uri,

new String[]{MediaStore.Images.ImageColumns.DATA}, null, null, null);

if (null != cursor) {

if (cursor.moveToFirst()) {

int index = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);

if (index > -1) {

data = cursor.getString(index);

}

}

cursor.close();

}

}

return data;

}

删除方法：

//删除图库照片

private boolean deleteImage(String imgPath) {

ContentResolver resolver = this.getContentResolver();

Cursor cursor = MediaStore.Images.Media.query(resolver, MediaStore.Images.Media.EXTERNAL_CONTENT_URI,

new String[]{MediaStore.Images.Media._ID}, MediaStore.Images.Media.DATA + "=?",

new String[]{imgPath}, null);

boolean result = false;

if (null != cursor && cursor.moveToFirst()) {

long id = cursor.getLong(0);

Uri contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

Uri uri = ContentUris.withAppendedId(contentUri, id);

HnLogUtils.e("--deleteImage--uri:" + uri);

int count = this.getContentResolver().delete(uri, null, null);

result = count == 1;

} else {

File file = new File(imgPath);

result = file.delete();

}

HnLogUtils.e("--deleteImage--imgPath:" + imgPath + "--result:" + result);

return result;

}
