鉴于我想要保存到手机公共图库中特殊文件夹的位图,我尝试了这个:
public static void saveToGallery(Context context, Bitmap bitmap) {
File path = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), File.separator + "FolderForMyApp");
path.mkdirs();
File imageFile = new File(path, "image_name.png");
FileOutputStream out = null;
try {
out = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
catch (IOException e) {
Log.w(TAG, "Could not resolve file stream: " + e);
}
}
然而它实际上并没有出现在画廊中。我做错了什么?

它不会出现在图库中,因为您必须刷新图库,因此它知道新文件
var query = "select SID, age from Students where Name=\'Jason\'" + String.fromCharCode(10) +
"order by age asc";
$.ajax({
url: "http://mywebserver/query",
data: {
env: "dbserver1",
endTime: "getUTCDate()",
startTime: "dateadd(hour, -336, getUTCDate())",
text: query
},
type: "GET",
dataType: "json"
}).done(function (datum) {
});
嘲笑格式化。我在手机上。
