我试图弄清楚如何使这个代码工作，我的损失为答案。我的代码只是一个壁纸选择器，代码来自AOSP源代码。将图库图像（墙纸）保存到SD卡（关闭）
即时通讯添加一个按钮，将当前壁纸保存到SD卡。我有下面的代码，并不知道如何解决这个问题。在此先感谢
View setButton2 = view.findViewById(R.id.savetosd);
setButton2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
int i = gallery.getSelectedItemPosition();
String s = (new StringBuilder(String.valueOf(getResources().getStringArray(R.array.wallpapers)[i]))).append(".jpg").toString();
String s1 (new saveToSDCard(.getImage(gallery.getSelectedItemPosition()), s);
startMediaScanner(s1);
Toast.makeText(getActivity().getApplicationContext(), "Saved to SD Card", Toast.LENGTH_SHORT).show();
电流误差
The method getImage(int) is undefined for the type Gallery

我不会解决问题阅读此代码.. – Maroun 2013-03-18 19:13:34
@ Maroun Maroun是的，我明白，它的很多简单问题的代码，我的主要问题是'方法getImage（int）未定义类型库'的按钮。问题出在String s1 – 2013-03-18 19:16:12
你只需要发布相关的代码。这将更容易帮助。 – Maroun 2013-03-18 19:16:59
