このコードを機能させる方法を理解しようとしていますが、答えを失っています。私のコードは単なる壁紙セレクターであり、AOSP ソースから引き出されたコードです。
現在の壁紙をSDカードに保存するボタンを追加しています。次のコードがありますが、これを修正する方法がわかりません。前もって感謝します
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();
現在のエラー
The method getImage(int) is undefined for the type Gallery
