您好我想知道如何讓應用程序顯示特定於設備當前日期的圖像。因此,如果是1月1日,它將顯示該日期的相應圖像,如果是3月5日,則顯示3月5日的圖像。我如何使圖像顯示在Android設備上的特定日期
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
public class WidgetIntentReceiver extends BroadcastReceiver {
private static int currentImage = 0;
int[] images = {R.drawable.j_1, R.drawable.j_2,R.drawable.j_3,R.drawable.j_4,
R.drawable.j_5, R.drawable.j_6, R.drawable.j_7, R.drawable.j_8,

所以你要讀取的圖像的EXIF數據,如拍攝日期? – nikis
你可以分享一些代碼,看看你已經嘗試過嗎? – Merlevede
你想要在你的應用中顯示這個圖像,或者你想創建一個彈出窗口或小部件? –
