我正在开发一款应用来阅读Android的有效通知。到目前为止,我一直很成功,直到我得到了EXTRA_SMALL_ICON。我使用以下代码来检索应用程序图标和大图标,它们都可以正常工作。
//工作正常
Drawable appIcon = null;
try {
appIcon = getPackageManager().getApplicationIcon(packageName);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
//工作正常
Bitmap largeIcon = null;
try {
largeIcon = (Bitmap) notification.extras.getParcelable(Notification.EXTRA_LARGE_ICON);
} catch (Exception e) {
e.printStackTrace();
}
//不工作
Bitmap smallIcon = null;
try {
smallIcon = (Bitmap) notification.extras.getParcelable(Notification.EXTRA_SMALL_ICON);
} catch (Exception e) {
e.printStackTrace();
}
让SMALL_ICON抛出异常。
Key android.icon expected Parcelable but value was a java.lang.Integer. The default value <null> was returned.
W/Bundle: Attempt to cast generated internal exception:
java.lang.ClassCastException: java.lang.Integer cannot be cast to android.os.Parcelable
是的,我试图获得的通知设置了一个小图标。我做错了什么或者有没有其他方法来GT SMALL_ICON?我无法弄清楚原因。
谢谢!

尝试将其更改为此
Bitmap smallIcon = null;
try {
int id = notification.extras.getInt(Notification.EXTRA_SMALL_ICON);
} catch (Exception e) {
e.printStackTrace();
}
之后使用此
String pack = sbn.getPackageName();
Context remotePackageContext = null;
Bitmap bmp = null;
try {
remotePackageContext = getApplicationContext().createPackageContext(pack, 0);
Drawable icon = remotePackageContext.getResources().getDrawable(id);
if(icon !=null) {
bmp = ((BitmapDrawable) icon).getBitmap();
}
} catch (Exception e) {
e.printStackTrace();
}
