有没有办法获取系统通知的图标? 我可以通过辅助功能服务获得通知包裹。我甚至可以从中获取图标的ID,但我被困在那里。我不知道如何使用id来获取实际的位图,所以我可以显示它,因为它不是来自我的apk。
到目前为止,这是我的代码:
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
Log.d("onAccessibilityEvent");
if (event.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {
if (event.getParcelableData() instanceof Notification) {
Notification notification = (Notification) event.getParcelableData();
Log.d("ticker: " + notification.tickerText);
Log.d("icon: " + notification.icon);
Log.d("largeIcon: " + notification.largeIcon);
}
Log.d("notification: " + event.getText());
}
}
尝试使用此ID导致
android.content.res.Resources $ NotFoundException:资源ID#0x7f0200ad

所以我设法通过在RemoteViews中搜索第一个ImageView来实现这一目标
extractImage(notification.contentView);
...
private void extractImage(RemoteViews views) {
LinearLayout ll = new LinearLayout(getApplicationContext());
View view = views.apply(getApplicationContext(), ll);
drawable = searchForBitmap(view);
Log.d("Drawable: " + drawable);
}
private Drawable searchForBitmap(View view) {
if (view instanceof ImageView) {
return ((ImageView) view).getDrawable();
}
if (view instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup) view;
for (int i = 0; i < viewGroup.getChildCount(); i++) {
Drawable result = searchForBitmap(viewGroup.getChildAt(i));
if (result != null) {
return result;
}
}
}
return null;
}

看看是否有效:
String mPackageName = event.getPackageName();
Context remotePackageContext = context.createPackageContext(mPackageName, 0);
Drawable icon = remotePackageContext.getResources().getDrawable(mIcon);
