这是交易，我有一个RecycleView适配器，可以在onCreateViewHolder上扩展布局。当我尝试执行以下操作时：
Fresco的SimpleDraweeView发生错误，该错误在xml中定义。
<com.facebook.drawee.view.SimpleDraweeView
android:id="@+id/photo"
android:layout_width="match_parent"
android:layout_height="@dimen/image_nobar"
android:layout_alignParentEnd="true"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:adjustViewBounds="true"
android:contentDescription="@string/photo"
fresco:placeholderImage="@drawable/fry"
fresco:actualImageScaleType="focusCrop" />
这就是我将适配器设置为RecycleView
的方法list = new ArrayList<>();
gagInfo gi = new gagInfo();
list.add(gi.setEmpty());
recList.setAdapter(new gagAdapter(list, context));
populateRecyclerView(recList);
private void populateRecyclerView(final RecyclerView rView) {
new Thread(new Runnable() {
@Override
public void run() {
SharedPreferences prefs = getSharedPreferences(GAGS, MODE_PRIVATE);
Map<String, ?> allEntries = prefs.getAll();
list = new ArrayList<>();
JSONObject obj;
String keyObject;
Boolean first = true;
for (Map.Entry<String, ?> entry : allEntries.entrySet()) {
String entryValue = entry.getValue().toString();
keyObject = entry.getKey();
try {
JSONObject entryObject = new JSONObject(entryValue);
obj = entryObject.getJSONObject("nameValuePairs");
gagInfo gi = new gagInfo();
Log.d("JSON", "Processing... " + keyObject);
try {
gi.title = obj.getString("title");
gi.likes = obj.getString("likes");
gi.comments = obj.getString("comments");
gi.saved_date = obj.getString("saved_date");
gi.file_path = obj.getString("file_path");
gi.photoId = obj.getString("photoId");
list.add(gi);
if (first) {
runOnUiThread(new Runnable() {
@Override
public void run() {
ca = new gagAdapter(list, context);
rView.setAdapter(ca);
}
});
first = false;
} else {
runOnUiThread(new Runnable() {
@Override
public void run() {
ca.notifyItemInserted(list.size() - 1);
}
});
}
} catch (JSONException e) {
e.printStackTrace();
SharedPreferences.Editor editor = prefs.edit();
editor.remove(keyObject);
editor.apply();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
Collections.sort(list);
}
}).start();
}
我试图在我将Adapter设置为RecycleView的Activity中覆盖onResume（主要原因：从onCreate恢复以避免传递null适配器）：
@Override
protected void onResume() {
String action = getIntent().getAction();
if (action == null || !action.equals("Created")) {
Log.v("HCA", "Restart");
Intent intent = new Intent(this, HomeCardActivity.class);
startActivity(intent);
finish();
} else {
getIntent().setAction(null);
}
super.onResume();
}
这就是我在适配器中扩展布局的方法。如果失败，我也尝试重新布局。
@Override
public gagViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(viewGroup.getContext());
String card = prefs.getString("card_view", "0");
Integer layoutID;
if (card.equals("0")) {
layoutID = R.layout.card_layout;
} else {
layoutID = R.layout.card_layout_nowhitebar;
}
View itemView;
int count = 0;
int maxTries = 5;
do try { //TODO: Why LayoutInflater fails after third try?
itemView = LayoutInflater.
from(viewGroup.getContext()).
inflate(layoutID, viewGroup, false);
if (!(itemView == null)) break;
} catch (InflateException ie) {
Log.e("LayoutInflater", ie.toString());
if (++count == maxTries) throw ie;
} while (true);
return new gagViewHolder(itemView);
}
logcat的

答案 0 :(得分：2)
通过Activity（this）或（getActivity（））的Adapter构造函数传递上下文。看起来像重新加载时viewGroup上下文为空。
