@hmaclean82 Thanks for your advice.
I have added this feature.
You can see the 1.2.1 version.

great thanks, although i'm getting this crash, I think it may be unrelated to your change, it is just noticeable now that all the objects are expanded:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int org.json.JSONArray.length()' on a null object reference at com.dandan.jsonhandleview.library.JsonViewLayout$JsonViewOnClickListener.onClick(JsonViewLayout.java:210) at android.view.View.callOnClick(View.java:6621) at com.dandan.jsonhandleview.library.JsonView.collapse(JsonView.java:118) at com.dandan.jsonhandleview.library.JsonViewLayout.operationJsonView(JsonViewLayout.java:391) at com.dandan.jsonhandleview.library.JsonViewLayout.clickAllView(JsonViewLayout.java:372) at com.dandan.jsonhandleview.library.JsonViewLayout.clickAllView(JsonViewLayout.java:381) at com.dandan.jsonhandleview.library.JsonViewLayout.clickAllView(JsonViewLayout.java:381) at com.dandan.jsonhandleview.library.JsonViewLayout.expandAll(JsonViewLayout.java:359)

Here I think you also want to protect against null in your if statement (the JSONObject.names() can return null)

JSONArray array = isJsonArray ? (JSONArray) value : ((JSONObject) value).names(); if (!isJsonArray && array.length() == 1 && "nameValuePairs".equals(array.opt(0).toString())) {

Yes, what you said is correct.
Maybe I didn't consider all the data.
Some unusual data may cause a crash.
