错误java.lang.IllegalStateException：活动已被销毁(Error java.lang.IllegalStateException: Activity has been destroyed)
错误java.lang.IllegalStateException：活动已被销毁(Error java.lang.IllegalStateException: Activity has been destroyed)
下面我一直在尝试与Facebook SDK合作，当我遇到这个问题时，每当运行下面的代码时，我似乎得到错误“java.lang.IllegalStateException：Activity has been destroyed”，我认为它有一些东西处理碎片，有什么想法？
11-02 15:24:29.212: E/AndroidRuntime(17034): FATAL EXCEPTION: main 11-02 15:24:29.212: E/AndroidRuntime(17034): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.facebooktest/com.example.facebooktest.FacebookTutorial}: java.lang.IllegalStateException: Activity has been destroyed以上是错误，下面是代码。
package com.example.facebooktest; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.view.Menu; import android.view.ViewGroup.LayoutParams; import android.widget.LinearLayout; import android.widget.TextView; import com.facebook.android.AsyncFacebookRunner; import com.facebook.android.Facebook; public class FacebookTutorial extends FragmentActivity { // --------- Facebook References ---------// private Fragment mainFragment; // application id from facebook.com/developers public static final String APP_ID = "434865303240706"; // log tag for any log.x statements public static final String TAG = "FACEBOOK CONNECT"; // permissions array private static final String[] PERMS = new String[] { "user_events" }; // facebook vars private Facebook mFacebook; private AsyncFacebookRunner mAsyncRunner; // id text view private TextView mText; public static final int LOGIN = Menu.FIRST; public static final int GET_EVENTS = Menu.FIRST + 1; public static final int GET_ID = Menu.FIRST + 2; protected void initLayout() { LinearLayout rootView = new LinearLayout(this.getApplicationContext()); rootView.setOrientation(LinearLayout.VERTICAL); this.mText = new TextView(this.getApplicationContext()); this.mText.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); rootView.addView(this.mText); this.setContentView(rootView); } // --------- Method called on create. ---------// public void onCreate(Bundle savedInstanceState) { if (savedInstanceState == null) { // Add the fragment on initial activity setup mainFragment = new Fragment(); getSupportFragmentManager().beginTransaction() .add(android.R.id.content, mainFragment).commit(); } else { // Or set the fragment from restored state info mainFragment = (Fragment) getSupportFragmentManager() .findFragmentById(android.R.id.content); } } }Below I have been trying to work with the Facebook SDK while i came upon this problem, every time that a run the below code i seem to get the error "java.lang.IllegalStateException: Activity has been destroyed", I think it has something to do with the fragments, any thoughts?

你应该像这样在你的自定义请求中扩展JsonArrayRequest：
public class MyJsonArrayRequest extends JsonArrayRequest { private Map<String, String> mPostParams; @Override protected Map<String, String> getParams() throws AuthFailureError { return mPostParams; } public MyJsonArrayRequest(String url, Map<String, String> postParams, Response.Listener<JSONArray> listener, Response.ErrorListener errorListener) { super(url, listener, errorListener); this.mPostParams = postParams; } }使用
getParams()方法，您将能够传递POST参数。Map<String, String> params = new HashMap<>(); params.put("ID", id); params.put("USER_ID", userId); MyJsonArrayRequest jsonArrayRequest = new MyJsonArrayRequest(GET_JSON_DATA_HTTP_URL, params, new Response.Listener<JSONArray>() { @Override public void onResponse(JSONArray response) { progressBar.setVisibility(View.GONE); JSON_PARSE_DATA_AFTER_WEBCALL(response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { } });另一种方法是通过URL中的GET请求传递参数。
You should extends JsonArrayRequest in your custom Request like this:
public class MyJsonArrayRequest extends JsonArrayRequest { private Map<String, String> mPostParams; @Override protected Map<String, String> getParams() throws AuthFailureError { return mPostParams; } public MyJsonArrayRequest(String url, Map<String, String> postParams, Response.Listener<JSONArray> listener, Response.ErrorListener errorListener) { super(url, listener, errorListener); this.mPostParams = postParams; } }with
getParams()method you will able to pass POST parameters.Map<String, String> params = new HashMap<>(); params.put("ID", id); params.put("USER_ID", userId); MyJsonArrayRequest jsonArrayRequest = new MyJsonArrayRequest(GET_JSON_DATA_HTTP_URL, params, new Response.Listener<JSONArray>() { @Override public void onResponse(JSONArray response) { progressBar.setVisibility(View.GONE); JSON_PARSE_DATA_AFTER_WEBCALL(response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { } });Another way is to pass parameters via GET request in URL.
