我尝试使用Facebook SDK时遇到了问题,每次运行以下代码时似乎都会出现错误“java.lang.IllegalStateException:Activity has been destroyed”,我认为这与碎片有关,你有什么想法吗?
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
上面是错误信息,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);
}
}
}
onCreate
缺少super.onCreate(savedInstanceState);
,请将其放在if
语句之前,这样应该就可以了,我相信。 - jnthnjns
