我将facebook sdk集成到我的应用程序中，它工作得很好，但我的问题是 当我第一次运行我的项目登录成功但用户数据没有得到它甚至数据显示在吐司但不显示在滑动抽屉。
然后我自动重启app数据集。请帮帮我这是我的代码
首先运行启动画面
Splash.java
public class Splash extends Activity {
//Give your SharedPreferences file a name and save it to a static variable
public static String PREFS_NAME = "Login";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashh);
final ImageView iv = (ImageView) findViewById(R.id.imageView);
final Animation an = AnimationUtils.loadAnimation(getBaseContext(),R.anim.rotate);
final Animation an2 = AnimationUtils.loadAnimation(getBaseContext(),R.anim.abc_fade_out);
iv.startAnimation(an);
an.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
iv.startAnimation(an2);
finish();
Intent i = new Intent(getBaseContext(),Login.class);
startActivity(i);
}
@Override
public void onAnimationRepeat(Animation animation) {
}
});
}
然后登录页面

如果登录成功，则转到MainActivity（导航抽屉）.java

如果有人帮助我，我会非常高兴。提前谢谢
