Question

在我的应用程序中，我使用Dialog片段作为启动画面。因此它将在应用启动时显示启动画面。当我在Android版本3下面的设备上运行应用程序时，它会显示“No such method error:getFragmentManager”之类的错误。我已经看到它可以通过使用getSupportFragmentManager()来解决。但是当我使用它时，Splash对话框是没有显示。请有人帮助我......谢谢你...

主要活动=＆gt;

        ft = getFragmentManager().beginTransaction(); //Here I am using getFragmentManager
    newFragment = SplashDialogFragment.newInstance();
    newFragment.show(MainActivity.ft, "dialog");

这是我的Splash Screen Fragment =＆gt;

public class SplashDialogFragment extends DialogFragment {

    private EditText mEditText;


    static SplashDialogFragment newInstance() {
        SplashDialogFragment f = new SplashDialogFragment();
        return f;
    }
    public void EditNameDialog() {
        // Empty constructor required for DialogFragment
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    
        setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme);        
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.splash_fragment, container);


        return view;
    }

    public void show(FragmentManager supportFragmentManager, String string) {
        // TODO Auto-generated method stub


    }


}

和erro log =＆gt;

Answer 1

我通过将MainActivity扩展到FragmentActivity解决了这个问题。以前它正在扩展Activity.After之后我使用了getSupportFragmentManager没有任何问题。

Answer 2

android.support.v4.app.Fragment;因为片段在API级别11中可用。请看这个链接： - http://developer.android.com/reference/android/support/v4/app/package-summary.html

和这个链接： -

java.lang.NoSuchMethodError when use getFragmentManager() with actionbarsherlock library

将支持jar文件放在libs中添加到build path文件夹中并导入类似于android.support.v4.app.Fragment，而不是之前的。希望这会对你有所帮助。

Answer 3

很明显它会在版本低于3时失败。请看一下 http://developer.android.com/tools/extras/support-library.html 您可以尝试使用兼容性jar。

在android中使用getfragmentmanager（）时“没有这样的方法错误”
