小编And*_*bie的帖子

我试图去另一个页面使用button,但它总是失败.

这是我的第一类XML及其XML:

public class FindPeopleFragment extends Fragment {
    public FindPeopleFragment(){}

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

        View rootView = inflater.inflate(R.layout.fragment_home, container, false);
        return rootView;
    }

    public void goToAttract(View v)
    {
        Intent intent = new Intent(getActivity().getApplication(), MainActivityList.class);
        startActivity(intent);
    }
}

这是我的XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerInParent="true"
    android:layout_marginBottom="48dp"
    android:onClick="goToAttract"
    android:text="Button" /></RelativeLayout>

这是我的stacktrace ..这是我使用onclicklistener时的结果

12-30 16:54:28.006: E/AndroidRuntime(992): java.lang.RuntimeException: Unable to start activity ComponentInfo{info.androidhive.slidingmenu/info.androidhive.slidingmenu.MainActivityList}: android.view.InflateException: Binary …

我正在使用Fragment,它是Fragment的一个实例,而不是DialogFragment的实例.

我做谷歌的大部分搜索结果显示了如何使用DialogFragment来拥有DatePicker.

由于Fragment和DialogFragment的类型不匹配,这在我的情况下不起作用

任何例子或想法都会有所帮助

这是片段Java代码

        public class CreateReportFragment extends Fragment {

        public CreateReportFragment(){}

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

               rootView = inflater.inflate(R.layout.activity_create_report, container, false);
               initViews();
               return rootView;
        }

        private void initViews() 
       {

         final Calendar c = Calendar.getInstance();
             year  = c.get(Calendar.YEAR);
             month = c.get(Calendar.MONTH);
             day   = c.get(Calendar.DAY_OF_MONTH);

             editTextDate.setText(new StringBuilder()
             // Month is 0 based, just add 1
             .append(year)
             .append("-")
                    .append(month + 1)
                     .append("-").append(day));

        buttonDate = (Button)rootView.findViewById(R.id.buttonDate);
        }

如何在Fragment中实现DatePicker？

这是我的Java代码

但它不起作用我不会得到我的错误.

package info.androidhive.slidingmenu;
import java.util.ArrayList;
import java.util.HashMap;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;   
import android.app.Fragment;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

public class CommunityFragment extends Fragment {


    public CommunityFragment(){}

    // Declare Variables
    JSONObject jsonobject;
    JSONArray jsonarray;
    ListView listview;
    ListViewAdapter adapter;
    ProgressDialog mProgressDialog;
    ArrayList<HashMap<String, String>> arraylist;
    static String RANK = "rank";
    static String COUNTRY = "country";
    static String POPULATION = "population";
    static String FLAG = "flag";


    @Override
    public View onCreateView(LayoutInflater …

这是侧面菜单的当前UI.

这是带有DRILL-DOWN或Expandable ListView菜单的应用程序的图像

如何为第一张图片创建相同的菜单UI？

是否有可能ListView在Fragment课堂上定制？

这是我的片段类,其中fragment_find_people只是一个空的XML:

public class FindPeopleFragment extends Fragment {

public FindPeopleFragment(){}


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

    View rootView = inflater.inflate(R.layout.fragment_find_people, container, false);

    return rootView;
}

}

现在,我已经有了一个,customListView但它只适用于Activity班级.我该怎么把它转移到Fragment？

我的listview_main xml

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:id="@+id/listmain" >

<ListView
    android:id="@+id/listview"
    android:layout_marginTop="10dp"
    android:background="@drawable/bg"
    android:divider="#9c9c9c"
    android:dividerHeight="5dp"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" /></RelativeLayout>
