导航菜单在Child Activity中不起作用

Question

所以我做了一个菜单课，现在我尝试扩展我的其他活动，我得到按钮，但幻灯片不在其他活动中工作，但它在左上方的apears ...以免转到代码

这是我的xml activity_navigatoin_menu

   <?xml version="1.0" encoding="utf-8"?>
    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer"
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="ar.com.puebloyreforma.pyr.NavigationMenu">



        <android.support.design.widget.NavigationView
            app:headerLayout="@layout/menuheader"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/caldroid_black"
            app:itemTextColor="@color/white"
            app:itemIconTint="@color/white"
            app:menu="@menu/drawermenu"
            android:layout_gravity="start"
            >    


        </android.support.design.widget.NavigationView>

这是我的manudrawer

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:id="@+id/noticias" android:title="Noticias" android:icon="@drawable/iconews"></item>
    <item android:id="@+id/calendario" android:title="Calendario" android:icon="@drawable/icocalen"></item>
    <item android:id="@+id/sysacad" android:title="Sysacad" android:icon="@drawable/icosysa"></item>
    <item android:id="@+id/contacto" android:title="Contacto" android:icon="@drawable/icocon"></item>
    <item android:id="@+id/reglamento" android:title="Reglamento" android:icon="@drawable/icoreg"></item>

</menu>

在这里我的活动

package ar.com.puebloyreforma.pyr;

import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;

public class NavigationMenu extends AppCompatActivity {
    private DrawerLayout mDL ;
    private ActionBarDrawerToggle mT  ;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_navigation_menu);
        mDL = (DrawerLayout) findViewById(R.id.drawer) ;
        mT = new ActionBarDrawerToggle(this  , mDL ,R.string.open , R.string.close) ;
        mDL.addDrawerListener(mT);
        mT.syncState();
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (mT.onOptionsItemSelected(item)){
            return true ;
        }
        return super.onOptionsItemSelected(item);
    }
}

这是一个孩子的活动

package ar.com.puebloyreforma.pyr;

import android.app.ActionBar;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;

import android.widget.Button;

public class PdfsActivity extends NavigationMenu {
    public String getTarget() {
        return target;
    }

    public void setTarget(String target) {
        this.target = target;
    }

    public String target ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pdfs);



        Button tt , tm , tn, reg ;
        tt = (Button)this.findViewById(R.id.tt);
        tm = (Button)this.findViewById(R.id.tm);
        tn = (Button)this.findViewById(R.id.tn);
        reg = (Button)this.findViewById(R.id.reg);

        final String pdfs[] = {"tm" ,
                "tt" ,
                "tn",
                "Ord1549"
        } ;

        tm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                setTarget(pdfs[0]);
                Intent hola = new Intent (PdfsActivity.this,ReglamentoActivity.class);
                hola.putExtra("TARGET", getTarget());
                startActivity(hola);
            }
        });



        tt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                setTarget(pdfs[1]);
                Intent hola = new Intent (PdfsActivity.this,ReglamentoActivity.class);
                hola.putExtra("TARGET", getTarget());
                startActivity(hola);
            }
        });

        tn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                setTarget(pdfs[2]);
                Intent hola = new Intent (PdfsActivity.this,ReglamentoActivity.class);
                hola.putExtra("TARGET", getTarget());
                startActivity(hola);
            }
        });
        reg.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                setTarget(pdfs[3]);
                Intent hola = new Intent (PdfsActivity.this,ReglamentoActivity.class);
                hola.putExtra("TARGET", getTarget());
                startActivity(hola);
            }
        });





    }
