android navigation drawer doesn't want to get clicked

Question

I have this weird bug that my navigation drawer doesn't seem to realise that it is being clicked. I have searched through a lot of things and I can't seem to find an answer.

 package com.BlackSheepApps.Eventpost.activities;

    import android.app.ActionBar;
    import android.app.Activity;
    import android.content.Intent;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);

        setContentView(R.layout.drawer_layout);


        //sets the customized action bar
        actionbar = getActionBar();
        resources = getResources();
        actionbar.setBackgroundDrawable(new ColorDrawable(resources.getColor(R.color.opaque_blue)));

        //make the drawer
        drawerStrings = resources.getStringArray(R.array.drawer_categories);
        drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
        drawerList = (ListView)findViewById(R.id.left_drawer);

        drawerList.setAdapter(new AdapterNavigationDrawer(this, -1, drawerStrings));
        drawerList.setOnItemClickListener(new DrawerItemClickListener());

            }
        };

        // Set the drawer toggle as the DrawerListener
        drawerLayout.setDrawerListener(drawerToggle);

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

        registerViews();

    }

    /**

        drawerLayout.addView(childView);
    }

        @Override

                long arg3) {

            selectItem(arg2);

        }

    }

        switch(position){

        // Sync the toggle state after onRestoreInstanceState has occurred.
        drawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        drawerToggle.onConfigurationChanged(newConfig);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Pass the event to ActionBarDrawerToggle, if it returns
        // true, then it has handled the app icon touch event
        if (drawerToggle.onOptionsItemSelected(item)) {
          return true;
        }

        return super.onOptionsItemSelected(item);
    }

}

adapter:

package com.BlackSheepApps.Eventpost.adapters;

import android.content.Context;
import android.content.res.Resources;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;

import com.BlackSheepApps.Eventpost.R;

public class AdapterNavigationDrawer extends ArrayAdapter<String>{

    String[] button_names;
    Resources resources;

    public AdapterNavigationDrawer(Context context, int resource,
            String[] objects) {
        super(context, resource, objects);
        button_names = objects;
    }

    @Override
    public View getView(int pos, View convertView, ViewGroup parent){
        RelativeLayout row = (RelativeLayout)convertView;

        if(null == row){
            //No recycled View, we have to inflate one.
            LayoutInflater inflater = (LayoutInflater)parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = (RelativeLayout)inflater.inflate(R.layout.drawer_row, null);
        }

        TextView text = (TextView) row.findViewById(R.id.drawer_text);
        //ImageView image =(ImageView) row.findViewById(R.id.drawer_image);
        text.setText(button_names[pos]);

        return row;
    }



}

Layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

        <TextView
            android:id="@+id/drawer_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="23sp" 
            android:textColor="#FDFFED"
            android:layout_marginLeft="5dp"
            android:layout_marginTop="20dp"/>

</RelativeLayout>

When I try to click on a item in my drawer, the debug code doesn't show in the console, so it doesn't know that it's clicked. And for the record, I did register the activities inside my manifest....

Answer 1

On drawer Toggle you are calling, invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() which clearly states that it will call the onPrepareOptionsMenu() method. However it is not implemented and hence your Navigation Drawer is not responding to the clicks.

Implement it as,

/***
 * Called when invalidateOptionsMenu() is triggered
 */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // if nav drawer is opened, hide the action items
    boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
    menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
    return super.onPrepareOptionsMenu(menu);
}

source here.

Customize the above as per you code and requirement and it shall work. You also check the link above for a step by step tutorial on this topic. Have fun and happy coding. :)

EDIT:

Do like this, create a boolean variable isDrawerOpen and set it as below,

       public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);

            isDrawerOpen = false;
            // supportInvalidateOptionsMenu(); // creates call to
            // onPrepareOptionsMenu()
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            isDrawerOpen = true;
            // supportInvalidateOptionsMenu(); // creates call to
            // onPrepareOptionsMenu()
        }

then on your item click of Views in the drawer call closeDrawer(); method which is like below,

public void closeDrawer() {
    if (isDrawerOpen) {
        mDrawerLayout
                .closeDrawer((LinearLayout) findViewById(R.id.left_drawer));
    }
}
