I have created a BaseActivity class with navigation drawer and the other class CheckList extends the BaseActivity to have a navigation drawer.
In BaseActivity, I can change the activity to CheckList through navigation drawer.
But in CheckList. Even I can see the drawer, it is not work for changing class.
BaseActivity:
public class BaseActivity extends AppCompatActivity{
protected DrawerLayout drawerLayout;
protected ListView drawerList;
protected ActionBarDrawerToggle drawerToggle;
protected CharSequence mDrawerTitle;
protected CharSequence mTitle;
protected String[] drawer_menu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initActionBar();
initDrawer();
initDrawerList();
}
protected void initActionBar() {
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
}
protected void initDrawer() {
setContentView(R.layout.drawer);
drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
drawerList = (ListView)findViewById(R.id.left_drawer);
mTitle = mDrawerTitle = getTitle();
drawerToggle = new ActionBarDrawerToggle(
this,
drawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getSupportActionBar().setTitle(mTitle);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle(mDrawerTitle);
}
};
drawerToggle.syncState();
drawerLayout.setDrawerListener(drawerToggle);
}
protected void initDrawerList() {
drawer_menu = this.getResources().getStringArray(R.array.drawer_menu);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.drawer_list_item, drawer_menu);
drawerList.setAdapter(adapter);
drawerList.setOnItemClickListener(new DrawerItemClickListener());
}
//respond when click the ic_drawer
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
protected class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
protected void selectItem(int position) {
//Fragment fragment = null;
switch (position) {
case 0:
break;
case 1:
Intent main = new Intent();
main.setClass(getApplicationContext(), MainActivity.class);
startActivity(main);
finish();
break;
case 2:
Intent checklist = new Intent();
checklist.setClass(getApplicationContext(), CheckList.class);
startActivity(checklist);
finish();
break;
default:
break;
}
/*FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();*/
drawerList.setItemChecked(position, true);
setTitle(drawer_menu[position]);
drawerLayout.closeDrawer(drawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getSupportActionBar().setTitle(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}
}
CheckList:
public class CheckList extends BaseActivity implements OnClickListener {
Button addBtn;
ListView listView;
ArrayList<String> checkListItem;
ArrayAdapter<String> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getLayoutInflater().inflate(R.layout.checklist, drawerLayout);
addBtn = (Button)findViewById(R.id.addBtn);
listView = (ListView)findViewById(R.id.listItems);
addBtn.setOnClickListener(this);
checkListItem = new ArrayList<String>();
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, checkListItem);
listView.setAdapter(adapter);
checkListItem.add(getString(R.string.cl_passport));
checkListItem.add(getString(R.string.cl_charger));
checkListItem.add(getString(R.string.cl_camera));
registerForContextMenu(listView);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.checklist_contextmenu, menu);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
final AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
switch (item.getItemId()) {
case R.id.cl_contextmenu_delete:
checkListItem.remove(info.position);
adapter.notifyDataSetChanged();
return true;
case R.id.cl_contextmenu_edit:
AlertDialog.Builder alertDialog = new AlertDialog.Builder(CheckList.this);
alertDialog.setTitle(getString(R.string.cl_editItem));
final EditText edit = new EditText(this);
edit.setText(checkListItem.get(info.position));
edit.setSelectAllOnFocus(true);
alertDialog.setView(edit);
alertDialog.setCancelable(false);
alertDialog.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
checkListItem.set(info.position, edit.getText().toString());
adapter.notifyDataSetChanged();
}
});
alertDialog.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
alertDialog.create();
alertDialog.show();
return true;
default:
return super.onContextItemSelected(item);
}
}
#Override
public void onClick(View v) {
if(v==this.addBtn) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(CheckList.this);
alertDialog.setTitle(getString(R.string.cl_input));
final EditText checkListInput = new EditText(this);
alertDialog.setView(checkListInput);
alertDialog.setCancelable(false);
alertDialog.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
checkListItem.add(checkListInput.getText().toString());
}
});
alertDialog.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
alertDialog.create();
alertDialog.show();
}
}
}
I can't simply change the class to MainActivity in CheckList. But in BaseActivity, I can change to both MainActivity and CheckList.
Many thanks !!

This is my drawer.xml file
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Add content here -->
</FrameLayout>
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="260dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#e5e5e5"
android:dividerHeight="1dp"
android:background="#d6d6d6"/>
</android.support.v4.widget.DrawerLayout>
You're unable to click on the drawer's list items because you're inflating the CheckList Activity's layout directly into the DrawerLayout of the BaseActivity. This is causing it to be "on top" of all of the DrawerLayout's child Views, and your clicks won't propagate through to the drawer ListView underneath. Instead, you want to inflate CheckList's layout into the content_frame FrameLayout within the DrawerLayout.
In the BaseActivity class add a protected field for the FrameLayout, and initialize it just like the other Views.
public class BaseActivity extends AppCompatActivity {
protected DrawerLayout drawerLayout;
protected ListView drawerList;
protected FrameLayout contentFrame;
...
protected void initDrawer() {
setContentView(R.layout.drawer);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.left_drawer);
contentFrame = (FrameLayout) findViewById(R.id.content_frame);
...
}
}
Then change the inflate() call in CheckList as follows:
getLayoutInflater().inflate(R.layout.checklist, contentFrame);

I am writing an app, where I am combining activivties and navigation drawer, which I have never tried before. Here is the problem: when I am trying to access menu elements by clicking from MainActivity, everything works perfect and clicked elements pass on to other activities. But when I am trying to access drawer from EventActivity, which is opened with one of the fields of the drawer, it just does not respond and closes. This happens whatever field I am trying to press on drawer from EventActivity. Here is the code of both

What I've discovered is that drawer_activity is overlaying home_activity.
How can I solve it?
In onCreateDrawer you are setting a new layout, so your layout that you set in your MainActivity is not shown anymore. Here is how you can solve this:
HomeActivity:
public class HomeActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.onCreateDrawer(R.layout.home_activity);
}
}
And in your BaseActivity:
protected FrameLayout content;
protected void onCreateDrawer(final int layoutResID) {
setContentView(R.layout.activity_drawer);
content = (FrameLayout) findViewById(R.id.content_frame);
getLayoutInflater().inflate(layoutResID, content, true);
setupActionBar();
options = getResources()
.getStringArray(R.array.drawer_options);
drawerLayout =
(DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.nav_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, options));
drawerList.setOnItemClickListener(this);
setupDrawer();
}
Now the FrameLayout in your activity_drawer layout contains the layout of your HomeActivity.
I've implemented ActionBarDrawerToggle for NavigationDrawer and also used ActionBar.
How can I handle both click events because both require onOptionsItemSelected(MenuItem item) method?
Is there any other way around?
public class A1 extends AppCompatActivity implements OnItemClickListener {
String[] menu;
DrawerLayout dLayout;
ListView dList;
ArrayAdapter < String > adapter;
ActionBarDrawerToggle drawListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_a1);
menu = new String[] {
"Home", "Android", "Windows", "Linux", "Raspberry Pi", "WordPress", "Videos", "Contact Us"
};
dLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
dList = (ListView) findViewById(R.id.left_drawer);
adapter = new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1, menu);
dList.setAdapter(adapter);
dList.setOnItemClickListener(this);
dList.setSelector(android.R.color.holo_blue_dark);
drawListener = new ActionBarDrawerToggle(this, dLayout, R.drawable.ic_draw, R.string.dopen) {
#Override
public void onDrawerOpened(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle("Menu");
}
#Override
public void onDrawerClosed(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerClosed(drawerView);
}
};
dLayout.setDrawerListener(drawListener);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
public boolean onCreateOptionsMenu(Menu menu) //for actionbar
{
getMenuInflater().inflate(R.menu.actionbar, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.copy:
return showToast("Copy");
default:
return false;
}
// if(drawListener.onOptionsItemSelected(item))
// {
// return true;
// }
// return super.onOptionsItemSelected(item);
}
public boolean showToast(String message) {
Toast.makeText(getBaseContext(), message, Toast.LENGTH_SHORT).show();
return true;
}
#Override
public void onConfigurationChanged(android.content.res.Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawListener.onConfigurationChanged(newConfig);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawListener.syncState();
}
#Override
public void onItemClick(AdapterView <? > arg0, View v, int position, long id) {
selectitem(position);
dLayout.closeDrawers();
Bundle args = new Bundle();
args.putString("Menu", menu[position]);
Fragment detail = new DetailFragment();
detail.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, detail).commit();
}
public void selectitem(int position) {
dList.setItemChecked(position, true);
setTitle(menu[position]);
}
public void setTitle(String title) {
getSupportActionBar().setTitle(title);
}
}
I see you're using the latest AppCompat and stuff. Then why complicate the drawer?
Please go through this. You can make a drawer VERY quickly and easily, handle its open and close quite neatly. You don't even need the ActionBarDrawerToggle.
Cheers.
I've setup a database in android for my app however I'm stuck trying to delete a object within the database.
I'd like the button within BasicButtonsCard to delete the item that has been clicked on.
For example cardX holds data ABCD while cardY hold EFGH and on clicking the delete button on cardX, it deletes the card and its data.
Help is appreciated.
Code for input field:
public class note extends DialogFragment {
EditText memoryText, memoryTitle;
public interface NewPersonDialogListener{
void onFinishAddPersonDialog(String text, String title);
}
public note(){}
public Dialog onCreateDialog(Bundle savedInstanceState){
LayoutInflater i = getActivity().getLayoutInflater();
View rootview = i.inflate(R.layout.activity_note, null);
memoryText = (EditText)rootview.findViewById(R.id.memoryText);
memoryTitle = (EditText)rootview.findViewById(R.id.memoryTitle);
AlertDialog.Builder b = new AlertDialog.Builder(getActivity());
b.setTitle("Add New Memory");
b.setPositiveButton("Save", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
String text = memoryText.getText().toString();
String title = memoryTitle.getText().toString();
NewPersonDialogListener activity = (NewPersonDialogListener)getActivity();
activity.onFinishAddPersonDialog(text, title);
}
});
b.setNegativeButton("Cancel", null);
b.setView(rootview);
return b.create();
}

I will assume that you already have a RecyclerView with a button on each row since you didn't mention that as a problem. You should have a view holder class, and in the constructor of that class you can set up your listeners.
class Holder extends RecyclerView.ViewHolder{
public Holder(View itemView){
super(itemView);
View button = itemView.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int rowNumber = getPosition();
// call delete method here
}
});
}
public void bind(int index){
// ...
}
}
Solved the issue of deleting data from the database. Since it was contained in a cardview layout with a button all I needed to do was add a onclick listener which would do the following
dataSource.deleteMemory(model.getmemoryTitle());
dataSource.deleteMemory(model.getmemoryText());
mListView.remove(card);
I'm having an issue where my navigation drawer will not open, and for the life of me, I can't figure out what's causing it. Could someone take a look and possibly see something I'm missing?
