Develop Reference

I have added profile activity, then added a dynamic image profile and username. After i did that, the navigation buttons are not working at all

here is my java code
that is the java code, I have added navigation profile activity then run it after retrieving the image and user name from the firebase. the navigation buttons are no more clickable
public class OwnerDrawer extends AppCompatActivity

To receive callbacks when the user taps a list item in the drawer, implement the OnNavigationItemSelectedListener and attach it to your NavigationView by calling setNavigationItemSelectedListener().
You need to attach the navigationView to listener
navigationView.setNavigationItemSelectedListener(this);
Hope this helps.

Getting error in setGridViewItemClickListener and also how can show images from drawable

I have created android app using GridView with ViewPager for images like gallery or small book which have 14 images
am showing all image from URL. i want also help that how can show my image from drawable
GridView got open successfully and i am able to launch the application.
Functionality is also working fine but when I want to open single image from GridView then my app close and showing message that app has stopped and open app again.
Please review my code and guide me how can I solve this problem. Here is my code:
public class MainActivity extends AppCompatActivity

You need to include the ImageActivity in the AndroidManifest.

I have done a similar project with you and I use this way:
private ArrayList<String> urlImage = new ArrayList<>();
Remember, add data to urlImage
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(getApplicationContext(), ShowImageActivity.class);
intent.putExtra(KEY_URL_IMAGE, urlImage);
intent.putExtra(KEY_POSITION, String.valueOf(position));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
});
In ShowImageActivity:
Intent intent = getIntent();
if (intent.getExtras() != null) {
url = (ArrayList<String>) intent.getExtras().get(KEY_URL_IMAGE);
position = Integer.parseInt(String.valueOf(intent.getExtras().get(KEY_POSITION)));
Toast.makeText(getApplicationContext(), "URL image" + url.get(position) + "position " + position, Toast.LENGTH_LONG).show();
}
final ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
viewPager.setAdapter(new PagerAdapter(getSupportFragmentManager(), url));
final ViewPager.LayoutParams layoutParams = new ViewPager.LayoutParams();
layoutParams.width = ViewPager.LayoutParams.MATCH_PARENT;
layoutParams.height = ViewPager.LayoutParams.WRAP_CONTENT;
layoutParams.gravity = Gravity.BOTTOM;
viewPager.setCurrentItem(position);
and show image from drawable
imageView.setImageResource(getImageId(view.getContext(),resourceImage));
public static int getImageId(Context context, String imageName) {
return context.getResources().getIdentifier("drawable/" + imageName, null, context.getPackageName());
}

You are passing OnItemClickListener in the place of context. You need to use the instance of the class like below.
Intent intent = new Intent(MainActivity.this, ImageActivity.class);
Note: If you use this, then it would have the instance of the class it is written in. In your code, you are using this inside an anonymous class of OnItemClickListener
Also, you need to check if you have defined your activity in the manifest file.

I can't navigate to another activity

Android Error I'm a real noob when it comes to Android Studio, and I'm trying to make it so when I click a button in IntroActivity, it will direct me to the FeaturedActivity page, which contains a list and navigation drawer, if that's important. But when I click the first time in the emulator, the app stops, and when I go back and click it again, nothing happens. I have Java Code for both activities. Could someone help me please?
<activity
android:name=".FeaturedActivity"
android:label="#string/title_activity_featured"
android:theme="#style/AppTheme.NoActionBar"></activity>
The first activity
public class IntroActivity extends AppCompatActivity {
Button ComeInButton;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intro);

The question is a little vague on the details, but taking a shot in the dark, did you register FeaturedActivity in the app manifest?
Something like:
<activity
android:name=".FeaturedActivity"
android:label="#string/title_activity_featured"
android:theme="#style/AppTheme">
should be in your AndroidManifest.xml file.
You are probably getting a nice error message in logcat, so please look there :)

I think the crash cause is where you are casting FeaturedActivity to View.OnClickListener inside FeatureActivity#onCreate(). since it does not implement View.OnClickListener, you get ClassCastException and since you do not catch this exception, then your app crashes.
EDIT I meant this line:
public class FeaturedActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
myListView.setOnClickListener((View.OnClickListener) this); // this line
}
...
}
EDIT 2 You can fix it by implementing View.OnClickListener in FeatureActivity like this:
public class FeaturedActivity extends AppCompatActivity implements
NavigationView.OnNavigationItemSelectedListener, View.OnClickListener {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
myListView.setOnClickListener(this); // cast is not needed anymore
}
#Override
protected void onClick(View v) {
// handle click
}
...
}
By the way, If you want to handle item click for ListView you should use AdapterView#setOnItemClickListener() instead so you get notified when one of the items in ListView is clicked

How to highlight the imagebutton when it is pressed

I want my imagebutton to hightlight it self, as the normal glow effect when a "normal" button is pressed. So i tried to put the image in, but then there is a "gray field" in the back of the image so i made it transparent so only the image will show but then the glow effect disappeared. Is there a solution to this? :)
please see imgur image as a example- Example image here
if it is to "hard" I can live with the gray field behind the image but is it possible then to make it green with the same highlight effect?
Should i put the code in MainActivity or my fragment java?

Put the imageView that you want to highlight above a View with bright color and set the visibility of the view equal to View.GONE. Now with your ImageButton
((ImageButton)findViewById(R.id.myImageBtn)).setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
myView.setVisibility(View.VISIBLE);
break;
}
case MotionEvent.ACTION_UP:
myView.setVisibility(View.GONE);
break;
// Your action here on button click
case MotionEvent.ACTION_CANCEL: {
myView.setVisibility(View.GONE);
break;
}
}
return true;
}
});

You can user selector drawable and have 3 different button drawables for each state. Create these file is drawables folder and add this line to button android:background="#drawable/button_selector"
button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- pressed -->

How to inflate badge counter in MenuItem using custom LayerDrawable

I was following this article. Unfortunatelly, badge isn't drawn. Of course I changed invalidateOptionsMenu method to supportInvalidateOptionsMenu method.
I was checking the log, step by step and found out that draw method in custom Drawable named BadgeDrawable is never called. Why is that?
I'm trying to use it in AppCompatActivity using Support Design Library version 23.0.1
I saw this answer but it seems to be out of date.
Is there anyone who managed to implement badger counter for MenuItem icon inside android.support.v7.widget.Toolbar?
If the way shown in the article is wrong then could you suggest other way to achieve the result as in example below?:
Here is a setup inside my application:
LayerDrawable XML ic_filter_notifications.xml:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/ic_filter_notification"
android:drawable="#drawable/ic_filter_grey600_18dp"
android:gravity="center"/>
<!-- set a place holder Drawable so android:drawable isn't null -->
<item android:id="#+id/ic_filter_badge"
android:drawable="#drawable/ic_filter_grey600_18dp">
</item>
</layer-list>
Menu that I use in the Toolbar menu_activity_main.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cobytu="http://schemas.android.com/apk/res-auto" >
<item
android:id="#+id/menu_settings"
android:orderInCategory="100"
android:title="#string/menu_settings"
cobytu:showAsAction="never"/>
<item
android:id="#+id/menu_logout"
android:orderInCategory="1000000"
android:title="#string/menu_logout"
cobytu:showAsAction="never"/>
<item
android:id="#+id/action_filter"
android:title="#string/filters"
android:icon="#drawable/ic_filter_notifications"
cobytu:showAsAction="always"/>
<item
android:id="#+id/action_location"
android:icon="#drawable/ic_map_marker_radius_grey600_18dp"
android:title="#string/location"
cobytu:showAsAction="always"/>
</menu>
This is function sets the count int for new BadgeDrawable inside UsefulFunctions class - UsefulFunctions.java:
public class UsefulFunctions {
private Context ctx;
public UsefulFunctions(Context context){
ctx = context;
}
public static void setBadgeCount(Context context, LayerDrawable icon,
int count) {
BadgeDrawable badge;
// Reuse drawable if possible
Drawable reuse = icon.findDrawableByLayerId(R.id.ic_filter_badge);
if (reuse != null && reuse instanceof BadgeDrawable) {
badge = (BadgeDrawable) reuse;
} else {
Log.d("mTAG", UsefulFunctions.class.getName()
+ " I'm creating new BadgeDrawable!");
badge = new BadgeDrawable(context);
}
badge.setCount(count);
icon.mutate();
Log.d("mTAG",
UsefulFunctions.class.getName() + " badge: " + badge.toString()
+ " count: " + count);
icon.setDrawableByLayerId(R.id.ic_filter_badge, badge);
}
}
This is the important scrap of my MainActivity where I invoke BadgeDrawable creation. I also show what's inside onCreate and in onOptionsItemSelected, may be needed - MainActivity.java:
