I'm trying to create an application with 5 buttons on the main page. For some reason the ListenerOnButton is not working and the app will close before showing xml buttons layout.
Here's my MainActivity:
public class MainListActivity extends Activity {
ImageButton news;
ImageButton weather;
ImageButton counter;
ImageButton fakoi;
ImageButton gyalia;
ImageButton uvindex;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
addListenerOnButton();
}
public void addListenerOnButton() {
news = (ImageButton) findViewById(R.id.news);
weather = (ImageButton) findViewById(R.id.weather);
fakoi = (ImageButton) findViewById(R.id.fakoi);
gyalia = (ImageButton) findViewById(R.id.gyalia);
uvindex = (ImageButton) findViewById(R.id.uvindex);
news.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent
(getApplicationContext(), MyOrasisNews.class);
startActivity(intent);
}
});
weather.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent
(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
});
gyalia.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent
(getApplicationContext(), GyaliaActivity.class);
startActivity(intent);
}
});
fakoi.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent
(getApplicationContext(), FakoiActivity.class);
startActivity(intent);
}
});
uvindex.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent
(getApplicationContext(), UvMainActivity.class);
startActivity(intent);
}
});
}
}
And this is the xml file

Any help will be appreciated.
you defined Buttons in your xml but you are trying to cast them to ImageButton. change type of your ImageButtons to Button.
You try to cast Button to ImageButton.
In your XML file change the Button to ImageButton or in your activity change the ImageButton to Button.

I am trying to apply a setOnClickListener on an EditText View in a Fragment and for some reason, It is not working, the code in the listener doesn't execute when I click on the EditText.

The fragment code:
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.add_payment_fragment, container, false);
view.findViewById(R.id.add_pay_time).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
return view;
}
Edit text needs focus to call onClick().
Solution 1
request focus when you set listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
}
});
editText.requestFocus(); //request focus
Solution 2
set on touch listener:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (MotionEvent.ACTION_DOWN == event.getAction())
Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
return false;
}
});
Solution 3
you can use onClickListener and onFocusChangeListener together:
EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showToast();//call your method
}
});
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus)
showToast();//call your method
}
});
EditText edText = view.findViewById(R.id.add_pay_time);
edText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getActivity(), "aaaa", Toast.LENGTH_LONG).show();
}
});
Use getActivity().getApplicationContext() instead
I made the shopping cart app and I use the navigation drawer and in this navigation drawer I use the shopping cart icon.
Now, When i click on the particular item. It's open in new activity but its not showing the shopping cart icon, So how will it show? So,i see the item in the cart?
ItemDetailsActivity. java (This is the .java file of this image where i am unable to see the shopping cart icon, so i am unable to see how many items add in the cart)

I am testing an app that I am in the process of making. When the application starts up, the splash screen is supposed to do a fade in/fade out animation into the login screen. When the application starts up FOR THE FIRST TIME, the animation works fine. But once I clear the application from task manager and restart it, the animation doesn't appear and it goes straight to the login screen with no animation occuring. Attached are the parts of the code dealing with the animation. If any other piece of the code is needed I will provide that as well. I just want it so the animation runs EVERY TIME the application runs.
SplashScreen.java
public class SplashScreen extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

do not use sleep() to delay starting another activity. You can do what you want like
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(SplashScreen.this,LoginActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
finish();
}
}, 3000);
this should work.
I have created custom Dialog layout. When user press on the button the dialog is shown. Android version lollipop shows me the dialog perfectly but in case of lower version than lollipop it throws me error.
Here is my code:
public class MainActivity extends AppCompatActivity {
private Button click;
private Dialog dialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
click=(Button)findViewById(R.id.click);
click.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(v.equals(click))
{
dialog=new Dialog(MainActivity.this);
dialog.setContentView(R.layout.check_in_weight_dialog);
dialog.create();
dialog.show();
}
}
});
}
And here is my custom dialog layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:padding="16dp"

android:layout_width="match_parent"
android:layout_height="0dp"

android:layout_height="wrap_content"
android:text="Check In Weight"

<LinearLayout

dialog.create();
this is for lolipop only. Remove this line
Try this way ,It works fine (Lolipop)
custom_dialog = new Dialog(this,android.R.style.Theme_Holo_Light_Dialog_MinWidth);
custom_dialog.getWindow().setBackgroundDrawable(new ColorDrawable((0xff000000)));
custom_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
custom_dialog.setCancelable(false);
custom_dialog.setContentView(R.layout.check_in_weight_dialog);
custom_dialog.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, Color.parseColor("#FFFFFF"));
custom_dialog.show();
Or Remove dialog.create();
dialog=new Dialog(MainActivity.this);
dialog.setContentView(R.layout.check_in_weight_dialog);
dialog.show();
i need to declare my Chronometer on onCreate() of my fragment because if I declare on onCreateView(), every time the ChronometerFragment is called the Chronometer is reseted.
My actual code:
ChronometerFragment.class
public class CronometroFragment extends Fragment {
Button btStart, btPause, btReset;
boolean click;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_cronometro, container,
false);
final Cronometro cronometro = (Cronometro) v.findViewById(R.id.cronometro);
click = true;
btStart = (Button) v.findViewById(R.id.btStart);
btPause = (Button) v.findViewById(R.id.btPause);
btReset = (Button) v.findViewById(R.id.btReset);
btStart.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.start();
}
});
btPause.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.pause();
}
});
btReset.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
cronometro.setBase(SystemClock.elapsedRealtime());
cronometro.stop();
}
});
return v;
}

My problem is that user cannot change fragment because this reset the Chronometer.
Please, can someone help me?
Thanks.
This question is badly formulated.. But in your onCreate, put setretaininstance(true). This should work. :-)
