"I would like to have list_item's responding to click events and showing toast message..
Please Help..
THanks in Advance !!"

It may be because you are trying to perform click inside item click listener of ListView.
You can fix it by creating a custom adapter for listview. Customer ListView Adapter
After creating this custom adapter you can get the reference of description and loveBtn and perform click operation on this.
Your adapter's getView() code will be like this-
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
convertView=layoutInflater.inflate(R.layout.list_row, null);
TextView description=convertView.findViewById(R.id.eventDesc);
Button loveBtn=convertView.findViewById(R.id.loveButton);
}
description.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!TextUtils.isEmpty(mEventUrl)) {
Intent openLinkInBrowser = new Intent(Intent.ACTION_VIEW);
openLinkInBrowser.setData(Uri.parse(mEventUrl));
startActivity(openLinkInBrowser);
} else {
Toast.makeText(MainActivity.this, "Links are not provided", Toast.LENGTH_SHORT).show();
}
}
});
loveBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (status) {
Toast.makeText(MainActivity.this, "Liked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(true);
} else {
Toast.makeText(MainActivity.this, "Disliked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(false);
}
}
});
return convertView;
}

Android Popup Menu fill parent

I try set my popup menu in way to fill hole item on grid. Currently it look like on attached first picture and the next one is effect which I would like to have.
My code:
private void showPopupMenu(View view) {
// inflate menu
ContextThemeWrapper ctw = new ContextThemeWrapper(context, R.style.PopupMenu);
PopupMenu popup = new PopupMenu(ctw, view);
Menu menu = popup.getMenu();
menu.add(Menu.NONE, 1, Menu.NONE, "Remove");
menu.add(Menu.NONE, 2, Menu.NONE, "Block");
popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
popup.show();
}
Could you please point me to right direction to achieve effect from project?

Demo App for your requirment by using PopupWindow. Preview
You can add list in it or customize it according to your needs.
MainActivity
public class MainActivity extends Activity {
boolean isClicked = true;
PopupWindow popUpWindow;
RelativeLayout relative;
ImageView btnClickHere;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
relative = (RelativeLayout) findViewById(R.id.relative);
popUpWindow = new PopupWindow(this);
popUpWindow.setContentView(getLayoutInflater().inflate(R.layout.popup_design, null));
popUpWindow.getContentView().findViewById(R.id.textViewa).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "PopItemClicked", Toast.LENGTH_LONG).show();
}
});
btnClickHere = (ImageView) findViewById(R.id.imageView);
btnClickHere.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (isClicked) {
isClicked = false;
popUpWindow.setHeight(relative.getHeight());
popUpWindow.setWidth(relative.getWidth());
popUpWindow.showAsDropDown(relative, 0, -relative.getHeight());

Checkbuttons crashes app when checked

I created a list of checkboxes, and I was trying to increase an int value proportionally to the number of the selected ones. Instead, every time I try to check them (through .isChecked()) the app crashes. I've tried to search everywhere for some solutions, but nothing worked. I really can't understand where is the problem.
Here's the code

Java file
package com.example.deadlybanana.myfirstapp;
public class DisplayPicture extends AppCompatActivity {
List<Boolean> checkboxes = new ArrayList<Boolean>();
CheckBox press1;
CheckBox press2;
CheckBox press3;
CheckBox press4;
CheckBox press5;
int points = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_picture);
Intent intent = getIntent();
String name = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
CheckBox press1 = (CheckBox)findViewById(R.id.checkbox1);
CheckBox press2 = (CheckBox)findViewById(R.id.checkbox2);
CheckBox press3 = (CheckBox)findViewById(R.id.checkbox3);
CheckBox press4 = (CheckBox)findViewById(R.id.checkbox4);
CheckBox press5 = (CheckBox)findViewById(R.id.checkbox5);
TextView NameString = (TextView) findViewById(R.id.frasenome);
String phrase = name + ", are you some of these things?";
NameString.setText(phrase);
}
public void checkbutton(View view){
if (press1.isChecked()){
points += 4;
}
if (points > 3){
Toast.makeText(this, "You are a unicorn", Toast.LENGTH_LONG).show();
} else{
Toast.makeText(this, "You are not a unicorn", Toast.LENGTH_LONG).show();
}
}
}
(right now it is being examined just the first checkbox to simplify the code)

Try this: in onCreate()
press1 = (CheckBox)findViewById(R.id.checkbox1);
press2 = (CheckBox)findViewById(R.id.checkbox2);
press3 = (CheckBox)findViewById(R.id.checkbox3);
press4 = (CheckBox)findViewById(R.id.checkbox4);
press5 = (CheckBox)findViewById(R.id.checkbox5);
error occurs as press1.isChecked() is refers to the global CheckBox press1;
which is not yet initialized..
AS you are initializing the checkbox like:
CheckBox press1 = (CheckBox)findViewById(R.id.checkbox1); inside onCreate() which only gives it a local instance which is not accessable in your checkbutton(View view) function
Solution
remove the local initialization just use: press1 = (CheckBox)findViewById(R.id.checkbox1);

Set id for your button lets assume it be button and add the following code
Button btn = (Button)findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
checkbutton();
}
});
Note:remove the view parameter
Implementing Listeners is the best way to handle the events

I never use the method isChecked() because it never works for me. Do you want to increase the points when you select a checkbutton and maybe show the points when you press a button?
Here is the class code:
public class ButtonActivity extends AppCompatActivity
{
int points=0;
boolean check1=false;
boolean check2=false;
boolean check3=false;
boolean check4=false;
boolean check5=false;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_button);
findViewById(R.id.button).setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Toast.makeText(getApplicationContext(),points+"",Toast.LENGTH_SHORT).show();
}
});
}
public void onClick(View view)
{
switch(view.getId())
{
case R.id.checkBox:
if(check1)
{
check1=false;
points--;
}
else
{
check1=true;
points++;
}
break;
case R.id.checkBox2:
if(check2)
{
check2=false;
points--;
}
else
{
check2=true;
points++;
}
break;
case R.id.checkBox3:
if(check3)
{
check3=false;
points--;
}
else
{
check3=true;
points++;
}
break;
case R.id.checkBox4:
if(check4)
{
check4=false;
points--;
}
else
{
check4=true;
points++;
}
break;
case R.id.checkBox5:
if(check5)
{
check5=false;
points--;
}
else
{
check5=true;
points++;
}
break;
}
}
}
Here is the layout code:

null pointer exception on radio group

I am trying to make a popup window in an activity. The popup window shows up when we click a button in the activity. The layout for popup window is to show a radio group containing 4 radio buttons, a button and a seek bar and has to return a value to the main activity based on the selected radio button when the button in the pop up window is pressed.
When i run the app and open the pop up window it is giving we this error:
"java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.RadioGroup.setOnCheckedChangeListener(android.widget.RadioGroup$OnCheckedChangeListener)' on a null object reference "

You seem to be inflating the wrong layout. Change the correct layout.xml in
setContentView(R.layout.activity_custom_menu);

hide layout checkbox is checked android

I am trying to simply hide a linear layout if a checkbox is clicked. I have defined function and onClick attribute calls it which is also tested with toast but when I try hiding the layout, it doesn't do anything.
The layout.xml:
<CheckBox
android:id="#+id/cbguest"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.9"
android:onClick="itemClicked"
/>
In MainActivity.java
int[] i = {0};
public void itemClicked(View v) {
LinearLayout layoutguest1 = (LinearLayout) findViewById(R.id.guestlayout);
if (lns[0]%2 == 0) {
Toast.makeText(getApplicationContext(),"Visible", Toast.LENGTH_SHORT).show();
layoutguest1.setVisibility(View.VISIBLE);
lns[0]+=1;
}
if (lns[0]%2 != 0) {
layoutguest1.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(),"Gone", Toast.LENGTH_SHORT).show();
lns[0]+=1;
}

setContentView(R.layout.activity_main);
chkBox = (CheckBox) findViewById(R.id.chkBox);

chkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked)
{
// TODO Auto-generated method stub
if(isChecked)
{
layoutLogin.setVisibility(View.GONE);
chkBox.setText("UnHide");

else

You should be using onCheckedChangeListener as I don't think it registers as an onClick- but an onCheck.
