How to Choose Radio Button Value using Java Android?

How to Choose Radio Button Value using Java Android? - java

If i'm click OK how to choose pick a value one service in radio button but different value.
void OpenDialogService() {
closeLyt.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
cancelTxt.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
okTxt.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
dialog.dismiss();
Bundle b = activity.getIntent().getExtras();
if(b == null)
b = new Bundle();
b.putString("service_id", "1");
startActivity(new Intent(activity, Step1.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP).putExtras(b));
overridePendingTransition(R.anim.push_left_in,R.anim.push_left_out);
}
});
dialog.show();
}
In this line for primary service :
b.putString("service_id", "1")
How i make conditional if service other give value :
b.putString("service_id", "2")

This is code snippet how you can achieve this with the help of RadioGroups
Your dialog layout should look like this :-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView

And you can inflate this layout in custom dialog box and with the help of radio buttons you can choose service type
int serviceNumber = 0;
void OpenDialogService() {
final Dialog dialog = new Dialog(this);
dialog.getWindow();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.pop_new_order2);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(true);
TextView headerTxt = (TextView) dialog.findViewById(R.id.headerTxt);
TextView okTxt = (TextView) dialog.findViewById(R.id.okTxt);
TextView cancelTxt = (TextView) dialog.findViewById(R.id.cancelTxt);
TextView primaryTxt = (TextView) dialog.findViewById(R.id.primaryTxt);
TextView otherTxt = (TextView) dialog.findViewById(R.id.otherTxt);
TextView primaryContentTxt = (TextView) dialog.findViewById(R.id.primaryContentTxt);
LinearLayout closeLyt = (LinearLayout) dialog.findViewById(R.id.closeLyt);
// Radio Buttons
final RadioGroup radio = (RadioGroup) dialog.findViewById(R.id.radioGroup1);
radio.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
View radioButton = radio.findViewById(checkedId);
int index = radio.indexOfChild(radioButton);
Toast.makeText(getApplicationContext(), "service" +index, 500).show();
serviceNumber = index+1;
}
});
headerTxt.setText("Pick Services");
//TODO change color here
// headerTxt.setBackgroundResource(R.drawable.bg_dialog_header_success);
// closeLyt.setBackgroundResource(R.color.selector_close_alert_dialog_success);
closeLyt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
cancelTxt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
okTxt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
Bundle b = getIntent().getExtras();
if (b == null)
b = new Bundle();
b.putString("service_id", String.valueOf(serviceNumber));
Toast.makeText(getApplicationContext(), "service " + String.valueOf(serviceNumber), 500).show();
//TODO Handle Activity Transition Here
// startActivity(new Intent(MainActivity.this,
// Step1.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP).putExtras(b));
// overridePendingTransition(R.anim.push_left_in,
// R.anim.push_left_out);
}
});
dialog.show();
}
Result

You can get the selected item id of RadioGroup using, radioGroup.getCheckedRadioButtonId() and use if-else to choose different strings.
int id = radioGroup.getCheckedRadioButtonId();
if(id == radioButton1)
{
b.putString("service_id", "1");
}
else if(id == radioButton1)
{
b.putString("service_id", "2");
}

setOnClickListener not working in fragment Android

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 xml:
<?xml version="1.0" encoding="utf-8"?>

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

Focus changes to listview once i clear the Edittext

I'm using broadcast receiver to show a dialog.So the flow of code is something like:
Step1 Getting the requestCode value
Step2 Based on this requestCode the broadCast receiver goes to if or else if or else part
Step3 If the value that i entered using some scanner into the EditText(i.e Scan) doesn't matches it shows a Toast "Item Not Available".
Step 4 Once "Item Not Available" toast comes the focus changes to the Listview which is my problem.
Step5 Again if i pass value to the Scan EditText the Listview get click automatically.
So my question is "How to remove focus from the Listview" and set it to the EditText(i.e Scan).
For Reference I'm attaching the snap with code snippet and the layout.xml.Please have a look and drop your suggestions why the focus is going to the listview.

Add a textwatcher to edit text and check when text is not blank and it is not equal to expected text then only switch the focus.
/* Set Text Watcher listener */
yourEditText.addTextChangedListener(passwordWatcher);
and check for text once user enter text
private final TextWatcher passwordWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void afterTextChanged(Editable s) {
if (s.length() != 0 && passwordEditText.getText().equals("Your expected text")) {
// show your toast and change focus
}
}
}

You should make your listview not focusable by using setFocusable(false) when not required and when you get response correctly from barcode scanner then you can again make your listview focusable.

Outputting in different layout

I'm currently developing an mobile grocery app. I just want to ask you why my code in layout Y cant throw the details from different activity, but layout X can! As you can see, I used checkbox to checked all items you want to purchase, but in Layout Y, if u checked the item you want and click the "add to cart" button it crashed.
Tho I reedit the code based on respective information and copy to layout Y.
Here is my Code
Baby Diaper (Layout X) Java
public class Baby_Diaper extends ActionBarActivity {
ArrayList<String> selection = new ArrayList<String>();
TextView final_text;
Button addtoCart;
Intent i = new Intent(this, Shopping_List.class);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_baby__diaper);
addtoCart = (Button) findViewById(R.id.addtocart);
final_text = (TextView)findViewById(R.id.final_shopping_diaper);
}
public void SelectItem (View view) {
boolean checked = ((CheckBox) view) .isChecked();
switch (view.getId())
{
case R.id.pampers:
if(checked)
{selection.add("Pampers");}
else
{
selection.remove ("Pampers");
}
break;
case R.id.huggies:
if(checked)
{selection.add("Huggies");}
else
{
selection.remove ("Huggies");
}
break;
case R.id.johnsons:
if(checked)
{selection.add("Johnsons");}
else
{
selection.remove ("Johnsons");
}
break;
case R.id.supreme:
if(checked)
{selection.add("Supreme");}
else
{
selection.remove ("Supreme");
}
break;
}
}
public void ocaddtocart(View view){
String final_shopping_selection = "";
for (String Selections : selection){
final_shopping_selection = final_shopping_selection + Selections + "\n";
}
final_text.setText(final_shopping_selection);
final_text.setEnabled(true);}
public void ocgtshoppinglist (View view){
Intent x = new Intent(Baby_Diaper.this, Shopping_List.class);
x.putExtra("items", final_text.getText().toString());
startActivity(x);
}

When I clicked the link on Logcat it pointed me to
final_text.setText(final_shopping_selection); of layout Y

try to change it in Y
addtoFood = (Button) findViewById(R.id.addtocart);
final_text = (TextView)findViewById(R.id.final_shopping_food);
setContentView(R.layout.activity_baby__food);
to
setContentView(R.layout.activity_baby__food);
addtoFood = (Button) findViewById(R.id.addtocart);
final_text = (TextView)findViewById(R.id.final_shopping_food);
I think your text view is null in addtocart method.

nullpointerexception upon setOnClickListener

I have a button that brings up a dialog with an OK button, and I'm getting a nullpointerexception when I click on the OK button. Does anyone know what's wrong?
Here's my java code.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylist);
myListView = (ListView)findViewById(R.id.list);
new GetStuff().execute();
Button importButton = (Button)findViewById(R.id.doButton);
importButton.setEnabled(false);
importButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
final Dialog pwdDialog = new Dialog(context);
pwdDialog.setContentView(R.layout.pwdentry);
pwdDialog.setTitle("Enter password");
TextView pwdText = (TextView)pwdDialog.findViewById(R.id.pwdText);
pwdText.setText("Enter password");
Button okBut = (Button)findViewById(R.id.okBut);
okBut.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pwdDialog.dismiss();
}
});
pwdDialog.show();
}
});
}
Here's the XML file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/pwdText"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Enter password"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="#+id/pwdEntry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="#+id/pwdText"
android:ems="10"
android:inputType="numberPassword" >
<requestFocus />
</EditText>
<Button
android:id="#+id/okBut"
style="?android:attr/buttonStyleSmall"
android:layout_width="100px"
android:layout_height="wrap_content"
android:layout_below="#+id/pwdEntry"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:text="OK" />
</RelativeLayout>
Thanks!

The problem is okBut will be null
Button okBut = (Button)findViewById(R.id.okBut);
you need to make this as
Button okBut = (Button)pwdDialog.findViewById(R.id.okBut);

Here you are retrieving a Button by using the id, R.id.okBut from your main layout R.layout.mylist.
Button okBut = (Button)findViewById(R.id.okBut);
