I need to put button into list view to go to another view.
my button: AddTime = (Button) findViewById(R.id.Add_Time);
i tryd to get it working using:
public class myclass extends ListActivity implements OnClickListener {
and i have
public void onClick(View arg0) {

and i need it to go to another place i think using this
Intent intent = new Intent(this, myclass.class);
startActivity(intent);

I suggest you to use a list view with strings. Make a buttons array and when you click on one, via onClick get the button in the array with the position parameter

How to fetch data from a custom list view with multiple radio buttons

I have gone through a lot of links here, but yet i was not able to get my stuff working. Can you please help me fetch data from my custom list.

I am populating a List through the UI the code for that is :-
package com.example.customadapter;
import java.lang.reflect.Array;

import android.support.v7.app.ActionBarActivity;
import android.content.Intent;

option2=opt2.getText().toString();
System.out.println("Questio added in the UI --> "+ question);
String statusReceived=mydata.AddingQuestions(questio_no, question, option1, option2);
Toast.makeText(getApplicationContext(), statusReceived, Toast.LENGTH_LONG).show();

});
btn_display.setOnClickListener(new OnClickListener() {
#Override

// TODO Auto-generated method stub
for (int i=0;i<mydata.myQstnList.size();i++)
{

}
Intent myIntent = new Intent(CustomAdapter.this, Mediator.class);
startActivity(myIntent);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.custom_adapter, menu);
return true;
}
#Override

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Finally i made an adapter from base adapter as follows:-

super();
this.context=context;
this.mQuestion = mQuestion;
this.mInflater = LayoutInflater.from(context);
}
#Override

ViewHolder holder;
if (convertView == null){
view = mInflater.inflate(R.layout.customized_view, parent,false);
holder = new ViewHolder();
holder.rg=(RadioGroup)view.findViewById(R.id.radioGroup_option);

view.setTag(mQuestion);
}else {
view = convertView;
holder = (ViewHolder)view.getTag();
}
Question qstnRef=mQuestion.get(position);
holder.tv_qstn.setText(qstnRef.getQstn());
holder.rb_opt1.setText(qstnRef.getOpt1());
holder.rb_opt2.setText(qstnRef.getOpt2());
holder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
//List<Question> data =(List<Question>) group.getTag();
//Toast.makeText(context,(CharSequence) data.get(checkedId).getOpt2(),Toast.LENGTH_SHORT).show();
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
RadioButton r_btn=(RadioButton)group.getChildAt(i);
if (r_btn.getId() == checkedId){
System.out.println(r_btn.getText().toString());
}
}
}
});
return view;
}
private class ViewHolder {
public TextView tv_qstn;
public RadioButton rb_opt1,rb_opt2;
public RadioGroup rg;
}
}
But i am trying to get this data that i enter in the UI, but I am not able to get this to work, please provide me assistance !!!!
The code in the current format is giving me runtime error :-
05-09 06:01:06.669: E/AndroidRuntime(2420):
java.lang.ClassCastException: android.widget.TextView cannot be cast
to android.widget.RadioButton
05-09 06:01:06.669: E/AndroidRuntime(2420): at
com.example.customadapter.MyAdapter$1.onCheckedChanged(MyAdapter.java:83)

group.getChildCount() returns 3 as it has 3 child. but 1 child is of TextView that's why you were getting java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.RadioButton
To avoid it do type checking using instanceof before typecasting.
do like this:
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
if(group.getChildAt(i) instanceof RadioButton ) { // check if child is `RadioButton`
RadioButton r_btn = (RadioButton) group.getChildAt(i);
if (r_btn.getId() == checkedId) {
System.out.println(r_btn.getText().toString());
}
}
}

Use a ListView, and assign a 9-patch drawable to each item's background which will consist of a centered dot and the vertical line.
The whole trick will be to specify the strechable regions of your nine-patch properly (stretch the line and not the dot).
Once you are happy with that, just make a different dot appearance for the active element and use an XML selector drawable to assign either the default or activated state 9 patch to the background.

As I mentioned, your problem is this call: getString(fare), which is attempting to retrieve a String resource with an id the value of fare. Judging from your code, I'm assuming that you're simply trying to display the String value of fare in a TextView, in which case change that call as follows:
String sfare = String.valueOf(fare);

You have extended ListActivity. This is a convenience class that can be used to display a single ListView. The crash is clearly described in your logcat/stacktrace:
java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'
Since your layout contains 3 ListViews, you probably can't use ListActivity anyway. Just change your activity to extend Activity and go from there.

close custom Dialog android

I created a custom dialog with spinner and OK button. I have populated this spinner with some items and inflated the layout.If I click OK button dialog will dismiss.
I set the spinner
spinner.performCLick();
is there is any way to get spinner selected item and to close the dialog without pressing OK button. I have tried
button.performclick();
but no use.

see my below code it may help you.
package com.Test_dia;
import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;
import android.widget.Toast;
public class Test_diaActivity extends Activity {
private Button btn;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
showalert();
}
});
}
protected void showalert() {
// TODO Auto-generated method stub
final Dialog dia = new Dialog(this);
dia.setContentView(R.layout.dia);
final String a[] = { "select one", "android", "java", "php" };
Button btnok = (Button) dia.findViewById(R.id.button2);
Spinner spin = (Spinner) dia.findViewById(R.id.spinner1);
btnok.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dia.dismiss();
}
});
spin.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, a));
spin.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
if (arg2 > 0) {
Toast.makeText(Test_diaActivity.this,
"You Selected :" + a[arg2], Toast.LENGTH_SHORT)
.show();
dia.dismiss();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
dia.show();
}
}
main.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="click here" />
</LinearLayout>
dia.xml
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="16dp" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/spinner1"
android:text="ok" />
This code is work for me perfectly ok.
enjoy....

EDIT (removed previous non-suitable answer)
I'm going to assume that your issue is that using setOnItemSelectedListener is firing 'onItemSelected' on startup (thus selecting the first item in the spinner without any user input) and you don't want that.
If that is the case, try the following.
Set a class variable:
private int newSpinner = 0;
Then in the setOnItemSelectedListener:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
#Override
public void onItemSelected(AdapterView<?> parent, View view,int pos, long id) {
if (newSpinner != 0) {
// Do your code thing here
dismiss();
} else {
newSpinner++
}
}
});

buttons in listview help? - android

I suggest you to use a list view with strings. Make a buttons array and when you click on one, via onClick get the button in the array with the position parameter
