Hi,
Thanks for the reply. I have already added the new activity or secocnd
activity in the AndroidManifest.xml file. I tried adding
getApplicationContext() in the intent. But still its not working. I am
herewith adding my code and also the AndroidManifest.xml file for
currency convertor. Could you please look in to the same and let me
know where am going wrong.
Thanks in advance,
Naina
1st activity:
package com.example.android.Convertor;
import android.view.View;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AdapterView.OnItemClickListener;
import android.content.Intent;
public class Convertor extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String[] convertors =
getResources().getStringArray(R.array.converters_array);
setListAdapter(new
ArrayAdapter<String>(this,R.layout.list,convertors));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new
Intent( getApplicationContext(),currency.class);
startActivity(intent);
}
});
}
}
2nd activity:
package com.example.android.Convertor;
import android.view.View;
import android.widget.TextView;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.content.Intent;
public class currency extends Activity {
private EditText rate;
private EditText curr;
private TextView Exchngtext;
private TextView localcurtext;
private TextView Foreincurtext;
private TextView Foreincurval;
private Button btncalculate;
private Button btnclear;
private double exchngrt = 0;
private double loclcurr = 0;
private double forgncurr = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.main);
initControls();
setResult(RESULT_OK);
finish();
}
private void initControls()
{
Exchngtext = (TextView)findViewById(R.id.Exchngtext);
rate = (EditText)findViewById(R.id.rate);
localcurtext =(TextView)findViewById(R.id.localcurtext);
curr = (EditText)findViewById(R.id.curr);
Foreincurtext =(TextView)findViewById(R.id.Foreincurtext);
Foreincurval = (TextView)findViewById(R.id.foreign);
btncalculate = (Button)findViewById(R.id.btncalculate);
btnclear = (Button)findViewById(R.id.btnclear);
btncalculate.setOnClickListener(new Button.OnClickListener() { public
void onClick (View v){ calculate(); }});
btnclear.setOnClickListener(new Button.OnClickListener() { public
void onClick (View v){ clear(); }});
}
private void calculate()
{
exchngrt=Double.parseDouble(rate.getText().toString());
loclcurr=Double.parseDouble(curr.getText().toString());
forgncurr=(exchngrt*loclcurr);
Foreincurval.setText(Double.toString(forgncurr));
Foreincurval.setEnabled(false);
}
private void clear()
{
rate.setText("");
curr.setText("");
Foreincurval.setText("");
}
}
AndroidManifest.xml file:
