Hi,
I am beginner in android development. To understand radioButton click event I have written below code to capture clickevent of radio button.Code is as below. Code is working only for first radio button press. Please suggest
package com.example.radiobuttonpress;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.RadioGroup.OnCheckedChangeListener;
import android.widget.RelativeLayout;
import android.util.Log;
public class MainActivity extends ActionBarActivity {
private static final String logTag = "MainActivity";
RadioGroup checkGroup;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(logTag,"Calling checkButtonPressed");
checkButtonPressed();
public void checkButtonPressed(){
RelativeLayout layout = (RelativeLayout)findViewById(R.id.main_container);
Log.i(logTag,"Calling getCheckedRadioButtonId");
final RadioButton rd = (RadioButton)findViewById(checkGroup.getCheckedRadioButtonId());
rd.setOnClickListener(new OnClickListener(){
public void onClick(View v){
Log.i(logTag,"Check switch value");
switch(rd.getId()){
case R.id.radio0:
Log.i(logTag,"Button 0 Pressed");
rd.setText("First Button is Pressed");
break;
case R.id.radio1:
Log.i(logTag,"Button 1 Pressed");
rd.setText("Second Button is Pressed");
break;
case R.id.radio2:
Log.i(logTag,"Button 2 Pressed");
rd.setText("Third Button is Pressed");
break;
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
