添加事件：
iv=(ImageView) findViewById(R.id.imageView1);
tbutton=(ToggleButton) findViewById(R.id.tbutton01);
checkbox=(CheckBox) findViewById(R.id.checkbox01);
radioGroup=(RadioGroup) findViewById(R.id.radiogroup01);
radioOn=(RadioButton) findViewById(R.id.raidoOn);
radioOff = (RadioButton) findViewById(R.id.raidoOff);
tbutton.setOnCheckedChangeListener(new OnCheckedChangeListener(){@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
setState(isChecked);
}
});
checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override

// TODO Auto-generated method stub
setState(isChecked);
}
});
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

setState(state);
}
});
// radioOn.setOnCheckedChangeListener(new
