Radio Group Onclick Event Not Firing, How Do I Tell Which Is Selected?

I'm using radio group but RadioGroup onClick event is not firing and the method getCheckedRadiobuttonID() is returning null. Here is the element in my layout:

Solution 1:

This problem can be solved using the following

RadioGrouprg= (RadioGroup) findViewById(R.id.radioGroup1);
        rg.setOnCheckedChangeListener(newOnCheckedChangeListener()
        {
            @OverridepublicvoidonCheckedChanged(RadioGroup group, int checkedId)
            {
                switch(checkedId)
                {
                case R.id.radio0:
                    // TODO Somethingbreak;
                case R.id.radio1:
                    // TODO Somethingbreak;
                case R.id.radio2:
                    // TODO Somethingbreak;
                }
            }
        });

Alternatively

You can use custom ids rather than default one

RadioGrouprg= (RadioGroup) findViewById(R.id.radioGroup1);
            rg.setOnCheckedChangeListener(newOnCheckedChangeListener()
            {
                @OverridepublicvoidonCheckedChanged(RadioGroup group, int checkedId)
                {
                    switch(checkedId)
                    {
                    case R.id.male:
                        // TODO Somethingbreak;
                    case R.id.female:
                        // TODO Somethingbreak;
                    case R.id.other:
                        // TODO Somethingbreak;
                    }
                }
            });

Solution 2:

Actually I think you do not need to add android:clickable="true" or click listener. You can declare RadioGroup.OnCheckedChangeListener which will listen for change of the selection. Please see this thread for example how you can use that.

Solution 3:

EDIT : I did some changes in your code and its working for me. onClick works for all the views. Here in your code, Rgroup's width is wrap_content, so if you have put RadioButtons inside the RG (which will completely overlap the RG), your clicks would be consumed by the RadioButtons (and not the Rgroup). I made the Rgroup's width to fill_parent and the click was getting executed. Here is my sample so that you can try it out.

<RadioGroupandroid:onClick="onRGClick"ndroid:text="RadioButton"android:id="@+id/radioGroup1"android:layout_width="fill_parent"android:layout_height="wrap_content"><RadioButtonandroid:text="RadioButton"android:id="@+id/radioButton2"android:layout_width="wrap_content"android:layout_height="wrap_content"></RadioButton></RadioGroup>

And here is the Activity:

publicclassHelloextendsActivity {
    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

     }
    publicvoidonRGClick(View v){
        Toast.makeText(this, "Test ", Toast.LENGTH_LONG).show();

    }

Just click anywhere to the right of the RadioButton, and you will see the Toast. Although for general purposes,OnCheckedChangeListener is more useful. Hope this helps you.

Solution 4:

The other way is to assign your method to onClick property of each RadioButton. Then check for the view id. For instance,

publicvoidonRGClick(View v){
    int id = view.getId();
    if (id == R.id.radioButtonId) {
        //Do something
    }
}
