一个简单的checkbox例子：

MainActivity .java

public class MainActivity extends Activity {
    private CheckBox checkbox1;
    private CheckBox checkbox2;
    private CheckBox checkbox3;
    private CheckBox checkbox4;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        checkbox1=(CheckBox)findViewById(R.id.checkbox1);
        checkbox2=(CheckBox)findViewById(R.id.checkbox2);
        checkbox3=(CheckBox)findViewById(R.id.checkbox3);
        checkbox4=(CheckBox)findViewById(R.id.checkbox4);

        checkbox1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if(isChecked){
                    setTitle(checkbox1.getText()+"被选中");
                }else {
                    setTitle(checkbox1.getText()+"取消选中");
                }
            }
        });
        checkbox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if(isChecked){
                    setTitle(checkbox2.getText()+"被选中");
                }else {
                    setTitle(checkbox2.getText()+"取消选中");
                }
            }
        });
        checkbox3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if(isChecked){
                    setTitle(checkbox3.getText()+"被选中");
                }else {
                    setTitle(checkbox3.getText()+"取消选中");
                }
            }
        });
        checkbox4.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if(isChecked){
                    setTitle(checkbox4.getText()+"被选中");
                }else {
                    setTitle(checkbox4.getText()+"取消选中");
                }
            }
        });
    }

    @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;
    }

    public void GetResult(View v){

        String result="";
        if(checkbox1.isChecked()){
            result+=checkbox1.getText()+"、";
        }
        if(checkbox2.isChecked()){
            result+=checkbox2.getText()+"、";
        }
        if(checkbox3.isChecked()){
            result+=checkbox3.getText()+"、";
        }
        if(checkbox4.isChecked()){
            result+=checkbox4.getText()+"、";
        }
        if(!"".equals(result)){
            result=result.substring(0,result.length()-1);
        }else{
            result="No one";
        }
        Toast.makeText(getApplicationContext(), result, 0).show();
    }
}
