推荐答案

只需使用 chk1.toggle() onClick the button 取消选中的.

Just use chk1.toggle() onClick of the button to uncheck the checked ones.

public class TestCheckBoxActivity extends Activity {
  /** Called when the activity is first created. */
     CheckBox chk1, chk2;

        @Override
        public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        chk1 = (CheckBox)findViewById(R.id.checkBox1);
        chk2 = (CheckBox)findViewById(R.id.checkBox2);

        Button btn = (Button)findViewById(R.id.button1);

        btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            if(chk1.isChecked()){
                chk1.toggle();
            }

            if(chk2.isChecked()){
                chk2.toggle();
            }

        }
    });
       }
}
