android:CheckBox步骤

*CheckBox的方法：*
isChecked方法：是否选中
setChecked方法：设置方块状态
toggle方法：切换状态
setOnCheckedChangeListener方法：设置监听器

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();    }}
