Android 之 复选框(CheckBox)的使用

1.调用setOnCheckedChangeListener()方法，并把 CompoundButton.OnCheckedChangeListener实例作为参数传入
2.在CompoundButton.OnCheckedChangeListener的onCheckedChanged()方法里，取得被选中复选框的实例

  /** Called when the activity is first created. */
	private CheckBox c1,c2 ;
	private Button button;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        c1 = (CheckBox) findViewById(R.id.CheckBox01);
        c2 = (CheckBox) findViewById(R.id.CheckBox02);
        button = (Button) findViewById(R.id.Button01);
        
        //注册事件监听
        c1.setOnCheckedChangeListener(new CheckBoxListener());
        c2.setOnCheckedChangeListener(new CheckBoxListener());
        button.setOnClickListener(new ButtonClickListener());
        
    }
    
    //定义事件
    class CheckBoxListener implements OnCheckedChangeListener{
		@Override
		public void onCheckedChanged(CompoundButton buttonView,
				boolean isChecked) {
			if(isChecked){
				//Toast
				Toast.makeText(CheckBoxActivity.this, buttonView.getText()+"被选择",Toast.LENGTH_SHORT ).show();
			}else{
				Toast.makeText(CheckBoxActivity.this, buttonView.getText()+"取消选择",Toast.LENGTH_SHORT ).show();
			}
		}
    }
    
    class ButtonClickListener implements OnClickListener{
    	String buffer = "";
		public void onClick(View v) {
			if(c1.isChecked())
				buffer = buffer+c1.getText();
			if(c2.isChecked())
				buffer = buffer +c2.getText();
			Toast.makeText(CheckBoxActivity.this, buffer+"被选择", Toast.LENGTH_SHORT).show();
		}
    }

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
    
<CheckBox android:text="金钱" android:id="@+id/CheckBox01" android:layout_width="wrap_content" android:layout_height="wrap_content"></CheckBox>
<CheckBox android:text="地位" android:id="@+id/CheckBox02" android:layout_width="wrap_content" android:layout_height="wrap_content"></CheckBox>
<Button android:id="@+id/Button01" android:text="确定" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>
