15         android:id="@+id/cb_2"
16         android:checked="true"/>
17     <CheckBox

19         android:layout_height="wrap_content"
20         android:text="彭丽媛"
21         android:id="@+id/cb_3"
22         android:checked="true"/>
23     </LinearLayout>

2.开关按钮的添加

 1 <LinearLayout
 2         android:layout_width="wrap_content"
 3         android:layout_height="wrap_content">

 5         android:layout_width="wrap_content"
 6         android:layout_height="wrap_content"
 7         android:textOn="开"

3.对于复选框的提示监视器的添加

 1 CheckBox cb_1;
 2 CheckBox cb_2;
 3 CheckBox cb_3;
 4
 5 protected void onCreate(Bundle savedInstanceState) {
 6 super.onCreate(savedInstanceState);
 7 setContentView(R.layout.activity_test1);
 8
 9 cb_1 = (CheckBox)findViewById(R.id.cb_1);
10 cb_2 = (CheckBox)findViewById(R.id.cb_2);
11 cb_3 = (CheckBox)findViewById(R.id.cb_3);
12
13 //监听器的实例
14 CB_oncheckedchangelistener cb1 = new CB_oncheckedchangelistener();
15 //监听器绑定
16 cb_1.setOnCheckedChangeListener(cb1);
17 cb_2.setOnCheckedChangeListener(cb1);
18 cb_3.setOnCheckedChangeListener(cb1);
19
20 class CB_oncheckedchangelistener implements CompoundButton.OnCheckedChangeListener
21     {
22         @Override
23         public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
24
25             CheckBox cb = (CheckBox)buttonView;
26
27             String str = cb.getText().toString();
28
29             if (isChecked)
30             {
31                 Toast.makeText(TestActivity1.this, str+"被选中", Toast.LENGTH_SHORT).show();
32             }
33             else
34             {
35                 Toast.makeText(TestActivity1.this,str+"被取消选中", Toast.LENGTH_SHORT).show();
36             }
37         }
38     }

4.对于开关按钮的提示监视器的添加

 1 tb_1 = (ToggleButton)findViewById(R.id.tb_1);
 2
 3 sw_1 = (Switch)findViewById(R.id.sw_1);
 4
 5 tb_1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
 6             @Override
 7             public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
 8                 Toast.makeText(TestActivity1.this,"开关状态 = "+(isChecked?"开":"关"), Toast.LENGTH_SHORT).show();
 9
10             }
11         });
12
13 sw_1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
14             @Override
15             public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
16                 Toast.makeText(TestActivity1.this, "开关状态= "+(isChecked?"开":"关"), Toast.LENGTH_SHORT).show();
17             }
18         });
