50 /LinearLayout 布局很简单一个FrameLayout用于存放不同界面的布局3个RadioButton表示下面的每一项Tab按钮。 在MainActivity中代码如下 AILayout(R.layout.main)
public class MainActivity extends AIActivity {public static final String TAG MainActivity.class.getSimpleName();AIView(R.id.main_content_view)ViewGroup contentView;AIView(R.id.main_tabs_rg)RadioGroup rg;SubLayoutManager sbManager;Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);sbManager new SubLayoutManagerSubLayout(context, contentView, TabASubLayout.class, TabBSubLayout.class, TabCSubLayout.class);sbManager.setSwitchListener(new SubLayoutManager.LayoutSwitchListenerSubLayout() {Overridepublic void switchSelf(SubLayout subLayout, int position) {Logger.d(TAG, [switch listener]switchSelf, subLayout: subLayout , position: position);}Overridepublic void switchCompleted(SubLayout subLayout, int position) {Logger.d(TAG, [switch listener]switchCompleted, subLayout: subLayout , position: position);}});rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {Overridepublic void onCheckedChanged(RadioGroup radioGroup, int i) {int index -1;switch(i){case R.id.main_tab_a_rb:index 0;break;case R.id.main_tab_b_rb:index 1;break;case R.id.main_tab_c_rb:index 2;break;}if(index 0 || index sbManager.getSubLayoutSize()){return;}sbManager.switchLayout(index);}});sbManager.switchLayout(0); // 默认切换第一页
}Overrideprotected void onDestroy() {super.onDestroy();sbManager.destoryClear();sbManager null;}} 上面的SubLayout相当于一个FragmentSubLayoutManager用于管理多个SubLayout之间的切换。SubLayoutManager可以通过new获取。 其中构造方法中 public SubLayoutManager(Context context, ViewGroup contentView, Class? extends T... slszzs) { 参数二contentView表示在MainActivity中预留给SubLayout显示的FrameLayout。 参数三是个可变长参数可以在后面有序追加所有需要切换的SubLayout的Class对象。 第一次初始化后各个SubLayout对象不会马上生成只会在切换到改页面时才会生成该对象会执行SubLayout的initLayout()方法这个方法只会调用一次类似onCreate()方法 需要切换页面时只需要执行SubLayoutManager的switchLayout()方法传入SubLayout的position就可以了这个position跟参数三的顺序一致。 接下来看下几个SubLayout是怎么去实现的因为三个SubLayout大致相同所以只分析一个就可以了 TabASubLayout代码如下 1 AILayout(R.layout.tab_a)2 public class TabASubLayout extends AISubLayout {3 public static final String TAG TabASubLayout.class.getSimpleName();4 5 6 // AIView(R.id.tab_a_tv)7 // TextView tv;8 AIView(R.id.tab_a_et)9 EditText et;
10
11 public TabASubLayout(Context context) {
12 super(context);
13 // setContentView(R.layout.tab_a);
14
15 }
16
17 Override
18 public void initLayout() {
19 super.initLayout();
20 Logger.d(TAG, initLayout...);
21 }
22
23 AIClick({R.id.tab_a_tv})
24 public void onClickCallbackSample(View view) {
25 Toast.makeText(context, clicked: ((TextView)view).getText() , et.getText(), Toast.LENGTH_SHORT).show();
26 }
27
28 Override
29 public void onResume() {
30 super.onResume();
31 Logger.d(TAG, onResume...);
32 }
33
34 Override
35 public void onPause() {
36 super.onPause();
37 Logger.d(TAG, onPause...);
38 }

40 } 代码很简单继承AISubLayout即可AISubLayout是AndroidInject中AndroidBucket的子类实现了SubLayout的注解的支持。当然你也可以直接继承SubLayout这样的话就不能使用注解了看上面的被注释的代码可以通过setContentView来设置对应的布局可以通过findViewById来获取控件对象。 它也有onResume和onPause方法当前页A被切换到B的话会调用A的onPause然后调用B的onResume如果之前B没有被初始化过则先调用initLayout再调用onResume方法 下面来看看log打印的日志 // 以下为启动应用默认加载TabA 05-05 08:22:32.216 1086-1086/com.wangjie.sublayouttest
