In this project, we try to implement Fragment lazy loading in two difference way. 3 | 4 | The first way is using Inheritance. We use `InheritedFakeFragment` as base Fragment and the lazy load Fragment should override `onLazyCreateView` and `onLazyViewCreated` to replace `onCreateView` and `onViewCreated`. The lazy method will be called after base Fragment got user focus. 5 | 6 | The second way is using Proxy. We create a proxy fragment `ProxyFakeFragment` and use it as a proxy to create the real Fragment. 7 | 8 | ## Using `InheritedFakeFragment` example: 9 | 10 | We need to change to `OriginFragment` to `InheritedLazyFragment` by changing `onCreateView` and `onViewCreated`. 11 | 12 | ```java 13 | public class InheritedLazyFragment extends InheritedFakeFragment { 14 | @Override 15 | public View onLazyCreateView(LayoutInflater inflater, ViewGroup container, 16 | Bundle savedInstanceState) { 17 | // Inflate the layout for this fragment 18 | View view = inflater.inflate(R.layout.fragment_origin, container, false); 19 | TextView content = (TextView) view.findViewById(R.id.FragmentContent); 20 | content.setText(mFragmentMsg + mPos); 21 | Log.d("FragmentTest" + mPos, "Pos: " + mPos + " , " + "onLazyCreateView"); 22 | return view; 23 | } 24 | 25 | @Override 26 | public void onLazyViewCreated(View view, @Nullable Bundle savedInstanceState) { 27 | super.onViewCreated(view, savedInstanceState); 28 | Log.d("FragmentTest" + mPos, "Pos: " + mPos + " , " + "onLazyViewCreated"); 29 | } 30 | } 31 | ``` 32 | Fragment creation is the same as `OriginFragment` : `return InheritedLazyFragment.newInstance("InheritedLazyFragment", position);`. 33 | 34 | ## Using `ProxyFakeFragment` example: 35 | 36 | The `OriginFragment` don't need to change and the creation process need to use proxy as : 37 | ```java 38 | Bundle bundle = new Bundle(); 39 | bundle.putString(InheritedLazyFragment.FRAGMENT_MSG, "ProxyLazyFragment"); 40 | bundle.putInt(InheritedLazyFragment.FRAGMENT_POS, position); 41 | return ProxyFakeFragment.newInstance(OriginFragment.class.getName(), bundle); 42 | ``` 43 | 44 | 中文教程请参考：[如何优化Androd App启动速度](http://www.jianshu.com/p/bef74a4b6d5e) -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @if "%DEBUG%" == "" @echo off 2 | @rem ########################################################################## 3 | @rem 4 | @rem Gradle startup script for Windows 5 | @rem 6 | @rem ########################################################################## 7 | 8 | @rem Set local scope for the variables with windows NT shell 9 | if "%OS%"=="Windows_NT" setlocal 10 | 11 | @rem Add default JVM options here.
