横竖屏切换适配总结

开发测试环境Android 7.0

一.配置测试

1.不配置任何东西

切换横竖屏调用了

2.配置只orientation

android:configChanges="orientation"

切换横竖屏调用了

3.配置orientation|keyboardHidden

android:configChanges="orientation|keyboardHidden"
android:launchMode="singleTask"
android:windowSoftInputMode="stateHidden|adjustResize" 

以上切换横竖屏 Activty 调用了

1. onConfigurationChanged:
2. onSaveInstanceState:
3. onDestroy:
4. onCreat
5. onRestoreInstanceState

---

4.配置orientation|screenSize|keyboardHidden

android:configChanges="orientation|screenSize|keyboardHidden"
android:launchMode="singleTask"
android:windowSoftInputMode="stateHidden|adjustResize"

切换横竖屏 Activty 调用了

1. onConfigurationChanged:

其他均没调用

---

5.Fragment 设置setRetainInstance(true)后

切换横竖屏 Fragment 调用了

1. onSaveInstanceState
2. onDestroyView:
3. onCreateView:
4. onViewCreated:
5. onActivityCreated:
6. onRestoreInstanceState:

没有调用onCreat 和 onDeatory onConfigurechanged

二.适配

1. 重启Activity (manifest中1-3配置)

创建两个layout文件夹layout layout-land
activity会自动加载横竖屏layout，另外你可根据方向设置Gridlayout spancount等来适配。

在onCreat中恢复fragment，onSaveInstanceState保存fragment

---

把需要保持的fragment设置setRetainInstance(true)，同样由于fragment会调用 onViewCreated: onActivityCreated: 也可加载不同方向layout

 if (bundle != null) {
            FragmentManager supportFragmentManager = getSupportFragmentManager();
            sickbedF = (SickbedF) supportFragmentManager.getFragment(bundle, "sickbedF");
            communicateF = (CommunicateF) supportFragmentManager.getFragment(bundle, "communicateF");
            hospitalF = (HospitalF) supportFragmentManager.getFragment(bundle, "hospitalF");
            mineF = (MineF) supportFragmentManager.getFragment(bundle, "mineF");
        }
        
         @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt("checkedID", checkedID);
        getSupportFragmentManager().putFragment(outState, "sickbedF", sickbedF);
        getSupportFragmentManager().putFragment(outState, "hospitalF", hospitalF);
        getSupportFragmentManager().putFragment(outState, "communicateF", communicateF);
        getSupportFragmentManager().putFragment(outState, "mineF", mineF);
        if (Constance.DEBUGTAG)
            Log.i(Constance.DEBUG + "--" + getClass().getSimpleName() + "--", "onSaveInstanceState: ");
    }

---

2.不重启Activity

配置orientation|screenSize|keyboardHidden

重写 onconfigureChanged 根据不同方向调整不同布局，以recyclerview为例，可以定义不同方向布局创建不同Viewholder，方向改变时调用adapter.notifyDateChanged

如下图根据不同方向返回不同布局类型例子

 .addType(R.layout.doctor_info, new SBaseMutilAdapter.ITEMHOLDER<DoctorInfo>() {
    @Override
     public boolean istype(DoctorInfo item, int position) {
      return position == 0 && OrentionUtils.isPortrait(DoctorHome.this);}})
.addType(R.layout.doctor_info_land, new SBaseMutilAdapter.ITEMHOLDER<DoctorInfo>() {
    @Override
    public boolean istype(DoctorInfo item, int position) {
    return position == 0 && !OrentionUtils.isPortrait(DoctorHome.this);}})
