将actionbarsherlock与android-support-v4一起使用（版本23） [英] Using actionbarsherlock with android-support-v4 (Version 23)

问题描述

我正在使用actionbarsherlock开发一个应用，并且ABS项目当前正在使用android-support-v4库（版本18）。现在，我想扩展我的项目以支持Android 6.0，并使用诸如

  ContextCompat.checkSelfPermission（thisActivity ，Manifest.permission.WRITE_CALENDAR）
  

或

  ActivityCompat.shouldShowRequestPermissionRationale（thisActivity，Manifest.permission.READ_CONTACTS）
  

我需要版本23的支持库。但是ABS项目与此最新库不兼容，并且出现错误，例如 mAdded无法解析或不是Watson.java中的字段

另外，请不要在尝试时建议我使用AppCompatActivity而不是ABS，但由于我的项目很大，因此会卡在其他混乱的网络中。

解决方案

我遇到了同样的问题。这是我的解决方案：

克隆 ActionBarSherlock

没有实例字段m类型为Landroid / support / v4 / app / FragmentManagerImpl的片段;

  // android.support.v4.app.FragmentActivity 
 
 // com.android.support:support-v4:22.+ 
 final FragmentManagerImpl mFragments = new FragmentManagerImpl（）; 
 
 // com.android.support:support-v4:23.+ 
 final FragmentController mFragments = FragmentController.createController（new HostCallbacks（））; 
 
 // android.support.v4.app.FragmentManager.FragmentManagerImpl 
 ArrayList< Fragment>已添加； 
  

所以我们需要获取 FragmentManagerImpl 的实例来访问 mAdded 字段

  // android.support.v4.app.FragmentActivity 
 public FragmentManager getSupportFragmentManager（）{ 
返回mFragments.getSupportFragmentManager（）; 
} 
 
 // android.support.v4.app.FragmentController 
 public FragmentManager getSupportFragmentManager（）{
 return mHost.getFragmentManagerImpl（）; 
} 
  

将以下方法添加到android.support.v4.app.Watson类

  @Nullable 
 private List< Fragment> getAddedFragments（）{
 return（（FragmentManagerImpl）getSupportFragmentManager（））。mAdded; 
} 
  

将以下代码添加到 onCreatePanelMenu 中， onPreparePanel 和 onMenuItemSelected 方法，并将 mFragments.mAdded 替换为 fragments

  List< Fragment>片段= getAddedFragments（）; 
  

FloatMath

<从历史上看，这些方法比等效的基于双精度的
{java.lang.Math}方法要快。在具有JIT的Android版本上，它们的
变慢了，并且此后被重新实现以包装对
的调用{java.lang.Math}。 {java.lang.Math}应该优先使用
。

所有方法均已从版本23的公共API中删除。

@不建议使用{java.lang.Math}。

替换所有出现的<在 com.actionbarsherlock.internal.nineoldandroids.view.animation.AnimatorProxy

$ p $ b中的带有 Math 的em> FloatMath

I'm developing an app with actionbarsherlock and the ABS project is currently using android-support-v4 library (Version 18). Now I want to extend my project to support Android 6.0 and in order to use some of the methods like

ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_CALENDAR)

or

ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, Manifest.permission.READ_CONTACTS)

I require support library version 23. But ABS project is not compatible with this latest library and gives error like mAdded cannot be resolved or is not a field in Watson.java

Also, please don't suggest me to use AppCompatActivity instead of ABS as I tried it but getting stuck in a web of other mess as my project is quite big.

解决方案

I'm facing the same problem. Here's my solution:

Clone ActionBarSherlock

No instance field mFragments of type Landroid/support/v4/app/FragmentManagerImpl;

// android.support.v4.app.FragmentActivity

// com.android.support:support-v4:22.+
final FragmentManagerImpl mFragments = new FragmentManagerImpl();

// com.android.support:support-v4:23.+
final FragmentController mFragments = FragmentController.createController(new HostCallbacks());

// android.support.v4.app.FragmentManager.FragmentManagerImpl
ArrayList<Fragment> mAdded;

So we need to get instance of FragmentManagerImpl to access mAdded field

// android.support.v4.app.FragmentActivity
public FragmentManager getSupportFragmentManager() {
    return mFragments.getSupportFragmentManager();
}

// android.support.v4.app.FragmentController
public FragmentManager getSupportFragmentManager() {
    return mHost.getFragmentManagerImpl();
}

Add the following method to the android.support.v4.app.Watson class

@Nullable
private List<Fragment> getAddedFragments() {
    return ((FragmentManagerImpl) getSupportFragmentManager()).mAdded;
}

Add the following code to onCreatePanelMenu, onPreparePanel and onMenuItemSelected methods and replace mFragments.mAdded with fragments

List<Fragment> fragments = getAddedFragments();

FloatMath

Historically these methods were faster than the equivalent double-based {java.lang.Math} methods. On versions of Android with a JIT they became slower and have since been re-implemented to wrap calls to {java.lang.Math}. {java.lang.Math} should be used in preference.

All methods were removed from the public API in version 23.

@deprecated Use {java.lang.Math} instead.

Replace all of occurrences of FloatMath with Math in com.actionbarsherlock.internal.nineoldandroids.view.animation.AnimatorProxy
