为了更方便的使用Frgment,使用扩展方法对其进行扩展,来简化其使用方式
添加扩展函数
inline fun FragmentManager.inTransaction(func: FragmentTransaction.() -> FragmentTransaction) = beginTransaction().func().commit()fun AppCompatActivity.addFragment(fragment: Fragment, frameId: Int) = supportFragmentManager.inTransaction { add(frameId, fragment) }fun AppCompatActivity.replaceFragment(fragment: Fragment, frameId: Int) = supportFragmentManager.inTransaction{replace(frameId, fragment)}
activity中进行调用
addFragment(mFragment1, R.id.mFlContent) replaceFragment(mFragment2, R.id.mFlContent)
