如何将 BaseActivity 移植到 AppCompatActivity Android

Question

我想将 AppcompatActivity 移植到 BaseActivity。

我试图这样做，但我无法解决。 我是安卓开发新手。

可以这样做吗？否则我将不得不这样做。

但我做不到。

这是我的代码：

class MainActivity : BaseActivity() {

    private var dataFire: DataFire? = null
    private val mViewInflate: View? = null

    private val mRtcEngine: RtcEngine? = null
    private val mMuted = false

    private val TAG = VideoCallActivity::class.java.simpleName
    private var video_room_id: String? = null
    private val final_room_id: Long = 0
    private val tvUsernameVideoChat: TextView? = null
    var userIDvisited: String? = null

    private val videoFragment = VideoFragment.newInstance()

    override fun getLayoutId() = R.layout.main_activity

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        try {
            if (savedInstanceState == null) {
                getReplaceFragmentTransaction(R.id.fragmentContainer, videoFragment, VideoFragment.TAG).commit()
            }
        } catch (e: Exception) {
            Log.e("name_MainActivity", e.message.toString())
        }
    }

    override fun onBackPressed() {
        super.onBackPressed()
        //Todo: endCall()
        RtcEngine.destroy()
    }
}

提前致谢。

您必须定义基本活动

abstract class BaseActivity : Activity() {
fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(layoutResourceId)
}

protected abstract val layoutResourceId: Int

}
