Android BaseActivity抽象举例

核心内容:

log常用标记TAG赋值,

状态栏设置,

逻辑区分,

onNewIntent重写,

跳转方法简化.

状态栏原生方案（可选）

子Activity继承举例:

class LoginActivity : BaseActivity() {

    override val mContentView: Int = R.layout.activity_login

    override fun initView() {}

    override fun initData() {}

    override fun setListener() {}

}
