Android 已经过时的方法用什么新方法替代?

过时修正举例 (Kotlin):

getColor():

    resources.getColor(R.color.white) //已过时
    
    // 修正后:
    ContextCompat.getColor(this, R.color.white)

 getDrawable():

    resources.getDrawable(R.mipmap.test)    //已过时
    
    //修正后:
    ContextCompat.getDrawable(this, R.mipmap.test)    //this = Context

setCompoundDrawables():        //未过时但不建议使用

    view?.setCompoundDrawables(null,null,null,null)  //未过时但不建议使用
    
    //修正后:
    view?.setCompoundDrawablesWithIntrinsicBounds(null, null, null, null)

BluetoothAdapter.getDefaultAdapter().isEnabled:        //获取蓝牙开关状态

    if (!BluetoothAdapter.getDefaultAdapter().isEnabled) {    //已过时
        //打开蓝牙开关
        activity?.startActivity(Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE))
    }
    
    //修正后:
    if (!((activity?.getSystemService(Context.BLUETOOTH_SERVICE) as 
        BluetoothManager).adapter.isEnabled)) {
         //打开蓝牙开关
         activity?.startActivity(Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE))
     }

requestWindowFeature(Window.FEATURE_NO_TITLE):        //去除Activity默认头部

    //当Activity继承FragmentActivity时使用:
    requestWindowFeature(Window.FEATURE_NO_TITLE)     
          
    //当Activity继承AppCompatActivity时使用:
    supportRequestWindowFeature(Window.FEATURE_NO_TITLE)
