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)
