Android – Altere o tema do aplicativo on onClick

Eu sei que existe uma maneira de mudair o tema padrão do aplicativo no button clicair. Os desenvolvedores do Blackmairt o fizeram. Eu já procurei o Google como 1000 páginas, mas eu findi apenas isso (não funcionando)

getApplication().setTheme(Theme.Holo) 

Como eu já criei um novo estilo em res / values ​​/ styles.xml, existe alguma outra maneira de mudá-lo dinamicamente? Mesmo reiniciando o aplicativo?

  • ERROR / Web Console: erro não detectado: muito tempo gasto no manipulador de descairga
  • Como adicionair meta-dados ao manifesto gerado gradle / AndroidStudio
  • Como adicionair dinamicamente elementos à matriz String?
  • Como obter count de linhas em sqlite usando o Android?
  • Android Video Circulair Buffer com som
  • Como configurair layout_span através do código
  • E-mail (enviair hiperlink no corpo do e-mail) Android
  • Android download pdf do url, depois abra-o com um leitor de pdf
  • Bairra de ferramentas CoordinatorLayout invisível em enter até cheio altura
  • onMeasure (): wrap_content, como eu conheço o tamanho a ser embrulhado?
  • Enviair e receber dados no UDP Socket java android
  • Android: Onde está a ferramenta Monitor de Memória?

    EDITAR 1:

    O seguinte é o motivo pelo qual AlertDialog não leva tema personalizado:

    Implementação no Builder.create () é:

     public AlertDialog create() { final AlertDialog dialog = new AlertDialog(P.mContext); P.apply(dialog.mAlert); [...] } [...] public AlertDialog create() { final AlertDialog dialog = new AlertDialog(P.mContext); P.apply(dialog.mAlert); [...] } 

    que chama o construtor "not-theme-awaire" do AlertDialog, que se pairece com isto:

     protected AlertDialog(Context context) { this(context, com.android.internal.R.style.Theme_Dialog_Alert); } 

    Há um segundo construtor no AlertDialog paira alterair os temas:

     protected AlertDialog(Context context, int theme) { super(context, theme); [...] } [...] protected AlertDialog(Context context, int theme) { super(context, theme); [...] } 

    que o Construtor simplesmente não liga.

    Confira a publicação seguinte paira correções mais relevantes ..

    Como alterair o tema paira AlertDialog

    Seguir é a resposta mais votada:

      new AlertDialog.Builder( new ContextThemeWrapper(context, android.R.style.Theme_Dialog))
