How to setTheme to an activity at runtime? It doesn't work call setTheme before onCreate and setContentView

Question

I want setTheme to an activity at runtime, I have search some solutions by google. someone said call setTheme before onCreate and setContentView can works, the code section like

public void onCreate(Bundle savedInstanceState) {     setTheme(android.R.style.Theme_Translucent_NoTitleBar);     super.onCreate(savedInstanceState);     ...     setContentView(...) } 

but it not works, I want to know, is there another solution can setTheme to activity?

Answer 1

Just try this - set your theme after super.onCreate(savedInstanceState); and before setContentView(...)

Like below code -

public void onCreate(Bundle savedInstanceState)  {     super.onCreate(savedInstanceState);     setTheme(android.R.style.Theme_Translucent_NoTitleBar); // Set here     setContentView(...) } 

Answer 2

Actually this only worked for me if I set it before calling super.onCreate(savedInstanceState);

public void onCreate(Bundle savedInstanceState) {     final int themeRes = getIntent().getIntExtra(EXTRA_THEME_ID, 0);     if (themeRes != 0) setTheme(themeRes);     super.onCreate(savedInstanceState);     //ect... }
