comment masquer softkeyboard dans android

Question

J'utilise le champ Modifier le texte dans mon application. quand je clique dessus, le clavier virtuel apparaît. mais quand je clique sur le bouton "DONE" (qui est sur le clavier), il devrait disparaître mais il ne disparaît pas.j'ai défini le type d'entrée comme texte dans le fichier de disposition. Je veux cacher le clavier quand j'appuie sur le bouton. s'il vous plaît aider.Merci à l'avance.

Voici mon code.

Answer 1

J'utilise cette fonction:

public static void hideSoftInput(Context ctx) 
{ 
    InputMethodManager inputManager = (InputMethodManager) ctx.getSystemService(INPUT_METHOD_SERVICE); 
    inputManager.hideSoftInputFromWindow(new View(ctx).getWindowToken(), 0); 
} 

---

Pour votre cas particulier, vous pouvez utiliser ceci:

location_entered.setOnKeyListener(new View.OnKeyListener() 
    { 
     @Override 
     public boolean onKey(View v, int keyCode, KeyEvent event) 
     { 
      if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER) 
      { 
       // code to hide the soft keyboard 
       InputMethodManager imm = (InputMethodManager) getSystemService(
        Context.INPUT_METHOD_SERVICE); 
       imm.hideSoftInputFromWindow(v.getApplicationWindowToken(), 0); 
      } 
      return false; 
     } 
    }); 

après cette partie de votre onCreate:

location_entered.setOnClickListener(new View.OnClickListener() { 
    [...] 

Answer 2

façon facile de le faire ...

 getWindow().setSoftInputMode(
     WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
