鍵盤沒有顯示出來，但使用和點擊<code>EditText</code>鍵盤後發達的EditText

Question

我想在我的項目中使用this有用的庫點擊時沒有顯示出來，這個簡單的類作爲庫部署EditText

public class AlachiqMakeLink extends EditText { 

    private static final String TAG = AlachiqMakeLink.class.getSimpleName();

您可以強制顯示或通過添加切換

InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE); 
    if (imm.isActive()){ 
     imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); // hide 
    } else { 
     imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY); // show 
    }
