当登录活动加载了已经填充了sharedPreferences数据的EditText时，我试图隐藏软件键盘。
我已经在其他问题中尝试了这段代码，但它不起作用:
if(inputEmail.getText().toString().trim() != null){
InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(inputEmail.getWindowToken(),0);
}
<LinearLayout

我使用InputMethodManager只在这种情况下，当我试图隐藏键盘，请帮助!

您应该将隐藏键盘代码替换为以下行:
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
现在有帮助了。
欢呼
隐藏软键盘尝试使用:
/**
* Hides Soft Keyboard displayed by currently focused EditText
*
* @param pEditText EditText currenly focused EditText
*/
protected void hideSoftKeyboard( EditText pEditText )
{
InputMethodManager lInputMethodManager = (InputMethodManager) pEditText.getContext().getSystemService( Context.INPUT_METHOD_SERVICE );
lInputMethodManager.hideSoftInputFromWindow( pEditText.getWindowToken() , 0 );
}
检查trim()的result是否为空字符串，而不是null
使用android:windowSoftInputMode="stateHidden"来隐藏键盘
