试试这个

public void disableSoftKeyboard(final EditText v) {
    if (Build.VERSION.SDK_INT >= 11) {
        v.setRawInputType(InputType.TYPE_CLASS_TEXT);
        v.setTextIsSelectable(true);
    } else {
        v.setRawInputType(InputType.TYPE_NULL);
        v.setFocusable(true);
    }
}

隐藏软键盘也很有用：

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

这可用于抑制软键盘，直到用户实际触摸editText View。

与Android 10（API 29）一起工作

val activityView = activity?.window?.decorView?.rootView
activityView?.let {
    val imm = activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
    imm?.hideSoftInputFromWindow(it.windowToken, 0)
}

private void hideSoftKeyboard() {
    View view = getView();
    if (view != null) {
        InputMethodManager inputMethodManager = (InputMethodManager) getActivity()
                .getSystemService(Activity.INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

我创建了一个布局，部分来自xml，部分来自自定义布局引擎，所有这些都在代码中处理。对我来说，唯一有效的方法是跟踪键盘是否打开，并使用如下键盘切换方法：

public class MyActivity extends Activity
{
    /** This maintains true if the keyboard is open. Otherwise, it is false. */
    private boolean isKeyboardOpen = false;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        LayoutInflater inflater;
        inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(context.getResources().getIdentifier("main", "layout", getPackageName()), null);

        setContentView(contentView);
        contentView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() 
        {
            public void onGlobalLayout() 
            {
                Rect r = new Rect();
                contentView.getWindowVisibleDisplayFrame(r);
                int heightDiff = contentView.getRootView().getHeight() - (r.bottom - r.top);
                if (heightDiff > 100) 
                    isKeyboardVisible = true;
                else
                    isKeyboardVisible = false;
             });
         }
    }

    public void closeKeyboardIfOpen()
    {
        InputMethodManager imm;
        imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if (isKeyboardVisible)
            imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
    }   
}

如果要使用Java代码隐藏键盘，请使用以下命令：

  InputMethodManager imm = (InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(fEmail.getWindowToken(), 0);

或者，如果您希望始终隐藏键盘，请在AndroidManifest中使用此选项：

 <activity
 android:name=".activities.MyActivity"
 android:configChanges="keyboardHidden"  />
