Question

我正试图在Android Studio项目中隐藏软键盘。 hideKeyboard（）方法中的视图不断出现为空...我无法弄清楚为什么......请指教。

  @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_rewashlog_options);

    luxuryCountTextView = (TextView) findViewById(R.id.luxuryCountTextView);
    fullCountTextView = (TextView) findViewById(R.id.fullCountTextView);
    quickCountTextView = (TextView) findViewById(R.id.quickCountTextView);
    totalCountTextView = (TextView) findViewById(R.id.totalCountTextView);
    emailRecipient = (EditText) findViewById(R.id.emailRecipient);

    instantiateMonthSpinner();
    instantiateYearSpinner();
    getEntireRewashList();
    updateListView();
    hideKeyboard();

}

 private void hideKeyboard() {
    View view = this.getCurrentFocus();
    if (view != null) {
        InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }

}

Answer 1

您可以在主要节日中使用android:windowSoftInputMode="stateHidden"隐藏活动启动时的键盘

`<activity android:name=".YourActivity"
        android:windowSoftInputMode="stateHidden" />`

Answer 2

更新InputMethodManager：

InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

Answer 3

尝试：

imm.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

就我而言，它有效。
