android在按下回车键时设置隐藏键盘(在EditText中)

Question

当我的用户在虚拟 android 上按 Enter 时“用户验证条目!”键盘 我的键盘保持可见! (为什么？)

这是我的 Java 代码...

private void initTextField() {
    entryUser = (EditText) findViewById(R.id.studentEntrySalary);
    entryUser.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (event.getAction() == KeyEvent.ACTION_DOWN) {
                switch (keyCode) {
                    case KeyEvent.KEYCODE_DPAD_CENTER:
                    case KeyEvent.KEYCODE_ENTER:
                        userValidateEntry();
                        return true;
                }
            }

          return true;
        }
    });
}

private void userValidateEntry() {
    System.out.println("user validate entry!");
}

...这里是我的观点

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">
            <EditText android:id="@+id/studentEntrySalary" android:text="Foo" android:layout_width="wrap_content" android:layout_height="wrap_content" />
 </LinearLayout>

我的虚拟设备可能有问题？

应该这样做:

yourEditTextHere.setOnEditorActionListener(new OnEditorActionListener() {

        @Override
        public boolean onEditorAction(TextView v, int actionId,
                KeyEvent event) {
            if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
                InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

                // NOTE: In the author's example, he uses an identifier
                // called searchBar. If setting this code on your EditText
                // then use v.getWindowToken() as a reference to your 
                // EditText is passed into this callback as a TextView

                in.hideSoftInputFromWindow(searchBar
                        .getApplicationWindowToken(),
                        InputMethodManager.HIDE_NOT_ALWAYS);
               userValidateEntry();
               // Must return true here to consume event
               return true;

            }
            return false;
        }
    });
