在Android中输入EditText后如何隐藏键盘？

Question

我有一个EditText按钮与父母的底部对齐.

当我在其中输入文本并按下按钮以保存数据时,虚拟键盘不会消失.

任何人都可以指导我如何隐藏键盘吗？

Answer 1

您可能还想在EditText中定义imeOptions.这样,按完成后键盘就会消失:

<EditText
    android:id="@+id/editText1"
    android:inputType="text"
    android:imeOptions="actionDone"/>

Answer 2

这应该工作.

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

只要确保this.getCurrentFocus()不返回null,如果没有焦点则会返回null.

Answer 3

   mEtNumber.setOnEditorActionListener(new TextView.OnEditorActionListener() {

            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if (actionId == EditorInfo.IME_ACTION_DONE) {
                    // do something, e.g. set your TextView here via .setText()
                    InputMethodManager imm = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
                    return true;
                }
                return false;
            }
        });

并在xml中

  android:imeOptions="actionDone"

Answer 4

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

Answer 5

我没有看到任何人使用此方法：

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean focused) {
        InputMethodManager keyboard = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        if (focused)
            keyboard.showSoftInput(editText, 0);
        else
            keyboard.hideSoftInputFromWindow(editText.getWindowToken(), 0);
    }
});

然后只需将焦点集中到editText即可：

editText.requestFocus();

EditText操作侦听器中包含的解决方案：

public void onCreate(Bundle savedInstanceState) {
    ...
    ...
    edittext = (EditText) findViewById(R.id.EditText01);
    edittext.setOnEditorActionListener(new OnEditorActionListener() {
        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);
                in.hideSoftInputFromWindow(edittext.getApplicationWindowToken(),InputMethodManager.HIDE_NOT_ALWAYS);
            }
            return false;
        }
    });
    ...
    ...
}
