Question

因此，当我点击非EditText视图时，我发现这段非常酷的代码可以解除键盘。除了使用getChildFragmentManager()开始的Fragments和DialogFragments之外，它的效果非常好。有人请说明为什么例外以及我如何解决它？

public static void setupUI(View view, final Activity activity) {

    // Set up touch listener for non-text box views to hide keyboard.
    if (!(view instanceof EditText)) {

        view.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                LayoutUtils.hideSoftKeyboard(activity);
                return false;
            }

        });
    }

    // If a layout container, iterate over children and seed recursion.
    if (view instanceof ViewGroup) {

        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {

            View innerView = ((ViewGroup) view).getChildAt(i);

            setupUI(innerView, activity);
        }
    }
}

private static void hideSoftKeyboard(Activity activity) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity
        .getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}

我将代码保存在实用程序类中，并在整个应用程序中使用它。基本上，对于问题情况，我在FragmentB上使用它是由FragmentA使用getChildFragmentManager()启动的，然后代码不会影响FragmentB的视图。

尝试隐藏键盘，

public void hideSoftKeyboard() {
        try {
            InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

Answer 2

尝试以下代码：

@Override
public boolean onTouchEvent(MotionEvent event) {
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
    return true;
}

Answer 3

如果您正在使用片段，请使用FragmentActivity而不是Activity。我建议使用try catch。

喜欢

try{
InputMethodManager inputMethodManager = (InputMethodManager) activity
        .getSystemService(Activity.INPUT_METHOD_SERVICE);
}catch(Exception){
InputMethodManager inputMethodManager = (InputMethodManager) fragmentactivity.getSystemService(Activity.INPUT_METHOD_SERVICE);
}

我找到了解决方案。也许其他人会发现它很有用

public static void setupUI(View view, final Activity activity) {

    // Set up touch listener for non-text box views to hide keyboard.
    if (!(view instanceof EditText)) {

        view.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                LayoutUtils.hideSoftKeyboard(activity,v);
                return false;
            }

        });
    }

    // If a layout container, iterate over children and seed recursion.
    if (view instanceof ViewGroup) {

        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {

            View innerView = ((ViewGroup) view).getChildAt(i);

            setupUI(innerView, activity);
        }
    }
}

private static void hideSoftKeyboard(Activity activity, View v) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity
        .getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
}

了解如何将activity.getCurrentFocus()替换为v。就是这样。它现在适用于所有情况。
