在Android中在EditText之外单击时关闭键盘 [英] Dismiss keyboard when click outside of EditText in android

问题描述

我有一个名为myTextview的EditText.我希望在单击EditText时显示软键盘，但是如果在EditText之外单击则关闭软键盘.所以我用下面的方法.但是，当我在视图外部单击(单击TextView)时，键盘不会关闭.如何解决此代码?

I have an EditText called myTextview. I want the soft keyboard to show when I click on the EditText but then dismiss if I click outside of the EditText. So I use the method below. But the keyboard does not dismiss when I click outside the view (I click a TextView). How do I fix this code?

myTextview.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
            } else {
                InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(myTextview.getWindowToken(), 0);
            }

        }
    });

推荐答案

我找到了更好的解决方案:

I found a better solution:

覆盖活动"中的dispatchTouchEvent方法.

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    View v = getCurrentFocus();

    if (v != null && (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) &&
            v instanceof EditText &&
            !v.getClass().getName().startsWith("android.webkit.")) {
        int[] sourceCoordinates = new int[2];
        v.getLocationOnScreen(sourceCoordinates);
        float x = ev.getRawX() + v.getLeft() - sourceCoordinates[0];
        float y = ev.getRawY() + v.getTop() - sourceCoordinates[1];

        if (x < v.getLeft() || x > v.getRight() || y < v.getTop() || y > v.getBottom()) {
            hideKeyboard(this);
        }

    }
    return super.dispatchTouchEvent(ev);
}

private void hideKeyboard(Activity activity) {
    if (activity != null && activity.getWindow() != null) {
        activity.getWindow().getDecorView();
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            imm.hideSoftInputFromWindow(activity.getWindow().getDecorView().getWindowToken(), 0);
        }
    }
}

这是适用的，即使您使用的是Webview.

This is applicable even if you are working with webview.

上述方法可以正常工作，但是EditText仍然具有焦点，并且键入光标仍然可见.

The above method works perfectly but the EditText is still has the focus and typing cursor is still visible.

解决上述问题.这样做

1. 添加 findViewById(android.R.id.content).setFocusableInTouchMode(true); 在您的onCreate()方法中

1. Add findViewById(android.R.id.content).setFocusableInTouchMode(true); in your onCreate() method

在 hideKeyboard()方法
