在外部单击时在 Fragment 中隐藏 Android 软键盘

Hide Android soft keyboard in Fragment when clicked on outside(在外部单击时在 Fragment 中隐藏 Android 软键盘)

问题描述

我有一个包含用于输入的 EditText 的片段，但现在我想在用户单击 EditText 之外的屏幕时关闭键盘.

I have a fragment containing an EditText for input, but now I want to close the keyboard when the user clicks on the screen outside of the EditText.

我知道如何在活动中执行此操作，但对于片段来说似乎有所不同.

I know how to do this in an activity, but it seems to be different for fragments.

我在 view.onTouchListener 上调用这个方法

i am calling this method on view.onTouchListener

public static void hideSoftKeyboard() {
InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);

inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
}

谁有解决办法，谢谢

推荐答案

在fragment的父Activity中重写如下方法:

In the parent Activity of the fragment override the following method:

 @Override
public boolean dispatchTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        View v = getCurrentFocus();
        if ( v instanceof EditText) {
            Rect outRect = new Rect();
            v.getGlobalVisibleRect(outRect);
            if (!outRect.contains((int)event.getRawX(), (int)event.getRawY())) {
                v.clearFocus();
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
            }
        }
    }
    return super.dispatchTouchEvent(event);
}

并且在片段的布局中使用这个属性:

And in the layout of the fragment use this attribute:

android:focusableInTouchMode="true"

希望这会对你有所帮助.
