以编程方式隐藏软键盘在ViewPager.OnPageChangeListener onPageSelected（）？ [英] Programmatically Hide Soft Keyboard in ViewPager.OnPageChangeListener onPageSelected()?

问题描述

我有一个ViewPager +动作条与标签。我想使软键盘隐藏时，我刷到另一个选项卡，但我无法弄清楚如何。

I have a ViewPager + ActionBar with tabs. I want to make the soft keyboard hide when I "swipe" to another tab but I can't figure out how.

我已经通过我的活动来的构造FragmentPageAdapter这样我就可以叫

I've passed in my Activity to the constructor for the FragmentPageAdapter so I can call

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

不过，这并不做任何事情（和它在的code可到达区域）...帮助？

But it doesn't do anything (and it is in a reachable area of the code)...help?

推荐答案

在你的活动，你可以做到以下几点：

In your activity, you can do the following:

mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageSelected(int position) {
        final InputMethodManager imm = (InputMethodManager)getSystemService(
            Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(mView.getWindowToken(), 0);
    }

    @Override
    public void onPageScrolled(int position, float offset, int offsetPixels) {
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }
});
