我有一个带标签的ViewPager + ActionBar。当我“滑动”到另一个标签时,我想隐藏软键盘,但我无法弄清楚如何。
我已经将我的Activity传递给了FragmentPageAdapter的构造函数,所以我可以调用
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
但它没有做任何事情(而且它在代码的可到达区域内)......帮助?

在您的活动中,您可以执行以下操作:
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) {
}
});

我不使用onPageSelected()
,因为隐藏键盘动画会带有滑动动画。而是使用onPageScrollStateChanged()
:
@Override
public void onPageScrollStateChanged(int state)
{
if (state == ViewPager.SCROLL_STATE_IDLE)
{
if (mViewPager.getCurrentItem() == 0)
{
// Hide the keyboard.
((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(mViewPager.getWindowToken(), 0);
}
}
}

常用方式:
private void hideVirturalKeyboard(){
View v = getCurrentFocus();
if (v != null && v instanceof EditText) {
InputMethodManager mgr = (InputMethodManager)(v.getContext().getSystemService(Context.INPUT_METHOD_SERVIC
E));
mgr.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
}

简单方法:
InputMethodManager imm = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

在我的情况下片段活动以下工作正常。
((CommentActivity)getActivity()).pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
final InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(txtComment.getWindowToken(), 0);
}
@Override
public void onPageScrolled(int position, float offset, int offsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
<强>更新强> 这是我的片段活动,其中两个片段(CommentFragment,AnotherFragment)在ViewPager中打开
public class CommentActivity extends FragmentActivity {
ViewPager pager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pager = (ViewPager) findViewById(R.id.viewPager);
.......
.......
}
private class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return CommentFragment.newInstance();
default: return AnotherFragment.newInstance();
}
}
@Override
public int getCount() {
return 2;
}
}
}
如果在CommentFragment中为EditText显示小键盘,并且想要切换到AnotherFragment并希望在切换时隐藏小键盘
public class CommentFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
.........
.........
.........
((CommentActivity)getActivity()).pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
final InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(txtComment.getWindowToken(), 0);
}
@Override
public void onPageScrolled(int position, float offset, int offsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
