在TabLayout

Question

我正在使用一个简单的TabLayout在我的应用程序中显示由RecyclerViewAdapter构成的三个不同列表，如下所示：

问题在于，每次加载此活动或更改选项卡时，键盘都会自动显示。

以下是我的不同文件：

MainActivity.java

private DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

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

    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    final ActionBar ab = getSupportActionBar();
    if (ab != null) {
        ab.setHomeAsUpIndicator(R.drawable.ic_menu);
        ab.setDisplayHomeAsUpEnabled(true);
    }

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    if (navigationView != null) {
        setupDrawerContent(navigationView);
    }

    ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
    if (viewPager != null) {
        setupViewPager(viewPager);
    }

    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    if (tabLayout != null){
        tabLayout.setupWithViewPager(viewPager);
    }

    //Initializing NavigationView
    navigationView = (NavigationView) findViewById(R.id.nav_view);

    //Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
    if (navigationView != null) {
        navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

            // This method will trigger on item Click of navigation menu
            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {

            //Checking if the item is in checked state or not, if not make it in checked state
            if (menuItem.isChecked()) menuItem.setChecked(false);
            else menuItem.setChecked(true);

            //Closing drawer on item click
            mDrawerLayout.closeDrawers();

            switch (menuItem.getItemId()) {
                // Drawer options
            }
        });
    }
}


/*
@Override
public boolean onCreateOptionsMenu(Menu item) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.options_menu, item);

    SearchManager searchManager =
            (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView =
            (SearchView) item.findItem(R.id.action_search).getActionView();
    searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));
    return true;
}*/


@Override
public boolean onCreateOptionsMenu(final Menu menu) {
    getMenuInflater().inflate(R.menu.options_menu, menu);

    final MenuItem searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (android.widget.SearchView) searchItem.getActionView();

    final MenuItem filterItem = menu.findItem(R.id.action_filter);

    searchView.setQueryHint(getString(R.string.search_hint));
    searchView.setIconified(false);

                    return true;
                }
            });
}

static class Adapter extends FragmentPagerAdapter {
    private final List<Fragment> mFragments = new ArrayList<>();
    private final List<String> mFragmentTitles = new ArrayList<>();

    public Adapter(FragmentManager fm) {
        super(fm);

    }

    @Override
    public CharSequence getPageTitle(int position) {

    }
}

ListFragment.java

    super.onAttach(activity);
    if (mRecyclerView == null){
        return;
    }

}


private void loadUpdates() {
    showListView(false);

    //Gets information from the server and call setAdapter()

}

private void setAdapter() {

    if ( ((MainActivity)getActivity()).getPostList() == null) {
        Log.i(MainActivity.TAG, "not ready to set Adapter");
        return;
    }

    showListView(true);

    mAdapter = new PostAdapter(((MainActivity)getActivity()).getPostList(),this.getContext());
    mRecyclerView.setAdapter(mAdapter);

我希望我没有错过任何事情，并提前感谢您的帮助。

修改：

这是我在清单中的活动，因为建议在这里改变一些东西

    <activity android:name=".MainActivity"
        android:theme="@style/Base.Theme.NoTitleBar"
        android:windowSoftInputMode="stateAlwaysHidden">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Answer 1

好的，我已经找到了导致键盘显示的内容，我有一个带有搜索按钮的菜单，但是工作得很好，原来是我的菜单造成了所有麻烦，无论如何，谢谢所有的帮助！

Answer 2

只需在清单中为发生问题的特定活动添加android：windowSoftInputMode =“stateAlwaysHidden”

Answer 3

我认为 OnTabChangeListener是执行此类操作的最佳位置。

var initialPlay = false;

$("#vid-pages").find("video").on('canplay', function() {
  if (initialPlay) return;
  initialPlay = true;

  $(this)[0].currentTime = $(this)[0].duration / 2;
  console.log($(this)[0].currentTime);
});

请同时查看this

Answer 4

将这些行放入.Xml文件

机器人：descendantFocusability =＆＃34; beforeDescendants＆＃34; 机器人：focusableInTouchMode =＆＃34;真＆＃34;

Answer 5

用这个检查

            InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            if (inputMethodManager != null)
                inputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
