I am new to android, and I would like to implement a tab layout and a viewpager infragments,showing a pop up window, such that when I click a button the pop up window could cover the keyboard and I could view the tab layout within. If it's possible, then is there any example I could refer to?
EDIT: Let me rephrase, What I wanted to ask was how can I put the tab layout and view pager in the pop up window.
这是处理弹出窗口
创建的PopupViewHandler类public class PopupViewHandler {
AppCompatActivity mActivity;
PopupWindow window;
Context mContext;
LayoutInflater layoutInflater;
View popupView;
PopupViewHandler(AppCompatActivity mActivity, Context mContext) {
this.mActivity = mActivity;
this.mContext = mContext;
}
public void setupstuff() {
layoutInflater = (LayoutInflater) mActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
popupView = layoutInflater.inflate(R.layout.tab_layout, (ViewGroup) mActivity.findViewById(R.id.main_layout));
TabLayout tabLayout = (TabLayout) popupView.findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) popupView.findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(mActivity.getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
window = new PopupWindow(
popupView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
window.showAtLocation(popupView, Gravity.CENTER, 0, 0);
}
}
这是tab_layout xml。
<LinearLayout
android:id="@+id/main_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
这就是我通过主要活动按钮点击启动此课程的方法 -
handler = new PopupViewHandler(MainActivity.this, getBaseContext());
handler.setupstuff();
但是当我运行它并单击按钮时，我收到以下错误：

答案 0 :(得分：0)
您可以使用 InputMethodManager 隐藏虚拟键盘，调用hideSoftInputFromWindow，传入包含您视图的窗口的标记。
View view = this.getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
您需要使用上下文来启动InputMethodManager，然后您可以将此代码用于所需的视图。
