android - 未找到 ID 0x7f0e00d5 的 View (com.example.page :id/dialogViewpager) for fragment OneFragment{92c0220 #1 id=0x7f0e00d5 android:switcher:2131624149:0}

标签 android android-fragments dialog android-tablayout

我想在对话框中显示 tabview。 我有一个扩展到 FragmentActivity 的主类文件，在其中我通过调用此方法来显示对话框，如下所示。

private void dialogDictionary() {

    final Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog_dictionary);
    dialog.setCancelable(true);

    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

    ImageView imgDialogDictionaryClose = (ImageView) dialog.findViewById(R.id.imgDialogDictionaryClose);
    imgDialogDictionaryClose.setOnClickListener(v -> dialog.dismiss());

    ViewPager viewPager = (ViewPager) dialog.findViewById(R.id.dialogViewpager);
    setupViewPager(viewPager);

    TabLayout tabLayout = (TabLayout) dialog.findViewById(R.id.dialogTabs);
    tabLayout.setupWithViewPager(viewPager);

    dialog.show();
}

private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new OneFragment(), "ONE");
    adapter.addFragment(new TwoFragment(), "TWO");
    adapter.addFragment(new ThreeFragment(), "THREE");
    viewPager.setAdapter(adapter);
}

class ViewPagerAdapter extends FragmentPagerAdapter {

    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager) {
        super(manager);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    public void addFragment(Fragment fragment, String title) {
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }
}

当我运行应用程序时，出现此错误。

最佳答案

据我所知，我并没有立即添加对话框的内容 View 。它是在显示对话框时添加的。您可以尝试做的是创建 Dialog 的子类并将全局布局监听器添加到您的 Dialog 子类。

当 GlobalLayoutListener 触发时，此时获取您的引用，然后移除 Global Layout Listener，这样它就不会一直重新触发。

// in OnCreate()
getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener(){
    @Override
    public void onGlobalLayout() 
    {
        //get references for viewPager
        viewPager = findViewById(R.id.dialogViewpager)
        //remove listener so it doesn't fire again
        getViewTreeObserver().removeOnGlobalLayoutListener(this);
    }
});

更新:

实际上，根据我的想法，您可以创建一个普通对话框并向其添加布局监听器

//note that dialog will need to be final to access it
//in onGlobalLayout below or have a global reference in your class

dialog.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener(){
    @Override
    public void onGlobalLayout() 
    {
        //get references for viewPager
        viewPager = findViewById(R.id.dialogViewpager)
        //remove listener so it doesn't fire again
        dialog.getViewTreeObserver().removeOnGlobalLayoutListener(this);
    }
});
