Listview 列表视图未在片段中滚动

我创造了这个抽屉。选择一个项目时，它将显示一个带有列表视图的片段。该列表视图没有滚动

代码如下：

主要活动

private NavigationDrawerFragment mNavigationDrawerFragment;
private CharSequence mTitle;
FrameLayout frameLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     frameLayout = (FrameLayout)findViewById(R.id.container);

    mNavigationDrawerFragment = (NavigationDrawerFragment)
            getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
    mTitle = getTitle();

    mNavigationDrawerFragment.setUp(
            R.id.navigation_drawer,
            (DrawerLayout) findViewById(R.id.drawer_layout));
}

@Override
public void onNavigationDrawerItemSelected(int position) {
    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    switch (position) {
        case 1:
            break;
        case 2:

            Fragment f = new ChordFragment();

            fragmentTransaction.replace(R.id.container, f).commit();
            break;
        case 3:
            break;
        case 4:
            break;
    }

}

public void onSectionAttached(int number) {
    switch (number) {
        case 1:
            mTitle = getString(R.string.navi_home);
            break;
        case 2:
            mTitle = getString(R.string.navi_favourite);
            break;
        case 3:
            mTitle = getString(R.string.navi_new);
            break;
        case 4:
            mTitle = getString(R.string.navi_rateus);
            break;
    }
}

public void restoreActionBar() {
    ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
    actionBar.setDisplayShowTitleEnabled(true);
    actionBar.setTitle(mTitle);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    if (!mNavigationDrawerFragment.isDrawerOpen()) {
        // Only show items in the action bar relevant to this screen
        // if the drawer is not showing. Otherwise, let the drawer
        // decide what to show in the action bar.
        getMenuInflater().inflate(R.menu.main, menu);
        restoreActionBar();
        return true;
    }
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

CHORDFRAGMENT

public class ChordFragment extends Fragment {

ListView mChordList;
ArrayList<TCDataModel> list = new ArrayList<TCDataModel>();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    /** Inflating the layout for this fragment **/
    View v = inflater.inflate(R.layout.fragment_chord, null);

    mChordList = (ListView) v.findViewById(R.id.lv_chords);
    for (int i = 0; i < 20; i++) {
        TCDataModel mTCDataModel = new TCDataModel();
        mTCDataModel.setSongName("Song Name " + i);
        mTCDataModel.setMuviName("Muvi Name " + i);
        list.add(mTCDataModel);
    }
    mChordList.setAdapter(new ChordListAdapter(getContext(), list));
    return v;
}

公共类ChordFragment扩展了片段{
ListView-mChordList；
ArrayList=新建ArrayList（）；
@凌驾
CreateView上的公共视图（布局、充气机、视图组容器、捆绑包保存状态）{
/**正在为该片段扩展布局**/
视图v=充气机。充气（R.layout.fragment_chord，空）；
mChordList=（列表视图）v.findViewById（R.id.lv_和弦）；
对于（int i=0；i<20；i++）{
TCDataModel mTCDataModel=新的TCDataModel（）；
mTCDataModel.setSongName（“歌曲名”+i）；
mTCDataModel.setMuviName（“Muvi名称”+i）；
list.add（mTCDataModel）；
}
setAdapter（新的ChordListAdapter（getContext（），list））；
返回v；
}

}

如果您按如下方式修改主\u activity.xml文件，则它工作正常：

 <android.support.v4.widget.DrawerLayout     xmlns:android="http://schemas.android.com/apk/res/android"

如果您已经解释了OP代码的错误以及您所更改的内容，这将非常有用。现在，读者必须上下上下查看，试图了解差异是什么，并尝试猜测这些更改是否与类似但不完全相同的问题相关。如果您已经解释了OP代码的错误以及您所更改的内容，这将非常有帮助。现在，读者必须上下、上下查看，以了解差异是什么，并尝试猜测这些变化是否与类似但不完全相同的问题相关。
