android – Spinner下拉列表在选择项目后在listview中绘制屏幕顶部

1)在视觉上可以看到问题here.

2)更改ListItem属性后

android:descendantFocusability="afterDescendants"

我的行为更好,但仍有一些事情发生.看起来列表中的项目似乎没有收到事件,因此属性更改对我来说很有意义.
Here is a video更新该属性后微调器的行为.
一切正常,除非我实际选择了一个项目.

3)设置ListView的layout_height =“match_parent”后,问题似乎在选择项目后消失. See here为该视频.

活动：

public class SELEctOractivity extends Activity {

public static final String TAG = SELEctOractivity.class.getSimplename();

@Override
protected void onCreate(Bundle savedInstanceStatE) {
    super.onCreate(savedInstanceStatE);
    Log.v(tag,"onCreate");
    setContentView(R.layout.activity_SELEctor);

    LayoutInflater inflater = (LayoutInflater) getSystemservice(Context.LAYOUT_INFLATER_serviCE);

    ListView contents = (ListView) findViewById(R.id.list_view);    
    contents.addHeaderView(new TestView(this));
    contents.addFooterView(new View(this));
    SimpleBaseAdapter listadapter = new SimpleBaseAdapter(this);

    // LOW RANGE
    LinearLayout lowRange = (LinearLayout) inflater.inflate(R.layout.list_item_edit,null);
    TextView lowRangeText = (TextView) lowRange.findViewById(R.id.text);
    EditText lowRangeEditText = (EditText) lowRange.findViewById(android.R.id.edit);
    // HIGH RANGE
    LinearLayout highRange = (LinearLayout) inflater.inflate(R.layout.list_item_edit,null);
    TextView highRangeText = (TextView) highRange.findViewById(R.id.text);
    EditText highRangeEditText = (EditText) highRange.findViewById(android.R.id.edit);
    // UNITS
    LinearLayout units = (LinearLayout) inflater.inflate(R.layout.list_item_units,null);
    TextView unitsText = (TextView) units.findViewById(android.R.id.text1);

    // SPINNERS
    LinearLayout spinners = (LinearLayout) inflater.inflate(R.layout.list_item_spinners,null);

    Spinner spinner1 = (Spinner) spinners.findViewById(R.id.spinner1);
    Spinner spinner2 = (Spinner) spinners.findViewById(R.id.spinner2);
    Spinner spinner3 = (Spinner) spinners.findViewById(R.id.spinner3);
    DebugAdapterViewListeners.set(spinner1,"spinner1");

    // VIEW SETUP
    lowRangeText.setText("text1");
    highRangeText.setText("text2");
    unitsText.setText("text3");
    // SPINNER SETUP
    String[] massUnits1 = new String[]{"one","two"};
    String[] massUnits2 = new String[]{"three","four"};
    String[] timeUnits = new String[]{"five","six"};

    ArrayAdapter<String> adapt1 = new ArrayAdapter<String>(this,R.layout.spinner_list_item_centered);
    ArrayAdapter<String> adapt2 = new ArrayAdapter<String>(this,R.layout.spinner_list_item_centered);
    ArrayAdapter<String> adapt3 = new ArrayAdapter<String>(this,R.layout.spinner_list_item_centered);
    adapt1.addAll(massUnits1);
    adapt2.addAll(massUnits2);
    adapt3.addAll(timeUnits);
    spinner1.setAdapter(adapt1);
    spinner2.setAdapter(adapt2);
    spinner3.setAdapter(adapt3);

    listadapter.addView(lowRangE);
    listadapter.addView(highRangE);
    listadapter.addView(units);
    listadapter.addView(spinners);

    contents.setAdapter(listadapter);
}


@Override
public Boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.SELEctor,menu);
    return false;
}


}

这是SimpleBaseAdapter类：

public class SimpleBaseAdapter extends BaseAdapter {

private ArrayList<View> views;
private Context context;

public SimpleBaseAdapter(Context context) {
    this.context = context;
    this.views = new ArrayList<View>();
}

public void addView(View view) {
    this.views.add(view);
}

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

@Override
public Object getItem(int position) {
    View view = views.get(position);
    if (view instanceof AbsListView) {
        return ((AbsListView)view).getItemAtPosition(position);
    } else if (view instanceof AbsSpinner) {
        return ((AbsSpinner)view).getItemAtPosition(position);
    }  else {
        return null;
    }
}

@Override
public long getItemId(int position) {
    View view = views.get(position);
    if (view instanceof AbsListView) {
        return ((AbsListView)view).getItemIdAtPosition(position);
    } else if (view instanceof AbsSpinner) {
        return ((AbsSpinner)view).getItemIdAtPosition(position);
    }  else {
        return 0;
    }
}

@Override
public View getView(int position,View convertView,ViewGroup parent) {
    return views.get(position);
}

}
