public class CustomSpinnerAdapter extends BaseAdapter{
private Context context;
private ArrayList<String> arr;

public CustomSpinnerAdapter(Context context, int textViewResourceId,
        ArrayList<String> objects) {

    // TODO Auto-generated constructor stub
    this.context = context;
    arr = objects;
}

@Override
public View getDropDownView(int position, View convertView,
        ViewGroup parent) {
    // TODO Auto-generated method stub
    return getCustomView(position, convertView, parent);
}

@Override

    // TODO Auto-generated method stub
    return getCustomView(position, convertView, parent);
}

public View getCustomView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    //return super.getView(position, convertView, parent);

    LayoutInflater mInflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row=mInflater.inflate(R.layout.spinner_item, parent, false);

    TextView accountNumber = (TextView) row
            .findViewById(R.id.accountNumber);
    TextView accountType = (TextView) row
            .findViewById(R.id.accountType);
    TextView balance = (TextView) row
            .findViewById(R.id.balance);
    accountNumber.setText("accountType");
    balance.setText("balance");
    accountType.setText("accountNumber");
    return row;
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return arr.size();
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return  arr.get(position);
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}

}

当我打电话给这个班级的时候，我的旋转器的高度非常长......

spinner_item

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
 android:orientation="vertical"
android:layout_height="wrap_content" >
<TextView
    android:id="@+id/accountNumber"
    style="@style/listViewPrimaryDetail"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:paddingLeft="10dp"
    android:paddingTop="10dp" />
<TextView
    android:id="@+id/accountType"
    style="@style/listViewSecondaryDetail"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@id/accountNumber"
    android:ellipsize="marquee"
    android:paddingBottom="10dp"
    android:paddingLeft="10dp" />
<TextView
    android:id="@+id/balance"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:layout_alignParentRight="true"
    android:ellipsize="marquee" />
   </RelativeLayout>

那会发生什么？怎么了？

         Spinner spinner = (Spinner) rootView
                    .findViewById(R.id.planets_spinnerqw);
            CustomSpinnerAdapter adapter = new CustomSpinnerAdapter(
                    container.getContext(),R.layout.spinner_item, values);
            // Apply the adapter to the spinner
            spinner.setAdapter(adapter);

那为什么这段代码不起作用？在活动中我读取了微调器..分配给它自定义适配器..在自定义适配器我指定布局spinner_item ..它采取整个高度而不是我想要的设计。如果我在spinner_item中指定相对布局而不是wrap_content layout_height =＆＃34; 100dp＆＃34;它效果更好......为什么会发生这种情况？

Android自定义微调器占据整个高度
