Just remove android:padding="1dip"from Spinner TableRow and try i am not sure just try
只需android:padding="1dip"从 Spinner TableRow 中删除并尝试我不确定只是尝试
Edit:
You have to use a custom view here to give alignment to the Spinner values. Create a CustomView like thisanswer has created and add android:gravity' to the TextView asright`.
编辑：您必须在此处使用自定义视图来对齐 Spinner 值。创建一个像这个答案已经创建的android:gravity' to the TextView asCustomView并添加right`。
And set the CustomView to your adapter using
并使用将 CustomView 设置为您的适配器
adapter.setDropDownViewResource(android.R.layout.your_custom_created_view);

I think you should use custom ArrayAdapterwith TextViewand play with textview property as per your requirement.
我认为您应该根据您的要求使用 custom ArrayAdapterwithTextView并使用 textview 属性。
Example :
例子 ：
MyAdapter.java
我的适配器
public class MyAdapter extends ArrayAdapter {
Context context;
public MyAdapter(Context context, int resource) {
super(context, resource);
this.context=context;
// TODO Auto-generated constructor stub
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view=inflater.inflate(R.layout.mylayout, parent,false);
TextView textView=(TextView)view.findViewById(R.id.text);
return view;
}
}
mylayout.xml
布局文件
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/text"
android:layout_width="match-parent"
android:layout_height="wrap_content"
android:text="@string/lblPros"
android:textSize="14sp"
android:gravity="right"
android:textStyle="bold" />
</LinearLayout>

Try this:-
尝试这个：-
use android:layout_span="1". if required then give left margin for the first row.
使用 android:layout_span="1"。如果需要，则为第一行提供左边距。
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="@drawable/roundshape" >
<!-- Lable Area -->
<TableRow
android:id="@+id/tblRwspnLbl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center" ">
<TextView
android:id="@+id/lblCust"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/lblCust"
android:layout_span="1"
android:textSize="14sp"
android:textStyle="bold"
android:gravity="left"/>
<TextView
android:id="@+id/lblPros"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_span="1"
android:text="@string/lblPros"
android:textSize="14sp"
android:textStyle="bold" />
</TableRow>
<!-- Spinner Area -->

This is sample code it may useful
这是可能有用的示例代码
<Spinner
android:id="@+id/spinner1"
style="?android:attr/spinnerStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginBottom="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp"
android:background="@drawable/dropdown"
android:dropDownVerticalOffset="1dp"
android:focusable="false"
android:spinnerMode="dropdown" />
take one more layout for the text view following is the code for layout
为文本视图再做一个布局，下面是布局代码
spinner_text_layout.xml
spinner_text_layout.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text_for_spinner"
style="?android:attr/spinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawablePadding="10dp"
android:drawableRight="@drawable/arrow"
android:gravity="center"
android:textColor="@android:color/white" >
</TextView>
now in the custom adapter these are the two methods
现在在自定义适配器中，这是两种方法
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(
R.layout.spinner_text_layout, null);
}
TextView textView = (TextView) convertView
.findViewById(R.id.text_for_spinner);
textView.setText((String) getItem(position));
notifyDataSetChanged();
return convertView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(
R.layout.spinner_text_layout, null);
}
TextView textView = (TextView) convertView
.findViewById(R.id.text_for_spinner);
textView.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0, 0);
textView.setText((String) getItem(position));
textView.setTextColor(Color.BLACK);
textView.setBackgroundResource(R.drawable.drop_down_selector);
return convertView;
}
