我有这个
和这个
使用这些xml代码
名为 spinadapt.xml 的适配器的 xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#fff" >
<TextView
android:id="@+id/tvCust"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_toLeftOf="@+id/radioButton1"
android:gravity="left|center_vertical"
android:textColor="#000"
android:textSize="15sp" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentRight="true" />
</RelativeLayout>
和名为 activity_main.xml 的主布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:hint="Select item"
android:background="@drawable/spin"/>
</RelativeLayout>
java代码是名为MainActivity.java的类
public class MainActivity extends Activity
{
Spinner sp;
TextView tv;
String[] counting={"One","Two","Three","Four"};
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sp=new Spinner(this);
tv=(TextView)findViewById(R.id.spinner1);
tv.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
sp.performClick();
}
});
sp.setAdapter(new Adapter(MainActivity.this, counting));
sp.setOnItemSelectedListener(new OnItemSelectedListener()
{
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
tv.setText(counting[arg2]);
}
@Override
public void onNothingSelected(AdapterView<?> arg0)
{
}
});
}
}
和名为 Adapter.java 的适配器类
public class Adapter extends BaseAdapter
{
LayoutInflater inflator;
String[] mCounting;
public Adapter( Context context ,String[] counting)
{
inflator = LayoutInflater.from(context);
mCounting=counting;
}
@Override
public int getCount()
{
return mCounting.length;
}
@Override
public Object getItem(int position)
{
return null;
}
@Override
public long getItemId(int position)
{
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
convertView = inflator.inflate(R.layout.spinadapt, null);
TextView tv = (TextView) convertView.findViewById(R.id.tvCust);
tv.setText(Integer.toString(position));
return convertView;
}
}
这是完美的工作
希望这会有所帮助
