Android自定义Spinner下拉列表（使用ArrayAdapter和自定义Adapter实现）

<span style="font-size:16px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"

  <Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
   />
</LinearLayout></span>

<span style="font-size:16px;"><?xml version="1.0" encoding="utf-8"?>
<resources>
  <string-array name="spinnername">
    <item>北京</item>
    <item>上海 </item>
    <item>广州</item>
    <item>深圳</item>
  </string-array>
</resources></span>

    // 初始化控件
mSpinner = (Spinner) findViewById(R.id.spinner1);
// 建立数据源

//绑定 Adapter到控件
mSpinner.setAdapter(_Adapter);

mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

      int position, long id) {
    String str=parent.getItemAtPosition(position).toString();
    Toast.makeText(SpinnerActivity.this, "你点击的是:"+str, 2000).show();
  }
  @Override
