Android实现动态切换组件背景的方法

scv_setAddressBg.setOnClickListener(new OnClickListener() {
       
      @Override
      public void onClick(View v) {
        int which = sp.getInt("which", 0);
        final String[] items = {"半透明","活力橙","卫士蓝","金属灰","苹果绿"};
        AlertDialog.Builder builder = new Builder(SettingActivity.this);
        builder.setTitle("设置归属地显示背景");
        builder.setSingleChoiceItems(items, which, new DialogInterface.OnClickListener() {
           
          @Override
          public void onClick(DialogInterface dialog, int which) {
            Editor edit = sp.edit();
            edit.putInt("which", which);
            edit.commit();
            scv_setAddressBg.setDesc(items[which]);
            dialog.dismiss();
          }
        });
        builder.setNegativeButton("取消", null);
        builder.show();
      }
    });
