android – 关闭Spinner点击Spinner外面

一旦我点击了Spinner之外,我想关闭一个 Android微调器.甚至有可能吗

解决方法

我有一些运气,即使它不能完全奏效.

微调适配器的获取视图：

public View getView(int position,View v,ViewGroup parent) {
   if (v == null) {
      LayoutInflater mLayoutInflater = mActivity.getLayoutInflater();
      v = mLayoutInflater.inflate(R.layout.user_row,null);
   }

   View tempParent = (View) parent.getParent().getParent().getParent();
   tempParent.setonTouchListener(new MyOnTouchListener(mActivity));
   mActivity.setopen(true);

   User getUser = mUsers.get(position);
   return v;
}

本体聆听者：

public class MyOnTouchListener implements OnTouchListener{
   private MyActivity mOverall;
   public MyTouchListener(MyActivity overall) {
      mOverall = overall;
   }

   public boolean onTouch(View v,MotionEvent event) {
      if (mOverall.getopen()) {
         mOverall.getwindow().setContentView(R.layout.main); //reset your activity             screen
         mOverall.initMainLayout(); //reset any code.  most likely what's in your oncreate
      }
      return false;
   }  
}

在项目选择的听众：

public class MySelectedListener implements OnItemSelectedListener {
   public void onItemSelected(AdapterView<?> parent,View view,int pos,long id) {
     setUser(pos); //or whatever you want to do when the item is selected
     setopen(false);         
  }
  public void onnothingSelected(AdapterView<?> parent) {}
}

活动

您使用微调器的活动应该有一个全局变量mOpen与get和set方法.这是因为即使列表关闭后,该套头倾听者倾向于保留.

这种方法的局限性：

如果您在微调器和选项之间或选项旁边触摸,则关闭.触摸上方的微调器和下方的选项仍然不会关闭它.
