当点击BadTokenException的Andr​​oid微调异常 [英] Android Spinner Exception when clicked BadTokenException

问题描述

我有一个点击微调时（在弹出窗口）问题

I have a problem when clicking on a spinner ( in a popup window )

这是我的弹出：

public class PopupDialog extends PopupWindow  {

    public PopupDialog() {
        super();
        init();
    }

    public PopupDialog(View contentView, int width, int height) {
        super(contentView, width, height);
        init();
    }

    public PopupDialog(View contentView) {
        super(contentView);
        init();
    }

    private void init() {
        this.setTouchable(true);
        this.setFocusable(true);
        this.setOutsideTouchable(true);
        setBackgroundDrawable(new BitmapDrawable());

        this.setTouchInterceptor(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                    PopupDialog.this.dismiss();

                    return true;
                }

                return false;
            }
        });

    }

}

按钮的点击，显示在弹出：

the click of the button that shows the popup:

public void click(View v) {
        LayoutInflater layoutInflater 
         = (LayoutInflater)getBaseContext()
          .getSystemService(LAYOUT_INFLATER_SERVICE);  
        View popupView = layoutInflater.inflate(R.layout.popup, null);  
                 final PopupDialog popupWindow = new PopupDialog(
                   popupView, 
                   LayoutParams.WRAP_CONTENT,  
                         LayoutParams.WRAP_CONTENT);

                 DisplayMetrics metrics = new DisplayMetrics();
                 getWindowManager().getDefaultDisplay().getMetrics(metrics);
                 popupWindow.setHeight(metrics.heightPixels);
                 popupWindow.setWidth(300);

                 popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, v.getLeft()+v.getWidth(), 0);

    }

我有这样的例外（BadTokenException）

I have this exception ( BadTokenException )

欢迎任何帮助，谢谢提前：）

Any help is welcome, thank you in advance :)

推荐答案

有一个背景的冲突。尝试在你的XML微调声明添加此：的android：spinnerMode =对话

There is a context conflict. Try adding this in your XML spinner declaration : android:spinnerMode="dialog"
