问题描述

当我点击ListView item时如何关闭AlertDialog？

下面是 dialog 代码，在 dialog 中有一个 ListView，我想在点击 ListView item 时关闭AlertDialog：

public void createSearchDialog(final String[] Memo){        LayoutInflater factory = LayoutInflater.from(this);        View searchView = factory.inflate(R.layout.seach_dialog null);            lv = (ListView) searchView.findViewById(R.id.search_list);        lv.setAdapter(new MyPerformanceArrayAdapter(this Memo memo_PW));        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {            public void onItemClick(AdapterView<?> arg0 View view int positionlong arg3) {                // TODO Auto-generated method stub                         /// close dialog            }        });        searchBuilder = new AlertDialog.Builder(this);        searchBuilder.setTitle(""Search"")               .setView(searchView)               .setNegativeButton(""Back"" new DialogInterface.OnClickListener() {                               public void onClick(DialogInterface arg0 int arg1) {                    // TODO Auto-generated method stub                }            })               .show();         }

我想在onItemClick()方法中加入代码

但是不能执行。
怎么处理？

解决方案

private void windowDialog(){      Window mWindow = newDialogView();      mWindow.setContentView(R.layout.kl_dialog_invite_code);      ListView listview=mWindow.findViewById(R.id.xxx);      //在onItemClick事件中调用mDialog.dismiss();就ok了}private Window newDialogView() {        if (mDialog == null) {            mDialog = new Dialog(this R.style.mydialog);            mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);        }        mDialog.show();        mDialog.setCanceledOnTouchOutside(true);        mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));        Window win = mDialog.getWindow();        WindowManager.LayoutParams lp = win.getAttributes();        // lp.alpha = 0.9f;        win.setAttributes(lp);        // WindowManager.LayoutParams.FLAG_DIM_BEHIND 背景渐变        // WindowManager.LayoutParams.FLAG_BLUR_BEHIND 背景模糊        win.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);        return win;}

解决方案二：

searchBuilder.dismiss().

是这个关闭吗
