需求：点击GridView中的条目弹出AlertDialog询问用户操作

代码：

gridView.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {               AlertDialog dialog = new AlertDialog.Builder(XXXXActivity.this)                        .setTitle(getString(R.string.prompt))                        .setCancelable(false)                        .setMessage(getText(R.string.really_preview_program))                        .setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {                            @Override                            public void onClick(DialogInterface dialogInterface, int i) {                                                            }                        })                        .setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {                            @Override                            public void onClick(DialogInterface dialogInterface, int i) {                                dialogInterface.cancel();                            }                        }).create();                dialog.show();}});

问题：

02-26 15:07:16.064 8946-8946/xxx.xxx.xxx.xxx E/AndroidRuntime﹕ FATAL EXCEPTION: main
android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@418a5de8 is not valid; is your activity running?

分析：

Context传递错误，原因在于当前Activity所在的tabhost还有更上层的Activity。

解决方案：

创建Dialog时候使用：

 AlertDialog dialog = new AlertDialog.Builder(XXXXActivity.this.getParent())
