在Android开发中打开网络设置出错，点击后直接退出而不是打开网络设置 怎么会事啊

Question

private void showSetNetworkDialog() {
AlertDialog.Builder builder = new Builder(this);
builder.setTitle("设置网络");
builder.setMessage("网络错误请检查网络链接");
builder.setPositiveButton("设置网络", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent();
intent.setClassName("com.android.settings", "com.android.settings.WirelessSettings");
startActivity(intent);
finish();
}
});
builder.setNegativeButton("取消", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
finish();

}
});
builder.create().show();

}
