在自定义的Dialog中有的含有EditText组件，需要在dialog显示的时候使EditText获取焦点，并且显示软件盘。

上代码：

public class AlertDialog extends Dialog implements        View.OnClickListener {    private Context context;    private CallBackListener listener;    public AlertDialog(Context context, int theme, CallBackListener listener) {        super(context, theme);   //传入主题，隐藏默认背景        // TODO Auto-generated constructor stub       this.context = context;        this.listener = listener;    }    @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);   //不适用Dialog的Title        init();    }    public void init() {        LayoutInflater inflater = LayoutInflater.from(context);        View view = inflater.inflate(R.layout.activity_buy_bag, null);        setContentView(view);        view.findViewById(R.id.dialog_ok).setOnClickListener(this);           view.findViewById(R.id.dialog_cancel).setOnClickListener(this);               view.findViewById(R.id.buy_bag_imageView4).setOnClickListener(this);        view.findViewById(R.id.buy_bag_imageView5).setOnClickListener(this);        Window dialogWindow = getWindow();        WindowManager.LayoutParams lp = dialogWindow.getAttributes();        DisplayMetrics d = context.getResources().getDisplayMetrics();        lp.width = (int) (d.widthPixels * 0.8); //        dialogWindow.setAttributes(lp);        //设置为手机宽度的0.8        setOnShowListener(new OnShowListener() {            public void onShow(DialogInterface dialog) {                InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);                imm.showSoftInput(edt, InputMethodManager.SHOW_IMPLICIT);            }        });    }    @Override    public void onClick(View arg0) {        switch (arg0.getId()) {            case R.id.dialog_ok:

      listener.getSingleEdtNum(X x,X x ....);  //接口回调
                dismiss();

break;

           case R.id.dialog_cancel:

                dismiss();

                break;

          case R.id.buy_bag_imageView5:   //“加操作”

                break;

          case R.id.buy_bag_imageView4:  //“减操作”

                break;

      public interface CallBackListener {

      public void getSingleEdtNum(X x, X,x.....);  //activity实现接口    }}
