AlertDialog主题

Question

我正在使用

<activity android:name =".ShowingDialog" 
          android:theme="@android:style/Theme.Dialog" />

在我的活动中，它正确显示对话框， 但是当对话框出现时，它会在中间显示我的项目名称，如下图所示，所以，在按下后退按钮之前我无法做任何事情。

我的项目名称是：LMP

有什么建议吗？

                                            // here you can add functions
                                            // Do nothing 




                                           }
                                        });

                                        alertDialog2.setIcon(android.R.drawable.ic_dialog_alert);
                                        alertDialog2.show();


                                }
                            });



                    alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
                    alertDialog.show();

    }

    public void sendSMS(String number, String msg) throws Exception {
        if (!b) {
            SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(number, null, msg, null, null);
        }
        b = true;
    }

===========================第二次更新================== =================

投放后：

使用visibility ="gone"的xml布局并添加以下行：

this.requestWindowFeature(Window.FEATURE_NO_TITLE);



public class ShowingDialog extends Activity {

    boolean b;
    String CancelMsg;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    //For Sending SMS with cancel Request
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.showing_dialog);
....
}}

获得的结果如下图所示：

您显示对话框的方式非常糟糕（您不应仅使用新活动来显示对话框）。我建议你改为dialogfragments。
