android - 警报对话框主题

Question

我在用着

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

在我的活动中，它正确显示了对话框，但是当对话框出现时，它在中间显示了我的项目名称，如下图所示，所以，在我按下返回按钮之前，我什么也做不了。

我的项目名称是：LMP

有什么建议么？

                                                }

                                           }

                                        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===================== ===============

放好后：

xml 布局visibility ="gone"并添加此行：

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);
....
}}

得到的结果如下图所示：

您显示对话框的方式非常糟糕（您不应该只使用新活动来显示对话框）。我建议您改为查看对话框片段。
