自定義對話框未顯示-Android

Question

當我單擊一個按鈕時，我試圖彈出一個自定義對話框，但根本不會彈出。 我的應用程序基本上是一個日歷，我將使用sqlite通過對話框在日歷中的日期中添加/保留約會和內容，在該對話框中將指定約會詳細信息。

我為此使用的代碼如下：

public void onClick(View v) {
        // TODO Auto-generated method stub
        //long a = calendar.getDate();
        switch(v.getId()){
        case R.id.createButton:
            openCreateAppointmentDialog();
            break;
        }
    }

    private void openCreateAppointmentDialog(){
        Context mContext = getApplicationContext();
        Dialog createAppmntDialog = new Dialog(mContext);

        createAppmntDialog.setContentView(R.layout.create);
        createAppmntDialog.setTitle(R.string.createTitle);

        appointmentTitle = (EditText) createAppmntDialog.findViewById(R.id.titleTextBox);
        appointmentTitle.setText("hello");

        appointmentTime = (EditText) createAppmntDialog.findViewById(R.id.timeTextBox);

        appointmentDetails = (EditText) createAppmntDialog.findViewById(R.id.detailsTextBox);

        saveAppointment = (Button) createAppmntDialog.findViewById(R.id.saveButton);
        saveAppointment.setOnClickListener(this);
    }

我究竟做錯了什么？

Answer 1

調用對話框的show()方法。

createAppmntDialog.show(); //when you want the dialog to appear on the screen
