自定义对话框未显示-Android

Question

我正在尝试弹出一个自定义对话框，当我点击一个按钮，但它不会弹出在所有。我的应用程序基本上是一个日历，我将使用sqlite在日历中添加/保留约会和其他内容，使用对话框，这是指定约会细节的地方。

我为此使用的代码如下：

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);
    }

我做错了什么？

Answer 1

为对话框调用show()方法。

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