自定义对话框中的按钮| Android的
点击“短信”按钮，我弹出一个对话框。
短信按钮仅在文本字段的长度大于0时有效。（非空...）
这是方法“短信”按钮调用onClick。
private void smsPopUp() {
// TODO Auto-generated method stub
final Dialog smsDialog = new Dialog(this);
Button cancelsms = (Button)smsDialog.findViewById(R.id.smsCancel);
smsDialog.setContentView(R.layout.sms_dialog);
smsDialog.setTitle("To: " + numberfield.getText());
cancelsms.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
smsDialog.dismiss();
}
});
smsDialog.show();
}
如果我注释掉该方法的onClick内部，则会弹出对话框，其中包含两个按钮：取消和发送。基本上，它工作..没有按钮工作。 如果我运行此代码......我会收到错误..

我考虑过制作一个警报对话框，这显然有点容易。 但是我不确定我是否可以为“正面按钮”定制onClick ...因为“发送”onClick上会有很多代码
sms_dialog（.xml）
的屏幕截图（只有顶部显示在对话框中（Textfield + 2按钮）。）

反转以下陈述
Button cancel = (Button)smsDialog.findViewById(R.id.smsCancel);
smsDialog.setContentView(R.layout.sms_dialog);
应该是
smsDialog.setContentView(R.layout.sms_dialog);
Button cancel = (Button)smsDialog.findViewById(R.id.smsCancel);
您需要先将布局发送到对话框，然后初始化视图。
