Question

我使用此代码创建了自定义对话框：

public void showEditTextModalWindow(View view) {

    final Dialog dialog = new Dialog(PodShipmentDetail.this);
    dialog.setTitle("Edit shipment note");
    dialog.setContentView(R.layout.alert_dialog_custom);

    dialog.show();
    Log.i(GlobalApplication.APP_LOG_NAMESPACE, "SHOW DIALOG");
}

我想问一下，如何用onClick监听器以编程方式添加OK和Cancel按钮..

这样的事情：

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
// Do nothing but close the dialog
   dialog.dismiss();
}
});

我不想在XML中添加按钮，因为我希望设计中的按钮通常适用于Android中的警报对话框（不是灰色的，不是丑陋的）..

感谢您的任何建议。

如何显示对话框：

AlertDialog alertDialog = new AlertDialog(context);
alertDialog.setTitle("Custom Dialog");
alertDialog.setMessage("Custom Dialog!!\n\n\n(Facebook.com/Awais.is.King)");
alertDialog.show();

Answer 2

添加确定按钮或取消并添加此代码：

Button btnOk = (Button) dialog.findViewById(R.id.dialogButton);
btnOk.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
      dialog.dismiss();
   }
});

所以这应该是这样的：

public void showEditTextModalWindow(View view) {

    final Dialog dialog = new Dialog(PodShipmentDetail.this);
    dialog.setTitle("Edit shipment note");
    dialog.setContentView(R.layout.alert_dialog_custom);

    Button btnOk = (Button) dialog.findViewById(R.id.dialogButton);
    btnOk.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
          dialog.dismiss();
       }
    });

    dialog.show();
    Log.i(GlobalApplication.APP_LOG_NAMESPACE, "SHOW DIALOG");
}

Android，如何以编程方式将取消和确定按钮添加到自定义对话框？
