如何在进度对话框中设置取消按钮? [英] How to set a cancel button in Progress Dialog?

问题描述

我想在我的ProgressDialog中设置一个取消按钮.下面是我的代码:

I want to set a cancel button in my ProgressDialog. Below is my code:

myDialog = new ProgressDialog(BaseScreen.this);
myDialog.setMessage("Loading...");
myDialog.setCancelable(false);
myDialog.show();

我想在此ProgressDialog上设置带有onClickListener的按钮. 我尝试使用以下代码:

I want to set a button with an onClickListener on this ProgressDialog. I tried with this code:

myDialog.setButton("Cancel", new OnClickListener() {        
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // TODO Auto-generated method stub          
        myDialog.dismiss();
    }
});

但是它不起作用.我也尝试过其他类似的听众，但仍然没有成功. 我该如何解决这个问题?

But it isn't working. I tried other similar listeners also, but still no success. How can I solve this problem?

推荐答案

已弃用您正在使用的setButton方法(尽管它仍然可以使用).另外，您可能想要添加之前按钮来显示对话框.试试:

The setButton method you are using is deprecated (although it should still work). Also, you might want to add the button before showing the dialog. Try:

myDialog = new ProgressDialog(BaseScreen.this);
myDialog.setMessage("Loading...");
myDialog.setCancelable(false);
myDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        myDialog.dismiss();//dismiss dialog
    }
});
myDialog.show();
