创建了自定义布局对话框，但在对话框外部单击时无法关闭对话框 window

Question

        **Please help me out where I have done wrong**
  

I am not able to dismiss dialog when clicked on the outside area on my screen only dismissed when I press backpress in mobile keys.

        Dialog dialog = new Dialog(mContext, android.R.style.Theme_Translucent_NoTitleBar);
        dialog.setContentView(R.layout.dialog_child_product_two);
        WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
        lp.dimAmount = 0.7f; // Dim level. 0.0 - no dim, 1.0 - completely opaque
        dialog.getWindow().setAttributes(lp);
        dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
        dialog.setCancelable(false);
        dialog.setCanceledOnTouchOutside(true);
        
        *// Views inflated in my dialog to perform some actions on keypress*
        Button btnDone = (Button) dialog.findViewById(R.id.txt_done);
       
        btnDone.setOnClickListener(view -> {
            // Do some work here after some action performed
            dialog.dismiss();
        });
        dialog.show();

Answer 1

您需要移除

dialog.setCancelable(false);

因为如果您希望在对话框区域外单击时关闭对话框，当您将可取消 属性 设置为 false 时，您希望它如何关闭。

Answer 2

    Dialog dialog = new Dialog(mContext);

我试过从这个对话框中删除样式 并添加了以下内容：

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

或者

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

两者都工作正常并且能够关闭外部区域点击的对话框。
