自定义dialog

final AlertDialog ad = new android.app.AlertDialog.Builder(context).create(); ad.setCanceledOnTouchOutside(true); ad.show();        //关键在下面的两行,使用window.setContentView,替换整个对话框窗口的布局        Window window = ad.getWindow();        window.setContentView(R.layout.alert_dialog);        View tv_copy = window.findViewById(R.id.tv_copy);        tv_copy.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {ToastUtils.showToast("复制", context);ad.dismiss();}});
