默认情况下,AlertDialog负按钮突出显示

Question

我正在使用带有两个按钮的警告对话框.这里的问题是每当我的警告对话框显示时,其显示的负按钮都会突出显示.这个对话框中只发生这种情况,其他工作正常.请提出一些解决方法.

这是代码:

---

AlertDialog.Builder alert = new AlertDialog.Builder(context);

            alert.setTitle("Stop On The Go!");
            alert.setMessage(getResources().getString(R.string.tx_confirm_msg_journey));
            alert.setPositiveButton("Stop",
                    new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                            stopTask();
                        }
                    });
            alert.setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                            navigateToHomePage();
                            dialog.cancel();
                        }
                    });

            alert.show();

显示以下代码只需更改一行. alert.show().getButton(DialogInterface.BUTTON_POSITIVE).requestFocus();

 AlertDialog.Builder alert = new AlertDialog.Builder(getApplicationContext());

    alert.setTitle("Stop On The Go!");
    alert.setMessage(getResources().getString(R.string.tx_confirm_msg_journey));
    alert.setPositiveButton("Stop",
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {

                    stopTask();
                }
            });
    alert.setNegativeButton("Cancel",
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {

                    navigateToHomePage();
                    dialog.cancel();
                }
            });

    alert.show().getButton(DialogInterface.BUTTON_POSITIVE).requestFocus();

只是专注于积极

在您的肯定按钮中添加此行

 alertDialog.setOnShowListener(new DialogInterface.OnShowListener(){

        @Override
        public void onShow(DialogInterface dialog) {

            Button positive= alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
            positive.setFocusable(true);
            positive.setFocusableInTouchMode(true);
            positive.requestFocus();
        }
    });
