Android Dialog, keep dialog open when button is pressed?
目标:
如图

点击对话框中确定按钮之后需要判断输入是否为空,如果为空,显示toast,如果输入符合要求,那么dismiss掉对话框
参考链接:stackoverflow

代码如下:

final EditText etUserName = new EditText(context);
        mChangeNameDialog = new AlertDialog.Builder(context)
                .setTitle(ResourceUtils.getString(R.string.change_nick_name))
                .setView(etUserName)
                .setNegativeButton(ResourceUtils.getString(R.string.cancle), null)
                .setPositiveButton(ResourceUtils.getString(R.string.ok), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                    }
                }).create();
        mChangeNameDialog.show();
        mChangeNameDialog.getButton(DialogInterface.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String userName = StringUtils.toStrValue(etUserName.getText());
//判断是否为null或空字符
                if (StringUtils.isBlank(userName)) {
                    view.showToast(ResourceUtils.getString(R.string.please_input_nick_name));
                    return;
                }
                //判断昵称是否含有空格
                if (StringUtils.hasWhiteSpace(userName)) {
                    view.showToast(ResourceUtils.getString(R.string.has_white_space));
                    return;
                }

                dismissDialog();

                //do something
            }
        });
