MainActivity中調用

package com.example.mydialog;import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle; import android.util.Log;public class MainActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//-----------------------------------OKCancelTipsDialog logInOtherDivice = new OKCancelTipsDialog(MainActivity.this, "下線通知","你的賬號已經在其它設備登陸,如非本人操作,請及時修改密碼", "確定","Hello");logInOtherDivice.setClicklistener(new OKCancelTipsDialog.DialogClickListenerInterface() {@Overridepublic void doOk() {Log.d("OK","66666");}@Overridepublic void doCancel() {Log.d("OdoCancel","66666");}});logInOtherDivice.show();}}
