本文深入解析了Android中SplashActivity的实现细节，包括如何使用CountDownTimer进行广告倒计时跳转，以及如何通过Intent启动MainActivity并展示插屏广告。文章还介绍了如何在Activity销毁时取消倒计时，避免内存泄漏。

package com.example.myapplication.splash;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.View;
import android.widget.TextView;


import com.example.myapplication.MainActivity;

import com.example.myapplication.R;
import com.example.myapplication.ad.AdUtils;

public class SplashActivity extends Activity implements View.OnClickListener{

    private static final String TAG = "SplashActivity";
    private TextView bt;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AdUtils.initAd(getApplicationContext());
        setContentView(R.layout.splash_layout);
        bt = findViewById(R.id.bt);
        startClock();
        bt.setOnClickListener(this);
    }

    private void startClock() {
        bt.setVisibility(View.VISIBLE);
        countDownTimer.start();
    }

    private CountDownTimer countDownTimer = new CountDownTimer(3200, 1000) {
        @Override
        public void onTick(long l) {
            bt.setText("skip ad " + l / 1000 + "s");
        }

        @Override
        public void onFinish() {
            bt.setText("skip ad " + 0 + "s");
            toMainActivity();
        }
    };

    @Override

        int id = view.getId();
        switch (id){
            case R.id.bt:
                toMainActivity();
        }
    }

    private void toMainActivity() {

        Intent intent = new Intent(SplashActivity.this, MainActivity.class);
        startActivity(intent);
        AdUtils.showInterstitial();
        finish();

    }

    @Override
    protected void onDestroy() {

        if (countDownTimer!= null){
            countDownTimer.cancel();
        }
    }
