java在5秒后加载新活动

Question

嗨，我一直在寻找让我的安卓应用程序加载StartActivity的方法。java 5秒钟，然后加载到MainActivity。java一次5秒就结束了。我发现的任何例子都不适用于我。我想知道是否有人能给我指出正确的方向

任何帮助都将不胜感激

package com.example.testerrquin.euro2016fanguide;
import 安卓.support.v7.app.AppCompatActivity;
import 安卓.os.Bundle;

public class StartActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_start);

new CountDownTimer(5000, 1000) {

        public void onTick(long millisUntilFinished) {


        }

        public void onFinish() {

        }

    }.start();
}}

AndroidManifest。xml

<?xml version="1.0" encoding="utf-8"?>`<manifest xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
package="com.example.testerrquin.euro2016fanguide" >

<application

    <activity
        安卓:name=".StartActivity"

        安卓:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action 安卓:name="安卓.intent.action.MAIN" />

            <category 安卓:name="安卓.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Answer 1

只需移除finish（）并重试

new Handler().postDelayed(new Runnable() {
   @Override
   public void run() {
   Intent startNewActivity = new Intent(CurrentActivity.this, MainActivity.class);
   startActivity(startNewActivity);

   }
}, 5000);

Answer 2

试试这个

public class StartActivity extends AppCompatActivity {

    protected int SECONDS = 5;
    Handler handler = new Handler();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_start);

        handler.removeCallbacks(runnable);
        handler.postDelayed(runnable, 1000);

    }

    private Runnable runnable = new Runnable() {
        public void run() {
            long currentMilliseconds = System.currentTimeMillis();
            SECONDS ;
            if (SECONDS > 0) {
                handler.postAtTime(this, currentMilliseconds);
                handler.postDelayed(runnable, 1000);
            } else {
                Intent it = new Intent(StartActivity.this, MainActivity.class);
                startActivity(it);
                handler.removeCallbacks(runnable);
                finish();
            }
        }
    };  
}

主要技巧是使用handler.postDelayed

希望它能有所帮助
