Android开发欢迎页点击跳过倒计时进入主页

没点击跳过自然进入主页，点击跳过之后立即进入主页

1.欢迎页布局activity_sp.xml放一张背景图（图片随你便啦）再放一个盛放倒计时的TextView

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@drawable/a">

<RelativeLayout

android:layout_width="match_parent"

android:layout_height="wrap_content">

<TextView

android:id="@+id/tv"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentRight="true"

android:layout_marginRight="20dp"

android:layout_marginTop="10dp"

android:textSize="20sp" />

</RelativeLayout>

</LinearLayout>

2.主要java代码

package com.cwj.test;

import android.content.Intent;

import android.os.Handler;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.view.WindowManager;

import android.widget.TextView;

import java.util.Timer;

import java.util.TimerTask;

public class SpActivity extends AppCompatActivity implements View.OnClickListener {

private int recLen = 5;//跳过倒计时提示5秒

private TextView tv;

Timer timer = new Timer();

private Handler handler;

private Runnable runnable;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//定义全屏参数

int flag= WindowManager.LayoutParams.FLAG_FULLSCREEN;

//设置当前窗体为全屏显示

getWindow().setFlags(flag, flag);

setContentView(R.layout.activity_sp);

initView();

timer.schedule(task, 1000, 1000);//等待时间一秒，停顿时间一秒

/**

* 正常情况下不点击跳过

handler = new Handler();

handler.postDelayed(runnable = new Runnable() {

@Override

public void run() {

//从闪屏界面跳转到首界面

Intent intent = new Intent(SpActivity.this, MainActivity.class);

startActivity(intent);

finish();

}

}, 5000);//延迟5S后发送handler信息

}

private void initView() {

tv = findViewById(R.id.tv);//跳过

tv.setOnClickListener(this);//跳过监听

}

TimerTask task = new TimerTask() {

@Override

public void run() {

runOnUiThread(new Runnable() { // UI thread

@Override

public void run() {

recLen--;

tv.setText("跳过 " + recLen);

if (recLen < 0) {

timer.cancel();

tv.setVisibility(View.GONE);//倒计时到0隐藏字体

}

});

}

};

/**

* 点击跳过

@Override

public void onClick(View view) {

switch (view.getId()) {

case R.id.tv:

//从闪屏界面跳转到首界面

Intent intent = new Intent(SpActivity.this, MainActivity.class);

startActivity(intent);

finish();

if (runnable != null) {

handler.removeCallbacks(runnable);

}

break;

default:

break;

}

这里style里改了样式，没有标题栏Theme.AppCompat.Light.NoActionBar

<item name="colorPrimary">@color/colorPrimary</item>

<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

<item name="colorAccent">@color/colorAccent</item>

</style>
