Android中闪屏实现方法小结(普通闪屏、倒计时闪屏、倒计时+动画闪屏)
作者:songyi160
这篇文章主要介绍了Android中闪屏实现方法小结(普通闪屏、倒计时闪屏、倒计时+动画闪屏),非常不错,代码简单易懂,需要的朋友可以参考下
一、项目目录结构
二、activity_main.xml代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.zgs.SplashScreenByXml.MainActivity" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="主页面" /> </RelativeLayout>
三、activity_splashscreen.xml代码
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/splash" android:orientation="vertical" android:id="@+id/ll_splashActivity"> <TextView android:id="@+id/tv_countDown" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="end" android:layout_marginEnd="20dp" android:layout_marginTop="20dp" android:textColor="@android:color/white" android:textSize="20sp" /> </LinearLayout>
四、SplashScreenActiviy.java代码
package com.zgs.SplashScreenByXml; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.os.CountDownTimer; import android.os.Handler; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.view.animation.Animation; import android.view.animation.Animation.AnimationListener; import android.view.animation.TranslateAnimation; import android.widget.LinearLayout; import android.widget.TextView; import com.zgs.CommonlySplashScreen.R; public class SplashScreenActiviy extends Activity { private TextView tv_countDown; private LinearLayout ll_splashActivity; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 通过下面两行代码也可实现全屏无标题栏显示activity // getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_splashscreen); tv_countDown = (TextView) findViewById(R.id.tv_countDown); ll_splashActivity = (LinearLayout) findViewById(R.id.ll_splashActivity); /******************************************************************************** * * 普通闪屏实现方式 * * ******************************************************************************/ /*new Handler().postDelayed(new Runnable() { @Override public void run() { Intent intent = new Intent(getApplicationContext(), MainActivity.class); startActivity(intent); finish(); } }, 1000*4);*/ /******************************************************************************** * * 倒计时闪屏实现方式 * * ******************************************************************************/ /*MyCountDownTimer mc = new MyCountDownTimer(4000, 1000); mc.start(); new Handler().postDelayed(new Runnable() { @Override public void run() { Intent intent = new Intent(getApplicationContext(), MainActivity.class); startActivity(intent); finish(); } }, 1000*4);*/ /******************************************************************************** * * 倒计时+动画闪屏实现方式 * * ******************************************************************************/ MyCountDownTimer mc = new MyCountDownTimer(4000, 1000); mc.start(); new Handler().postDelayed(new Runnable() { @Override public void run() { //左移动画 TranslateAnimation ta = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 0, Animation.RELATIVE_TO_PARENT, -1, Animation.RELATIVE_TO_PARENT, 0, Animation.RELATIVE_TO_PARENT, 0); ta.setDuration(2000); //设置动画执行的时间 ta.setFillAfter(true);//当动画结束后 动画停留在结束位置,然后等启动主界面后将其销毁 ll_splashActivity.startAnimation(ta); ta.setAnimationListener(new AnimationListener() { @Override public void onAnimationStart(Animation arg0) { } @Override public void onAnimationRepeat(Animation arg0) { } @Override public void onAnimationEnd(Animation arg0) { Intent intent = new Intent(getApplicationContext(), MainActivity.class); startActivity(intent); finish(); } }); } }, 1000*4); } class MyCountDownTimer extends CountDownTimer { //millisInFuture:倒计时的总数,单位毫秒 //例如 millisInFuture=1000;表示1秒 //countDownInterval:表示间隔多少毫秒,调用一次onTick方法() //例如: countDownInterval =1000;表示每1000毫秒调用一次onTick() public MyCountDownTimer(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); } public void onFinish() { tv_countDown.setText("开始跳转……"); } public void onTick(long millisUntilFinished) { tv_countDown.setText("倒计时(" + millisUntilFinished / 1000 + ")"); } } }
五、MainActivity.java代码
package com.zgs.SplashScreenByXml; import android.app.Activity; import android.os.Bundle; import com.zgs.CommonlySplashScreen.R; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //为了让闪屏结束后更自然的过度到主界面,去除主界面的启动动画,将下面函数的第一个参数设为0即可 overridePendingTransition(0, 0); } }
