android闪屏(普通闪屏、倒计时闪屏、倒计时+动画闪屏)

一、项目目录结构

二、activity_main.xml代码

三、activity_splashscreen.xml代码

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);

		/********************************************************************************

		/*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);
	}
}
