這篇文章主要介紹了Android中閃屏實現(xiàn)方法小結(普通閃屏、倒計時閃屏、倒計時+動畫閃屏),非常不錯，代碼簡單易懂，需要的朋友可以參考下

一、項目目錄結構

二、activity_main.xml代碼

<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="主頁面" /> 
</RelativeLayout>

三、activity_splashscreen.xml代碼

<?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代碼

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); 
    // 通過下面兩行代碼也可實現(xiàn)全屏無標題欄顯示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);*/ 
    /********************************************************************************

    /*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);*/ 
    /******************************************************************************** 
     * 
     * 倒計時+動畫閃屏實現(xiàn)方式 
     * 
     * ******************************************************************************/ 
    MyCountDownTimer mc = new MyCountDownTimer(4000, 1000);  
    mc.start(); 
    new Handler().postDelayed(new Runnable() { 
      @Override 
      public void run() { 
        //左移動畫 
        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); //設置動畫執(zhí)行的時間 
        ta.setFillAfter(true);//當動畫結束后 動畫停留在結束位置,然后等啟動主界面后將其銷毀 
        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:倒計時的總數(shù),單位毫秒 
    //例如 millisInFuture=1000;表示1秒 
    //countDownInterval:表示間隔多少毫秒,調(diào)用一次onTick方法() 
    //例如: countDownInterval =1000;表示每1000毫秒調(diào)用一次onTick() 
    public MyCountDownTimer(long millisInFuture, long countDownInterval) {  
      super(millisInFuture, countDownInterval);  
    }  
    public void onFinish() {  
      tv_countDown.setText("開始跳轉(zhuǎn)……"); 
    }  
    public void onTick(long millisUntilFinished) {  
      tv_countDown.setText("倒計時(" + millisUntilFinished / 1000 + ")"); 
    }  
  } 
}

五、MainActivity.java代碼

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); 
    //為了讓閃屏結束后更自然的過度到主界面，去除主界面的啟動動畫，將下面函數(shù)的第一個參數(shù)設為0即可 
    overridePendingTransition(0, 0); 
  } 
}
