閃屏：在打開(kāi)App時(shí)，展示，持續(xù)數(shù)秒后，自動(dòng)關(guān)閉，進(jìn)入另外的一個(gè)界面,SplashActivity跳轉(zhuǎn)到MainActivity
Android中有三種實(shí)現(xiàn)方法
xml代碼：
<?xml version="1.0" encoding="utf-8"?><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" tools:context="com.example.administrator.test.SplashActivity"> <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/splash_iv" android:scaleType="fitXY" android:src="@mipmap/splash"/></RelativeLayout>
（1）利用Handler對(duì)象的postDelayed方法可以實(shí)現(xiàn)，傳遞一個(gè)Runnable對(duì)象和一個(gè)需要延時(shí)的時(shí)間即可
new Handler().postDelayed(new Runnable() { @Override public void run() { Intent intent=new Intent(SplashActivity.this,MainActivity.class); startActivity(intent); SplashActivity.this.finish(); } },3000);（2）使用動(dòng)畫(huà)持續(xù)時(shí)間，動(dòng)畫(huà)結(jié)束后進(jìn)行跳轉(zhuǎn)
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_splash); iv =(ImageView)findViewById(R.id.splash_iv); iv.setImageResource(R.mipmap.splash); //設(shè)置透明度動(dòng)畫(huà)從無(wú)到有 AlphaAnimation alphaAnimation=new AlphaAnimation(0.0f,1.0f); //設(shè)置動(dòng)畫(huà)持續(xù)時(shí)間 alphaAnimation.setDuration(3000); //開(kāi)始顯示動(dòng)畫(huà) iv.startAnimation(alphaAnimation); //給動(dòng)畫(huà)設(shè)置監(jiān)聽(tīng)，在動(dòng)畫(huà)結(jié)束的時(shí)候進(jìn)行跳轉(zhuǎn) alphaAnimation.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { //動(dòng)畫(huà)開(kāi)始時(shí)執(zhí)行 Log.e("TAG", "onAnimationStart: " ); } @Override public void onAnimationEnd(Animation animation) { //動(dòng)畫(huà)結(jié)束時(shí)執(zhí)行 Log.e("TAG", "onAnimationEnd: " ); Intent intent=new Intent(SplashActivity.this,MainActivity.class); startActivity(intent); finish(); } @Override public void onAnimationRepeat(Animation animation) { //動(dòng)畫(huà)重復(fù)播放時(shí)執(zhí)行 Log.e("TAG", "onAnimationRepeat: " ); } }); }（3）利用Timer定時(shí)器實(shí)現(xiàn)，
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_splash); iv =(ImageView)findViewById(R.id.splash_iv); iv.setImageResource(R.mipmap.splash); Timer timer=new Timer(); timer.schedule(new TimerTask() { @Override public void run() { Intent intent=new Intent(SplashActivity.this,MainActivity.class); startActivity(intent); finish(); } },3000); }以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持武林網(wǎng)。
