Android实现闪屏页效果

本文实例为大家分享了Android实现闪屏页效果的具体代码，供大家参考，具体内容如下

1.效果图

2.闪屏页逻辑及布局

2.1 activity_splash.xml

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<FrameLayout 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\">
 
 <ImageView
  android:layout_width=\"match_parent\"
  android:layout_height=\"match_parent\"
  android:src=\"@drawable/splash\"
  android:scaleType=\"centerCrop\"/>
 
 <Button
  android:id=\"@+id/splash_btn_skip\"
  android:layout_width=\"45dp\"
  android:layout_height=\"32dp\"
  android:text=\"跳过\"
  android:textStyle=\"bold\"
  android:textColor=\"#fff\"
  android:background=\"#30000000\"
  android:layout_gravity=\"right\"
  android:layout_marginTop=\"30dp\"
  android:layout_marginRight=\"30dp\"/>
</FrameLayout>

2.2 SplashActivity.java

通过Handler实现

public class SplashActivity extends AppCompatActivity {
 //跳过按钮
 private Button btnSkip;
 private Handler handler = new Handler();
 private Runnable runnableToLogin = new Runnable() {
  @Override
  public void run() {
   toLoginActivity();
  }
 };
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_splash);
 
  initView();
  initEvent();
 
  //延迟4秒
  handler.postDelayed(runnableToLogin,4000);
 
 }
 
 //初始化组件
 public void initView(){
  btnSkip = findViewById(R.id.splash_btn_skip);
 }
 
 //监听事件
 public void initEvent(){
  btnSkip.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    //防止LoginActivity被打开两次
    handler.removeCallbacks(runnableToLogin);
    toLoginActivity();
   }
  });
 }
 
 /**
  * 跳转到登录界面
  */
 private void toLoginActivity(){
  Intent intent = new Intent(this,LoginActivity.class);
  startActivity(intent);
  finish();
 }
 
 @Override
 protected void onDestroy() {
  super.onDestroy();
  //防止内存泄漏
  handler.removeCallbacks(runnableToLogin);
 }
}

3.设置主题样式

3.1 style.xml中

<resources>
 
 <!-- Base application theme. -->
 <style name=\"AppTheme\" parent=\"Theme.AppCompat.Light.NoActionBar\">
  <!-- Customize your theme here. -->
  <item name=\"colorPrimary\">@color/colorPrimary</item>
  <item name=\"colorPrimaryDark\">@color/colorPrimaryDark</item>
  <item name=\"colorAccent\">@color/colorAccent</item>
 </style>
 
 <style name=\"AppTheme_FullScreen\" parent=\"AppTheme\">
  <item name=\"android:windowFullscreen\">true</item>
 </style>
</resources>

3.2 AndroidManifest.xml中

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\"
 package=\"com.example.myrestaurant\">
 
 <uses-permission android:name=\"android.permission.INTERNET\" />
 
 <application
  android:allowBackup=\"true\"
  android:icon=\"@mipmap/ic_launcher\"
  android:label=\"@string/app_name\"
  android:roundIcon=\"@mipmap/ic_launcher_round\"
  android:supportsRtl=\"true\"
  android:theme=\"@style/AppTheme\">
  <activity android:name=\".LoginActivity\"></activity>
  <activity android:name=\".SplashActivity\"
   android:theme=\"@style/AppTheme_FullScreen\">
   <intent-filter>
    <action android:name=\"android.intent.action.MAIN\" />
    <category android:name=\"android.intent.category.LAUNCHER\" />
   </intent-filter>
  </activity>
 </application>
 
</manifest>
