本文例項為大家分享了Android實現閃屏頁效果的具體程式碼,供大家參考,具體內容如下
1.效果圖
2.閃屏頁邏輯及佈局
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="跳過" 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
通過Handler實現
public class SplashActivity extends AppCompatActivity { //跳過按鈕 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(); //延遲4秒 handler.postDelayed(runnableToLogin,4000); } //初始化元件 public void initView(){ btnSkip = findViewById(R.id.splash_btn_skip); } //監聽事件 public void initEvent(){ btnSkip.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //防止LoginActivity被開啟兩次 handler.removeCallbacks(runnableToLogin); toLoginActivity(); } }); } /** * 跳轉到登入介面 */ private void toLoginActivity(){ Intent intent = new Intent(this,LoginActivity.class); startActivity(intent); finish(); } @Override protected void onDestroy() { super.onDestroy(); //防止記憶體洩漏 handler.removeCallbacks(runnableToLogin); } }
3.設定主題樣式
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>
