尝试添加启动屏幕

Question

因此，我一直试图在我的android应用程序中添加启动屏幕，但每当我试图运行它时，应用程序总是崩溃。这里是代码``

activity_splash.xml

 <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:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".Splash"
<ImageView
    android:layout_width="250dp"
    android:layout_height="250dp"
    android:id="@+id/imageView"
    android:background="@drawable/cricket"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat" >
    <activity
        android:name=".Splash"
        android:label="Splash"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
    </activity>

</application>

    public class Splash extends AppCompatActivity {
    // Splash screen timer
    private static int SPLASH_TIME_OUT = 3000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        new Handler() {
            public void postDelayed(Runnable runnable, int splashTimeOut) {
            }

            @Override
            public void close() {

            }

            @Override
            public void flush() {

            }

            @Override
            public void publish(LogRecord record) {

            }
        }.postDelayed(new Runnable() {

            /*
             * Showing splash screen with a timer. This will be useful when you
             * want to show case your app logo / company
             */

            @Override
            public void run() {
                // This method will be executed once the timer is over
                // Start your app main activity
                Intent i = new Intent(Splash.this, MainActivity.class);
                startActivity(i);

                // close this activity
                finish();
            }
        }, SPLASH_TIME_OUT);
    }

}

更新处理程序

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);

    new Handler().postDelayed(new Runnable(){
                @Override
                public void run() {
                    Intent i = new Intent(Splash.this, MainActivity.class);
                startActivity(i);
                finish();

            }, SPLASH_DISPLAY_LENGTH);
}
